2.5 Initial startup of the heat pump

The following steps need to be taken at startup (after verification that all the connections are made
according the specifications:
• Turn on the filter pump. Check for possible water leakage and water flow to and from the
swimming pool.
• Put the power plug into the outlet and switch the heat pump ON. The unit will start after the
time delay (see further).
• Verify after a few minutes that the air exhausted by the heat pump is becoming cooler.
• 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 va-
lue, depending on the initial water temperature and the ambient temperature. A good pool cover and
insulation of the piping can shorten this period considerably.
Attention: 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.

2.6 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.
Attention: A quick way to verify that the water running trough the drain is condensation
water is to shut off the unit and keep the pool pump running. If the water stops
running out of the base pan, it is condensation water. AN EVEN QUICKER WAY
- TEST THE DRAIN WATER FOR CHLORINE - if there is no chlorine present, then
it's condensation.

Usage and operation

3.1 The display

See page 28
The heat pump can be turned on or off with the ON/OFF button.
When OFF the display is showing the following information:
• The indication 'OFF' at the location of the pool water temperature
• The temperature wanted for heating
• Eventual error messages
When ON the display is showing the following information:
• The temperature wanted for heating
• The pool water temperature
• The indication 'Heating' when the unit is heating the water
• A graphical representation of the water flow: the flow bar (see further)
3.2 Setting of the desired temperature
The desired temperature can directly be set with the arrow keys. The setting will automatically be
stored in memory.
A choice can be made between °C and °F as follows:
• Cut electrical power to the unit
• Press both arrow keys at the same time and restore electrical power to the unit, than
release the keys.
