CL-1 SAFETY CONSIDERATIONS Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment. Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply. Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguishers available for all brazing operations. Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve damage resulting in hazardous condition. If gas valve is ever subjected to pressure greater than 1/2 psig, it must be replaced before use. When pressure testing field-supplied gas piping at pressures of 1/2 psig or less, a unit connected to such piping must be isolated by manually closing the gas valve(s). Before performing service or maintenance operations on unit, turn off main power switch to unit, install lockout tag. Ensure voltage listed on unit data plate agrees with electrical supply provided for the unit. Electrical shock could cause personal injury. INSTALLATION Unit is shipped in the vertical discharge configuration. To convert to horizontal configuration, remove screws from side duct opening covers and remove covers. Using the same screws, install covers on vertical duct openings with the insulation side down. Seals around duct openings must be tight. See Fig. 1. Confirm before installation of unit that voltage, amperage and circuit protection requirements listed on unit data plate agree with power supply provided. Step 1 — Provide Unit Support ROOF CURB — Assemble and install accessory roof curb in accordance with instructions shipped with curb. See Fig. 2. Install insulation, cant strips, roofing felt, and counter flashing as shown. Ductwork must be attached to curb. If gas or electrical connections are to be routed through the curb, attach the accessory thru-the-curb service connection plate to the roof curb in accordance with the accessory installation instructions. Connections must be installed before unit is set in roof curb. IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasket supplied with the roof curb as shown in Fig. 2. Improperly applied gasket can also result in air or water leaks and poor unit performance. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Catalog No. 04-53480015-01 Printed in U.S.A. Form 48T-6SI Pg 1 9-05 Replaces: 48T-4SI Book 1 4 Tab 1a 6a Curb should be level. Unit leveling tolerances are shown in Fig. 3. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required. If gas or electrical connections are to be routed through the bottom of the unit, attach accessory thru-the-bottom service connections to the basepan in accordance with the accessory installation instructions. ALTERNATE UNIT SUPPORT — When the curb or adapter cannot be used, support unit with sleepers using unit curb or adapter support area. If sleepers cannot be used, support long sides of unit with a minimum of three 4-in. x 4-in. pads, 2 at the corners and one at the unit’s center of gravity. If more than 3 pads are used, equally space the pads along the sides of the unit. SLAB MOUNT (Horizontal Units Only) — Provide a level concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a 6-in. gravel apron in front of condenser coil air inlet to prevent grass and foliage from obstructing airflow. NOTE: Horizontal units may be installed on a roof curb if required. A minimum clearance is not required around ductwork. Cabinet return-air static pressure (a negative condition) should not exceed 0.35 in. wg with economizer or 0.45 in. wg without economizer. These units are designed for a minimum heating operation continuous return-air temperature of 50 F (dry bulb), or an intermittent operation down to 45 F (dry bulb), such as when used with a night set-back thermostat. To operate at lower return-air temperatures, a field-supplied outdoor-air temperature control must be used to initiate both stages of heat when the temperature is below 45 F. Indoor comfort may be compromised when these lower air temperatures are used with insufficient heating temperature rise. Step 3 — Install External Trap for Condensate Drain — The unit’s 3/4-in. condensate drain connections are located on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection can be used with vertical or horizontal applications. When using the standard side drain connection, make sure the plug (Red) in the alternate bottom connection is tight before installing the unit. To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug (Red) from the bottom connection to the side connection. See Fig. 4. The piping for the condensate drain and external trap can be completed after the unit is in place. See Fig. 5. All units must have an external trap for condensate drainage. Install a trap a minimum of 4-in. deep and protect against freeze-up. If drain line is installed downstream from the external trap, pitch the line away from the unit at 1 in. per 10 ft of run. Do not use a pipe size smaller than the unit connection (3/4 in.). The center drain plug looks like a star connection, however it can be removed with a 1/2 in. socket drive extension. Step 2 — Field Fabricate Ductwork — Secure all ducts to roof curb and building structure on vertical units. Do not connect ductwork to unit. For horizontal applications, fieldsupplied flanges should be attached to horizontal discharge openings and all ductwork secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes. Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier. If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes. Fig. 1 — Horizontal Conversion Panels 2 Fig. 2 — Roof Curb Details 3 Step 4 — Rig and Place Unit — Inspect unit for transportation damage. File any claim with transportation agency. Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit. Rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Tables 1A and 1B and Fig. 6 for additional information. Operating weight is shown in Tables 1A and 1B and Fig. 6. Lifting holes are provided in base rails as shown in Fig. 6, 7A and 7B. Refer to rigging instructions on unit. Flue vent discharge must have a minimum horizontal clearance of 48 in. from electric and gas meters, gas regulators, and gas relief equipment. Flue gas can deteriorate building materials. Orient unit so that flue gas will not affect building materials. Adequate combustion-air space must be provided for proper operation of this equipment. Be sure that installation complies with all local codes and Section 5.3, Air for Combustion and Ventilation, NFGC (National Fuel Gas Code), ANSI (American National Standards Institute) Z223.1-latest year and addendum Z223.1A-latest year. In Canada, installation must be in accordance with the CAN1. B149.1 and CAN1.B149.2 installation codes for gas burning appliances. All panels must be in place when rigging and lifting. Unit is not designed for handling by a fork truck. Damage to unit may result. POSITIONING — Maintain clearance around and above unit to provide minimum distance from combustible materials, proper airflow, and service access. See Fig. 7A and 7B Notes. Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contaminated air. Be sure that unit is installed so that snow will not block the combustion intake or flue outlet. Unit may be installed directly on wood flooring or on Class A, B, or C roof-covering material when roof curb is used. Although unit is weatherproof, guard against water from higher level runoff and overhangs. Position unit on roof curb so that the following clearances are maintained: 1/4-in. clearance between roof curb and base rails on each side and duct end of unit; 35/16-in. clearance between roof curb and condenser section end. (See Fig. 2, section C-C.) Locate mechanical draft system flue assembly at least 48 in. from an adjacent building or combustible material. When unit is located adjacent to public walkways, flue assembly must be at least 7 ft above grade. HORIZONTAL DRAIN OUTLET DRAIN PLUG NOTE: Drain plug is shown in factory-installed position. Fig. 4 — Condensate Drain Pan (Side View) MAXIMUM ALLOWABLE DIFFERENCE (in.) A-B 0.5 B-C 1.0 A-C 1.0 NOTE: Trap should be deep enough to offset maximum unit static difference. A 4-in. trap is recommended. Fig. 5 — Condensate Drain Piping Details Fig. 3 — Unit Leveling Tolerances 4 NOTES: 1. Dimension in ( ) is in millimeters. 2. Hook rigging shackles through holes in base rail as shown in detail ‘‘A.’’ Holes in base rails are centered around the unit center of gravity. Use wooden top skid when rigging to prevent rigging straps from damaging unit. 3. Weights include base unit without economizer. See Tables 1A and 1B for economizer weights. 48TF, 48TM UNIT SIZE 008 009 012 014 All panels must be in place when rigging. Unit is not designed for handling by a fork truck.

Remove from shipping location and, using screws provided, install flue hood and screen in location shown in Fig. 8. Step 6 — Install Gas Piping — Unit is equipped for use with type of gas shown on nameplate. Refer to local building codes, or in the absence of local codes, to ANSI Z223.1-latest year and addendum Z223.1A-latest year entitled National Fuel Gas Code. In Canada, installation must be in accordance with the CAN1.B149.1 and CAN1.B149.2 installation codes for gas burning appliances when installing gas piping. For natural gas applications, gas pressure at unit gas connection must not be less than 4.0 in. wg (5.0 in. wg in high heat units) or greater than 13.0 in. wg while unit is operating. For liquid propane applications, the gas pressure must not be less than 5.0 in. wg or greater than 13.0 in. wg at the unit connection. Size gas supply piping for 0.5 in. wg maximum pressure drop. Do not use supply pipe smaller than unit gas connection. LEGEND SPACING OF SUPPORTS NFGC — National Fuel Gas Code STEEL PIPE X *Field supplied.

(feet) (in.) 1/ 6 2 3/4 or 1 8 11/4 or larger 10 Fig. 9 — Gas Piping Guide (With Accessory Thru-the-Curb Service Connections) When connecting gas piping to gas valve inlet, use properly sized back-up wrench to prevent valve damage. FIELD POWER SUPPLY — All units except 208/230-v units are factory wired for the voltage shown on the nameplate. If the 208/230-v unit is to be connected to a 208-v power supply, the transformer must be rewired by moving the black wire from the 230-v 1/4-in. spade terminal on the transformer and connecting it to the 208-v 1/4-in. spade terminal from the transformer. Refer to unit label diagram for additional information. Pigtails are provided for field service. When installing units, provide a disconnect per NEC. Use copper conductors only when splice connectors are used. All field wiring must comply with NEC and local requirements. In Canada, electrical connections must be in accordance with CSA (Canadian Standards Association) C22.1 Canadian Electrical Code Part One. Install conduit through side panel openings indicated in Fig. 7A and 7B. Route power lines through connector to terminal connections as shown in Fig. 10. On 3-phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the formula shown in Tables 2A-2D, Note 2 to determine the percentage of voltage imbalance. Operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Carrier warranty. NOTE: If field-installed thru-the-bottom connections are used, refer to the accessory installation instructions for power wiring and gas connections. Refer to Fig. 7A and 7B for drilling holes in basepan. FIELD CONTROL WIRING — Install a Carrier-approved accessory thermostat assembly according to installation instructions included with the accessory. Locate thermostat assembly on a solid wall in the conditioned space to sense average temperature in accordance with thermostat installation instructions. NOTE: For wire runs up to 50 ft, use no. 18 AWG (American Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft, use no. 16 AWG insulated wire (35 C minimum). For over 75 ft, use no. 14 AWG insulated wire (35 C minimum). All wire larger than no. 18 AWG cannot be directly connected to the thermostat and will require a junction box and splice at the thermostat. Support gas piping as shown in the table in Fig. 9. For example, a 3/4-in. gas pipe must have one field-fabricated support beam every 8 ft. See Fig. 9 for typical pipe guide and locations of external manual gas shutoff valve. NOTE: If field-installed thru-the-bottom connections are used, refer to the accessory installation instructions for power wiring and gas connections. Refer to Fig. 7A and 7B for drilling holes in basepan. Step 7 — Make Electrical Connections Unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal injury if an electrical fault should occur. This ground may consist of electrical wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when installed in accordance with NEC (National Electrical Code), ANSI/NFPA (National Fire Protection Association), latest edition, and local electrical codes. Do not use gas piping as an electrical ground. Failure to follow this warning could result in the installer being liable for personal injury of others. Fig. 8 — Flue Hood Details 12 Route thermostat cable or equivalent single leads of colored wire from thermostat subbase terminals to low-voltage connections on unit (shown in Fig. 11A and 11B) as described in Steps 1-4 below. 1. If unit is mounted on roof curb and accessory thru-thecurb service plate connection is used, route wire through connection plate. 2. Pass control wires through the hole provided on unit (see connection D in Connection Sizes table in Fig. 7A and 7B). 3. Feed wires through the raceway built into the corner post to the 24-v barrier located on the left side of the control box. See Fig. 12. The raceway provides the UL-required (Underwriters’ Laboratories) clearance between highand low-voltage wiring. 4. Connect thermostat wires to screw terminals on lowvoltage connection board.

OUTDOOR AIR OPENING PANEL 3 SCREWS (SIDE) Fig. 13 — Damper Panel with Manual Outdoor-Air Damper Installed 18 PREMIERLINK™ CONTROL — The PremierLink controller is compatible with Carrier Comfort Network® (CCN) devices. This control is designed to allow users the access and ability to change factory-defined settings, thus expanding the function of the standard unit control board. Carrier’s diagnostic standard tier display tools such as Navigator™ or Scrolling Marquee can be used with the PremierLink controller. The PremierLink controller (see Fig. 17A and 17B) requires the use of a Carrier electronic thermostat or a CCN connection for time broadcast to initiate its internal timeclock. This is necessary for broadcast of time of day functions (occupied/ unoccupied). No sensors are supplied with the field-mounted PremierLink control. The factory-installed PremierLink control includes only the supply-air sensor (SAT) and the outdoor air temperature sensor (OAT) as standard. An indoor air quality (CO2) sensor can be added as an option. Refer to Table 3 for sensor usage. Refer to Fig. 18 for PremierLink controller wiring. The PremierLink control may be mounted in the control panel or an area below the control panel. NOTE: PremierLink controller versions 1.3 and later are shipped in Sensor mode. If used with a thermostat, the PremierLink controller must be configured to Thermostat mode. Install the Supply Air Temperature Sensor (SAT) — When the unit is supplied with a factory-mounted PremierLink control, the supply-air temperature (SAT) sensor (33ZCSENSAT) is factory-supplied and wired. The wiring is routed from the PremierLink control over the control box, through a grommet, into the fan section, down along the back side of the fan, and along the fan deck over to the supply-air opening. The SAT probe is wire-tied to the supply-air opening (on the horizontal opening end) in its shipping position. Remove the sensor for installation. Re-position the sensor in the flange of the supply-air opening or in the supply air duct (as required by local codes). Drill or punch a 1/2-in. hole in the flange or duct. Use two field-supplied, self-drilling screws to secure the sensor probe in a horizontal orientation. NOTE: The sensor must be mounted in the discharge airstream downstream of the cooling coil and any heating devices. Be sure the probe tip does not come in contact with any of the unit or heat surfaces. Outdoor Air Temperature Sensor (OAT) — When the unit is supplied with a factory-mounted PremierLink control, the outdoor-air temperature sensor (OAT) is factory-supplied and wired. Install the Indoor Air Quality (CO2) Sensor — Mount the optional indoor air quality (CO2) sensor according to manufacturer specifications. A separate field-supplied transformer must be used to power the CO2 sensor. Wire the CO2 sensor to the COM and IAQI terminals of J5 on the PremierLink controller.

Some modes of operation may require different sensors. Refer to Table 5. The EconoMi$er IV is supplied from the factory with a supply air temperature sensor and an outdoor air temperature sensor. This allows for operation of the EconoMi$er IV with outdoor air dry bulb changeover control. Additional accessories can be added to allow for different types of changeover control and operation of the EconoMi$er IV and unit. Supply Air Temperature (SAT) Sensor — The supply air temperature sensor is a 3 K thermistor located at the inlet of the indoor fan. See Fig. 33. This sensor is factory installed. The operating range of temperature measurement is 0° to 158 F. See Table 4 for sensor temperature/resistance values. The temperature sensor looks like an eyelet terminal with wires running to it. The sensor is located in the “crimp end” and is sealed from moisture.

Outdoor Dry Bulb Changeover — The standard controller is shipped from the factory configured for outdoor dry bulb changeover control. The outdoor air and supply air temperature sensors are included as standard. For this control mode, the outdoor temperature is compared to an adjustable set point selected on the control. If the outdoor-air temperature is above the set point, the EconoMi$er IV will adjust the outdoor air dampers to minimum position. If the outdoor-air temperature is below the set point, the position of the outdoor air dampers will be controlled to provide free cooling using outdoor air. When in this mode, the LED next to the free cooling set point potentiometer will be on. The changeover temperature set point is controlled by the free cooling set point potentiometer located on the control. See Fig. 34. The scale on the potentiometer is A, B, C, and D. See Fig. 35 for the corresponding temperature changeover values. Differential Dry Bulb Control — For differential dry bulb control the standard outdoor dry bulb sensor is used in conjunction with an additional accessory dry bulb sensor (part number CRTEMPSN002A00). The accessory sensor must be mounted in the return airstream. See Fig. 36. Wiring is provided in the EconoMi$er IV wiring harness. See Fig. 28. In this mode of operation, the outdoor air temperature is compared to the return air temperature and the lower temperature air stream is used for cooling. When using this mode of changeover control, turn the enthalpy setpoint potentiometer fully clockwise to the D setting. See Fig. 34. SUPPLY AIR TEMPERATURE SENSOR MOUNTING LOCATION SUPPLY AIR TEMPERATURE SENSOR Fig. 33 — Supply Air Sensor Location Outdoor Air Lockout Sensor — The Economi$er IV is equipped with an ambient temperature lockout switch located in the outdoor air stream which is used to lockout the compressors below a 42 F ambient temperature. See Fig. 21. ECONOMI$ER IV CONTROL MODES IMPORTANT: The optional EconoMi$er2 does not include a controller. The EconoMi$er2 is operated by a 4 to 20 mA signal from an existing field-supplied controller (such as PremierLink™ control). See Fig. 29 for wiring information. 26 Outdoor Enthalpy Changeover — For enthalpy control, accessory enthalpy sensor (part number HH57AC074) is required. Replace the standard outdoor dry bulb temperature sensor with the accessory enthalpy sensor in the same mounting location. See Fig. 21. When the outdoor air enthalpy rises above the outdoor enthalpy changeover set point, the outdoorair damper moves to its minimum position. The outdoor enthalpy changeover set point is set with the outdoor enthalpy set point potentiometer on the EconoMi$er IV controller. The set points are A, B, C, and D. See Fig. 37. The factory-installed 620-ohm jumper must be in place across terminals SR and SR+ on the EconoMi$er IV controller. See Fig. 21 and 38. Differential Enthalpy Control — For differential enthalpy control, the EconoMi$er IV controller uses two enthalpy sensors (HH57AC078 and CRENTDIF004A00), one in the outside air and one in the return air duct. The EconoMi$er IV controller compares the outdoor air enthalpy to the return air enthalpy to determine EconoMi$er IV use. The controller selects the lower enthalpy air (return or outdoor) for cooling. For example, when the outdoor air has a lower enthalpy than the return air, the EconoMi$er IV opens to bring in outdoor air for free cooling. Replace the standard outside air dry bulb temperature sensor with the accessory enthalpy sensor in the same mounting location. See Fig. 21. Mount the return air enthalpy sensor in the return air duct. See Fig. 36. Wiring is provided in the EconoMi$er IV wiring harness. See Fig. 28. The outdoor enthalpy changeover set point is set with the outdoor enthalpy set point potentiometer on the EconoMi$er IV controller. When using this mode of changeover control, turn the enthalpy setpoint potentiometer fully clockwise to the D setting. Indoor Air Quality (IAQ) Sensor Input — The IAQ input can be used for demand control ventilation control based on the level of CO2 measured in the space or return air duct. Mount the accessory IAQ sensor according to manufacturer specifications. The IAQ sensor should be wired to the AQ and AQ1 terminals of the controller. Adjust the DCV potentiometers to correspond to the DCV voltage output of the indoor air quality sensor at the user-determined set point. See Fig. 39. If a separate field-supplied transformer is used to power the IAQ sensor, the sensor must not be grounded or the EconoMi$er IV control board will be damaged.

Thermostats — The EconoMi$er IV control works with conventional thermostats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (heat stage 1), W2 (heat stage 2), and G (fan). The EconoMi$er IV control does not support space temperature sensors. Connections are made at the thermostat terminal connection board located in the main control box. Occupancy Control — The factory default configuration for the EconoMi$er IV control is occupied mode. Occupied status is provided by the black jumper from terminal TR to terminal N. When unoccupied mode is desired, install a field-supplied timeclock function in place of the jumper between TR and N. See Fig. 28. When the timeclock contacts are closed, the EconoMi$er IV control will be in occupied mode. When the timeclock contacts are open (removing the 24-v signal from terminal N), the EconoMi$er IV will be in unoccupied mode. Demand Controlled Ventilation (DCV) — When using the EconoMi$er IV for demand controlled ventilation, there are some equipment selection criteria which should be considered. When selecting the heat capacity and cool capacity of the equipment, the maximum ventilation rate must be evaluated for design conditions. The maximum damper position must be calculated to provide the desired fresh air. Typically the maximum ventilation rate will be about 5 to 10% more than the typical cfm required per person, using normal outside air design criteria. A proportional anticipatory strategy should be taken with the following conditions: a zone with a large area, varied occupancy, and equipment that cannot exceed the required ventilation rate at design conditions. Exceeding the required ventilation rate means the equipment can condition air at a maximum ventilation rate that is greater than the required ventilation rate for maximum occupancy. A proportional-anticipatory strategy will cause the fresh air supplied to increase as the room CO2 level increases even though the CO2 set point has not been reached. By the time the CO2 level reaches the set point, the damper will be at maximum ventilation and should maintain the set point. In order to have the CO2 sensor control the economizer damper in this manner, first determine the damper voltage output for minimum or base ventilation. Base ventilation is the ventilation required to remove contaminants during unoccupied periods. The following equation may be used to determine the percent of outside-air entering the building for a given damper position. For best results there should be at least a 10 degree difference in outside and return-air temperatures. OA RA (TO x ) + (TR x ) = TM 100 100 TO = Outdoor-Air Temperature OA = Percent of Outdoor Air TR = Return-Air Temperature RA = Percent of Return Air TM = Mixed-Air Temperature Once base ventilation has been determined, set the minimum damper position potentiometer to the correct position. The same equation can be used to determine the occupied or maximum ventilation rate to the building. For example, an output of 3.6 volts to the actuator provides a base ventilation rate of 5% and an output of 6.7 volts provides the maximum ventilation rate of 20% (or base plus 15 cfm per person). Use Fig. 39 to determine the maximum setting of the CO2 sensor. For example, a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 39 to find the point when the CO2 sensor output will be 6.7 volts. Line up the point on the graph with the left side of the chart to determine that the range configuration for the CO2 sensor should be 1800 ppm. The EconoMi$er IV controller will output the 6.7 volts from the CO2 sensor to the actuator when the CO2 concentration in the Exhaust Set Point Adjustment — The exhaust set point will determine when the exhaust fan runs based on damper position (if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer. See Fig. 34. The set point represents the damper position above which the exhaust fans will be turned on. When there is a call for exhaust, the EconoMi$er IV controller provides a 45 ± 15 second delay before exhaust fan activation to allow the dampers to open. This delay allows the damper to reach the appropriate position to avoid unnecessary fan overload. Minimum Position Control — There is a minimum damper position potentiometer on the EconoMi$er IV controller. See Fig. 34. The minimum damper position maintains the minimum airflow into the building during the occupied period. When using demand ventilation, the minimum damper position represents the minimum ventilation position for VOC (volatile organic compound) ventilation requirements. The maximum demand ventilation position is used for fully occupied ventilation. When demand ventilation control is not being used, the minimum position potentiometer should be used to set the occupied ventilation position. The maximum demand ventilation position should be turned fully clockwise. Adjust the minimum position potentiometer to allow the minimum amount of outdoor air, as required by local codes, to enter the building. Make minimum position adjustments with at least 10 F temperature difference between the outdoor and return-air temperatures. To determine the minimum position setting, perform the following procedure: 1. Calculate the appropriate mixed air temperature using the following formula: OA RA ) + (TR x ) = TM (TO x 100 100 TO = Outdoor-Air Temperature OA = Percent of Outdoor Air TR = Return-Air Temperature RA = Percent of Return Air TM = Mixed-Air Temperature As an example, if local codes require 10% outdoor air during occupied conditions, outdoor-air temperature is 60 F, and return-air temperature is 75 F. (60 x .10) + (75 x .90) = 73.5 F 2. Disconnect the supply air sensor from terminals T and T1. 3. Ensure that the factory-installed jumper is in place across terminals P and P1. If remote damper positioning is being used, make sure that the terminals are wired according to Fig. 28 and that the minimum position potentiometer is turned fully clockwise. 4. Connect 24 vac across terminals TR and TR1. 5. Carefully adjust the minimum position potentiometer until the measured supply air temperature matches the calculated value. 6. Reconnect the supply air sensor to terminals T and T1. Remote control of the EconoMi$er IV damper is desirable when requiring additional temporary ventilation. If a field-supplied remote potentiometer (Honeywell part number S963B1128) is wired to the EconoMi$er IV controller, the minimum position of the damper can be controlled from a remote location. To control the minimum damper position remotely, remove the factory-installed jumper on the P and P1 terminals on the EconoMi$er IV controller. Wire the field-supplied potentiometer to the P and P1 terminals on the EconoMi$er IV controller. See Fig. 38. 29 Step 9 — Adjust Evaporator-Fan Speed — Ad- space is at 1100 ppm. The DCV set point may be left at 2 volts since the CO2 sensor voltage will be ignored by the EconoMi$er IV controller until it rises above the 3.6 volt setting of the minimum position potentiometer. Once the fully occupied damper position has been determined, set the maximum damper demand control ventilation potentiometer to this position. Do not set to the maximum position as this can result in over-ventilation to the space and potential high-humidity levels. CO 2 Sensor Configuration — The CO2 sensor has preset standard voltage settings that can be selected anytime after the sensor is powered up. See Table 6. Use setting 1 or 2 for Carrier equipment. See Table 6. 1. Press Clear and Mode buttons. Hold at least 5 seconds until the sensor enters the Edit mode. 2. Press Mode twice. The STDSET Menu will appear. 3. Use the Up/Down button to select the preset number. See Table 6. 4. Press Enter to lock in the selection. 5. Press Mode to exit and resume normal operation. The custom settings of the CO2 sensor can be changed anytime after the sensor is energized. Follow the steps below to change the non-standard settings: 1. Press Clear and Mode buttons. Hold at least 5 seconds until the sensor enters the Edit mode. 2. Press Mode twice. The STDSET Menu will appear. 3. Use the Up/Down button to toggle to the NONSTD menu and press Enter. 4. Use the Up/Down button to toggle through each of the nine variables, starting with Altitude, until the desired setting is reached. 5. Press Mode to move through the variables. 6. Press Enter to lock in the selection, then press Mode to continue to the next variable. Dehumidification of Fresh Air with DCV Control — Information from ASHRAE indicates that the largest humidity load on any zone is the fresh air introduced. For some applications, a device such as a 62AQ energy recovery unit is added to reduce the moisture content of the fresh air being brought into the building when the enthalpy is high. In most cases, the normal heating and cooling processes are more than adequate to remove the humidity loads for most commercial applications. If normal rooftop heating and cooling operation is not adequate for the outdoor humidity level, an energy recovery unit and/or a dehumidification option should be considered. just evaporator-fan speed to meet jobsite requirement. Table 7 shows fan rpm at motor pulley settings, Table 8 shows motor efficiencies. Table 9 shows motor performance. Tables 10 and 11 show accessory static pressure. Refer to Fan Performance Tables 12-41 to determine fan speed settings. Fan motor pulleys are factory set for speed shown in Tables 1A and 1B. To change fan speed: 1.

All other rpms require fieldsupplied drive. 62 PRE-START-UP Return-Air Filters — Make sure correct filters are installed in filter tracks (see Tables 1A and 1B). Do not operate unit without return-air filters. Failure to observe the following warnings could result in serious personal injury. 1. Follow recognized safety practices and wear protective goggles when checking or the servicing refrigerant system. 2. Do not operate the compressor or provide any electric power to the unit unless the compressor terminal cover is in place and secured. 3. Do not remove the compressor terminal cover until all electrical sources are disconnected. 4. Relieve all pressure from the system before touching or disturbing anything inside the compressor terminal box if refrigerant leak is suspected around the compressor terminals. 5. Never attempt to repair a soldered connection while the refrigerant system is under pressure. 6. Do not use torch to remove any component. The system contains oil and refrigerant under pressure. To remove a component, wear protective goggles and proceed as follows: a. Shut off gas and then electrical power to the unit. Install lockout tag. b. Relieve all pressure from the system using both high-pressure and low-pressure ports. c. Cut the component connection tubing with a tubing cutter, and remove the component from the unit. d. Carefully unsweat the remaining tubing stubs when necessary. Oil can ignite when exposed to torch flame. Outdoor-Air Inlet Screens — Outdoor-air inlet screens must be in place before operating unit. Compressor Mounting — Compressors are internally spring mounted. Do not loosen or remove compressor holddown bolts. On 48TF,TM014 units, remove the tiedown bands that hold the compressors together. Internal Wiring — Check all electrical connections in unit control boxes. Tighten as required. Ensure wiring does not come into direct contact with refrigerant tubing. Gas Piping — Check gas piping for leaks. Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve damage resulting in hazardous condition. If gas valve is subjected to pressure greater than 1/2 psig, it must be replaced before use. When pressure testing fieldsupplied gas piping at pressures of 1/2 psig or less, a unit connected to such piping must be isolated by manually closing the gas valve. Refrigerant Service Ports — To service refrigerant service ports, remove compressor access panel. Each unit system has 3 Schrader-type service gage ports: one on the suction line, one on the liquid line, and one on the compressor discharge line. Be sure that caps on the ports are tight. The Schrader-type valve on the discharge line is located under the low-pressure switch. Another valve is located on the discharge line underneath the high-pressure switch. It is screwed on a Schrader fitting but there is no Schrader core. Proceed as follows to inspect and prepare the unit for initial start-up: 1. Remove all access panels. 2. Read and follow instructions on all WARNING, CAUTION, and INFORMATION labels attached to, or shipped with, the unit. 3. Make the following inspections: a. Inspect for shipping and handling damages such as broken lines, loose parts, or disconnected wires, etc. b. Inspect for oil at all refrigerant tubing connections and on unit base. Detecting oil generally indicates a refrigerant leak. Leak-test all refrigerant tubing connections using an electronic leak detector, halide torch, or liquid-soap solution. c. Inspect all field-wiring and factory-wiring connections. Be sure that connections are completed and tight. d. Inspect coil fins. If damaged during shipping and handling, carefully straighten the fins with a fin comb. 4. Verify the following conditions: a. Make sure that condenser fan blade is correctly positioned in the fan orifice. See Condenser-Fan Adjustment section on page 68 for more details. b. Make sure that air filter(s) is in place. c. Make sure that condensate drain trap is filled with water to ensure proper drainage. d. Make sure that all tools and miscellaneous loose parts have been removed. High Flow Valves — Located on the compressor hot gas and suction tubes are High Flow Valves. Large black plastic caps distinguish these valves with O-rings located inside the caps. These valves can not be accessed for service in the field. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur. Compressor Rotation — On 3-phase units with scroll compressors, it is important to be certain compressor is rotating in the proper direction. To determine whether or not compressor is rotating in the proper direction: 1. Connect service gages to suction and discharge pressure fittings. 2. Energize the compressor. 3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start-up. If the suction pressure does not drop and the discharge pressure does not rise to normal levels: 1. Note that the evaporator fan is probably also rotating in the wrong direction. 2. Turn off power to the unit and install lockout tag. 3. Reverse any two of the unit power leads. 4. Reapply power to unit. Reenergize compressor. The suction and discharge pressure levels should now move to their normal start-up levels. NOTE: When the compressor is rotating in the wrong direction, the unit will make an elevated level of noise and will not provide cooling. START-UP Unit Preparation — Make sure that unit has been installed in accordance with these installation instructions and applicable codes. Make sure that Start-Up Checklist, located on back page of this booklet, has been completed and filled out. 63 Cooling — To start unit, turn on main power supply. Set system selector switch at COOL position and fan switch at AUTO. position. Adjust thermostat to a setting below room temperature. Compressor, indoor and outdoor fans start on closure of contactors. Check unit charge. Refer to Checking and Adjusting Refrigerant Charge section, page 68. Unit must operate a minimum of 10 minutes before adjusting charge. Reset thermostat at a position above room temperature. Compressor and outdoor fans will shut off. Evaporator fan will shut off after 30-second delay. TO SHUT OFF UNIT — Set system selector switch at OFF position. Resetting thermostat at a position above room temperature shuts unit off temporarily until space temperature exceeds thermostat setting. Heating 1. Purge gas supply line of air by opening union ahead of gas valve. When gas odor is detected, tighten union and wait 5 minutes before proceeding. 2. Turn on electrical supply and open manual gas valve. 3. Set system switch selector at HEAT position and fan switch at AUTO. or ON position. Set heating temperature lever above room temperature. 4. The induced-draft motor will start, purging heat exchangers. 5. After a call for heating, the main burners should light within 5 seconds. If the burners do not light, then there is a 22-second delay before another 5-second ignition try. If the burners still do not light, the time delay is repeated. If the burners do not light within 15 minutes, there is a lockout. To reset the control, break the 24 v power to W1. 6. The evaporator-fan motor will turn on 45 seconds after the burners are ignited. 7. The evaporator-fan motor will turn off 45 seconds after the thermostat temperature is satisfied. 8. Adjust airflow to obtain a temperature rise within the range specified on the unit nameplate and in Tables 1A and 1B. Main Burners — Main burners are factory set and should require no adjustment. TO CHECK ignition of main burners and heating controls, move thermostat set point above room temperature and verify that the burners light and evaporator fan is energized. After ensuring that the unit continues to heat the building, lower the thermostat setting below the room temperature and verify that the burners and evaporator fan turn off (fan will turn off only if fan selector switch is in the AUTO. position). Refer to Table 42 for the correct orifice to use at high altitudes. NOTE: Upon a call for heat, the main burners will remain on for a minimum of 60 seconds. ADJUST GAS INPUT — The gas input to the unit is determined by measuring the gas flow at the meter or by measuring the manifold pressure. Manifold pressure should be 3.5 in. wg. NOTE: On units that use a 2-stage gas valve there is no need to adjust the “Low Fire” manifold pressure. Measure Gas Flow (Natural Gas Units) — Minor adjustment to the gas flow can be made by changing the manifold pressure. The manifold pressure must be 3.5 in wg. Normal manifold pressure is 3.5 in. wg in high fire (W1 and W2 inputs to gas valve). Proceed as follows: 1. Turn off gas supply to unit. 2.

Integrated Gas Controller (IGC) Operation NOTE: The default value for the evaporator-fan motor ON and OFF delay is 45 seconds. The Integrated Gas Controller (IGC) modifies this value when abnormal limit switch cycles occur. Based upon unit operating conditions, the ON delay can be reduced to 0 seconds and the OFF delay can be extended to 180 seconds. When one flash of the LED (light-emitting diode) is observed, the evaporator-fan ON/OFF delay has been modified. If the limit switch trips at the start of the heating cycle during the evaporator ON delay, the time period of the ON delay for the next cycle will be 5 seconds less than the time at which the switch tripped. (Example: If the limit switch trips at 30 seconds, the evaporator-fan ON delay for the next cycle will occur at 25 seconds.) To prevent short-cycling, a 5-second reduction will only occur if a minimum of 10 minutes has elapsed since the last call for heating. Unsafe operation of the unit may result if manifold pressure is outside 3.4 to 3.6 in. wg range. Personal injury or unit damage may result. 3. Replace cover screw cap on gas valve. 4. Turn off gas supply to unit. Remove manometer from pressure tap and replace pipe plug on gas valve. Turn on gas to unit and check for leaks. 64 at the minimum open position. Below 45 F the dampers will be completely shut. As the supply-air temperature rises, the dampers will come back open to the minimum open position once the supply-air temperature rises to 48 F. If optional power exhaust is installed, as the outdoor-air damper opens and closes, the power exhaust fans will be energized and deenergized. If field-installed accessory CO2 sensors are connected to the EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO2 level in the zone increases above the CO2 set point, the minimum position of the damper will be increased proportionally. As the CO2 level decreases because of the increase in fresh air, the outdoor-air damper will be proportionally closed. Damper position will follow the higher demand condition from DCV mode or free cooling mode. Damper movement from full closed to full open (or vice versa) will take between 11/2 and 21/2 minutes. If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve, differential dry bulb, or differential enthalpy), a call for cooling (Y1 closes at the thermostat) will cause the control to modulate the dampers open to maintain the supply air temperature set point at 50 to 55 F. As the supply air temperature drops below the set point range of 50 to 55 F, the control will modulate the outdoor-air dampers closed to maintain the proper supply-air temperature. HEATING, UNITS WITH ECONOMI$ER IV — When the room temperature calls for heat, the heating controls are energized as described in the Heating, Units Without Economizer section. When the thermostat is satisfied, the economizer damper moves to the minimum position. COOLING, UNITS WITH ECONOMI$ER2, PREMIERLINK™ CONTROL AND A THERMOSTAT — When free cooling is not available, the compressors will be controlled by the PremierLink control in response to the Y1 and Y2 inputs from the thermostat. The PremierLink control will use the following information to determine if free cooling is available: • Indoor fan has been on for at least 30 seconds. • The SPT, SAT, and OAT inputs must have valid readings. • OAT must be less than 75 F. • OAT must be less than SPT. • Enthalpy must be LOW (may be jumpered if an enthalpy sensor not available). • Economizer position is NOT forced. Pre-cooling occurs when the is no call from the thermostat except G. Pre-cooling is defined as the economizer modulates to provide 70 F supply air. When free cooling is available the PremierLink control will control the compressors and economizer to provide a supplyair temperature determined to meet the Y1 and Y2 calls from the thermostat using the following three routines. The three control routines are based on OAT. The 3 routines are based on OAT where: SASP = Supply Air Set Point DXCTLO = Direct Expansion Cooling Lockout Set Point PID = Proportional Integral Routine 1 (OAT < DXCTLO) • Y1 energized – economizer maintains a SASP = (SATLO1 + 3). • Y2 energized – economizer maintains a SASP = (SATLO2 + 3). The evaporator-fan OFF delay can also be modified. Once the call for heating has ended, there is a 10-minute period during which the modification can occur. If the limit switch trips during this period, the evaporator-fan OFF delay will increase by 15 seconds on the next cycle. A maximum of 9 trips can occur, extending the evaporator-fan OFF delay to 180 seconds. To restore the original default value, reset the power to the unit. TO SHUT OFF UNIT — Set system selector switch at OFF position. Resetting heating selector lever below room temperature will shut unit off temporarily until space temperature falls below thermostat setting. Safety Relief — A soft-solder joint at the suction line Schrader port provides pressure relief under abnormal temperature and pressure conditions. Ventilation (Continuous Fan) — Set fan and system selector switches at ON and OFF positions, respectively. Evaporator fan operates continuously to provide constant air circulation. When the evaporator-fan selector switch is turned to the OFF position, there is a 30-second delay before the fan turns off. Operating Sequence COOLING, UNITS WITHOUT ECONOMIZER — When thermostat calls for cooling, terminals G and Y1 are energized. The indoor (evaporator) fan contactor (IFC), compressor contactor no. 1 (C1) and outdoor-fan contactor (OFC) are energized, and evaporator-fan motor, compressor no. 1, and both condenser fans start. The condenser-fan motors run continuously while unit is cooling. If the thermostat calls for a second stage of cooling by energizing Y2, compressor contactor no. 2 (C2) is energized and compressor no. 2 starts. When the thermostat is satisfied, C1 and C2 are deenergized and the compressors and outdoor (condenser) fan motors (OFM) shut off. After a 30-second delay, the indoor (evaporator) fan motor (IFM) shuts off. If the thermostat fan selector switch is in the ON position, the evaporator-fan motor will run continuously. HEATING, UNITS WITHOUT ECONOMIZER — When the thermostat calls for heating, terminal W1 is energized. In order to prevent thermostat short-cycling, the unit is locked into the Heating mode for at least 1 minute when W1 is energized. The induced-draft motor (IDM) is then energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after a flame is ignited. On units equipped for two stages of heat, when additional heat is needed, W2 is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 and W2 are deenergized, the IFM stops after a 45-second time-off delay. COOLING, UNITS WITH ECONOMI$ER IV — When free cooling is not available, the compressors will be controlled by the zone thermostat. When free cooling is available, the outdoor-air damper is modulated by the EconoMi$er IV control to provide a 50 to 55 F supply-air temperature into the zone. As the supply-air temperature fluctuates above 55 or below 50 F, the dampers will be modulated (open or close) to bring the supply-air temperature back within the set point limits. For EconoMi$er IV operation, there must be a thermostat call for the fan (G). This will move the damper to its minimum position during the occupied mode. Above 50 F supply-air temperature, the dampers will modulate from 100% open to the minimum open position. From 50 F to 45 F supply-air temperature, the dampers will maintain 65 into the zone. The supply air will maintain the space temperature between the heating and cooling set points as indicated in Fig. 44. The PremierLink will integrate the compressors stages with the economizer based on similar logic as the three routines listed in the previous section. The SASP will float up and down based on the error reduction calculations that compare space temperature and space set point. When outdoor-air temperature conditions require the economizer to close for a compressor stage-up sequence, the economizer control integrator is reset to zero after the stage-up sequence is completed. This prevents the supply-air temperature from dropping too quickly and creating a freeze condition that would make the compressor turn off prematurely. The high space set point is used for DX (direct expansion) cooling control, while the economizer space set point is a calculated value between the heating and cooling set points. The economizer set point will always be at least one degree below the cooling set point, allowing for a smooth transition from mechanical cooling with economizer assist, back to economizer cooling as the cooling set point is achieved. The compressors may be used for initial cooling then the PremierLink controller will modulate the economizer using an error reduction calculation to hold the space temperature between the heating and cooling set points. See Fig. 44. The controller uses the following conditions to determine economizer cooling: • Enthalpy is Low • SAT reading is available • OAT reading is available • SPT reading is available • OAT ≤ SPT • Economizer Position is NOT forced Routine 2 (DXCTLO < OAT < 68 F) • If only Y1 energized, the economizer maintains a SASP = (SATLO1 + 3). • If SAT > SASP + 5 and economizer position > 80%, economizer will go to minimum position for 3 minutes or until SAT > 68 F. • First stage of mechanical cooling will be energized. • Integrator resets. • Economizer opens again and controls to current SASP after stage one on for 90 seconds. • With Y1 and Y2 energized economizer maintains an SASP = SATLO2 + 3. • If SAT > SASP + 5 and economizer position >80%, economizer will go to minimum position for 3 minutes or until SAT > 68 F. • If compressor one is on then second stage of mechanical cooling will be energized. Otherwise the first stage will be energized. • Integrator resets. • Economizer opens again and controls to SASP after stage one on for 90 seconds. Routine 3 (OAT > 68) • Economizer is opened 100%. • Compressors 1 and 2 are cycled based on Y1 and Y2 using minimum on and off times and watching the supply air temperature as compared to SATLO1 and SATLO2 set points. If optional power exhaust is installed, as the outdoor-air damper opens and closes, the power exhaust fans will be energized and deenergized. If field-installed accessory CO2 sensors are connected to the PremierLink™ control, a PID-controlled demand ventilation strategy will begin to operate. As the CO2 level in the zone increases above the CO2 set point, the minimum position of the damper will be increased proportionally. As the CO2 level decreases because of the increase in fresh air, the outdoor-air damper will be proportionally closed. HEATING, UNITS WITH ECONOMI$ER2, PREMIERLINK CONTROL AND A THERMOSTAT — When the thermostat calls for heating, terminal W1 is energized. The PremierLink control will move the economizer damper to the minimum position if there is a call for G and closed if there is a call for W1 without G. In order to prevent thermostat from short cycling, the unit is locked into the heating mode for at least 10 minutes when W1 is energized. The induced-draft motor is then energized and the burner ignition sequence begins. On units equipped for two stages of heat, when additional heat is needed, W2 is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 is deenergized, the IFM stops after a 45-second time-off delay unless G is still maintained. COOLING, UNITS WITH ECONOMI$ER2, PREMIERLINK CONTROL AND A ROOM SENSOR — When free cooling is not available, the compressors will be controlled by the PremierLink controller using a PID Error reduction calculation as indicated by Fig 43. The PremierLink controller will use the following information to determine if free cooling is available: • Indoor fan has been on for at least 30 seconds. • The SPT, SAT, and OAT inputs must have valid readings. • OAT must be less than 75 F. • OAT must be less than SPT. • Enthalpy must be LOW (may be jumpered if and enthalpy sensor is not available). • Economizer position is NOT forced. When free cooling is available, the outdoor-air damper is positioned through the use of a Proportional Integral (PID) control process to provide a calculated supply-air temperature SPACE TEMPERATURE TEMPERATURE CONTROL 75 74 73 72 SET POINT TEMPERATURE 71 70 69 68 TIME NOTE: PremierLink control performs smart staging of 2 stages of DX cooling and up to 3 stages of heat. Fig. 43 — DX Cooling Temperature Control Example SPACE TEMPERATURE TEMPERATURE CONTROL 75 74 73 72 COOL SETPOINT TEMPERATURE HEAT SETPOINT 71 70 69 68 TIME Fig. 44 — Economizer Temperature Control Example 66 If any of the above conditions are not met, the economizer submaster reference (ECSR) is set to maximum limit and the damper moves to minimum position. The operating sequence is complete. The ECSR is recalculated every 30 seconds. If an optional power exhaust is installed, as the outdoor-air damper opens and closes, the power exhaust fans will be energized and deenergized. If field-installed accessory CO2 sensors are connected to the PremierLink™ control, a PID-controlled demand ventilation strategy will begin to operate. As the CO2 level in the zone increases above the CO2 set point, the minimum position of the damper will be increased proportionally. As the CO2 level decreases because of the increase in fresh air, the outdoor-air damper will be proportionally closed. HEATING, UNIT WITH ECONOMI$ER2, PREMIERLINK CONTROL AND A ROOM SENSOR — Every 40 seconds the controller will calculate the required heat stages (maximum of 3) to maintain supply air temperature (SAT) if the following qualifying conditions are met: • Indoor fan has been on for at least 30 seconds. • COOL mode is not active. • OCCUPIED, TEMP.COMPENSATED START or HEAT mode is active. • SAT reading is available. • Fire shutdown mode is not active. If all of the above conditions are met, the number of heat stages is calculated; otherwise the required number of heat stages will be set to 0. If the PremierLink controller determines that heat stages are required, the economizer damper will be moved to minimum position if occupied and closed if unoccupied. Staging should be as follows: If Heating PID STAGES=2 • HEAT STAGES=1 (50% capacity) will energize HS1 • HEAT STAGES=2 (100% capacity) will energize HS2 If Heating PID STAGES=3 and AUXOUT = HS3 • HEAT STAGES=1 (33% capacity) will energize HS1 • HEAT STAGES=2 (66% capacity) will energize HS2 • HEAT STAGES=3 (100% capacity) will energize HS3 In order to prevent short cycling, the unit is locked into the Heating mode for at least 10 minutes when HS1 is deenergized. When HS1 is energized the induced-draft motor is then energized and the burner ignition sequence begins. On units equipped for two stages of heat, when additional heat is needed, HS2 is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the space condition is satisfied and HS1 is deenergized the IFM stops after a 45-second time-off delay unless in the occupied mode. The fan will run continuously in the occupied mode as required by national energy and fresh air standards. 2.

This switch opens at 428 psig and closes at 320 psig. No adjustment is necessary. Refer to Tables 1A and 1B. Loss-of-Charge Switch — Located on the condenser liquid line is a low-pressure switch which functions as a lossof-charge switch. This switch contains a Schrader core depressor. This switch opens at 7 psig and closes at 22 psig. No adjustment is necessary. Refer to Tables 1A and 1B. Freezestat — Located on the “hair pin” end of the evaporator coil is a bimetal temperature sensing switch. This switch protects the evaporator coil from freeze-up due to lack of airflow. The switch opens at 30 F and closes at 45 F. No adjustment is necessary. Refer to Tables 1A and 1B. Checking and Adjusting Refrigerant Charge — The refrigerant system is fully charged with R-22 refrigerant, tested, and factory-sealed. Unit must operate in Cooling mode a minimum of 10 minutes before checking charge. NOTE: Adjustment of the refrigerant charge is not required unless the unit is suspected of not having the proper R-22 charge. A superheat charging chart is attached to the outside of the service access panel. The chart includes the required suction line temperature at given suction line pressures and outdoor ambient temperatures. An accurate superheat, thermocouple-type or thermistortype thermometer, and a gage manifold are required when using the superheat charging method for evaluating the unit charge. Do not use mercury or small dial-type thermometers because they are not adequate for this type of measurement. Fig. 47 — Separating Coil Sections Lubrication COMPRESSORS — Each compressor is charged with the correct amount of oil at the factory. FAN-MOTOR BEARINGS — Fan-motor bearings are of the permanently lubricated type. No further lubrication is required. No lubrication of condenser-fan or evaporator-fan motors is required. When evaluating the refrigerant charge, an indicated adjustment to the specified factory charge must always be very minimal. If a substantial adjustment is indicated, an abnormal condition exists somewhere in the cooling system, such as insufficient airflow across either coil or both coils.

Evaporator inlet-air temperature (F wb). c. Suction-tube temperature (F) at low-side service fitting. d. Suction (low-side) pressure (psig). FAN HEIGHT “A” (in.) 2.75 3.50 Fig. 48 — Condenser-Fan Adjustment 68 5. Using “Cooling Charging Charts” compare outdoor-air temperature (F db) with the suction line pressure (psig) to determine desired system operating suction line temperature. See Fig. 49-56. 6. Compare measured suction-tube temperature with desired suction-tube temperature. Using a tolerance of ± 3° F, add refrigerant if measured temperature is more than 3° F higher than proper suction-tube temperature, or remove refrigerant if actual temperature is more than 3° F lower than required suction-tube temperature. TO USE COOLING CHARGING CHART — This method is to be used in Cooling mode only. Take the outdoor ambient temperature and read the suction pressure gage. Refer to appropriate chart to determine what suction temperature should be. If suction temperature is high, add refrigerant. If suction temperature is low, carefully recover some of the charge.
