Unit Location — The Q4 series heat pump is
designed only for outdoor installations. Choosing
the location of the unit should be based on
minimizing the length of the supply and return
ducts. Consideration should also be given to
availability of electric power, service access,
noise, and shade. Sufficient clearance for
unobstructed airflow through the outdoor coil
must be maintained in order to achieve rated
performance See Figure 4 for minimum
clearances to obstructions.
Air Filters — A suitable air filter must be installed
in the return air system. Air filter pressure drop
must not exceed 0.08 inches w.c. at 300 fpm.
Condensate Drain — Condensate is removed
from the unit through the 3/4" female pipe fitting
located on the front side of the unit. (See Figure
5.) Install a 2 inch condensate trap in the drain
line of the same size and prime with water.
When connecting rigid drain line, hold the female
fitting with a wrench to prevent twisting. Do not
over tighten! Refer to local codes and
restrictions for proper condensate disposal
requirements.
