GENERAL INSTRUCTIONS
IMPORTANT
The equipment covered in this manual is to be installed by trained, experienced service and installation technicians. All duct work, supply and return ducts, must be properly sized for the design air flow requirement of the equipment. ACCA is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage.
SHIPPING DAMAGE
Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.
GENERAL
The refrigerant system is completely assembled and charged. All internal wiring is complete.
The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return ducts.
These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.
These instructions and any instructions packaged with any separate equipment required to make up the entire heat pump system should be carefully read before beginning the installation. Note particularly “Starting
Procedure” and any tags and/or labels attached to the equipment.
While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made.
FIELD INSTALLED HEATER PACKAGES
(OPTIONAL)
These packaged air conditions are manufactured without supplementary electric heaters. Supplementary heaters are available for simple, fast field installation.
A separate power circuit is required for the supplementary heaters.
IMPORTANT : Refer to Table 1 when designing duct work for maximum available static pressure with heater installed.
Refer to data shown in Table 3 and 4 for proper application information on all available heater combinations and what units they can be used with. It also shows the applicable circuit ampacities, fuse size, and wire size for each heater combination.

INSTALLATION
LOCATION
GENERAL
The unit must be located outside, or in a well ventilated area. It must not be in the space being heated or cooled.
A sound absorbing material should be considered if the unit is to be installed in such a position or location that might cause transmission of sound or vibration to the living area or adjacent buildings.
SLAB MOUNTING
In areas where winter temperatures DO NOT go below
32° F for periods over twelve hours, the unit may be slab mounted at grade level. When installing unit at grade level, install on a concrete slab at least four inches above finished grade level. Slab should have a slope tolerance away from the building structure of at lease 1/4 inch per foot, while being level from side to side. Place slab in a location where runoff water from higher ground will not collect around unit. See
Figure 2.
A minimum of 18 inches should be provided between the coil inlet and any building surfaces. Provide at least four feet between coil outlet and any building wall, fences or other vertical structures. Provide a minimum of three feet clearance on the service access side of the unit. See Figure 3.
ROOF MOUNTING
When a unit is installed in areas where low ambient temperatures or strong winter winds exist, it should be placed for prevailing winter winds are not in direct line with the outdoor coil. If this is not possible, a wind barrier should be constructed. Place barrier 24 inches from the coil inlet side of the unit and in the direction of prevailing winds. Size barrier at least the same height and width as the unit. This may be necessary on ground level installations, also. See Figure 4.
WINTER INSTALLATION BELOW 32°F
In areas where winter conditions go below 32°F for extended periods, the unit must be elevated above the mounting surface to prevent snowfall or ice accumulation from interfering with the operation of the unit. A minimum of twelve inch elevation is recommended, while greater elevation may be required for areas of high snow accumulation. Poured concrete, steel framework, brick, cement block, etc., can be utilized to construct a suitable raised mounting platform. See Figure 5.
TYPICAL INSTALLATIONS
1.
ROOF MOUNTED – The unit is mounted on a sturdy base on the roof of the building. Return air to the unit is brought through a single return grille
(grilles with built-in filters are best since they enable easy access for filter changing). Return air ducts are attached to the lower section of the front panel. Supply air is brought from the unit to attic duct work or to a furred down hall. Supply air duct is attached to the top of the front panel.
CAUTION: All outdoor duct work must be thoroughly insulated and weatherproofed. All attic duct work must be thoroughly insulated.
Two inch thick insulation with suitable vapor barrier is recommended for both outdoor and attic runs.
In roof top installation, as in all installations, the air conditioner must be level from side to side.
However, the unit should have a pitch along the length to assure complete external drainage of precipitation and of defrost condensate. See Figures
6 and 7, and Tables 6 and 7.
2.
CRAWL SPACE – Duct work installed in crawl space must be well insulated and provided with a vapor barrier. In addition, the crawl space must be thoroughly ventilated and provided with a good vapor barrier as a ground cover. It is most desirable to install the unit will be outdoors rather than inside the crawl space, so that it will be readily accessible for service.
3.
SLAB MOUNTED AT GROUND LEVEL – This type installation is ideal for homes with a slab floor construction where a roof mounted unit is not desired. The supply and return duct work can be run through a furred closet space.
4.
THROUGH THE WALL – This type installation requires a suitable framework to be fabricated capable of withstanding the unit weight. Normally the unit will be insulated so as to minimize supply and return duct work.

OTHER INSTALLATIONS – Many other installations are possible with the packaged air conditioner. No matter what the installation, always consider the following facts:
A. Insure that the discharge air is not obstructed in any way so as to cause operation difficulties.
B. The indoor coil drain pan is equipped with a coupling that must be piped through a condensate drain trap to a suitable drain.
C. Always mount the unit is such a position that it may be easily reached for servicing and maintenance.
D. Insure that the unit is clear so that proper air flow over the outdoor coil will be maintained.
If this unit is operated in cooling below a 65° outdoor ambient temperature, the installation of low ambient controls (CMA-6) to unit is required.
CONDENSATE DRAIN TRAP
It is very important to provide a trap in the condensate drain line to allow a positive liquid seal in the line and assure correct drainage from the coil condensate pan.
Install condensate drain trap shown in Figure 8. Use drain connection size or larger. Do not operate unit without trap. Unit must be level or slightly inclined toward drain. With a trap installed on a unit located in an unconditioned area, water in the trap may freeze. It is recommended that the trap material be of a type that will allow for expansion of water when it freezes.
AIR FILTERS
Air filters for the return air side of the system are not provided as part of these models, and must be field supplied and installed as part of the final installation.
Prior thought should be given to return air location and placement of the air filter(s). The air filter(s) must be of adequate size and readily accessible to the operator of the equipment. Filters must be adequate in size and properly maintained for proper operation. If this is not done, excessive energy use, poor performance, and multiple service problems will result. It is impossible to
oversize air filters. Generous sizing will result in cleaner air and coils as well as lower operating costs and extend the time between required changes. Table 8 shows minimum filter areas and recommended filter sizes. Actual filter sizes can vary with the installation due to single or multiple returns utilizing a filter/grille arrangement or being placed immediately ahead of the indoor coil face in the return air duct.

WIRING – MAIN POWER
Refer to the unit rating plate for wire sizing information and maximum fuse size. Each outdoor unit is marked with a “Minimum Circuit Ampacity”. This means that the field wiring used must be sized to carry that amount of current. If field installed heaters are added to the basic unit, a second separate power supply circuit will be required. The heater rating plate located adjacent to the basic unit rating plate will show the appropriate circuit ampacity fuse size, etc. (Also see “Electrical
Specifications” on pages 3, 4 and 5.) All models are
suitable for connection with copper wire only. These instructions must be adhered to. Refer to the National
Electrical Code for complete current carrying capacity data on the various insulation grades of wiring material.
The electrical specifications list fuse and wire sizes
(75°F copper) for all models including the most commonly used heater sizes.
The unit rating plate lists a “Maximum Time Delay
Fuse” or “HACR” type circuit breaker that is to be used with the equipment. The correct size must be used for proper circuit protection and also to assure that there will be no nuisance tripping due to the momentary high starting current of the compressor.

TRANSFORMER TAPS
230/208V, 1 phase and 3 phase equipment employ dual primary voltage transformers. All equipment leaves the factory wired on 240V tap. For 208V operation, reconnect from 240V to 208V tap. The acceptable operating voltage range for the 240 and 208V taps are:
TAP
240
208
RANGE
253 – 216
220 – 187
NOTE: The voltage should be measured at the field power connection point in the unit and while the unit is operating at full load (maximum amperage operating condition).
WIRING – 24V LOW VOLTAGE CONTROL
CIRCUIT
Five (5) wires should be run from thermostat subbase to the 24V terminal board in the unit. A five conductor,
18 gauge copper, color-coded thermostat cable is recommended. The connection points are shown in
Figure 9.

START UP AND OPERATION
THREE PHASE SCROLL COMPRESSOR
START UP INFORMATION
Scroll compressors, like several other types of compressors, will only compress in one rotational direction. Direction of rotation is not an issue with single phase compressors since they will always start and run in the proper direction.
However, three phase compressors will rotate in either direction depending upon phasing of the power. Since there is a 50-50 chance of connecting power in such a way as to cause rotation in the reverse direction, verification of proper rotation must be made.
Verification of proper rotation direction is made by observing that suction pressure drops and discharge pressure rises when the compressor is energized.
Reverse rotation also results in an elevated sound level over that with correct rotation, as well as, substantially reduced current draw compared to tabulated values.
Verification of proper rotation must be made at the
time the equipment is put into service. If improper rotation is corrected at this time there will be no negative impact on the durability of the compressor.
However, reverse operation for over one hour may have a negative impact on the bearing due to oil pump out.
NOTE: If compressor is allowed to run in reverse rotation for several minutes the compressor’s internal protector will trip.
All three phase ZR*3 compressors are wired identically internally. As a result, once the correct phasing is determined for a specific system or installation, connecting properly phased power leads to the same
Fusite terminals should maintain proper rotation direction.
The direction of rotation of the motor may be changed by reversing any two line connections to the unit.
SEQUENCE OF OPERATION
COOLING – Circuit R-Y makes at thermostat pulling in compressor contactor starting the compressor and outdoor motor. The G (indoor motor) circuit is automatically completed on any call for cooling operation, or can be energized by manual fan switch on subbase for constant air circulation.
HEATING – A circuit R-W1 is completed on each heating cycle energizing electric heat if so equipped.
START UP NOTES
For improved start up performance, wash the indoor coil with dishwasher detergent.
INDOOR BLOWER MOTOR
Some models feature a variable speed (ECM) motor providing high efficiency, low sound levels and soft start capabilities. The motor is self adjusting to provide the proper air flow rate at duct static pressures up to
0.50” WC without user adjustment or wiring changes.
On command from the wall thermostat the motor will start slowly and ramp up to full speed over a period of
10- 15 seconds.
When the thermostat is satisfied the blower will operate for approximately 1 minute, and then slow down and stop.
COMPRESSOR CONTROL MODULE
The compressor control is an anti-short cycle/lockout timer with high and low pressure switch monitoring and alarm output.
ADJUSTABLE DELAY-ON-MAKE AND BREAK
TIMER
On a call for compressor operation the delay-on-make period begins which will be 10% of the delay-on-break setting. When the delay-on-make is complete and the high pressure switch (and low pressure switch if employed) is closed, the compressor contactor is energized. Upon shutdown the delay-on-break timer starts and prevents restart until the delay-on-break and delay-on-make periods have expired.
HIGH PRESSURE SWITCH AND LOCKOUT
SEQUENCE (Standard Feature)
If the high pressure switch opens, the compressor contactor will de-energize immediately. The lockout timer will go into a soft lockout and stay in soft lockout until the high pressure switch closes and the delay-onmake time has expired. If the high pressure switch opens again in this same operating cycle the unit will go into manual lockout condition and the alarm circuit will energize. Recycling the wall thermostat resets the manual lockout.
Manual 2100-353
Page 17
LOW PRESSURE SWITCH, BYPASS, AND
LOCKOUT SEQUENCE
NOTE: The low pressure switch is an optional control and the bypass and lockout sequence are part of the standard compressor control module.
If the low pressure switch opens for more that 120 seconds, the compressor contactor will de-energize and go into a soft lockout. Regardless the state of the low pressure switch, the contactor will reenergize after the delay-on-make time delay has expired. If the low pressure switch remains open or opens again for longer than 120 seconds the unit will go into manual lockout condition and the alarm circuit will energize. Recycling the wall thermostat resets the manual lockout.
.
ALARM OUTPUT
Alarm terminal is output connection for applications where alarm signal is desired. This terminal is powered whenever compressor is locked out due to HPC or LPC sequences as described.
NOTE: Both high and low pressure switch controls are inherently automatic reset devices. The high pressure switch and low pressure switch cut out and cut in settings are fixed by specific air conditioner or heat pump unit model. The lockout features, both soft and manual, are a function of the Compressor Control Module.
ADJUSTMENTS
ADJUSTABLE DELAY-ON-MAKE AND
DELAY-ON-BREAK TIMER
The potentiometer is used to select Delay-on-Break time from 30 seconds to 5 minutes. Delay-on-Make (DOM) timing on power-up and after power interruptions is equal to 2 minutes plus 10% of Delay-on-Break (DOB) setting:
0.5 minute (30 seconds) DOB = 123 second DOM
1.0 minute (60 seconds) DOB = 126 second DOM
2.0 minute (120 seconds) DOB = 132 second DOM
3.0 minute (160 seconds) DOB = 138 second DOM
4.0 minute (240 seconds) DOB = 144 second DOM
5.0 minute (300 seconds) DOB = 150 second DOM

SERVICE AND TROUBLESHOOTING
SERVICE HINTS
1. Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces air flow through the system which shortens equipment service life as well as increasing operating costs.
2. Check all power fuses or circuit breakers to be sure that they are the correct rating.
3. Periodic cleaning of the outdoor coil to permit full and unrestricted airflow circulation is essential.
PRESSURE SERVICE PORTS
High and low pressure service ports are installed on all units so that the system operating pressures can be observed. Pressure tables can be found later in this manual covering all models on cooling cycle. It is imperative to match the correct pressure table to the unit by model number.
REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit rating plate. Optimum unit performance will occur with a refrigerant charge resulting in a suction line temperature (6” from compressor) as shown in
Table 11.

SUCTION AND DISCHARGE TUBE
BRAZING
Compliant Scroll compressors have copper plated steel suction and discharge tubes. These tubes are far more rugged and less prone to leaks than copper tubes used on other compressors. Due to different thermal properties of steel and copper, brazing procedures may have to be changed from those commonly used.
•
To disconnect: heat joint Areas 2 and 3 slowly and uniformly until braze material softens and the tube can be pulled out of suction fitting. (See Figure 10.)
•
To connect:
– Recommended brazing materials: silfos with minimum 5% silver or silver braze material with flux.
FIGURE 11
BRAZING DIAGRAM
– Reinsert tube into fitting.
– Heat tube uniformly in Area 1 moving slowly to
Area 2. When joint reaches brazing temperature, apply brazing material. (See
Figure 11)
– Heat joint uniformly around the circumference to flow braze material completely around the joint.
– Slowly move torch into Area 3 to draw braze material into joint. (See Figure 11.)
– Do not overheat joint.
