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.

Nota bene:technical data and dimensions may be subject to modification, without notification, over timedue to
product improvements. For more detail, refer to the information plate on the machine.
When the weather is co d and damp, frost can bui d up on the evaporator fins. This phenomenon is not theresu t of a
ma function; the frost wi be e iminated by automatic triggering of the thermodynamic defrostingcyc e (inversion of
the refrigerant cyc e). Once the frost has been me ted, the machine wi revert to norma operating mode.
The heat pump is fitted with a f ow contro er that on y a ows the machine to start up when the water f owrate
through the machine is adequate (see the recommended va ues in the technica data tab e).
V. Product installation
V.1) Siting
The fo owing points must be taken into consideration:
•The device must be installed outdoors
•Condensate drainage
Connect the e bows and the condensate drainage hose to the ho e in the machine f oor such that the
condensates wi be channe ed to waste. Do not mix condensates with the poo water.
•Distance from the water area
The distance must satisfy the stipulations of the local regulations
if effect at the installation site. However, this distance shou d not
be so great that the ength of the pipes makes it impossib e to
achieve the minimum water f ow rate necessary for correct
operation of the machine.
•Clearance
The minimum recommended c earances between each surface of
the machine and the nearest obstac e (wa , partition, hedge, etc.)
are shown as indicated :
The machine shou d not be ocated in a corner where air
circu ation and renewa cou d be hindered.

31 /76
2019/11– C - Code : 33260
Pay attention to the proximity of deciduous vegetation. Leaves, f owers, po en, etc. cou d be drawn in by the
fans and obstruct the gratings.
•Proximity to neighbours
Quite apart from the heat pump’s intrinsic acoustic eve , (measured in a aboratory according to
standardized methods and on standardised insta ations) the insta er is responsib e for ensuring that the
insta ation site wi not cause a phonic nuisance to neighbours, and take any necessary steps.
Refer toany oca ru es that app y.
•Soil moisture
The heat pump must not be insta ed in a ocation where precipitation can accumu ate and gather in
pudd es around the machine.
Condensates generated by the heat pump whi e it is running must be drained away (use the drain
connectionenc osed), and must not accumu ate around the machine.
•/30
•Installation height
If the machine is wa mounted, the intrinsic strength of the wa and the mounting must be sized, with
asafety margin, to bear the weight of the machine when fi ed with water. Take exposure to prevai ing
windsinto consideration. Mounting brackets must be treated against corrosion. Piping must be attached to
the wa to be supported (but not by the machine).
Make sure the fi tration pump can overcome the height difference between the fi tration pump and the
heatpump. Take any necessary steps (increase pump power, additiona pump, etc.).
V.2) Support
The heat pump must be attached by its feet to a so id, stab e and horizonta base (stain ess stee M
10screws). A s oped position cou d interfere with the f ow of condensates.
In the interest of noise abatement, the machine and pipes connected to it must be insta ed in such a waythat
they do not vibrate whi e running.
V.3) Handling
Never ift the machine by its hydrau ic unions.
Do not store the machine ying on its side. If the machine was aid on its side,
put it upright after storage,
and eave it stand ike this, switched off, for at
east 48 hours.
V.4) Connection to the hydraulic circuit
The heat pump must be mounted on a
fi tration circuit by-pass, downstream from
the sand fi ter, andupstream from the
injection of any treatment chemica s (the
titanium condenser is resistant to di ute poo
chemica s, but is not guaranteed against
exposure to high concentrations of poo
chemica s).
The bypass oop must be fitted with three
va ves, one on the bypass intake, one on the
bypass out et(iso ation va ves) and one
between the two tapping points (va ve to

32 /76
2019/11– C - Code : 33260
contro the f ow rate through the heat pump).
To imit heat oss from the pipes, bury them underground (at a depth of 50 to 80 cm depending on the
region) or ag the pipes. In any case, minimize the amount of uninsu ated pipe exposed to the air.
V.5) Wiring
The machine must be wired in by a qua ified professiona , after the hydrau ic connections have been
comp eted. When dismant ing the machine, disconnect it e ectrica y before disconnected the hydrau ic
connections.The heat pump’s power cab e connection termina is ocated behind the socket. Use a cab e with a
wirecross section that comp ies with the specification be ow, connected upstream to a breaking device rated
as set out in this tab e.

V.6) Heating priority :
It is possib e to set the system up so that the heat pump wi start up fi tration outside programmed
fi tration cyc es if a heating demand is detected. This a ows the poo water temperature to be he d more
constant y around the set point.
In this case, the heat pump wi start the fi tration up every our (un ess it is a ready running) to measure
the poo water temperature. If a heating demand is detected, it keeps the fi tration pump running,
otherwise it stops the fi tration pump after 3 minutes.
To do this, the e ectrica connections to be made wi use the termina s marked P1 and P2 on the heat
pump termina b ock:
Next, activate heating priority as fo ows on the contro pane :
•Press the and icons simu taneous y for 5 seconds to access the parametermodification menu.
•The “P0” parameter fo owed by “0” is disp ayed on the screen: “P0 0”.
•Press to modify P0, then press to scro unti 1 is disp ayed : “P0 1”
•Press once again to confirm,
•Press to exit the parameter modification menu.
To eave the heating priority mode, set the P0 parameter back to 0 fo owing the above procedure.
!IMPORTANT : do not modify the value of parameters other than P0

VIII. pkeep and maintenance
Check the evaporator fins regu ar y for debris ( eaves, f owers, po en, etc.), c ean the fins with a soft brushand soapy
water or with ordinary detergents. Do not use so vants.Check the condensate drainage tubes for obstructions
(water f owing around the machine).The machine cabinet may be c eaned with soapy water or ordinary detergent.
Do not use so vants.
VII.1) Shut down for winterizing:
If fi tration is shut down to winterize the poo , or if the water is not heated during active winterization:
• Cut e ectrica power to the machine (therma magnetic circuit breaker set to off).
• C ose the 2 iso ation va ves on the heat pump bypass oop.
• Unscrew the 2 hydrau ic unions to drain a water from the machine, and then cover these with the
caps provided (to avoid any unwanted guests taking up residence over the winter period).
• Cover the machine, if possib e, to prevent dirt from bui ding up on the externa parts.
VII.2) – Technical inspections:
The insta ation shou d be inspected once a year by a technician qua ified to hand e refrigerants.
Check that e ectrica and hydrau ic connections are correct y tightened.
Depending on the mass of refrigerant inside the machine, regu ations may require that the refrigerant circuit be
regu ar y inspected for eaks. Refer to the oca regu ation on that topic. The inspection certificate must be kept.
VII.3) – Spare parts:
Spare parts specific to BWT heat pumps, and essentia for them to run correct y, wi be avai ab e for at east 5 years
after the date of purchase of the machine (minimum duration in the event that the product is withdrawn from the
market).
IX. Error messages
Some errors do not cause the compressor to stop, but are disp ayed on screen (some wi a so generate an aura
a arm) for 3 minutes every 30 minutes unti either the prob em is reso ved, or the machine is stopped using the On/
Off button.
Other more critica errors wi stop the compressor. The power supp y to the machine must be disconnected before
proceeding with the repair. Upon restarting the machine, the error is reset and on y reappears if the prob em has
not been reso ved. Error messages associated with abnorma operating conditions are shown in bo d in the fo owing
tab e.
