Capacity (1 000 Btuh), includes fan motor heat and deduction
for thermal line losses of 1 5 ft of piping exposed to outdoor
conditions
Power input includes compressor motor power input, indoor
and outdoor fan motor input
Integrated Heating Capacities — Values shown reflect a capacity
reduction at those outdoor air temperatures at which frost forms on
outdoor coil

NOTE
Heating ratings shown in table are without accessory electric heater
and are based on 70 F db air entering indoor coil, 85% rh air entering
outdoor coil, and ARhrated cfm See Heating Capacity Correction
Factors table to calculate heating capacity and power input at other
cfm's and indoor coil entering air temperature

‘Recommended vapor line insulation for piping exposed
to outdoor conditions to prevent loss of heating during
heating cycle When vapor line goes thru interior
spaces, insulation should be selected to prevent con­
densation on cooling cycle Heating capacity should be
reduced 1000 Btuh if over 35 ft of vapor line with
3/4-in insulation is exposed to outdoor conditions
(Closed cell foam plastic insulation with a thermal con­
ductivity of 28 Btuh/sq ft/F/inch
NOTE Vapor lines of accessory precharged tubing pack­
ages (available for use with 38HQ units) are insulated
with closed cell foam plastic insulation with a thermal
conductivity of 28 Btuh/sq ft/F/inch

NOTES
1 All units have 24-v control circuit which requires external power source
2
Use copper or copper-clad aluminum wire only for compressor section; copper
wire only for outdoor coil section See Installation, Start-Up and Service
Instructions
3 Units require field-supplied grounding wire See Installation, Start-Up and
Service Instructions for wire sizes
