TROUBLESHOOTING
DPL heat pumps are equipped with safeguards that will stop operation to protect your unit in certain situations:
High pressure switch
The high pressure circuit breaker protects the compressor in the event of any over-pressure in the refrigerant system.
High pressure conditions are usually the result of insufficient water flow in the heat exchanger. To remedy the situation,
simply check that there are no obstruction in the water supply circuit and/or clean out the filter system.
Low pressure switch
The low pressure circuit breaker protects the compressor in the event of frequent restarts that are due to a lack of
refrigerant or to an excessively low ambient temperature. It prevents the heat pump from starting when the system is in
a low pressure situation, i.e. below 36 PSI. Such a low pressure situation is usually the result of a refrigerant leak or of an
ambient temperature below 10 °C. The presence of frost on the evaporator can signal a low pressure situation.
Water pressure switch
The water pressure switch contacts close when pressure is applied as pool water flows through the heat exchanger. Either
no flow or low flow rates will cause the contacts to open and the unit will shut down.
Time delay
All models use a 5-minute time delay to prevent repeated tripping of the compressor thermal overload, which is caused
by an attempted startup before system pressures have equalized. Any interruptions, outside of power loss, will result in a
5-minute time delay.
