Safety instructions and precautions
EN
It is important to test the appliance’s installation circuit before and
after installing it to ensure that there are no gas leaks.
Gas must always be handled by a qualied gas professional. Never
attempt to repair the heat pump yourself.
• The appliance must be kept away from all ammable sources.
• In the event of a gas leak, switch o the appliance immediately
and contact your professional tter.
Soldering must only be carried
out by professionals in a repair
centre intended for such.
The appliance must be installed
outdoors in a ventilated area to
ensure good air circulation.
• The appliance must be installed by a professional. The user
must not make changes to the existing installation under any
circumstances.
• You must strictly follow the manufacturer’s guidelines when
servicing or filling gas. Please refer to the technical service
manual.
• Please avoid direct contact with the appliance’s air outlet and
protection grille.

Safety instructions and precautions
EN
• If you notice any abnormal conditions, such as a noise, smoke,
odour or an electrical leakage, immediately switch the appliance
off and contact your professional fitter.
• Do not use or store fuel or liquid gas such as thinners/solvents,
paint or petrol close to the appliance because it is a fire risk.
• To optimise the heating efficiency, insulate the hydraulic
connections between the swimming pool and the heat pump.
Use a suitable cover over your swimming pool.
• The hydraulic circuit between the swimming pool and the
appliance must be ≤10m otherwise heating efficiency may be
reduced.
• This appliance can reach a high efficiency level with an air
temperature between +10°C and +43°C.
• Avoid too high temperatures which would cause overheating or
too low, which would make water too cold.
• The appliance’s main power switch must be out of children’s
reach.
• If you experience a loss of power, the heat pump will automatically
reactivate once power is restored.
• Switch the appliance off during a power cut and reset the
temperature once the power is restored.
• In the event of a thunderstorm, switch off the main power switch
to avoid lightening damage.
• This appliance is not intended to be used by children or any person
with reduced physical, sensory or mental capacities, unless they
have been given supervision or instruction concerning use of the
device from a person responsible for their safety.
• If the appliance is not used for a long period of time, consider
unplugging it and draining it completely by opening the valve on
the inlet pipe.

Recommendations
EN
• Heat pump installation must be carried out by a qualified
professional.
• Adjust the temperature of the pool water to ensure that the
appliance operates effectively.
• Do not obstruct the air outlet to ensure optimal performance
and prevent it from becoming less effective.
• You can choose between different technical parameters
according to the user guide. However, this pool heat pump was
optimised at the factory.
• During transportation, it must be kept upright. Do not lift the
water connection. The titanium exchanger could become
damaged.
• Never plug in or use the appliance if it is damaged or defective.
• Please read carefully this manual before installing the appliance.
Strictly follow the instructions provided to ensure user safety
and avoid damaging the appliance.

Heat pump installation
EN
Location and dimensions
Securing the frame
The heat pump must be installed in a well-ventilated area on a firm,
flat surface. The appliance must always be kept upright, in a vertical
position.
To ensure heating efficiency, the water pipe between the swimming
pool and the heat pump must be between 2m and 10m.
You must leave a space of at least 50cm between the heat pump and
any obstacle (wall, bush, etc.).
The appliance’s frame must be secured with nuts (M10) to a concrete
base or with brackets. The concrete base must be solid and stable
and the brackets must be protected against rusting.

Ventilation
Auxiliary pump
Wiring
Do not obstruct ventilation. Incoming and outgoing air must be able
to circulate freely.
Keep a space of at least 50cm around the appliance otherwise the
machine’s efficiency could be reduced or even prevented.
The appliance needs to use an auxiliary pump (provided by the
manufacturer). To ensure the recommended pump flow rate, refer
to the technical parameters. Discharge head ≥10m.
Make sure the correct voltage is used to operate the appliance. Also
check that the appliance is correctly grounded. The wiring must be
undertaken by a professional technician and be in accordance with
the wiring diagram provided.
You must install a ground fault circuit interrupter in compliance
with the electrical installation legislation (leakage detecting current
≤ 30mA).
The power cable and interface cable must be installed in accordance
with current regulations and the cables must be connected
separately.

11
Heat pump installation
EN
During operation
It is normal to see condensate draining from the bottom of the
appliance. This is from the condensation from the water vapour in
the air when it goes into the exchanger. You must make sure water
can easily flow from of the pump.
Switching the pump on
After completing and checking the power cable installation, switch
the heat pump on. To use the appliance correctly, you must comply
with the following:
• Open the swimming pool pump, then open the heat pump
• Close the heat pump, then close the swimming pool pump.

Appliance test
ENEN
Check before use
Trial
You must check the appliance installation and hydraulic connections
referring to the installation diagrams. (See the “heat pump installation”
section on page 8). The wiring and grounding must also be checked.
(See the “power cable connection” section on page 12).
Ensure that the appliance’s main switch is on OFF and check the
temperature setting.
Check the ventilation device and outlets operate correctly and are
not obstructed.
Complete a airtightness check in a ventilated space. This control
must not be carried out in a closed space.
If you suspect a leak, stop using the heat pump and contact
NOVARDEN’s Customer Services.
It is normal to see condensate draining from the bottom of the
appliance. This is from the condensation from the water vapour in
the air when it goes into the exchanger. You must make sure water
can easily flow from of the pump.

16
Maintenance
EN
Risk of electric shock: switch the appliance off before carrying
out any maintenance on it.
During the winter season, when you do not use the swimming pool:
• Switch the appliance off to avoid damaging the machine.
• Drain all water from the machine.
• Cover the appliance with a tarpaulin to protect it from dust.
Important:
Unscrew the inlet pipe connection to let the water out.
If water remains in the appliance and freezes and the titanium
exchanger could be damaged.
Only clean the machine with household cleaning products or
clean water. Never use petrol-based products, thinners or similar
combustible products.
Regularly check the nuts, cables and connections.
Contact the Customer Services department if the appliance requires
an intervention or repairs. Never attempt to repair the appliance
yourself to avoid risk of personal injury.
The NOVARDEN warranty shall be null and void if you were to carry
out an intervention yourself.
