11.1 Residual risks
This paragraph sets forth any residual risks which cannot be eliminated by the manufacturer in the design stage.
Handling
There is always the risk of the unit falling or tipping over during handling. Follow the instructions in the
“Handling” section and take all of the precautions foreseen according to local regulations.
Installation
Unsuitable installation can cause water leaks, gas leaks, electric shocks, fire hazards, malfunctioning or
damage of the unit. Only qualified technical personnel can perform installation.
Place the unit in an appropriate area and without the risk of flammable gas leaks. Make the installation zone
inaccessible to third parties.
Dust/Water in the
electric panel
Fasten the panel of the electrical switchgear correctly. Any infiltrations can cause shocks and short-circuits
causing personal harm and damage to property or to the unit itself.
Pay special attention to the earthing connection.
Maintenance
During maintenance, which must always be carried out by authorised personnel, make sure that the
disconnector is off and
that no one can accidentally modify the disconnection measures of the appliance
from the unit by means of specific warnings and an adequate padlock.
Fan
Contact with the fan can cause injury and/or death. Do not access the unit or remove the protections while
the fan is running.
Refrigerant gas
leakage
Wear suitable PPE as a gas leakage could cause injury and intoxication. Carefully read the “Safety data sheet
of the refrigerant” included in the manual. Do not make use of heat sources near the circuit before it is
Water leaks
These can cause personal harm and property damage and risk a short circuit. We recommend positioning
the shut-off valves.
■ All personnel working on the refrigeration circuit must be able to present a certificate of competence, issued by an organization
with industrial accreditation. This certificate confirms, through industry standard procedures, their competence in the safe
management of refrigerants.
■ Maintenance operations can only be carried out in compliance with the manufacturer's specifications. If maintenance and repair
operations require assistance from additional personnel, the person qualified for the management of flammable refrigerants must
constantly supervise the work.
■ Before starting any operation on devices with flammable refrigerant, safety checks must be carried out in order to minimize the
risk of ignition. Take the following measures before working on the cooling circuit:
General working environment:
■ Inform the following people of the type of operation to be performed:
- All maintenance personnel
- All people in the vicinity of the plant.
■ Delimit the area around the heat pump.
■ Check for flammable materials and ignition sources in the immediate
vicinity of the heat pump:
Remove all flammable materials and sources of ignition.
■ In order to identify a flammable atmosphere in time:
Check before, during and after work, the presence of any leaks of
refrigerant in the surrounding area using a detector of refrigerant suitable
for R32 gas and explosion proof.
Said coolant detector must not generate sparks and must be properly
Fire extinguisher
A CO2 or powder extinguisher must be kept close at hand in cases where
:
The coolant is topped up.
Soldering or soldering / soldering / soldering operations are performed
