SAFETY
CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electric_d components. Only trained and qualified service personnel should
install, repair, or service at>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 at>conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and
other safety precautions that 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.
Manufacturer
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.
Before performing service or maintenance
operations on
unit, turn off main power switch to unit and install a lockout tag. Electrical shock could c_mse personal injury.
INSTALLATION
Unit is shipped in the vertical duct configuration. To convert
to horizont_d configuration, remove and save screws fi_m side
duct opening covers and remove covers. Using the same
screws, install covers on veriical duct openings with the
insulation-side down. Seals around duct openings must be
tight. See Fig. 1.
Confimt before installation of unit that voltage, mnperage
and circuit protection requirements listed on unit &tta plate
agree with power supply provided.
Step 1 -- Provide
ROOF CURB -- Assemble and install accesso U roof curb in
accor&mce 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, not to the unit.
The accesso O" thru-the-boltom power and gas connection package must be installed b@re the unit is ,wt on the roo/ curb. If
field-installed (thin-the-roof curb) gas connections tue desired,
use factory-supplied
3/4-in. pipe coupling and gas plate assembly to mount the thin-the-roof curb connection to the roof crag.
Gas connections and power connections to the unit must be
field installed after the unit is installed on the roof curb.
If electric and control wiring is to be routed through
the basepan,
attach the accessory thru-the-bottom
service
connections to the basepan in accordance with the accessory
installation instructions.

IMPORTANT: Tile gasketing of tile unit to tile roof curb is ]
critical for a watertight seal. Install gasket supplied with the
roof curb as shown in Fig. 2. hnproperly applied gasket can
result in tdr leaks and pool unit performance.

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 lequiled.
SLAB MOUNT (Horizontal
Units Only) -- Provide a level
conclete slab that extends a minimum of 6 in. beyond unit

Field Fabricate
These units tue designed for a minimum continuous heating
return-air temperature of 50 F (dry bulb), or an intermittent
operation down to 45 F (@ 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 E 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 deterraine the use of drain connections; either
dnun connection
can be used with vertic;d or horizont;d
applications.
ALTERNATE UNIT SUPPORT (Curb or Slab Mount) -- A
non-combustible
sleeper rail can be used in the unit curb support tuea. If sleeper rails cannot be used, support the long sides
of the unit with a minimum of 3 equally spaced 4-in. x 4-in.

Step 2 --
A minimum clearance is not required around ductwork.

When using the standard side &'ain connection, make sure
the plug (Red) in the ;alternate bottom connection is tight before
inst;dling 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. The center &'ain plug looks
like a stm" connection, however it can be removed with a l/2-in.
socket drive extension. See Fig. 4A. The piping for the condensate &'ain and external trap can be completed after the unit is in
place. See Fig. 4B.
Ductwork
-- Secure all
ducts to roof curb and building structure on vertical ducted
units. Do not connect du(_'ork to unit. For horizontal applications, field-supplied flanges should be attached to horizontal
duct openings and all ductwork should be secured to the
flanges. Insulate and weatherproof
all external ductwork,
joints, and roof openings with counter flashing and mastic in
accor&mce with applicable codes.

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
entitled National Fuel Gas Code. In Cana&t, installation must
be in accordance with the CANI.BI49A
and CANI.BI49.2
installation codes for gas burning appliances.
Be sure that unit is installed such 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,
higher level runoff and overhangs.

For natural gas applications, gas pressuw at unit gas connection must not be less titan 4 in. wg or greaWr than
13.0 in. wg while unit is operating. On 48TF005,006,007
high
heat units, the gas pressure at unit gas connection must not be
less than 5 in. wg or greater than 13 in. wg while the unit is
operating. For propane applications, the gas pressure must not
be less than 5 in. wg or greater than 13 in. wg at the unit
connection.

Minimum distance between unit and other electrically live
parts is 48 inches.
Size gas supply piping .fbr 0.5 in. wg maximum pressure
drop. Do not use supply pipe smNler titan unit gas connection.
Support gas piping as shown in the table in Fig. 8. For example, a 3h-in. gas pipe must have one field-fabricated
support
beam every 8 ft. Therefore, an 18-1l long gas pipe would have a
minimum of 2 support beams, a 48-ft long pipe would have a
minimum of 6 support beams.
Flue gas can deteriorate building materials. Orient unit
such that flue gas will not affect building materials. Locate
mechanical draft system flue assembly at least 48 in. fiom an
adjacent building or combustible materi_d.
Adequate combustion-air and ventilation-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), and ANSI (American
National Stan&rds
Institute)
Z223.1, and NFPA (National File Protection Association)
54 TIA-54-84-1. In Cana&t, installation must be in accordance
with the CANI-BI49

Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate (see Tables 2A
and 2B). On 3-phase units, voltages between phases must be
bahmced within 2% and the currant within 10%. Use the formula shown in the legend for Tables 2A and 2B, Note 2 to determine the percent of voltage imbalance. Operation on improper
line voltage or excessive phase imbalance constitutes abuse and
may cause dmnage to electrictd components.
Such operation
would invali&tte any applicable Carrier wammty.
Unit cabinet must have tin uninterrupted, unbroken electrical ground to minimize the possibility of persomd injury if
an electrical fault should occm: This ground may consist of
electrical wire connected to unit ground lug in control comptu-tment, or conduit approved for electrical ground when
insttdled in accordance
with NEC (National Electrical
Code), ANSI/NFPA,
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.

If the new MCA does not exceed the published MOCP, then MOCP would not change.
The MOOP in this example is 35 amps, the MCA New is below 35, therefore the MOCP
is acceptable. If "MCA New" is larger than the published MOOP, raise the MOCP to the

Damper Movement -- Damper movement trom full open to
full closed (or vice versa) takes 2112minutes.
Thermostats -- The EconoMiSer IV control works with conventiomd thermostats that have a YI (cool stage 1), Y2 (cool
stage 2), Wl (heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMiSer IV control does not support space temperature
sensors. Connections are made at the thermostat termimd connection board located in the main control box.
Exhaust Set Point Adjustment
-- The exhaust set point will
determine when the exhaust fan runs based on dmnper position
(if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer
See Fig. 33. The set point represents the damper position above
which the exhaust fans will be turned on. When there is a call
for exhaust, the EconoMiSer IV controller provides a 45 _+15
second delay before exhaust fan activation to allow the dampers to open. This delay _fllows file damper to reach the appropriate position to avoid unnecessaly fan overload.
Occupancy Control -- The facto U default configuration for
the EconoMi$er IV control is occupied mode. Occupied status
is provided by the black jumper flom terminal TR to terminal
N. When unoccupied mode is desired, inst_dl a field-supplied
timeclock function in place of the jumper between TR and N.
See Fig. 27. When the timeclock contacts are closed, the
EconoMi$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.
Minimum Position Control -- There is a minimum damper
position potentiometer on the EconoMiSer [V controllel: See
Fig. 33. The minimum damper position maintains the minimum airflow into the building during the occupied period.
When using demand ventihttion, the minimum dmnper 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

cupied ventilation

Demand Controlled Ventilation (DCV) -- When using the
EconoMiSer IV for demand controlled ventilation, them are
some equipment selection criteria which should be considered.
When selecting the heat capacity and cool capacity of the
equipment, the maximum ventilation rote must be evaluated for
design conditions. The maximum damper position must be calculated to provide the desired fresh ail:
Typically the maximum ventilation rate will be about 5 to
10% morn than the typical chn required per person, using normid outside air design criteria.
ventilation control is not being used, the
potentiometer should be used to set the ocposition. The maximum demand ventilation
turned fully clockwise.
Adjust the minimum position potentiometer
to allow the
minimum mnount of outdoor aik 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
following procedure:

perform
1. Calculate the appropriate mixed air temperature
following formula:
OA
RA
(Tox I--F6_) +(TRx 1-Tff6-)=TM
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-anticipato U 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 roaches 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, fil.'stdetermine the damper voltage output for minimum or base ventilation. Base ventilation is the
ventilation required to remove contmninants 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.
the
using the
To = Outdoor-Air Temperature
OA = Percent of Outdoor Air
TR = Return-Air Temperature

As an example, if local codes require 10% outdoor

CarefiJlly adjust the minimum position potentiometer
until the measured supply air temperature matches the
calculated value.

Once base ventilation has been determined, set the minimum damper position potentiometer to the correct position.
The same equation can be used to deterlnine 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. 38
to determine the maximum setting of the CO2 sensol: For example, a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 38 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

Remote control of the EconoMi$er IV damper is desirable
when requiring additiomd temporm-y ventilation. If a
field-supplied remote potentiometer (Honeywell part number
$963B1128) is wired to the EconoMi$er IV controllek the
minimum position of the damper can be controlled from a mmote location.
To control the minimum damper position remotely, remove
the factory-installed jumper on the P and PI terminals on the
EconoMi$er IV controllel: Wire the field-supplied potentiometer to the P and PI terminals on the EconoMi$er IV controller.

*Motor drive range: 875 to 1192 rpm. All other rpms require a fieldsupplied drive.
GENERAL NOTES FOR FAN PERFORMANCE
1. Values include losses for filters, unit casing, and wet coils. See
Table 9 for FlOP static pressure information.
2. Performance data is based on clean filters and a wet coil.
3. Extensive motor and electrical testing on these units ensures
that the full range of the motor can be utilized with confidence.
Using the fan motors up to the wattage ratings shown will not
result in nuisance tripping or premature motor failure. Unit
DATA TABLES
warranty will not be affected. See Evaporator-Fan Motor Performance data in Table 8 on page 29 for additional information.
4. Use of a field-supplied motor may affect wire sizing. Contact
your Carrier representative for details.
5. Interpolation is permissible. Do not extrapolate.

OFF delay is 45 seconds. The Integrated Gas Unit Controller
(IGC) modifies this value when abnormal limit switch cycles
occm: 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 is observed, the
evaporator-fan ON/OFF delay has been modified.
If the limit switch trips at the stm-t 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.

the zone themlostat.
When flee cooling is available, the
outdoor-air damper is modulated by the EconoMiSer IV control
to provide a 50 to 55 F supply-air temperature into the zone. As
the supply-air tempemtme fluctuates above 55 or below 50 IF.
the dampel_ will be modulated (open or close) to bring the supply-air temperature back within the set point limits.
The PremierLink control will use the following information

COOLING.
UNITS WITH ECONOMISER2,
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 42.
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 dalnper is positioned through the use of a Proportional Integral (PlD) control
process to provide a calculated supply-air temperature into the
zone. The supply air will maintain the space temperature between the heating and cooling set points as indicated in Fig. 43.

The PremierLink
control will integrate the compressol:s
stages with the economizer based on simihu logic as the three
routines listed in the previous section. The SASP will float up
and down based on the error reduction calculations that comptue space temperature and space set point.
When outside-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.
