Installation Above Pool/Spa Surface
If the heater is installed more than three (3) feet above the surface of
the pool/spa water, install a loop as shown in Figure 7 to prevent drain-
age of water in the heater during a filter change.
Typical Pool Arrangement
Figure 8 illustrates a typical pool piping diagram and layout for the pool
equipment. Also shown is implementation of an optional Gas or Solar
heater system for additional capacity. Other pool heaters, such as gas-
fired or solar-powered devices must be installed in a parallel circuit and
operated independently (only one at a time) for your warranty to be valid.
NOTICE - Because of the intense heat that can be generated by gas
and solar units, isolating it with a shut-off valve and a check valve when
gas or solar heater is in operation protects the heat pump. Failure to
follow the instructions may result in property damage.
Notes:
1. Isolate the heat pump from hot water flow of heating
devices such as gas or solar heater.
2. Install bypass loop for heat pump unit.
Figure 9 illustrates a multiple heater installation for very large pools with
and without a manual bypass valve.
1. Maintain 4-6ft [1,2-1,8 m] clearance between the units, 2ft
[0,6 m] around perimeter, and at least 6ft [1,8 m] over them.
Refer to LOCATING THE HEATER section for more details.
2. Install bypass loops for each unit.
3. Install union style fittings from the heat pump CONSUMER KIT
adjacent to the unit to facilitate easy service procedures
