I. General product presentation and operating
BWT Inverter water/ air heat pumps are purpose designed to heat or cool swimming pools. Performance data
is only guaranteed for this specific application.
Water / air heat pumps are an efficient inexpensive means of heating swimming pool water.
The device exploits the thermodynamic properties of heat transfer fluids when subjected to the well known
compression – expansion cycle: owing to its special properties, the refrigerant recovers calories from the
inexhaustible supply contained in ambient air, then, after compression and heating, transfers them to the
swimming pool water, thus heating it.
Given that a heat pump transfers heat extracted from outdoor air to the pool water, rather than creating heat
like a boiler or electrical heater a heat pump heats the pool water for 80 % less than the cost of heating by
other means.
Nevertheless, in order to further reduce pool heating costs. the pool should be covered with an isothermal
cover at night and. more generally. while the pool is not in use. The cover minimises evaporation from the
surface of the water the main source of heat loss.
Despite this, during the colder times of year, it may be necessary to run the heat pump continuously 24 hours
a day. This is not a cause for concern; heat pumps are designed to run 24 hours a day. Even under these
circumstances a heat pump is always cheaper than other conventional heating means.
Unlike On/ Off heat pumps, Inverter heat pumps can modulate their operating mode and adapt it to
the swimming pool's heating demand. This characteristic makes them even more economical than other
machines, allows them to run more silently in temperature maintenance mode and increases the service life
of critical components, notably the compressor.

II. Safety recommandations

While the compressor is working. some elements of the refrigerant circuit

may become very hot others very cold. Therefore, access to areas located

being the machine's panels is restricted to qualified professionals.

Never poke any object through the slots in the grating that protects the
impeller, this could damage the impeller.

Never operate the machine while the impeller's protective grating is not
in position.

The distance separating the heat pump and its electrical panel from the water area should be determined
by a qualified professional in accordance with the regulations in effect in at the installation site - See the
recommendations set out in paragraph V.1 and V.3.

To avoid any risk of danger damaged power cables must be replaced immediately by the manufacturer, its
after sales service or similarly qualified personnel.

Always cut the power supply to the device upstream before any intervention
requiring removal of the panels or involving the hydraulic connections.

During storms, cut the power supply to the machine

When instne in; to dismantle the machine, proceed in the reverse order.
