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 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.
