ECO+ series swimming pool heat pumps
3.7 Initial startup of the unit
The following steps need to be taken at startup (after verification that all the connections are made
according the specifications:
1.
Turn on the filter pump. Check for possible water leakage and water flow to and from the
swimming pool.
2.
Put the power plug into the outlet and switch the heat pump ON. The unit will start after the time
delay (see further).
3.
Verify after a few minutes that the air exhausted by the heat pump is becoming cooler.
4.
Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is
reached. When the set temperature is reached, the unit just shuts off. The unit will now
automatically restart when the pool temperature drops 1 degree Celsius below set temperature.
Several days will be needed to bring the temperature of the swimming pool water to its required value,
depending on the initial water temperature and the ambient temperature. A good pool cover and
insulation of the piping can shorten this period considerably.
Time delay
–
the unit is equipped with a 3-minute built-in delay to protect control circuit components
and to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit
approximately 3 minutes after each circuit interruption. Even a brief power interruption will activate
this delay and prevent the unit from starting until the 3-minute countdown is completed.
3.8 Condensation
By its operation of heating the swimming pool water, the air taken by the unit is cooled down and
water may condense on the fins of the evaporator. If the relative humidity is very high, this could be as
much as several liters an hour. Sometimes this condensation water is wrongly considered as swimming
pool water.
