1. Wiring must be sized per National Electrical Code requirements based on the pump load and
conductor length.
2. Conductors must be installed in approved conduit.
3. The pool heater, the pool pump, and the pump timer must be grounded per National Electrical
Code requirements.
Open the pool timer and connect a second set of wires to the line side terminals. Use a length of
watertight flexible conduit to connect to the Pool Heater cabinet, entering through the openings
provided on rear of the cabinet. Remove the left panel from the pool heater. Connect to the black
wires labeled #1 and #2 hanging from the Pool Heater’s control box.
Open the junction box on the pool pump and connect a second set of wires to the pump terminals.
Use a length of watertight flexible conduit to connect to the Pool Heater cabinet, entering through
the openings provided on the rear of the cabinet. Connect to the pair of blue wires, labeled #1 and
#2, found hanging from the Pool Heater’s control box. Be sure that the polarity is correct.
Replace the left panel on the cabinet.
POOL PIPING CONNECTIONS
The Pool Heater is designed to handle the full flow from the pool pump. No bypass is required if the
water flow is in the 20 to 80 gallon per minute range. See Figure 4.
The Pool Heater piping must be connected at a point in the pool piping loop after the pool water
passes through the filter and before the chlorinator or chemical feeder. Connecting the Pool Heater
after the chlorinator will cause premature failure of the Pool Heater.
While this unit contains a
specially coated heat exchanger to resist chlorine, failure to maintain proper pool chemistry
will significantly shorten the life of the Pool Heater and may not be covered under Factory
Warranty.
To prevent back-siphoning of the chlorinator when the pool pump is turned off, install a
chemically resistant check valve and a piping loop that extends at least 8 inches above the top of the
chlorinator.
The Pool Heater comes equipped with clear PVC stubs to allow a visual check of water flow and
water condition. Connect to these stubs with 2 inch PVC couplings and an appropriate length of 2-
inch PVC pipe; taking care to note which stub is “water in” and which is “water out”.
Good practice also suggests considering the use of 3 way valves on the inlet and outlet to enable
the pool owner to bypass the Pool Heater if service or maintenance is required.
