for the recovery of refrigerant).
Cylinders shall be complete with
pressure relief valve and associated
shutoff valves in good working order.
Empty recovery cylinders are evacuated
and, if possible, cooled before recovery
occurs. The recovery equipment shall
be in good working order with a set of
instructions concerning the equipment
that is at hand and shall be suitable for
the recovery of flammable refrigerants.
In addition, a set of calibrated weighing
scales shall be available and in good
working order. Hoses shall be complete
with leak-free disconnect couplings
and in good condition. Before using
the recovery machine, check that it
is in satisfactory working order, has
been properly maintained and that
any associated electrical components
are sealed to prevent ignition in
the event of a refrigerant release.
Consult manufacturer if in doubt.
The recovered refrigerant shall be
returned to the refrigerant supplier in
the correct recovery cylinder, and the
relevant Waste Transfer Note arranged.
Do not mix refrigerants in recovery
units and especially not in cylinders.
If compressors or compressor oils
are to be removed, ensure that they
have been evacuated to an acceptable
level to make certain that flammable
refrigerant does not remain within
the lubricant. The evacuation process
shall be carried out prior to returning
the compressor to the suppliers. Only
electric heating to the compressor
body shall be employed to accelerate
this process. When oil is drained
from a system, it shall be carried out
safely. When moving or relocating the
air conditioner, consult experienced
service technicians for disconnection
and reinstallation of the unit. Do not
place any other electrical products or
household belongings under indoor
unit or outdoor unit. Condensation
dripping from the unit might get
them wet, and may cause damage
or malfunction of your property. To
keep ventilation openings clear of
obstruction. The appliance shall be
stored in a well-ventilated area where
the room size corresponds to the room
area as specified for operation. The
appliance shall be stored in a room
without continuously operating open
flames (for example an operating gas
appliance) and ignition sources (for
example an operating electric heater).
Reusable mechanical connectors and
flared joints are not allowed.
