

It indicates a potentially dangerous

situation that, if not avoided, may

cause death or serious lesions.

CAUTION



It indicates a potentially dangerous

situation that, if not avoided, may

cause slight or moderate injury.

Also used to warn against unsafe

practices.

NOTE



It indicates situation that may

cause accidental damage to the

equipment or property.

water leaks, electric shock, fire or the unit falling from its

support.



Install the unit on a structure that can withstand its weight. An

insufficiently robust structure may lead to the unit falling

causing possible lesions.



Perform installation operations considering the possibility that

strong winds, hurricanes or earthquakes may occur. Incorrect

installation operations may lead to accidents caused by falling

equipment.



Make sure all electrical operations are performed by qualified

personnel in accordance with the law, local regulations and

this manual.



Connect the unit to a separate power supply circuit. An

insufficient capacity of the power supply circuit or incorrect

connections may lead to electric shock or fire.



Make sure to install an additional differential circuit-breaker

against a leakage to earth compliant with the law and local

regulations: omnipolar circuit breaker, at least 3 mm

separation in all poles, residual current device (RCD) with a

rated value not exceeding 30 mA.



Failing to install a differential circuit-breaker may lead to

electric shock and fire.



Make sure all the wiring is safe. Use the specified wires and

make sure terminal connections and wires are protected

against the water, external forces or other phenomena.

Incomplete connections or fixing may cause a fire.



When connecting the power supply, arrange the wires so that

the front panel can be fixed properly. If the front panel is not

in position, it may lead to terminals overheating, electric shock

or fire.



People working or intervening on a cooling circuit must hold a

suitable certification issued by an authorised assessment

centre proving their suitability to handle refrigerants safely in

compliance with a specific assessment recognised by industry

associations.



After installation operations are over, verify that there are no

refrigerant leaks.



Never touch the leaking refrigerant directly, as it may lead to

serious frostbite injuries. Do not touch the refrigerant pipes

during and right after functioning, as they may be hot or cold

depending on the conditions of the refrigerant flowing through

the pipes, compressor and other parts of the cooling circuit.

Burns or frostbite may occur if you touch the refrigerant

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.
