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 automa-
tically 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.
NOTE:
It’s recommended to be patience at startup and wait until the pool temperature natural-
ly reaches 15 degrees before starting up the heat pump. This will result in a rapid and
energy efficient heating of the pool water. The water will also be heated if the startup
temperature is below 8-15 degrees, but the heatingtime will be significantly longer and
the energy consumption will be higher.
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 interrup-
tion 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.
