CONDENSATE
DRAIN
LINE
The condensate drain exits the unit 2" above floor level at the right side front corner of the unit. The condensate drain line
is already internally trapped therefore, no external condensate trap is required.
Install a condensate drain line of the same size as the drain fitting on the unit. PVC plastic pipe (3/4 in. I.D.) makes an ideal
condensate line (if local codes allow).
Run condensate drain line from unit to floor drain or outside perimeter of building per local codes.
The condensate line must have a minimum drop of 1/4" per running foot as it leaves the unit. When a horizontal run of 15
ft. or longer is required, it may be necessary to install a vent tee in the drain line near the unit or use a larger diameter drain
line. This is to eliminate air trapping and allow proper condensate drainage.
Heat pumps generate condensate
during both cooling and heating modes.
Condensate
drain line must be
protected from freezing to prevent condensate from backing up in unit during freezing outdoor conditions.
See
page 4 for Cold Climate accessories.
NOTE: If the unit is to be installed in an attic or furred space where damage may result from condensate overflow, it may
be necessary to provide a field-supplied secondary drain pan. Always refer to local and national codes.
INSTALLATION
- FINAL
CHECKLIST
[]
Is power to the unit ON?
[]
Are circuit breakers/power
disconnect inside of the unit
ON?
[]
Is ductwork sealed for
airtight
an
fit?
[]
Is the condensate drain line
installed and run to an
appropriate disposal site.?
Test
Run
Test run in Heating, Cooling, and Emergency Heat mode as follows:
[]
Is the thermostat level and
properly installed?
[]
Is the heat anticipator indicator
set to the correct setting.?
a.
b.
C.
d.
Set fan control to ON. If fan runs, return control to AUTO setting. This verifies fan is working properly.
Set system control from OFF to COOL. Lowertemperature selector to 50 ° For lower. The compressor should energize
and cool air should flow from room registers. Once cooling test is complete, return system control to OFF setting.
Wait 5 minutes.
Set system control to H EAT and raise temperature selector to 80°F or higher. Compressor should energize, and warm
air should flow from room registers.
Set system control to EM HEAT (Emergency Heat). Compressor should turn offand warm air should continue to flow
from the registers. (This step is for heat pumps only.)
NO TE: During EM HEA Toperation, temperature of air flowing from room registers may be slightly warmerthan during
normal HEA Tmode operation.
Leave this manual with owner or user of equipment.
After 72 hours of operation, the unit will achieve full rated operating performance.
