If your installation is equipped of the water treatment with product adductions (e.g. chlorine,
brominates, salt…) the by-pass must be installed before the water treatment, with a non-return
valve between the by-pass and water treatment.
Electrical connection
Electrical supply must correspond to that indicated on the appliance.
Connection cables have to be sized according to appliance power and installation
requirements.
Please refer to below table:
These data are only indication, you must ask an electrician to determine the exact data for
your pool installation.
Use the cable glands and grommets provided inside the heat pump to route cables.
STARTING UP FOR THE FIRST TIME
After all the connections have been made and checked, the following steps must be taken:
1. Turn on the filter pump. Check for leaks and make certain that the water flows from and to
the swimming pool.
2. Connect the power supply to the heat pump and press the ON/OFF button. The appliance
will start up after the time delay (see below) has elapsed.
3. After a few minutes check whether the air being expelled from the appliance is cooler.
4. Leave the appliance and filter pump in operation 24 hours per day until the desired water
temperature has been reached. At this point the heat pump ceases operation. The appliance
will now start up again automatically (as long as the filter pump is in operation) whenever
the swimming pool temperature falls to 1 degree below the programmed temperature.
Depending on the initial temperature of the swimming pool water and the air temperature,
several days may be needed to bring the water up to the temperature required. Covering the
