   Installation & Operation Manual

CAUTION

Use Teflon

®

 tape only on the threads of the pipe nipple 

attachment to the plastic header. Do not use any pipe 

compound or pipe dope on the threads or any part that 

comes into contact with the plastic headers. These 

compounds may damage the header over a period of 

time.

4. 

Wrap 5 or 6 turns of Teflon tape on the end of 

the pipe nipple and install a 3/8 NPT brass elbow 

while holding the pipe nipple from rotating. Orient 

the elbow to point straight up. See Figure 18.

5. 

Install a brass 3/4 NPT female to a 3/8 NPT male 

pipe adapter to the elbow using 5-6 turns of Teflon 

tape on the male end of the adapter. See Figure 18. 

6. 

Install the pressure relief valve on the elbow. 

Use 5-6 turns of Teflon tape on the male end of 

the valve. Install the pressure relief valve so it is 

vertical. See Figure 18.

7. 

Install a drain pipe from the pressure relief 

valve outlet to a safe area. This is a precaution 

to prevent the possibility of personal injury or 

property damage in the event scalding water is 

discharged from the pressure relief valve. 

Install the drain pipe so that there is no trapped or 

standing water in the piping. Drain piping must be 

facing down, terminating with a threadless nipple, 

no less than 6” from floor. It must be open with no 

reducers or shut-off valves or other restrictions.

NOTE:

  To ensure the continued proper operation of the 

pressure relief valve, the valve should be tested once 

a year. To test, lift the lever with the circulation system 

running  to ensure  that water will pass through. When 

the lever is down, there should be no leaks from the 

outlet.

5.8  Auxiliary Components, Chlorinators, 

Ozone Generators, and Sanitizing 

Chemicals

The JXi heater is manufactured with materials that are not 

compatible with high concentrations of ozone, chlorine, 

bromine, or other sanitizing chemicals. Heater damage 

caused by excessive chemicals or improper ozonization is 

not covered by the Zodiac Pool Systems, Inc., warranty. 

Be sure to adhere to the following:

•  When ozone is injected upstream of the heater, 

install an offgas mixing chamber, or an ozone bypass 

system between the heater and the ozone injector to 

prevent ozone and air from entering the heater.

•  When chemical feeders are used, plumb the feeder 

downstream of the heater and install an in-line check 

valve between the heater and the feeder (a minimum 

of 18 inch is required between the heater and the 

check valve).

•  Wire any electrical chemical feeder so that it cannot 

operate unless the filter pump is running. If the feeder 

has an independent clock control, synchronize it with 

the filter clock.

•  Never deposit chemicals directly in the pool 

skimmer.

Section 6.  Electrical 

Connections

 WARNING

ELECTRICAL SHOCK HAZARD. 

This heater contains 

wiring that carries high voltage. Contact with these 

wires may result in severe injury or death.

CAUTION

Label all wires prior to disconnection when servicing 

controls. Wiring errors can cause improper and dan-

gerous operation.

Verify proper operation after servicing.

6.1  General Information

Wiring connections must be made exactly as shown in 

the wiring diagram found on the inside of the heater door. 

The heater must include a definite means of grounding. 

There is a bonding lug on the right side of the heater, 

where a bond wire must be attached. For specific wiring 

connections, see Figure 19.
