A pressure relief valve is not supplied with the
heater. However, it may be required by local codes.
The pressure rating of the valve should be at or below
the lowest working pressure of any component in the
filter system. Any pressure relief valve installed must
comply with provisions of the Standard described in
ANSI Z21.22 for the United States, or CSA 4.4 in
Canada.
To install a pressure relief valve, do the follow-
ing:
1.
Remove the 3/4 inch (19 mm) brass plug located
on the top of the inlet/outlet header (see Figure
14).
2.
Install the pressure relief valve in the threaded
hole from which the plug was removed.
3.
Be sure that the exhaust port of the PRV is
plumbed so that any hot water is directed safely
away from any public areas and away from any
area occupied during servicing.
5.7 Auxiliary Components, Chlorinators,
Ozone Generators, and Sanitizing
Chemicals.
The Lite2 heater is manufactured with materials
that are not compatible with high concentrations of
ozone, chlorine, bromine, or other sanitizing chemi-
cals. Heater damage caused by excessive chemicals or
improper ozonization is not covered by the Jandy Pool
Products, 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.
