IX.Troubleshooting
REMARK: Do not repair or disassemble the air conditioning by
yourself. Unqualified repair will lead to failure of the
warranty card, and may cause damage to users or their properties.
1. Information on servicing
• Checks to the area
Prior to beginning work on systems containing flammable
refrigerants, safety checks are necessary to ensure that the risk
of ignition is minimised. For repair to the refrigerating system,
the following precautions shall be complied with prior to
conducting work on the system.
• Work procedure
Work shall be undertaken under a controlled procedure so as to
minimise the risk of a flammable gas or vapour being present
while the work is being performed.
• General work area
All maintenance staff and others working in the local area shall
be instructed on the nature of work being carried out. Work in
confined spaces shall be avoided. The area around the
workspace shall be sectioned off. Ensure that the conditions
within the area have been made safe by control of flammable
material.
• Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant
detector prior to and during work, to ensure the technician is
aware of potentially flammable atmospheres. Ensure that the
leak detection equipment being used is suitable for use with
flammable refrigerants, i.e. non-sparking, adequately sealed or
intrinsically safe.
• Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration
equipment or any associated parts, appropriate fire
extinguishing equipment shall be available to hand. Have a dry
powder or CO2 fire extinguisher adjacent to the charging area.
• No ignition sources
No person carrying out work in relation to a refrigeration system
which involves exposing any pipe work that contains or has
contained flammable refrigerant shall use any sources of
ignition in such a manner that it may lead to the risk of fire or
explosion. All possible ignition sources, including cigarette
smoking, should be kept sufficiently far away from the site of
installation, repairing, removing and disposal, during which
flammable refrigerant can possibly be released to the
