Operation (contd.)
AUXILIARY (AUX)
When this light is on it indicates the remote switch
contacts are closed. This allows you to observe if
your remote switch is properly closing the heater
control circuit. When shipped from the factory a
jumper is installed to maintain closed circuit in the
absence of a remote switch.
PRESSURE (PRESS)
This light is on when Spa/Pool Selector switch is
on, indicates the circulation pump is running prop-
erly. If pressure light fails to light, the pump may
have lost its prime or water flow may be restricted
by an inadvertently closed valve or clogged filter or
pump basket. If you have determined that there is no
water flow restriction to the heater, you should call
a qualified serviceman.

The service light is off during normal operation of
heater. The light only comes on if a problem with a
control has occurred or when the heater is first
firing. The problem must be investigated by the
serviceman prior to attempts to fire the heater again.
