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 (See Figure 23).
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.
FIREMAN’S SWITCH CONNECTION
NOTICE: If, while there is 120VAC connected to the
heater, you touch either 120VAC 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.
NOTICE: When using a timer and Fireman’s Switch, the
heater’s power supply should come from the load side of
the timer. The Fireman’s Switch completes the circuit for
the low voltage safety switches. It DOES NOT get any
power from the 115 volt power supply.
Connect the Fireman’s switch to the heater as follows:
1. Turn off power to heater at main circuit breaker panel.
2. Unbolt and remove the upper jacket halves (see Figure
3, Page 5).
3. Open control box cover (see Figure 24).
4. Remove the factory-installed jumper between the
Fireman’s Switch terminals (see Figure 25).
5. Connect the wires between the Fireman’s Switch termi-
nals on the heater and those on the time clock using
18 gauge wire with a minimum 3/64” thick insulation
rated for a temperature rise of at least 105°C. Route the
wires out through the knockout on the bottom of the
Control Box. Use a 90° conduit el and conduit run out
through the cutout on the Lower Enclosure, next to the
Junction Box (see Figure 23).
