MAINTENANCE
It is recommended that you check the following at least every six months and at the beginning of every
swimming season.
1. Make sure there are no obstructions to the flow of air to or from the appliance.
2. Examine the evaporator coil and fan grille. Check that debris such as leaves has not accumulated
on the inside or outside of the heater. If the evaporator coil is restricted, the heater will not
perform at optimum efficiency. The interior of the heater should be cleaned by a qualified service
technician.
3. Keep the heater area clear and free of combustibles and flammable liquids. Chlorine should not be
stored in the vicinity of the heater. Chlorine vapour, when drawn through a heater, can rapidly
cause corrosion of working parts and exterior panels.
4. Keep the heater area free from garden refuse and debris. This will help prevent insects nesting in
the unit and ensure extended life and reliability of your heater.
ENERGY SAVING TIPS
1. If possible, keep pool or spa covered when not in use. This will not only cut heating costs, but
will also keep dirt and debris from settling in the pool and conserve chemicals.
2. Reduce pool thermostat setting to 28C or lower. This is accepted as a comfortable and healthy
swimming temperature.
3. Use an accurate thermometer.
4. Set timeclock to start filtration and circulation system no earlier than daybreak. The pool loses
less heat at this time and the heat pump operates more efficiently during the warmer times of the
day.
5. If your filtration pump is large, consider installing a small pump for circulating water through the
heat pump.
6. For pools that are only used on weekends, it is not necessary to leave the thermostat set at normal
swimming temperature. During the week, lower it by an amount that can easily be achieved in
one day (generally 2C to 5C).
7. During the winter or while on vacation, turn the heater off.
8. Set up a regular program of preventative maintenance for the heater each new swimming season.
WINTER OPERATION
If the pool won’t be used for a month or more, turn the heater off at the main isolating switch. For areas
where there is no danger of freezing, water should circulate through your heater all year long even though
you are not heating your pool.
Where freezing is possible, it is necessary to drain the water from the heater. This may be done by
loosening the inlet or outlet barrel union. If the heater is below water level, isolate it from the pool first
by closing shut off valves before and after the heater.
CAUTION: If the heater has been drained for freezing conditions, do not turn on until the system is
circulating water.
