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
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.
