„
In case of danger, switch off the electrical power and gas
supplies only if this can be done in total safety.
„
Do not entrust children, persons with physical, sensory
or mental disabilities or persons with poor knowledge
and experience with use of the appliance.
Gas component tightness
„
Before performing any operation on gas ducting compo-
nents, close the gas valve.
„
Upon completing any procedure, perform the tightness
test according to regulations in force.
Gas smell
If you smell gas:
„ Do not use electrical devices such as telephones, multi-
meters or other equipment that may cause sparks next
to the appliance.
„
Shut off the gas supply by turning the valve off.
„ Switch off the power supply via the external disconnect
switch in the power supply electrical panel.
„
Use a telephone away from the appliance to ask for inter-
vention from qualified personnel.
Poisoning
„
Ensure the flue gas ducts are tightness and compliant
with the regulations in force.
„ Upon completing any procedure, ensure the tightness of
the components.
Moving parts
The appliance contains moving parts.
„
Do not remove guards during operation, and in any case
prior to disconnecting the power supply.
Burn hazard
The appliance contains very hot parts.
„
Do not open the appliance and do not touch internal
components before the appliance has cooled down.
„
Do not touch the flue gas exhaust before it has cooled
down.
Pressure vessels
The appliance has a sealed circuit classified as pres-
sure vessel, the tightness of which is tested by the
manufacturer.
„
Do not carry out any intervention on the sealed circuit or
on the appliance's valves.
Water-ammonia solution
The GAHP unit uses the ammonia-water absorption
cycle. The water-ammonia solution is contained in the
sealed circuit. The solution is harmful for health if it is in-
gested, inhaled or comes in contact with the skin.
„
In the event of coolant leak keep away and disconnect
the power and gas supply (only if it is possible to do so
with no danger).
„
It is recommended that no work be performed on the
sealed circuit except by a qualified service technician
or engineer .
„
Care should be taken not to disturb or handle the valves
of the sealed circuit.
Electrocution hazard
„
Disconnect the electrical power supply before any op-
eration on appliance components.
„
For electrical connections exclusively use compliant
components and according to the specifications pro-
vided by the manufacturer.
„
Ensure the appliance cannot be accidentally switched
back on.
Grounding
Electrical safety depends on effective grounding system,
correctly connected to the appliance and installed ac-
cording to the regulations in force.
Distance from combustible or flammable materials
„ Do not deposit flammable materials (paper, diluents,
paints, etc.) near the appliance.
Limescale and corrosion
Depending on the chemical/physical properties of the
system water, limescale or corrosion may damage the
appliance (Paragraph 3.7
p. 22).
„ Check system sealing.
„
Avoid frequent top-ups.
Chloride concentration
The concentration of chlorides or free chlorine in the
system water must not exceed the values in Table
3.2 p. 22.
Aggressive substances in the air
Halogenated hydrocarbons containing chlorine and flu-
orine compounds cause corrosion. The air of the installa-
tion site must be free from aggressive substances.
Switching the appliance off
Disconnecting the power supply while the appliance
is running may cause permanent damage to internal
components.
„
Except in the case of danger, do not disconnect the pow-
er supply to switch off the appliance, but always and ex-
