Parts Needed
Check local codes and HVAC supplier. Check existing electrical 
supply, and read “Electrical Requirements,” “Location 
Requirements,” “System Requirements” and “Connect 
Refrigerant Lines.”
System Requirements
Heat pump system matches are derived from actual laboratory 
testing of matched systems. It is recommended that only 
matching equipment be used to ensure proper operation and 
efficient performance.
The designed system matches are listed in the heat pump 
unit specification sheets and on the heat pump refrigerant 
charging instructions located on the back of the service 
access panel.
Refrigerant charging instructions include a list of matching 
indoor equipment with the proper thermal expansion valve 
size and amount of refrigerant charge required.
This heat pump has been factory charged with a quantity of 
refrigerant (R-410A) sufficient for a matched indoor coil and a 
maximum 15 ft of refrigerant line.
In order to maintain the 16 SEER rating, this heat pump must 
be matched with an indoor section containing a variable 
speed blower.
Refer to the refrigerant charge label located on the inside of 
the heat pump access panel for the correct thermal 
expansion valve size required. 
This product has been designed and manufactured to meet 
ENERGY STAR
® 
criteria for energy efficiency when matched 
with appropriate coil components. However, proper 
refrigerant charge and proper airflow are critical to achieve 
rated capacity and efficiency. Installation of this product 
should follow the manufacturer’s refrigerant charging and 
airflow instructions. Failure to confirm proper charge and 
airflow may reduce energy efficiency and shorten equipment 
life.
A filter drier approved for use with R-410A refrigerant is 
installed in the heat pump.
If this condensing unit is equipped with a crankcase heater, it 
should be energized 24 hours before the condensing unit is 
started to prevent compressor damage as a result of 
slugging.
Use only polyol ester oils if oil must be added to the system. 
Mineral oil is not compatible with refrigerant.
Indoor System Thermal Expansion Valve
W4GH6 units are designed for use with thermal expansion 
valve systems only. The thermal expansion valve must be 
ordered separately from the manufacturer. 
Location Requirements
This heat pump is designed to be located outdoors with 
sufficient clearance for free entrance to the inlet and 
discharge air openings. The location must also allow for 
adequate service access. See “Minimum Clearances.”
Where possible, select a location for the heat pump which is 
shaded from the direct rays of the sun most of the time. North 
or east locations are usually most desirable. Position the heat 
pump to avoid direct contact with water, snow or ice from a 
roofline overhead. 
The heat pump must be installed on a solid, level mounting 
pad that will not settle or shift. Isolate the pad from the 
building structure to avoid possible transmission of sound or 
vibration from the heat pump into the conditioned space.
The heat pump foundation should be raised to a minimum of 
3" above finish grade. In areas which have prolonged periods 
of temperatures below freezing, and/or snowfall, the heat 
pump should be elevated above the average snow line. If 
heat pump is to be installed on a flat roof, it should be on a 
platform or other support which will raise the inlet air opening 
12" minimum above the surface of the flat roof.
Care should be taken to ensure free drainage of condensate 
from defrost cycles. This will prevent ice accumulation. The 
heat pump should be located away from walkways to prevent 
possible icing from defrost condensate.
Avoid placing the heat pump near areas such as sleeping 
quarters or study rooms. Normal operating sound levels may 
be objectionable if the heat pump is placed near certain 
rooms. A shift in sound type does occur during the defrost 
mode. The defrost mode generally lasts no longer than 
10 minutes.
