improvement. Consult with the sales agency or manufacturer for details.
The seriousness of safety precautions is classified by the following
indications:
WARNING This symbol indicates the possibility of death or serious injury.
CAUTION This symbol indicates the possibility of injury or damage to property.
WARNING
- Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock fire, and may void the warranty.
- Use the manufacturer’s specified and supplied parts only. 3) Install in a
strong and firm location which is able to withstand the unit’s weight. If the
strength is
insufficient or installation is not properly done, the units can fall and cause injury. 4) For electrical work, follow all local and National electrical codes and these installation instructions.
An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or a defect found in electrical work, it may cause electrical shock or fire. 5) Use the specified cable, connect tightly and clamp the cable so that no external force will be acted on the terminal. If connection is loose, it may cause excessive heat build up. 6) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause heat build up at connection point of terminal, fire or electrical shock. 7) When carrying out piping connection, take care not to let air substances other than the specified refrigerant go into refrigeration circuit. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury. 8) Do not modify the length of the power supply cord or use an extension cord, and do not share the single outlet with other electrical appliances. Otherwise, it may cause fire or electrical shock.
CAUTION - This equipment must be properly grounded and installed with and ground leakage current breaker, otherwise it may cause electrical shock.
- Do not install the unit in place where leakage of flammable gas may occur. If gas leaks and accumulates near or surroundings the unit, it may cause fire.

OPERATING INSTRUCTIONS
Air conditioners are designed to provide comfort cooling at outside
temperatures above 65°F (18°C) but less than 109°F (43°C). Operating the air
conditioner outside of this temperature range may cause unit failure and will
void the warranty. If you have need for cooling at lower outdoor temperatures
a “low ambient control” can be field installed. Contact your local contractor
or call the factory.
TO OPERATE: NOTE: The thermostat operation may vary by type and model used.
Please consult the operating manual that was provided with the thermostat. The
instructions below are generalized for most standard thermostat models.
1. Set the switch on your wall thermostat to the cool’ position. 2\. Set the desired temperature (between 63-86°F or 17-30°C) you want to maintain by moving the temperature setting on your thermostat. If the room is warmer than the setting, the unit will turn on and begin to blow cool air after a few minutes. A warm, humid room or building may take several hours of continuous operation to cool to the thermostat set point the first time. Once the set temperature is reached the unit will cycle on and off. 3\. Set theFan’ switch on the thermostat to auto’ if you want the fan to run only when cooling is needed or toon’ if you want continuous air
circulation. The on’ setting of the fan generally provides better temperature control by eliminating stagnant air. NOTE: A properly installed and sized unit will not cycle more than 10 times per hour. If you notice more frequent starts call your service contractor. 4\. For energy conservation reasons, you may want to set your thermostat at a higher temperature when you are away. Do not raise the temperature setting by more than 5 degrees. Changing the temperature by more than 5 degrees or shutting the unitoff’ can actually cost more than leaving the setting at a
constant temperature.
IMPORTANT
Wait at least 3 minutes after turning your air conditioner off before trying
to restart it. This gives the unit the time needed to stabilize before
restarting. Failure to do so may cause unit damage and failure.
MAINTENANCE: Only simple periodic maintenance is required: 1. Change or clean
the indoor unit air filter
monthly or more frequently if unusual conditions are encountered. If you have
a disposable type, throw the old one away and install a fresh one of the same
size and type. If your unit has a washable type then vacuum and wash with soap
and water. Flush thoroughly and dry before re-installing. 2. Keep the coil in
the outdoor unit clean. Periodically flush the coil thoroughly with a garden
hose. Clean away all foreign materials such as dust, leaves, grass clippings,
papers, etc.
WARNING
Turn the power off first! Serious injury or death may result if water spray is
directed at live electrical connections or power sources.
IMPORTANT!
Alterations and replacement parts: Altering the product or replacing parts
with non-authorized parts will void the factory Warranty and may result in
adverse operational performance and/or a possible hazardous safety condition
to service personnel and occupants. If you are in doubt as to how to service
this unit or where to find factory replacement parts, call Heat Controller at
517-787-2100 for assistance.

GENERAL PRODUCT INFORMATION
UNPACKING AND INSPECTION: The condensing unit is shipped completely assembled
and in it’s own package. All goods are inspected at the factory and released
to the freight company in good condition. When received at the site, a visual
inspection of all packages should be made immediately. Any evidence of rough
handling or apparent damage should be noted on the delivery receipt and the
material inspected in the presence of the carrier’s representative. If damage
is found a claim should be immediately filed with the freight company.
COOLING OPERATION
TEMPERATURE LIMITS: Heat Controller Condensing units are designed to operate
in cooling at outside temperatures between 65°F (18°C) and 109°F (43°C). If
the condensing unit will be used to cool at temperatures below 65°F (18°C), a
low ambient control must be field installed. Operation below 65°F (18°C)
without low ambient control will void the warranty.
INDOOR UNIT USE
AND SYSTEM EFFICIENCY: Heat Controller condensing units are designed to be
compatible with most major brands of domestic evaporator coils/air handlers.
Imported ductless air handlers may be used but often do not include an
expansion device. A properly sized thermostatic expansion valve is
recommended. Consult AHRI’s directory of certified products for indoor
matches.
THERMOSTAT AND INDOOR FAN TIME DELAY: All indoor units should include a fan
time delay. This may be accomplished by using a digital wall thermostat or
installation of a different fan time delay designed to work with your specific
furnace/ air handler. As follow:
Most brands of electronic thermostats include a fan delay. Properly specified
thermostats are the responsibility of the installer. Proper temperature
control and unit operation depends on proper thermostat selection and
location. Refer to the thermostat manufacturer’s installation instructions for
specified recommendations. Good practice is to avoid outside walls, locations
where the sun may shine directly on the thermostat, and locations where the
air from supply registers or unit outlets blow on the thermostat. Also avoid
locations where the thermostat could be jarred by a closing door or high
traffic area.
WARNING: An in-line filter drier is required when the unit is installed. The
filter drier is not provided by the factory, therefore a locally purchased
filter drier must be used to remove any particulates or moisture that may be
present in the system. Installations without an in-line filter drier may void
the warranty.

OUTDOOR UNIT INSTALLATION
UNIT LOCATION AND MOUNTING: Choose a location that places the condensing unit
as close to the indoor unit as possible. The maximum unit separation and
vertical lift (compressor above evaporator) must be taken into account [See
Fig 1]. Do not exceed allowable pipe lengths. Fig. 1
*Minimum pipe length must not be less that 15 feet. ** “P” trap risers every 10 ft. when outdoor unit is installed above indoor unit. NOTE: Oil traps must be installed every 10ft. when the outdoor unit is installed above the indoor unit.
Install the outdoor unit on a rigid surface, able to withstand the unit’s
weight, such as a concrete slab.
If the installation location allows the unit to be exposed to strong winds
(such as sea side applications), ensure that the unit has a barrier from the
wind [See Fig. 2]. This will assist with the proper operation of the fan by
obstructing strong gusts of wind from entering the unit’s cabinet.
An awning can be built over the outdoor unit to prevent direct sunlight or
rain exposure or snowfall. Ensure that the awning is at least 2 ft. above the
top of the unit’s housing.
During heating and defrost modes, the condensate should be properly drained
away from the unit.
Insure free flow of air into and out of the unit. Inlets/outlets should stay
clear of obstructions such as walls and shrubs. Minimum clearances must be
adhered to [See Fig. 4 & 5 on page 7].
Do not locate two or more units in a way that will block air flow or in a way
that hot air from one unit will blow into a nearby unit [See Fig. 3].
Avoid areas where water, snow, or ice may fall from a roof onto the unit. In
climates where snow is a consideration, locate the unit away from areas prone
to drifting. Ensure the location of the unit will not be subject to snow
drifts, heavy accumulation of snow or leaves or other seasonal debris. If
unavoidable, provide the awning for the unit.

UNIT WIRING
ELECTRICAL WIRING AND SUPPLY VOLTAGE: All electrical wiring must be done
according to NEC and local codes. Nameplate data indicates the operating
voltage, phase, ampacity, maximum over current protection, and minimum
voltage.
The contractor is to provide an individual branch circuit for over current
protection for the unit as required by code. Run power supply wiring through a
weatherproof disconnect box and conduit to the unit connection. Disconnects
are required to be within sight and easy reach of the unit (usually within 3
feet).
Check the unit wiring diagram for the number of conductors required. Route
neatly and protect from sharp edges and damage.
Inadequate wiring and/or improper electrical supply will likely result in
failure of the compressor and other electrical components and voids the
warranty.
NOTE: The supply voltage must be consistent with the rated voltage of the air
conditioner, not to exceed +/- 10%. Ensure the unit is properly grounded.
Outdoor unit wiring connection
1. Remove the electrical control cover from the outdoor unit.
2. Connect the cables to the terminals as identified with their respective
designated terminal spaces on the terminal block of indoor and outdoor units.
600V THHN 14 AWG/4 conductor unshielded stranded copper cable is recommended,
however NEC/local codes prevail.
3. To prevent the entrance of water into outdoor unit, form a loop in the
cable [See Fig. 6].
4. Insulate any unused conductors with PCV/ Electrical tape, so that they do
not touch any other exposed electrical or metal parts.
CAUTION
Incorrect wiring connections may cause electrical parts to malfunction. All
wiring must comply with local and national electrical codes and be installed
by qualified and skilled electricians.

REFRIGERANT PIPING
The length of refrigerant lines and the number of bends determine the pressure
drop which affects capacity and efficiency of the system and oil return to the
compressor. The outdoor unit connections are braze type. Tube size should
always be the same diameter as the connections provided at the service valves.
Up sizing of lines can result in inadequate oil return to the compressor and
excessive refrigerant charge and will void the warranty [See Table 1].
*Minimum pipe length must not be less that 15 feet. ** “P” trap risers every 10 ft. when outdoor unit is installed above indoor unit.
Choose a location that places the condensing unit as close to the indoor unit
as possible. The maximum separation is dependent on model. Use only clean
refrigeration grade tubing. Avoid piping on wet or rainy days. Always keep the
tube ends capped until you are ready to make the final connections. Remove
burrs from cut ends of tubing. Use tube benders to avoid kinking.
Insulate the suction line with Armaflex or equivalent with a wall thickness of
at least 3/8″. Support the tubing adequately to avoid sags that can trap oil.
Isolate the tubing so as not to transmit noise to the building structure.
Avoid sharp edges that could cut the tubes. Maximum vertical lift (compressor
above evaporator) is dependent on model. Trap risers with a `P’ trap every 10
feet.
WARNING
It is illegal to discharge refrigerant into the atmosphere. Use proper
reclaiming methods and equipment when working on the refrigerant containing
parts of the unit. Service should be performed by a QUALIFIED service agency
and certified technicians.
LEAk TEST,
EVACUATION
& RELEASE OF
REFRIGERANT
The condensing unit is supplied with R-410a charge sufficient for most
matching evaporator units. Charge must be added for interconnecting tubing.
The unit’s service valves are shipped in the closed position and should not be
opened until final connections and evacuation are completed.
The recommended procedure for leak test, evacuation, and release of
refrigerant is outlined below: 1. Complete the final piping connections to the
indoor and outdoor units using high temperature brazing alloy. 2. Connect a
charging manifold to the service ports provided at the service valves. 3.
Pressurize the lines and evaporator with nitrogen and leak check all
connections with soap bubbles. Repair as necessary any faulty joints. If
brazing is required be sure to RELEASE THE NITROGEN FIRST. Re-test as needed.
4. Connect a vacuum pump to the manifold center connection, start the pump and
open the manifold valves. 5. Evacuate to 500 microns or less for a minimum of
30 minutes. Close the manifold valves and shut off the pump. Note the vacuum
reading and wait 15 minutes. Take a new vacuum reading. A reading of 800
microns or higher indicates the presence of moisture or a leak. 6. Repair as
necessary and repeat steps 3, 4 & 5. 7. Confirm that manifold valves are
closed and disconnect the vacuum pump. 8. Remove the caps from the services
valves. Open the valves to the fully `back-seat’ position. Replace service
valve caps and tighten.

INITIAL START-UP & CHECkS
Operation of the unit is automatic and will provide cooling depending on the
setting of the thermostat.
IMPORTANT! All panels must be installed, main power turned on and the
thermostat properly connected before operating the unit.
1. System check – set thermostat system switch to “Off” position and fan
switch to “Auto” position. Turn the power supply breaker on.
2. Set the fan switch to “On,” blower should operate.
3. Return the fan switch to “Auto”. Blower should shut off. Set the system
switch to “Cool” and lower thermostat set point to coldest setting. The
compressor, condenser fan, and evaporator blower should all come on. Cool air
will be supplied after a couple of minutes of run time.
4. Proceed to the “FIELD CHARGING” section of these instructions.
FIELD CHARGING
Unit performance, efficiency, and life depends, to a large extent, on a proper
system charge. Time spent on getting the charge right at start-up will payoff
in the long run. Operating conditions such as voltage, air flow, evaporator
coil size, and indoor and outdoor temperature and humidity all have an effect
on the system pressures and superheat conditions.
Charge must be added for the interconnecting tubing. Use of piston-style
metering device is typical. Where TXV’s are used, a 15% bleedtype is required.
Use of Non-bleed TXV’s will void warranty. These units should be critically
charged to ensure proper performance. Some systems may require additional
charging of refrigerant, depending on line set lengths.
FINAL INSPECTION
Do a final visual inspection of the entire installation and complete any final
details and clean up. Review Unit Operation with the homeowner/user. The
pressure/temperature chart can be used as a reference to ensure performance.
