Introduction
Congratulations for buying a reversible heat pump for your swimming
pool.
This machine was installed in accordance with the current norms and
it is now ready to be used.
In order that you might be fully satisfied with this machine, you’ll find
below a few remarks :
- The Heat pump heats the swimming pool water only if the
filtration pump is working.
- At the beginning of the season or when the outside
temperature is low, you must increase the daily filtration time so
that the Heat pump can overcome thermal losses of the
swimming pool which are more important at that period.
- An isothermic cover is strongly advised.
- Finally we would like to draw your attention to the fact that to
expect a period of freezing, you must carry out the wintering of the
heat pump, or make your filtration work 24h/24.
Please read completely this manual.

Safety Instructions
Never cover (risk of overheating). Keep out of reach of children, and do not to let
them play nearby, inform them of the dangers of this machine.
Never introduce a stick or your fingers into the protective grille of the ventilation.
Never clean the machine with the water jet.
Never disconnect the machine when it’s working ; for any intervention even of
cleaning, stop the machine, by pressing first on the key OFF; in the event of an
emergency, cut off the current to the unit.
Principle of working

The Heat pump uses the free heat contained in the outside air to
transmit it to the swimming pool water.
The ventilator located in the heat pump has the air circulated on the
radiator with gilds.
When the Heat pump heats the swimming pool, the air blown is fresher
than the outside air.
In the contrary, when the heat pump cools the swimming pool, the air
blown is heater that the outside air.
You can regulate the temperature to which you want to heat your
swimming pool.
Careful : Increase the required temperature does not increase the
heating power (example: your swimming pool is at 18°C; if you want
28°C, don’t post 35°C to reach more quickly 28°C).
Using when it’s cold
Outside temperatures lower than 7°C.
When the outside temperature decreases and that the air becomes
wet, you might observe a thin layer of white frost on the gilds of the
radiator. This is normal (*).
To avoid a strong thickness of white frost which would prevent the air
to circulate through the gilds of the radiator, the Heat pump launches
regularly and automatically an operation of defrosting which is
accompanied with the stopping of the compressor during a few
minutes.
In addition the Heat pump is regulated in factory to stop as soon as the
outside temperature becomes lower than 7°C, to start again at 12°C.
You can choose your own adjustments for the two temperatures (if you
want to heat your swimming pool late in the season), by using the
procedure described at the paragraph “Adjustments”, or by calling
your retailer.
(*) the fluid which circulates in the Heat pump thanks to a compressor, is, at the
time of the passage in this radiator at an high negative temperature (same principle
used in your freezer).
Checking before and after starting

Before starting:
Your machine is tested and regulated in factory, however it is advised
to carry out the following controls before starting :
- electric connections correctly carried out
- installation carried out according to our
recommendations
- correct connection of arrival and exit water pipes
according to the written indications
(For more details on the rules of establishments refer to the
document: Of INSTALLATION AND MAINTENANCE)
- no foreign things on the machine or fixed on the gilds of
the radiator
After starting: Ensure that operation
is regular; if high vibrations occur, stop the Heat pump and call your
fitter.
Instructions
Careful :
The first pressure on the key ON/OFF gives the authorization of
starting the Heat pump; the latter will start within a variable time:
shortest within 1 second and longest within 4 minutes.
From its starting the heat pump heats or cools the swimming pool
water, and will automatically stop when the required temperature has
been reached; don’t stop its operation unnecessarily.
If you have to stop the Heat pump operation (for example to pass
from the heating mode to the cooling mode), you will observe that the
Heat pump will start again after 4 minutes.

8 - Regular operations of maintenance
Washing the sand filter of your filtration installation :
Stop the Heat pump
W
intering :
Stop and put the heat pump out of tension
Stop and put the filtration pump out of tension
Close the 2 isolating valves nearest of the Heat pump
Entirely unscrew the 2 connections on the Heat pump and have
each pipe slip to make leave the openings coming out from the heat
pump ; the Heat pump gets empty, wait for the complete emptying.
(THE EXCHANGER MIGHT BURST IF IT HAS NOT EMPTIED
COMPLETEY)
Put back each pipe to its place and screw again the connections to
entirely close again (to avoid little animal’s entry ) Remark :
supplement the draining of your filtration installation or call your
fitter (all your installation must be protected against the freezing)
Maintenance :
Make sure that nothing comes to block the gilds radiator, if it’s
necessary clean it with a soft brush (no water jet under pressure)
Make sure that the gilds are right, rectilinear, if it’s necessary
rectify them with a fine comb
Make sure that the flue of the condensates is not blocked

10-Problems / solutions :
The difficulties met the most often can be solved by reading the table below.
If nothing corresponds to the list, or if the solutions applied do not solve the problem, refer to DIRECTIONS FOR
INSTALLATION AND MAINTENANCE or contact your retailer.
Difficulty Observation Probable cause Explanation / Solution
Extinct screen No power Check that the circuit breaker
of the table is engaged in the
technical room
Extinct screen and heat
pump supplied in power The power supply is
defective Call your retailer
Extinct screen, filtration is
working
The in and out pipes of the
heat pump are reversed or
the flow switch is not
sufficient
Check on the heat pump that
the in and out pipes are not
reversed. Check the filtration
pump works or is not defused
The heat pump does
not start
Normal, lit screen The ambient temperature
has decreased below 5°C The heat pump will start again above 7°C
Water is running
below the heat pump The water comes from the bottom of the heat pump
Drain of the condensates
not installed or stopped :
black, plastic conduit
prolonged with a flexible
pipe of evacuation
It’s natural : these condensates
are caused by condensation of
the humid air on the gilds of
the evaporator
The heat pump works
The rising in temperature is more or less rapid according to
the volume of the swimming pool and to the climatic
conditions. An isothermic cover will improve the
performances in heating
The temperature of
the swimming pool is
increasing very slowly
The layer of the white frost
is thin The outside temperature is low and the air is humid See the paragrah 5 of this manuel
White frost or ice
appears outside on the
gilds of the evaporator
The layer of the white frost
is thick (the blades of the
ventilator may rub on the
ice much thicker inside)
Outside temperature very
low and air very humid
The automatic de-icing is not
sufficient ; stop the heat pump
for the operations of wintering
The heat pump emits
noises of vibration or
sheet
It’s not horizontal or not
well fixed ; the pipes may
have moved into the pump
during the transport or
the installation
The vibrations can be
located or the heat pump is
not stable Call your retailer
