Heat pump heating performance continued
NOTE: When the required data falls between the published data, interpolation may be performed. Extrapolation is not an acceptable practice.
* The Btuh heating capacity values shown are net integrated values from which the defrost effect has been subtracted. The Btuh heating from sup-
plement heaters should be added to those values to obtain total system capacity.
† The kW values include the compressor, outdoor fan motor, and indoor blower motor. The kW from supplement heaters should be added to these
values to obtain total system kilowatts.
EDB – Entering Dry-Bulb
System Design
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. Minimum outdoor operating air temperature for cooling mode without low-ambient operation accessory is 55°F (12.8°C).
3. Maximum outdoor operating air temperature for cooling mode is 125°F (51.7°C).
4. Minimum outdoor operating air temperature for heating mode is –30°F (–34.4°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. Maximum elevation of indoor coil above or below base of outdoor unit is: indoor coil above = 50 ft, indoor coil below = 150 ft.
8. For interconnecting refrigerant tube lengths greater than 50 ft horizontal or 20 ft vertical differential, consult Residential Split-System Long-Line
Application Guideline available from equipment distributor.
9. For more than 36 in. of refrigerant tubing buried in the ground, consult your local distributor.
10. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
11. Mismatches of indoor coil capacity more than 1 size larger than outdoor unit capacity may result in inadequate indoor comfort.
