pipes. If it is necessary to touch the pipes,
wait for them to return to a normal
temperature or wear protective gloves and
clothes.
Do not touch the internal parts (pump, backup
heater, etc.) during and immediately after
functioning. Touching internal parts may cause
burns. To avoid lesions, wait until the internal
parts have returned to a normal temperature
or, if touching them is necessary, wear
protective gloves.
Do not use other means than those
recommended by the manufacturer to hasten
the defrosting or cleaning process.
The equipment must be placed somewhere
without continuous ignition sources (e.g. open
flame, a gas-operated device or an electric
heater).
Do not pierce nor burn.
Be aware that refrigerants are odourless.

Place the unit on the ground.
The earth resistance should comply with the
law and local regulations.
Do not connect the earth cable to gas or
water mains, lightning rods or phone earth
cables.
Incomplete earthing may cause electrical
shocks.
•
Gas mains: fires or explosions may occur in case
of a gas leak.
•
Water mains: rigid vinyl tubes are not effective.
•
Lightning rods or phone earth cables: the
electrical threshold can increase abnormally if hit
by lightning.
Install the power supply cable at least one
metre from TVs or radios to prevent
interferences or disturbances. Depending on
the type of radio wave, one metre may not be
enough to avoid disturbances.
Do not wash the unit as it may cause electric
shocks or fires.
If the power supply cable is damaged, it must
be replaced by the producers, personnel from
its assistance network or qualified personnel.
Do not install the unit in the following places:
•
Where there is mineral oil, even in form of vapour.
Plastic parts may deteriorate, disperse and cause
water leaks.
•
Where corrosive gases (such as sulphurous acid)
are produced.
•
Where the corrosion of copper pipes or welded
parts may cause refrigerant leaks.
•
Where there are devices emitting electromagnetic
waves. Electromagnetic waves may disturb the
control system and cause malfunctions.
•
Where flammable gases may leak, or carbon fibre
or flammable powers may be found in the air or
where volatile flammable materials such as paint
thinners or petrol are handled. These gases may
cause a fire.
•
Where the air contains high levels of salt, such as
the seaside.
•
Where the power supply voltage is subject to
fluctuations, such as in factories.
•
On vehicles or ships.
•
Where there are acid or alkaline vapours.
Prior to installation, verify if the user
’
s power
supply meets the unit
’
s installation
requirements (including reliable earthing,
differential circuit-breaker, component size, wire
section, etc.). If the electrical installation
requirements are not met, the unit cannot be
installed until the electrical system is rectified.
Before the hydraulic connection and electrical
wiring operations, verify that the installation
area is safe and without hidden dangers such
as water, electricity and gas conduits.
Do not touch the fins of the heat exchanger
as they may cause injury.
If installing multiple units in a centralised
manner, adjust the electric load on the various
phases. Do not connect multiple units to the
same phase of the three-phase supply.
The following subjects may use the unit if
supervised or instructed on safe usage and
