SECTION TWO – Heater Installation

Power Supply Requirements

Heaters built before 4/27/04 require a line voltage sup-

ply of 115-120 VAC, single-phase, 60 Hz. Heaters built

on or after 4/27/04 can use either 115-120 VAC or 240

VAC. You must install the correct 12-pin plug in the

control box before operating the heater (See Page 7-1

for instructions). The line voltage power supply to the

heater must be enclosed in an approved flexible con-

duit connected directly to the junction box located

inside the heater jacket.

(See Figure 2-13)

Line voltage field wiring should be 14 gauge, with a

circuit capacity of 15 amps. Connect the hot lead of the

power supply to the black wire, the neutral lead to the

white wire, and the ground wire to the green wire.

1. All wiring must meet applicable code requirements.

2. Electrically ground and bond the heater in accor-

dance with local codes or, in the absence of local

codes, with the National Electrical Code,

ANSI/NFPA 70, or Standard CSA C22.1 - Canadian

Electrical Code, Part 1. A bonding lug is provided

on the outside of the jacket under the junction box

for this purpose.

3. Electrical power circuits to the pool heater must fol-

low local codes and National Electrical Code or

Canadian Electrical Code (as applicable).

4. Use Type T (35°C rise) wire for all wiring between

the heater and devices not attached to it.

5. Enclose all line voltage wiring in approved flexible

conduit, and securely attach it to the field wiring

junction box molded into the lower jacket. To

reduce abrasion where the flexible conduit enters

the junction box, install an insulating bushing or its

equivalent on the conduit.

6. TT

(see “Fireman’s Switch” below). Any

switches installed in the pump circuit (including the

circuit breaker) that can disconnect the pump must

also disconnect the heater.

7. Do not install single pole switches, including pro-

tective devices, into a grounded line. Observe

hot/neutral polarity when connecting power to the

heater .

fying them as dual-voltage equipment. See Page 7-1 for more information about the 12-pin plug.
