Determine the best location for mounting the indoor unit, it must be located a minimum of 4 ft (6 ft or more recomended) from the floor and no less than 6" from ceiling. Pay attention to the air circulation in the room, 9,000 & 12,000 Btuh units throw air 15ft, 18,000 & 24,000 Btuh units throw air 25ft, ensure no obstacles to airflow exist. Locate the indoor and outdoor units as close together as possible, maximum line set run and lift MUST NOT BE EXCEEDED.

J J Remove indoor and outdoor units from the carton/box, indoor unit carton contains, remote controt and batteries, ensure these are kept in a safe place during installation. Locate area to install indoor unit the unit should be located a minimum of 6 ft. from the floor and 6" from the ceiling. Choose an area where the watt is plumb and determine how to best to run the unit interconnects.
Prepare the evaporator for moundng by removing the mounting bracket from the rear of the indoor unit. Use a Phillips head screwdriver to remove the unit pipe strap. If the unit is a heat pump the defrost sensor also must be undone from its retainer. If mounting the unit on an outside wall measure from the edges of the unit to the center of the line set 90 ° bend to locate the the center of the wall penetration. Drill a 3" e hole through the wall.
_are unit fine set connections Rotate refrigerant line stubs gently to 90 ° (if mounting on an outside wall). For other line set configurations align the stubs as required. ieP: Use Duct tape to tape the Con-_ nsate hose (make sure it is below I the Line set stubs) and the defrost I sensor (heat pump only).
Install unit on mounting bracket Feed the line set stubs/condensate hose/ wiring connections through a o 3" hole in the walt. Position the evaporator so that the "key" slots on the back of the unit slide onto the tabs on top of the mounting bracket. Then push the lower portion of the evaporator against the bracket until it latches into the mounting bracket. indoor unit is now installed, it should be ptumb, level and flush with the wait.
Re_nt Line Set Pi in interconnectingline set between the outdoor unit and the indoor unit, must have both refrigerant lines insulated as the expansion device is located in the outdoor unit. Gently bend the tine set stubs from the indoor unit to the desired location. Using 2 x 10"/12" Crescent wrenches remove the flare nuts from the indoor unit tine stubs. The indoor unit is filled with a dry gas, check for retease of this to ensure that no leaks are present.
Evacuation Gauges can now be attached to the service ports - SERVICE PORTS HAVE A 5/16" CONNECTION TO GAUGES, which is different from the norm for R-22. You will need specific hoses or an adaptor for the 5/16" connection. Once the gauges are attached the line set can be leak checked using Nitrogen at 300 psig. Evacuate the unit and interconnect down to a minimum of 400-500 Microns, break vacuum with Nitrogen to further leak check.
Electrical Wifin_ installation Electrical Wiring should be done by a certified electrician in accordance with aft National ElectdcaICode (NEC) and local state!city building codes. ALL CONTROLS WIRING BETWEEN INDOOR AND OUTDOOR UNIT IS HIGH VOLTAGE MINIMUM 14 AWG WIRE MUST BE USED. Remove terminal covers from indoor unit and wire to the terminals, (small screwdriver required). Control wiring from the Control wiring at outdoor unit (cooling only).
If the system is a heat pump the defrost sensor must be connected from the indoor unit to the defrost sensor in the outdoor unit. Standard lead length is 25 ft, if a longer length is required then cut the lead and extend using thermostat wire. ote: use of colored wire (supplied with_ Illne set) and defrost sensor connected I (_eatpump only). .... The heat pump defrost sensor interconnect wire comes bundled up with the indoor units.
12) Condensate Hose: The unit is provided with approximately 18" of condensate hose connected. Hose connection is sized to accept a 3/4" OD or 5/8" ID clear plastic hose to then extend to building drain. There is approximately 6' of additional drain hose supplied with the (accessory) line set. With the evaporator and line set completely evacuated the system can now be opened to allow the refrigerant charge in the outdoor unit to be released into the line set.
Start the indoor unit, cooling mode is only allowed when the outside ambient temperature is above 60 ° F to prevent damage to the compressor. Unit has a 3 minute time delay before the compressor start up operation. ote: tf interconnect is less then 12_ eta small amount of refrigerant may I ed to be reclaimed to achieve the I oper charge for optimal operation.
Instrucdons: 1. Measure suction pressure and determine evaporator-refrigerant temperature on R410A scale of low-side gauge. 2. Measure suctionqine temperature on suction line of the unit. 3. Measure outdoor and indoor temperatures. 4. Determine from the table what the superheat should be for the indoor and outdoor temperatures. 5. Adjust charge if needed. Be sure unit is running at stabilized condition.

Features of Heating Operations proximately !5 ° F outdoor temperature e to a sensor located in the outdoor unit. portant: Heating operation will cease is product does not contain supplemenI tal electric heat, therefore other means of I heat need to used when this system ceas_,,_soperation at low outdoor ambients. _ei lee and erformaneee , The Heat Pumps absorb heat from the outdoor air and transfers it indoors to heat the indoor air.
Maintenance To clean the surface of the air conditioner: Use a soft and dry cloth to wipe the air conditioner off, or use a vacuum cleaner to clean it. , if the air conditioner is very dirty, use a damp soft cloth with a neutral household detergent to clean the surface of the unit. f"NNote: If the air filter screen is blocked_ by dust or dirt, the performance of cooling and heating will be affected, and the operation noise and power consumption will increased.
Basic Operation Characteristics_ The unit can not be restarted just after shut down. (RUN light is on) Restart is detayed for 3 minutes after shut down to protect the unit. Three=minute protection timer incorporated in the microcomputer actuates automatically Except when power is connected, this function does not actuate. Air does not blow out at starting of heat= ing operation. Air circulation is stopped to prevent blowing cold air into the room until heat exchanger warms up.
