SAFETY INSTRUCTIONS
• Store away from oxidizing gases and other oxidizing materials.
• The outdoor unit shall be stored in a space(especially safety
zone) without continuously operating open flames (for example
an operating gas appliance) and ignition sources (for example an
operating electric heater).
• Servicing shall only be performed as recommended by the
equipment manufacturer. Maintenance and repair requiring the
assistance of other skilled personnel shall be carried out under
the supervision of the person competent in the use of flammable
refrigerants.
• When mechanical connectors are reused, sealing parts shall be
renewed. When flared joints are reused the flare part shall be re-
fabricated.
• Periodic(more than once/year) cleaning of the dust or salt
particles stuck on the heat exchangers by using water.
• Keep any required ventilation openings clear of obstruction.
• Ensure that the area is in the open or that it is adequately
ventilated before breaking into the system or conducting any hot
work. A degree of ventilation shall continue during the period
that the work is carried out. The ventilation should safely
disperse any released refrigerant and preferably expel it
externally into the atmosphere.
• Cabling will not be subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse
environmental effects. The check shall also take into account the
effects of ageing or continual vibration from sources such as
compressors or fans.
• Under no circumstances shall potential sources of ignition be
used in the searching for or detection of refrigerant leaks. A
halide torch (or any other detector using a naked flame) shall not
be used.
