R290
Any intervention on the de-
vice, including disposal, must
be performed by qualified per-
sonnel with a suitable Refrig-
eration Technician's Licence
aimed at the knowledge and
management of systems con-
taining HC type gases such as
R290 (Propane).
During any routine or extraordinary maintenance or failure the
manufacturer recommends that maintenance personnel use a
suitable HC gas detector equipped with the necessary safety
devices to prevent ignition in the presence of a potentially ex-
plosive atmosphere.
Always ensure adequate ventilation of the installation compart-
ment before carrying out any work on the product, as the refrig-
erant gas used is odorless.
Maintenance personnel must therefore implement all the pro-
cedures and precautions necessary to prevent any dangerous
situation in the presence of a flammable gas.
The product does not have a charging or recharging valve, as
this operation cannot and must not be performed for any rea-
son on site. In case of a leak in the refrigeration circuit or if it
is partially or entirely empty, the maintenance technician must
have the entire system replaced.
During maintenance operations, the operator in charge must
check the following points.
Installation conditions
Check that:
• The dimensions of the installation compartment are those
specified in this manual.
• Sufficient ventilation of the room is ensured.
• The markings and graphic signs on the product are present
and legible.
• There are no signs of damage or corrosion on the product
that could impair its operation or cause refrigerant gas to
escape.
In case of differences in the product installation conditions,
maintenance personnel are required to inform the owner and
proceed with elimination of the non-conformities found.
Checks and repairs of electrical components
Check that:
• There are no conditions of imminent danger for the operator;
• The circuit is not powered.
• If it is not possible to operate without power supply, make
sure the owner has been notified regarding the situation.
• The electric capacitors have been safely discharged without
producing sparks.
• There is continuity in the ground connection.
• The electrical components are replaced only with original
spare parts.
• No cuts or joints are made on the cables of the electrical
components.
• The cables and wires do not have any damage which could
compromise the integrity of the product and the safety of
people and/or property.
Note: Only original replacement electrical components are
guaranteed by the manufacturer as safe and tested by a third
party for use with flammable refrigerants.
