Pool Heat Pump _20
TROUBLESHOOTING
The digital display thermometer will not provide a reading:
The electrical breaker has tripped. Turn the electrical breaker back on.
The water flow rate is insufficient or the filter pump is not working.
DPL heat pumps are designed to operate with a minimum
water flow rate of 22.5 gallons per minute (GPM). Start the water pump.
If you are unable to activate the digital display thermostat, contact our Service Centre at +1.450.818.4758.
The digital display thermostat is active but the compressor and the ventilator(s) will not function:
> The unit is in 5-minute time delay mode to ensure that system pressures are stable. The “HEAT” pilot light will blink
during this 5-minute time delay.
> The temperature control is set at too low a numerical value. Raise the desired temperature level.
> The desired water temperature has been achieved and the unit will restart automatically when the water temperature
falls below the thermostat setting.
The digital display thermostat shows the codes E1, E2, HHH or LLL:
> The temperature sensor is not functioning normally.
> Contact our Service Centre at +1.450.818.4758.
The digital display thermostat lights up, dims out, lights up, dims out at irregular intervals:
> There is probably some kind of pump operation defect which can occur for many reasons:
> Excessively high refrigerant pressure
> Excessively high water temperature
> Loss of refrigerant
> Fan motor failure
> Evaporator freeze-up
> Low ambient temperature
> Coil obstruction (evaporator)
