Start-Up Procedure; Daily Use Of The Heat Pump; Condensation - Harmopool ZVWX4013 Instructions Manual

Start-up procedure

Start-up Procedure - after the installation is completed, you should follow these steps:
1. Set the by-pass valve 1 entirely open. Turn on your filter pump. Check for water
leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit and turn the unit ON with the
switch. Slightly close valve 1 until the heat pump starts.
3. After running a few minutes, check if the air leaving the side of the unit is 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 (as long as your pool pump is running)
when the pool temperature drops more than 1 degree Celsius below set
temperature. Several days are needed to bring the temperature of your swimming
pool water to its required value.
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.

Daily use of the heat pump

The heat pump can be switched on an off via the on-off switch. The heat pump can also be
connected to the same power grid as your filtration pump, so that the heat pump is
switched on automatically as soon as the filtration pump is switched on.
It must be avoided that the heat pump receives electrical current when the filtration pump
is not being used. In this case, the heat pump will start, overheat and stop working due to
the high temperature protection. In the long term, this can cause damage to the heat
pump, which will not be covered by your warranty.
Under 12 degC, a low temperature alarm will stop the heat pump functioning to prevent
freezing of the heat pump.

Condensation

Since the heat pump cools down the air about 8 - 12 °C, 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.
