Model LC (Australia) Pool and Spa Heater

To install a time clock switch into the heater
wiring, follow these steps (see Fig. 6):
1. Remove the heater door.
2. Remove the factory-installed wire between
terminals 1 and 2 on the terminal block (see Fig. 7).
3. Connect the wires from the time clock auxil-
iary switch to the two terminals. Use 14 gauge copper
wire with insulation at least 1.2 mm thick, and tem-
perature rating of 221°F (105°C) or greater.
2E-2. Remote Operation
The Model LC (Australia) pool/spa heater
controls can be wired for remote operation. Two
Waterpik Technologies remote control models are
available through the local dealer or distributor. The
CS-07 remote control permits switching from one
temperature controller to the other and turning the
heater on and off from a remote location. The CS-08
includes the same features as the CS-07 plus a remote
temperature controller.
An interrupt (On-Off) type remote can be con-
nected by removing the jumper wire on the terminal
block located in the control compartment (see Fig. 7)
and connecting the two wires from the remote to the
two terminals on the terminal block. This type of
remote control will turn the heater on or off, but will
not switch between the two temperature controllers on
the Flex-Temp control panel.
To connect a 3-wire remote (not supplied by
Waterpik Technologies), order a wire harness assem-
bly (part No. E0120000) which connects to the Flex-
Temp control panel. Installation instructions are
included with the wire harness assembly.
2F. Water Piping
The heater has 50 mm universal header
couplings. You can connect threaded 50 mm iron or
copper pipe, unthreaded 38 mm iron or copper pipe
using the special gaskets packaged with these
instructions, and CPVC pipe by first fitting the
CPVC nipples provided with the heater into the coupling
(see Fig. 8).
You can connect high-temperature plastic piping
(CPVC Schedule 80) to the inlet/outlet header if local
codes allow it, and the controls keep the filter pump
running at least 15 minutes after the heater is turned off.
NOTE: Do not use PVC plastic materials in pipes,
fittings, grids and other elements of the filter system
unless a metal "heat sink" pipe is used between the
filter and the heater (see Fig. 9).
NOTE: The pool heating system must have a
manual reset high limit installed in accordance with
AS2610, Section 2.7 (see Fig. 9). Contact a local
installer or distributor.
