Connect the L1 of the power supply to the black wire, the
L2 or neutral lead to the red 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.

NOTICE: 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 (includ-
ing 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 line
voltage power from the 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).
to
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" (1.2mm) 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).
