SYSTEM DESIGN SUMMARY
1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than
0.01−in. wc.
2. This product is not qualified for low ambient cooling operation.
Minimum cooling outdoor operating temperatures:
− Communicating systems: 40_F (4.44_C)
− Non−communicating systems: 55_F (12.8_C)
3. The maximum outdoor operating ambient in cooling mode is 115_F (46.11_C).
4. Minimum outdoor operating air temperature for heating mode is 10_F (–12.2_C).
5. Maximum outdoor operating air temperature for heating mode is 66_F (18.9_C).
6. For reliable operation, unit should be level in all horizontal planes.
7. This unit is qualified for up to 100 ft (30.5 m) equivalent length of line set without additional accessories.
8. If any refrigerant tubing is buried, provide a 6 in. (152.4 mm) vertical rise to the valve connections at the unit. Refrigerant
tubing lengths up to 36 in. (914.4 mm) may be buried without further consideration. Do not bury refrigerant lines longer
than 36 in. (914.4 mm).
9. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of con-
nector provided.
10. Do not apply capillary tube indoor coils to these units.
11. R−410A refrigerant TXV required on indoor coil.
Accessory Description and Usage

Raises unit above base pad. 2 and 3 ton kit contains 5 feet for
stable installation with small base. 4 and 5 ton kit contains 4
feet.
Usage Guideline:
Recommended in cold climates where snow can
accumulate around unit. Allows improved base pan drainage.
Recommended for rooftop applications.
Thermostatic Expansion Valve (TXV)
A modulating flow−control valve which meters refrigerant liquid
flow rate into the evaporator in response to the superheat of
the refrigerant gas leaving the evaporator.
Usage Guideline:
Required if indoor unit does not already contain
R−410A refrigerant TXV
Vapor Line Muffler
An external muffler installed in the vapor line to minimize
vibration transmitted through refrigerant lines
