DE-COMMISSIONING DISMANTLING & DISPOSAL

This product contains refrigerant under pressure, rotating parts, and electrical connections which may be a danger and cause injury !

All work must only be carried out by competent persons using suitable protective clothing and safety precautions.

1.

Isolate all sources of electrical supply to the unit including any control system supplies switched by the unit. Ensure that all points of electrical
and gas isolation are secured in the OFF position. The supply cables and gas pipework may then be disconnected and removed. For points of
connection refer to unit installation instructions.

2.

Remove all refrigerant from each system of the unit into a suitable container using a refrigerant reclaim or recovery unit. This refrigerant may
then be re-used, if appropriate, or returned to the manufacturer for disposal. Under NO circumstances should refrigerant be vented to
atmosphere. 
Where appropriate, drain the refrigerant oil from each system into a suitable container and dispose of according to local laws and
regulations governing disposal of oily wastes.

3.

Packaged units can generally be removed in one piece after disconnection as above. Any fixing down bolts should be removed and then the
unit lifted from position using the points provided and equipment of adequate lifting capacity. Reference MUST be made to the unit installation
instructions for unit weight and correct methods of lifting. Note that any residual or spilt refrigerant oil should be mopped up and disposed of as
described above.

4.  After removal from position the unit parts may be disposed of according to local laws and regulations.
