Turbotemp 125 Pool and Spa Heater Installation and User’s Guide

ELECTRICAL CONNECTIONS

Electrical Rating 50 Hz 240 Volts AC, single phase

The heater is supplied with a 240V VAC, 10 AMP, 50 Hz power cord (AS/NZS 3112) approved
for outdoor use. The power cord wire is 3 x 16 AWG (3 x 10 mm2)

This heater is designed to operate at 240 VAC. It is not recommended to
be connected to OR operate on 208 VAC.

CAUTION

NOTE: If any of the original wiring supplied with this heater must be replaced, installer
must supply (No. 18 AWG, 600V, 105° C. U.L. approved AWM low energy stranded) copper
wire or it’s equivalent.

Please read the boxes headed “IMPORTANT! READ ME FIRST!” on pages 27 and 31 before
proceeding.
1. All wiring must be in accordance with all

applicable codes.

2. The heater, when installed, must be

electrically grounded and bonded in
accordance with local codes or, in the
absence of local codes, with the National
Electrical Standards. A bonding lug is
provided on the outside of the panel
under the vent for this purpose.

3. Electrical power circuits to the pool heater

must follow all applicable codes and
must be wired by a licensed electrician to
AS3000 Wiring Rules.

4. All wiring between the heater and devices

not attached to it, or between separate
devices which are installed in the field,
must be “Type T” wire rated for 35°C rise.

5. The filter pump should run continuously when the heater is on, and for at least 15 minutes

after the heater turns off. Any switches in the pump circuit (including circuit breakers) that
can disconnect the pump must also disconnect the heater.

6. Do not wire single-pole switches, including protective devices, into a grounded line. The

heater is not sensitive to polarity.

USE THE PROVIDED WATERPROOF WIRE NUTS WHEN CONNECTING THE POWER
SUPPLY.

A time clock controlling the filter pump should have a low-voltage Fireman’s Switch that
switches off the heater at least 15 minutes before shutting off the pump.

If, while there is line voltage connected to the heater, you
touch either line voltage terminal with any 24VAC wire that
is connected to the control board (including the Fireman’s
Switch jumper), you will immediately destroy the control
board and void the warranty.

CAUTION

CONNECTION OF FIREMAN’S SWITCH OR REMOTE CONTACT

REMOTE CONTROL CONNECTIONS

1.  Switch off power to heater at main circuit breaker panel.
2.  Unbolt and remove the access door panels.
3.  Open control box cover (see Figure 33).
4a.

To connect a 2-Wire Control (IntelliTouch® or EasyTouch®
Control System) or a timer:

-  Remove the factory installed jumper from the Fireman’s
  Switch terminals.
-  Connect wires between the Fireman’s Switch terminals on

the heater and the relay. Connect wires from the controller
or timer to the Fireman’s Switch. Controller, timer or relay
should be sized to handle 24VAC at 0.5
Amp (because it will be completing the
24VAC control board circuit on the heater
as shown in Figure 34). DO NOT apply line
voltage to the Fireman’s Switch terminals.
Use 18 gauge wire with a minimum 1.2
mm (3/64 in.) thick insulation rated for a
temperature rise of at least 105°C.

- Knock-outs are provided to route the wires

through the bottom of the control box and
past the junction box.

4b.

To connect a 3-Wire Control:

- Connect wires between the control board

terminals on the heater and the external
relays, as shown in Figure 33. Use at least
2 relays per heater, to allow for an “OFF
setting” on each heater mode. Select relays
that can handle logic level switching. DO
NOT apply line voltage to control board
terminals.

- Move jumper (as shown in Figure 34) to

enable external control and to disable the
heater membrane pad’s “Pool ON” and
“Spa ON” buttons (the “OFF” key on the
membrane pad remains functional).
