DECLARATION OF CONFORMITY

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.

Read the Manual

Risk of electric shock

Unit is remotely

controlled and may

start without warning

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  reused,  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 unit can generally be removed in one piece after disconnection as above. Any fixing down bolts should

be removed and then 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.
