Heat Pump Maintenance & Precautions
Air Flow & Access Clearances
AIR COIL
(on 3 Sides)
BASE
(CONCRETE OR PREFAB)
1. Make sure the unit has a firm base. The heat pump will produce condensation
(water) while in operation. You will notice water coming from the bottom drain ports
when the unit is running. The condensation will increase as the outdoor air humidity
level increases.
Make sure the bottom drain ports do not become clogged with debris. Make sure the
run off water does not puddle inside the heater and does not undermine the equip-
ment base.
2. Keep the top air flow discharge & air flow intake area clear as shown here so the air
flow through the heater is not restricted. Make sure the unit can "breathe" well. The
cooler discharge air from the top should not accumulate and be drawn into the side air
intake coils. Keep all plants and shrubs trimmed away from the heater. Make sure the
front is accessible for future service.
3. Do not allow lawn sprinklers to spray on the heater in any way. Keep sprinkler heads
away from the heat pump to prevent corrosion and damage. Use a deflector if needed.
4. If the unit is installed under a very sharp roof pitch or under a roof valley that has no
gutter, a gutter or diverter should be fitted to prevent excessive water from pouring
through the unit.
