12.
Wrap the threads of the adapter with a suitable
teflon thread tape.
13.
Reinstall the adapter, with the PRV, into the
plastic threaded hole and tighten it until the mark
on the adapter is once again facing the same
direction as the water connections on the header.
CAUTION
Do not use any pipe compound or pipe dope on
the threads of the adapter or any part that
comes in contact with the plastic headers.
These compounds may damage the header
over a period of time.
ATTENTION
N’utilisez ni pâte à joint ni pâte lubrifiante sur le
filetage du raccord intermédiaire ou sur toute
pièce qui entre en contact avec le tuyau
collecteur. Ces produits risquent
d’endommager le tuyau après un certain
temps.
DO NOT TIGHTEN WITH A WRENCH.
Overtightening may crack the header. Route the
discharge piping so that discharge from the pipe does
not endanger anyone near the heater. Refer to your
local installation codes for more detailed information.
The valve setting should be at or below the maximum
working pressure of any component in the filter
system. The maximum working pressure of the LX
and LT Low NOx heater is 75 psig.
5.7 Auxiliary Components, Chlorinators,
Ozone Generators, and Sanitizing
Chemicals
The LX and LT Low NOx heaters are manufac-
tured 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 Waterpik Technologies 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" 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.

Electrical
WARNING
ELECTRICAL SHOCK HAZARD.
This heater
contains wiring that carries high voltage.
Contact with these wires may result in severe
injury or death.
AVERTISSEMENT
POSSIBILITÉ DE CHOCS ÉLECTRIQUES. Ce
système de chauffage contient du filage de
haut voltage. Un contact avec ces fils peut
résulter en des blessures sérieuses ou la mort.
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
Verify proper operation after servicing.
ATTENTION
Au moment de l'entretien des commandes,
étiquetez tous les fils avant de les débrancher.
Des erreurs de câblage peuvent entraîner un
fonctionnement inadéquat et dangereux.
6.1 General Information
Wiring connections must be made exactly as
shown in the wiring diagram found on the inside of the
heater door (see Figure 18). 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.
6.2 Main Power
Electrical wiring must be in accordance with the
latest edition of the National Electric Code (NEC),
ANSI/National Fire Protection Association (NFPA)
70, unless local code requirements indicate otherwise.
The heater comes factory-wired intended for
use with 230 Volt, 60 Hz AC field electrical
supply. To use 115 Volt, 60 Hz AC requires
changing the position of the voltage selector
board on the power distribution board.
This must
be done by a certified electrician only, as with all
wiring. Be sure that the power source to the heater is
turned off or disconnected before servicing.
