2. Instructions for repairing appliances containing
R290
heaters.
Information about the different safety concepts:
Unventilated – (see Clause GG.2) Safety of the
appliance does not depend on ventilation of the
housing. Switching off the appliance or opening
of the housing has no significant effect on the
safety. Nevertheless, it is possible that leaking
refrigerant may accumulate inside the enclosure
and flammable atmosphere will be released when
the enclosure is opened.
Ventilated enclosure – (see Clause GG.4) Safety
of the appliance depends on ventilation of the
housing. Switching off the appliance or opening
of the enclosure has a significant effect on
the safety. Care should be taken to ensure a
sufficient ventilation before.
Ventilated room – (see Clause GG.5) Safety of the
appliance depends on the ventilation of the room.
Switching off the appliance or opening of the
housing has no significant effect on the safety.
The ventilation of the room shall not be switched
off during repair procedures.
Information about the concept of sealed
components and sealed enclosures according to
IEC 60079-15:2010.
Information about the correct working
procedures:
a) Commissioning
• Ensure that the floor area is sufficient
for the refrigerant charge or that the
ventilation duct is assembled in a correct
manner.
• Connect the pipes and carry out a leak test
before charging with refrigerant.
• Check safety equipment before putting
into service.
b) Maintenance
Local air-conditioner / User Manual
• Portable equipment shall be repaired
outside or in a workshop specially equipped
for servicing units with flammable
refrigerants.
• Ensure sufficient ventilation at the repair
place.
• Be aware that malfunction of the
equipment may be caused by refrigerant
loss and a refrigerant leak is possible.
• Discharge capacitors in a way that won't
cause any spark. The standard procedure to
short circuit the capacitor terminals usually
creates sparks.
• Reassemble sealed enclosures accurately.
If seals are worn, replace them.
• Check safety equipment before putting
into service.
c) Repair
• Portable equipment shall be repaired
outside or in a workshop specially equipped
for servicing units with flammable
refrigerants.
• Ensure sufficient ventilation at the repair
place.
• Be aware that malfunction of the
equipment may be caused by refrigerant
loss and a refrigerant leak is possible.
• Discharge capacitors in a way that won't
cause any spark.
• When brazing is required, the following
procedures shall be carried out in the right
order:
– Remove the refrigerant. If the recovery is
not required by national regulations, drain
the refrigerant to the outside. Take care
that the drained refrigerant will not cause
