Model LD Pool and Spa 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).
• 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.
WARNING
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after
servicing.
AVERTISSEMENT
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. S'assurer que l'appareil
fonctionne adéquatement use fois l'entretien terminé.
WARNING
Ensure that power is turned off at the source circuit
breaker before attempting any service to the
appliance.
AVERTISSEMENT
Assurez-vous que le courant est coupé au
disjoncteur de source avant d'essayer n'importe quel
service à l'appareil.
Wiring connections must be made exactly as
shown in the wiring diagram found on the inside of the
heater (see Figure 16, following page). The heater
must include a definite means of grounding.

6.1 Main Power

The heater comes factory-wired intended for
use with 240 Volt, 60 Hz AC field electrical
supply. To use 120 Volt, 60 Hz AC requires
rewiring of the heater. This should be done by a
certified electrician only, as with all wiring. To wire
the heater for 120 Volt, 60 Hz AC, follow the alternate
120V wiring method depicted in Figure 6. Additionally,
the ignition control module must be rewired. The wire
from the terminal marked IGN/240 must be removed
from that terminal and placed on the terminal marked
IGN/120.
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.
In Canada, the Canadian Electric Code (CEC), CAN/
CSA C22.1 applies.
To wire the Lite2 model LD heater to a
120V or 240V /60 Hertz (Hz) electrical source:
1. Remove the screw located to the lower right side
of the transformer and open the hinged cover of
the wiring enclosure.
2. Connect the wires from the power source to the
leads on the right side of the heater in the space
behind the ignition control (see Figure 8). Be sure
to follow the wiring diagram on page 7 to config-
ure the transformer for the correct input voltage.
3. Attach the ground wire to the green ground
screw located on the back panel of the wiring
enclosure.
4. Close the cover of the wiring enclosure and
replace the screw to hold it in place.
NOTE: No external junction box is required.

6.2 Bonding

CAUTION
This heater must be connected to a bonding grid with
a solid copper wire not smaller in diameter than 8 ga.
ATTENTION
L'appareil de chauffage doit être connecté à une grille
de mise à la terre par un fil de cuivre d'un diamètre
de calibre minimal 8.
The National Electrical Code and most other
codes require that all metallic components of a pool
structure, including reinforcing steel, metal fittings and
above ground equipment be bonded together with a
solid copper conductor not smaller than a number 8
wire. The heater, along with pumps and other such
equipment must be connected to this bonding grid. A
special labeled bonding lug is provided on the right side
of the heater to accommodate this requirement.

6.3 Auxiliary Time Clock Wiring

If you install a time clock to control the filter
pump operation, it is recommended that the time clock
have its own low voltage (Fireman's) switch to turn
off the heater before turning off the pump. The switch
should shut off the heater about 15 minutes before the
filter pump shuts off. This will allow for a more
efficient operation by removing any residual heat
contained in the heat exchanger back to the pool.
To install a time clock auxiliary switch into the
heater wires (see Figure 15):
