Heat pump and Heater Combination
In certain regions of the country it may be more
economical to run a heat pump during the warmer
months and a gas heater during the cooler months.
In some situations it may be desirable to run the heat
pump in the “Chiller” mode during the hottest portion of
the year and a heater during the cooler months.

heat pump may be plumbed with a gas
or electric heater or any combination of heat sources
including solar. All heat sources must be plumbed in
series to work correctly and efficiently.
Figure 5 illustrates a recommended plumbing layout
for a heat pump / heater / solar combination heating
system for a pool / spa combination. Your system may
not contain all of these components, but the basic
plumbing will apply by eliminating the component in
the illustration that is not a part of your system.
Multiple Heat pump Connections
All plumbing on multiple heat pump installations must
be done in parallel (see Figures 6 and 7). An equal flow
of water to each heat pump is important for optimum
operation.
notE
It may be necessary to adjust water pressure
switch if a unit is installed below the water level.
See Section 5.6 for details on when and how to
adjust the pressure switch.
notE
Each heat pump allows a maximum flow rate of
70 gpm (265 lpm) and requires a minimum of
20 gpm (76 lpm).
section 4. Electrical Connections
4.1
General information
Wiring connections must be made exactly as shown in
the wiring diagram found on the inside of the heat pump
access compartment (see Figure 8 for single phase
electrical wiring and Figure 9 for 3-phase electrical
wiring). The heat pump must include a definite means
of grounding and bonding. There is a bonding lug on the
right side of the heat pump, where a bond wire must be
attached.
