Transformer Wiring

120 VAC Wiring
For 120 VAC input power to the unit, connect the field-
supplied Black wire (L1) to the (2) Black wires from the
heater. Connect the white and red/white wires to the "N"
or Neutral leg of the power supply. There should be no
connection to the red wire for 120 VAC operation.
Attach a wire nut to the red wire.
Figure 29. 120 VAC Wire Connection
Figure 30. 120/240 VAC Blower Jumpers
CAUTION: The heater is prewired with a 240V connector
to the blower. If the supply voltage is 120V, replace
the connector with the supplied 120V (red connector).
Using the wrong corresponding connector will cause
electrical damage.
240 VAC Wiring
For 240 VAC input power to the unit, connect the black
wires to the L1 or hot leg of the power supply. Connect
the red and red/white wires to the "L2" or second hot leg
of the power supply. There should be no connection to
the white wire for 240 VAC operation. Attach a wire nut
to the white wire.
A WARNING: DO NOT attempt to operate the heater
at 208 VAC.
Figure 31. 240 VAC Wire Connection
The heater must be electrically grounded and bonded in
accordance with local codes, or, in the absence of local
codes, with the latest edition of the National Electrical
Code, ANSI/NFPA 70. (Canada - Canadian Electrical
Code, CSA C22.1, Part 1 and Part 2.)
:
CAUTION
If the transformer's primary side is wired for
120 VAC and 240 VAC is applied, damage to the trans-
former and PC board may result. Such damages are not
covered under manufacturer's limited warranty.
NOTE: Input power to the heater (120 or 240 VAC) can
be supplied from the load (pump) side of time clock or
directly from the GFCI power source. It is preferred that
full-time power be supplied to the heater from the GFCI
power source, and that the heater be controlled by the
fireman's switch connection or using a two or three-wire
remote. If using a switched GFCI power source, the heater
could display false service indicators on the display panel
if the pump is turned off.
