removed from site promptly and all isolation valves on the equipment are closed off.
K) Recovered refrigerant shall not be charged into another refrigerating system unless it has been cleaned and checked.
6.4.16. LABELLING
Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed.
For appliances containing flammable refrigerants, ensure that there are labels on the equipment stating the equipment contains
flammable refrigerant.
6.4.17. RECOVERY
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all
refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the
correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered
refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with
pressure-relief valve and associated shut-off 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 all appropriate refrigerants including, when applicable, 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.

selected and temperature is properly set.
The exhaust hose is detached.
Overflow while moving the unit.
Check if the drain hose is kinked or bent.
Check if the unit is securely positioned.
Check if any loose, vibrating parts.
Noise sounds like water flowing.

SOLUTION
Insert the power cord securely into the wall outlet
Empty the drain pan. See Section 5.10
The range of operating temperature is 5-35
Clear the obstacle.
Clean the air filter. See Section 7
Keep the door and windows closed.
Set the mode and temperature at proper set-point
See Section 5
Make sure the exhaust hose is securely attached.
Empty the water tank before transport.
Straighten the hose to avoid a trap existing.
Place the unit on horizontal and firm ground.
Secure and tighten the parts.
Noise comes from flowing refrigerant. This is normal.
Check the wire harness of the display PCB for damage.
Check connection or replace it. To clean or replace the
temperature sensor.
Check connection or replace it. To clean or replace the
temperature sensor.
Empty the drain pan. See Section 5.10
