The five operating switches are:
POOL ON Press this button to govern heater operation by
the pool temperature setting.
SPA ON Press this button to govern heater operation by the
spa temperature setting.
OFF Press this button to switch off the heater.
▲
TEMP Press this button to raise the temperature setting.
▼TEMP Press this button to lower the temperature setting.
To toggle the display between degrees Centigrade (°C) and
degrees Fairenheit (°F):
1. Turn the Operating Control OFF.
2. Press
▲
TEMP or ▼TEMP for 5 seconds. The display
will flash once and change modes (°C to °F or vice
versa).
When either the
▲
TEMP or ▼TEMP buttons are depressed,
the digital display will indicate the temperature setting.
After five seconds, the display will return to the actual
pool/spa temperature.
In addition to the digital temperature display, there are five
indicator lights:
The POOL ON light indicates that the pool water tempera-
ture is governing operation of the heater.
The SPA ON light indicates that the spa water temperature
is governing operation of the heater.
The HEATING light comes on and stays on when the burn-
er is firing. This light should be on whenever the burner is
on. It blinks when the heater is calling for heat but not fir-
ing. If this light is on but the burner fails to come on, one
of the “service” lights should come on, indicating a fault in
the system.
The SERVICE SYSTEM light indicates that there is insufficient
water flow to the heater. If the pump is operating, this usual-
ly indicates that the filter and/or skimmers should be cleaned
(some filters may require backwashing). If the light remains
on after the filter/skimmers have been serviced, the system
should be checked by a qualified service technician.
The SERVICE HEATER light indicates a fault in the heater
or its controls. If this light comes on, shut down the heater
(See TO TURN OFF GAS TO THE APPLIANCE, at left), and
have a qualified service technician check the system.
Risk of explosion or fire causing burns or
death if safety interlocks are disabled. DO NOT attempt to
operate heater when SERVICE HEATER light is on or if
blower or burner will not start. Instead, follow instructions
under “To Turn Off Gas to the Appliance”, at left, and call
a qualified service technician to repair unit.
AFTER START-UP
CHECKING WATER FLOW
Fire or flooding hazard. If the unit overheats
and the burner fails to shut off, follow instructions under
“To Turn Off Gas to the Appliance”, Page 6, and call a
qualified service technician to repair unit.
After start-up, the outlet water pipe should feel slightly
warmer than the inlet pipe. If it feels hot, or if you hear the
water in the heater boiling, there may not be enough water
flow to the appliance. Make sure that the filter is not
plugged. If water temperature remains high but the unit
continues to operate, turn off the appliance and call your
service technician.
SPRING AND FALL OPERATION
If the pool is only used occasionally, lower the pool ther-
mostat to 65°F. and leave the heater on. This will keep the
pool and the surrounding ground warm enough so that the
heater should restore the pool to a comfortable tempera-
ture within about one day.
COLD WEATHER OPERATION
The heater may be operated in the wintertime, provided air
temperatures remain above freezing and the water tempera-
ture is not permitted to drop below 65°F. Extended heater
operation with water temperatures below 65°F can result in
serious damage to the heater and is not covered by warranty.
NOTICE: When starting the heater for the swimming sea-
son with a water temperature below 50°F, the heater may
be used to heat the water; however, make sure that the
heater operates continuously until the water temperature
reaches the heater’s minimum setting of 65°F.
During cold weather, if there is no danger of freezing,
operate the filter pump continuously even if the heater is
not operating. If air temperatures are expected to drop
below freezing (32°F), shut down the heater and winterize
it (See ”WINTERIZING”, Page 8). Allowing the heater to
freeze will void the warranty.
MAINTAINING POOL TEMPERATURE
To maintain pool temperature, make sure that the heater
switch and valving are reset to pool settings after using the
spa.
ENERGY SAVING TIPS
1. Keep the pool or spa covered when not in use. This
will reduce heating costs, reduce water evaporation,
conserve chemicals and reduce load on the filtering
system.
2. Reduce pool thermostat to 78°F or lower; reduce spa
temperature to 100°F.
3. Use a time clock to start the filter pump at 6 a.m. or
later. The swimming pool loses less heat after day-
break.
4. For pools used only on weekends, lower the thermostat
setting by 10°F to 15°F during the week to reduce heat
loss. A properly sized heater will restore normal tem-
perature within one day.
5. Turn the heater off when the pool will not be used for
an extended period.
6. Follow a regular program of preventive maintenance
for the heater each new swimming season. Check
operation of the heater and its controls.
