Heat Pump Swimming Pool Heaters
INSTALLATION INSTRUCTIONS
Location of SubZero
The location of the pool heater is very important in keeping installation costs to a minimum,
while providing for maximum efficiency of operation as well as allowing adequate service and
maintenance access.
Mount the unit on a sturdy base, preferably a concrete slab or blocks which are elevated
from the ground. For the concrete slab, it is necessary to support the drainage of water by
establishing a gravel tank of 8 inches in width by 5 inches in depth.
The base should be completely isolated from the building foundation or wall to prevent the
possibility of sound or vibration transmission into the building. The size of the base should
not be less than the base of the pool heater.
Your Heat Pump will accumulate condensed water (approx. 1 to 1.5 Gallons or 4 to 6
Litres per hour), therefore causing water to drain out of the unit base.
Air is pulled through the evaporator coil and discharged through the top grill. Clearance
should be allowed in front and around the unit for unrestricted air discharge and service
access. See Figure 1.
