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.
