Regulations

H What to do if refrigerant leaks
If refrigerant leaks and touches the skin, it can cause
frostbite.
▶ In case of a refrigerant leak, never touch any
components of the air to water system.
▶ Avoid skin or eye contact with refrigerant.
▶ Seek medical attention if you get refrigerant on your
skin or in your eyes.
H Handover to the user
When handing over, instruct the user how to operate
the heating system and inform the user about its
operating conditions.
▶ Explain how to operate the heating system and draw
the user's attention to any safety relevant action.
▶ In particular, point out the following:
– Modifications and repairs must only be carried
out by an approved contractor.
– Safe and environmentally compatible operation
requires inspection at least once a year and
proper cleaning and maintenance.

Refrigerant

1.2.1
H Refrigerant R32
▶ This appliance is filled with refrigerant R32. If
refrigerant gas gets into contact with fire, it may
generate a toxic gas or fire.
▶ Do not let any other substance than the specified
refrigerant enter the refrigerant circuit.
▶ Ensure that the refrigerant pipe is connected before
running the compressor.
▶ Be aware that refrigerant may not contain any
odour.
▶ Read all safety instructions for handling flammable
refrigerants provided with this appliance in a
separate document.
H Installation, commissioning and service
▶ Do not smoke and make sure that any other possible
ignition sources are kept way from the working area.
Ensure that the installation area is adequately
ventilated.
▶ Do not pierce or burn.
4
▶ This appliance must be stored in a room without
continuously operating ignition sources (e.g. open
flames, operating gas or operating electric heater).
▶ Prior and during installation, make sure that there
are no refrigerant leaks using an appropriate
refrigerant detector that is adequately sealed and
intrinsically safe (i.e. no sparking). Never use
potential sources of ignition to search for
refrigerant leaks. A halide torch (or any other
detector using a naked flame) may not be used. If a
refrigerant leak is detected, ventilate the room
immediately.
▶ When performing any hot work, dry powder or CO
fire extinguisher should be kept ready.
▶ Wear protective gloves during installation.
▶ Do not use means to accelerate the defrosting
process or to clean the appliance, other than those
recommended by the manufacturer.
H Maintenance
▶ When changing electrical components assure that
these correspond with the correct specification.
Maintenance and service guidelines must always be
followed.
▶ Before any repair and maintenance procedure, an
initial safety check and component inspection
procedures should be performed to check that:
– Capacitors are discharged.
– All electrical components are switched off and
wiring is not exposed.
– Earth bonding continuity is ensured.
▶ Do not connect any electrical supply to the circuit if
a fault that can compromise safety is detected.
