WATER PLUMBING
The piping sequence: pool pump / filter / heater / Chlorinator / Pool. In-line
chlorinators must be down stream of the heater to minimize harm to the
pool equipment. Rigid PVC piping is recommended and all joints should be
secured with PVC glue. Make sure that the direction of the water flow
through the heater is correct as indicated by the labels on the unit. When
the piping installation is complete, operate the pool pump and check the
system for leaks. Check the filter pressure gauge to ensure that excessive
pump head pressure is not indicated.
The recommended flow rate is 50 gpm through the heater.
For questions on multiple heater installations, please contact our
engineering department. Multiple unit installations should always be in
parallel circuits.
ELECTRICAL HOOK UP
CAUTION: The main power disconnect must be off before opening the
access panel.
It is recommended that the wiring of your heater be done by a qualified
electrician in accordance with local code requirements.
IMPORTANT: The electrical conduit
must be run up through the base of
the unit and connected at the control box with a conduit connector.
A properly sized breaker and copper wire must be used. See inside access
panel for wiring diagram.
