3.0 DUCTWORK
NOTE
On ductwork exposed to outside air conditioning space, use at least 2” of
insulation and a vapor barrier. Flexible joint may be used to reduce noise.
These units are adaptable to downflow use as well as rear supply and return
air duct openings. To convert to downflow, use the following steps:
1. Remove the duct covers found in the bottom return and supply air duct
openings. There are four (4) screws securing each duct cover (save theses
to use in step 2).
2. Install the duct cover (removed in step one) to the rear supply and return
air openings. Secure with the four (4) screws used in steps one.
3. Seal duct covers with silicone caulk.
4.0 CONDENSATE DRAIN CONNECTION
1. Use female NPT threaded fitting for outside connection and make sure that
drain holes are not blocked.
2. Insulation may be needed for drain line to prevent sweating.
3. Drain pan has two drain connections on each side to provide flexibility of
connection and drainage. Make sure proper pitch and plugging if second
connection is not used.
4. Use a sealing compound on male pipe threads. Install the condensate
drain line (NPT) to spill into an open drain.
A closed return duct system shall be used. This shall not preclude use of
economizers or ventilation air intake. Flexible joints may be used in the
supply and return duct work to minimize the transmission of noise.
When fastening duct work to the side duct flanges on the unit, insert the
screws through the duct flanges only. DO NOT insert the screws through
the casing. Outdoor duct work must be insulation and waterproofed.
CAUTION
NOTE
Be sure to note supply and return openings. Refer to Fig. 3 and 4 for
information concerning rear and bottom supply and return air duct
openings.
Consult local codes for special requirements.
To provide extra protection from water damage, install an additional drain pan,
provided by installer, under the entire unit with a separate drain line. Manufac-
turer will not be responsible for any damages due to the failure to follow these
requirements.
4.1 INSTALL DRAIN PIPE
Duckwork should be made and sized by installer and in accordance with Air
Manual from Conditioning Contractors of America and local codes.

9
6.0 ELECTRICAL WIRING
Field wiring must comply with the National Electric Code (NEC) or Canadian
Electrical Code (CEC) and any applicable local ordinance.
WARNING
Disconnect all power to unit before installing or servicing. More than one
disconnect switch may be required to de-energize the equipment. Hazard-
ous voltage can cause severe personal injury or death.
Units are shipped without a filter or filter racks. It is the responsibility of the
installer to secure a filter in the return air ductwork or install a filter/frame Kit.
Filter must always be used and must be kept clean. When filter become dirt
laden, insufficient air will be delivered by the blower, decreasing your units
efficiency and increasing operation costs and wear-and tear on the unit and
controls.
Filters should be checked monthly; this is especially important since this unit is
used for both heating and cooling.

•Make sure, after installation, separation of control wiring and power wiring
has been maintained.
6.2 GROUNDING
WARNING
The unit must be permanently grounded. Failure to do so can result in
electrical shock causing personal injury or death.
• Grounding may be accomplished by grounding metal conduit when installed in
accordance with electrical codes to the unit cabinet.
•Grounding may also be accomplished by attaching ground wire(s) to ground
lug(s) provided in the unit wiring compartment.
6.1 POWER WIRING
1. Proper electrical power should be available at unit. Voltage tolerance should not
be over 10% from rating voltage.
2. If any of the wire must be replaced, replacement wire must be the same type
as shown in nameplate, wiring diagram and electrical data sheet.
3. Install a branch circuit disconnect of adequate size to handle starting current,
located within sight of, and readily accessible to the unit.
4. ELECTRIC HEATER - If the Electric Heater is installed, unit may be equipped
with 25~50A. circuit breakers or fuse. These breaker(s) protect the internal wiring
in the event of a short circuit and serve as a disconnect. Circuit breakers installed
within the unit do not provide over-current protection of the supply wiring and
therefore may be sized larger than the branch circuit protection.
•Supply circuit power wiring must be 221 °F minimum copper conductors only.
See Electrical Data in this section for ampacity, wire size and circuit protector
requirements. Supply circuit protective devices may be either fuses or “HACR”
type circuit breakers.
•An 1-3/8” knockouts inside cabinet is provided for connection of power wiring to
electric heater.
• Power wiring is connected to the power terminal block in unit electric cabinet.
See Electrical Heater Installation Instruction for details.
6.3 CONTROL WIRING
IMPORTANT: Class 2 low voltage control wiring SHOULD NOT be run in
conduit with main power wiring and must be separated from power wiring,
unless class 1 wire of proper voltage rating is used.
•Low voltage control wiring should be 18 AWG color-coded. For lengths
longer than 50 ft, 16 AWG wire should be used.
•Two 7/8” holes can be used for control wires going into the unit, one on left
side and one at the bottom.
Thermostat should be mounted on an inside wall about 58” from floor and
will not be affected by unconditioned air, sun and/or heat exposure. Follow
the instruction carefully because there are many wiring requirements.
See Fig. 6-1 ~ 2, Table 7-1 ~ 4

* The above airflow data for reference only.
●The air distribution system has the greatest effect on airflow. The duct system is totally controlled by the contractor. For this
reason, the contractor should use only industry-recognized procedures.
●Heat pump systems require a specified airflow. Each ton of cooling requires between 350 and 450 cubic feet of air per minute
(CFM), or 400 CFM nominally.
●Duct design and construction should be carefully done. System performance can be lowered dramatically through bad
planning or workmanship.
●Air supply diffusers must be selected and located carefully. They must be sized and positoined to deliver treated air along the
perimerter of the space. If they are too small for their intended airflow, they become noisy. If they are not located properly, they
noise.
●The installers should balance the air distribution system to ensure proper quiet airflow to all rooms in the home. This ensures a
comfortable living space.
●An air velocity meter or airflow hood can give a reading of system CFM.
●When installation, installer should select the air speed according to the actual setting static pressure. Please refer to the Table
7-1, 7-2 AIRFLOW PERFORMANCE DATA.

8.0 SYSTEM OPERATION
Refrigerant migration during the off cycle can result in a noisy start up. Add
a crankcase heater to minimize refrigeration migration, and to help eliminate
any start up noise or bearing “wash out”.
All heaters are located on the lower half of the compressor shell. Its purpose
is to drive refrigerant from the compressor shell during long off cycles, thus
preventing damage to the compressor during start-up.
At initial start-up or after extended shutdown periods, make sure the heater
is energized for at least 12 hours before the compressor is started.
(Disconnect switch on and wall thermostat off.)
The crankcase heater start-up conditions:
If the outdoor ambient temp. is ＜37.4°F and the compressor stopped for
more than three hours or the unit powered on once more, the crank heater
will be on.
Crankcase heater shut-down conditions:
If the outdoor ambient temp. is ＞44.6°F or the compressor start running ,the
crank heater will be off.
8.1 COMPRESSOR CRANKCASE HEATER(Optional)
8.3 DEFROST MODE* (For HP system only)
When the sensor T3 (Condenser pipe temperature) &T4 (Outdoor ambient
temperature) was checked open-circuit, the compressor, outdoor fan motor
and 4-way valve will be off.
Discharge temperature protection
When discharge temp. is ＞275°F, the compressor will be off,
When discharge temp. is ＜194°F, the compressor will start running.
High pressure protection
When high pressure is ＞638PSIG, the compressor and the outdoor fan motor
will stop running.
When high pressure is ＜464PSIG, the compressor and the outdoor fan motor
will start running(3 minutes delay necessary ).
Low pressure protection
When low pressure is ＜21PSIG, the compressor and the outdoor fan motor
will stop running.
When low pressure is ＞44PSIG, the compressor and the outdoor fan motor
will start running(3 minutes delay necessary ).
In stand-by status, if low pressure protection was checked out, the compressor
would not start running.
If protection cycles occur four times within 30 mins, the system must power on
once more.
T4 function:
When T4 is < 5 °F, the compressor will stop. If the electrical heater kit is
installed
in the indoor unit, the outdoor unit will send the operation signal to the indoor
unit.
When T4 is > 10.4 °F, the compressor will restart.
Defrosting condition:
When JUMP switch is set to “1”, the defrost mode will start if one of following
conditions is satisfied:
1. Compressor keeps running, when T4 is > 28.4 °F and T3 is < 32 °F and last
for 40 minutes;
2. Compressor keeps running, when T4 is < 28.4 °F and T3 is < 32 °F and last
for 50 minutes.
8.2 Protection (For HP system only)
* When defrosting Actions, if the electrical heater kit is installed in the indoor unit, the outdoor unit
would deliver the Aux. heater operation signal to the indoor unit.
