Heat Pump Pool / Spa Heater Owner's Manual INSTALLATION IN COMBINATION WITH SOLAR OR GAS HEATERS If you are installing a heat pump in combination with any other type of heating device, please call the HAYWARD service department. We will advise you of installation practices that will help keep your warranty valid. If you are installing other pool heaters, such as gaspowered or solar-powered devices: 1. They must be installed in a parallel circuit and operated independently (only one at a time) for your warranty to stay valid. Because of the intense heat that can be generated by gas and solar units, the heat pump is protected by isolating it with shut-off valves and a check valve when gas or solar is in operation. OR 2. Installation of a heat pump and solar unit in series is achieved by plumbing to this diagram. If you wish to only run the secondary heater, you can turn the heat pump to "off" and still allow water to flow through it. Placing a check valve in the line to prevent backflow of hot water from the secondary heater is critical to the warranty and life of your heat pump. 29

INSTALLATION IN COMBINATION WITH SOLAR OR GAS HEATERS
If you are installing a heat pump in combination with any other type of heating device, please call the
HAYWARD service department. We will advise you of installation practices that will help keep your
warranty valid.
If you are installing other
pool heaters, such as gas-
powered or solar-powered
devices:
1.
They
must
be
installed in a
parallel
circuit and operated
independently
(only
one at a time) for
your warranty to stay
valid
. Because of the
intense heat that can
be generated by gas
and solar units, the
heat
pump
is
protected by isolating
it with shut-off valves
and a check valve
when gas or solar is in
operation.
OR
2.
Installation of a heat pump
and solar unit in series is
achieved by plumbing to
this diagram. If you wish to
only
run
the
secondary
heater, you can turn the heat
pump to “off” and still allow
water to flow through it.
Placing a check valve in the
line to prevent backflow of
hot
water
from
the
secondary heater is critical
to the warranty and life of
your heat pump
