I. General product presentation and operating
BWT Inverter water/ air heat pumps are purpose designed to heat or coo swimming poo s. Performance data
is on y guaranteed for this specific app ication.
Water / air heat pumps are an efficient inexpensive means of heating swimming poo water.
The device exp oits the thermodynamic properties of heat transfer f uids when subjected to the we known
compression – expansion cyc e: owing to its specia properties, the refrigerant recovers ca ories from the
inexhaustib e supp y contained in ambient air, then, after compression and heating, transfers them to the
swimming poo water, thus heating it.
Given that a heat pump transfers heat extracted from outdoor air to the poo water, rather than creating heat
ike a boi er or e ectrica heater a heat pump heats the poo water for 80 % ess than the cost of heating by
other means.
Neverthe ess, in order to further reduce poo heating costs. the poo shou d be covered with an isotherma
cover at night and. more genera y. whi e the poo is not in use. The cover minimises evaporation from the
surface of the water the main source of heat oss.
Despite this, during the co der times of year, it may be necessary to run the heat pump continuous y 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 a ways cheaper than other conventiona heating means.
Un ike On/ Off heat pumps, Inverter heat pumps can modu ate their operating mode and adapt it to
the swimming poo ’s heating demand. This characteristic makes them even more economica than other
machines, a ows them to run more si ent y in temperature maintenance mode and increases the service ife
of critica components, notab y the compressor.

II. Safety recommandations
•Whi e the compressor is working. some elements of the refrigerant circuit
•may become very hot others very cold. Therefore, access to areas ocated
•being the machine’s pane s is restricted to qua ified professiona s.
•Never poke any object through the slots in the grating that protects the
impeller, this cou d damage the impe er.
•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 regu ations in effect in at the insta ation site - See the
recommendations set out in paragraph V.1 and V.3.
•To avoid any risk of danger damaged power cables must be rep aced immediate y by the manufacturer, its
after sa es service or simi ar y qua ified personne .
•Always cut the power supply to the device upstream before any intervention
requiring remova of the pane s or invo ving the hydrau ic connections.
•During storms, cut the power supply to the machine
•When instne in; to dismant e the machine, proceed in the reverse order.
