Installation In Combination With Solar Or Gas Heaters - Hayward Spa Heaters 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 at (908) 355-7995. We
will advise you of installation practices that will help keep your warranty valid.
Other pool heaters, such as gas-fired or solar-powered devices must be in-
stalled in a parallel circuit and operated independently (only one at
a time) for your warranty to stay 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 in-
structions 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 Hayward heat pump unit.
