f
When transferring refrigerant into cylinders, make sure that only the refrigerant recovery cylinders are used.
f
All cylinders used for the recovered refrigerant shall be labelled.
f
Cylinders shall be equipped with pressure relief valves and shut-off valves in a proper order.
f
The recovery system shall operate normally according to the specified instructions and shall be suitable for refrigerant recovery.
f
In addition, the calibration scales shall operate normally.
f
Hoses shall be equipped with leak-free disconnect couplings.
f
Before starting the recovery, check for the status of the recovery system and sealing state. Consult with the manufacturer if suspected.
f
The recovered refrigerant shall be returned to the supplier in the correct recovery cylinders with the Waste Transfer Note attached.
f
Do not mix refrigerants in the recovery units or cylinders.
f
If compressors or compressor oils are to be removed, make sure that they have been evacuated to the acceptable level to ensure
that flammable refrigerant does not remain in the lubricant.
f
The evacuation process shall be performed before sending the compressor to the suppliers.
f
Only the electrical heating to the compressor body is allowed to accelerate the process.
f
Oil shall be drained safely from the system.
f
Never install a motor-driven equipment to prevent ignition.
f
Empty recovery cylinders shall be evacuated and cooled before recovery.
Installation location requirements
f
The outdoor unit shall be installed in an open space that is always ventilated.
f
The local gas regulations shall be observed.
f
For installation inside a building (this applies either to indoor or outdoor units installed inside) a minimum room floor area of
space conditioned is mandatory according to IEC 60335-2-40:2018 (see the reference table into either the indoor or outdoor
unit installation manual).
f
To handle, purge, and dispose the refrigerant, or break into the refrigerant circuit, the worker should have a certificate from an
industry-accredited authority.
Moving the Outdoor Unit by Wire Rope
Fasten the outdoor unit by two 8 m or longer wire ropes as shown at the
figure. To prevent from damage or scratches, insert a piece of cloth between
the outdoor unit and rope, then move the unit.
❋
The appearance of the unit may be different from the picture depending
on the model.
