SECTION 9 - DECOMMISSIONING, DISMANTLING, AND DISPOSAL
Never release refrigerant to the atmo-
sphere when emptying the refrigerating
circuits. Suitable retrieval equipment
must be used. If reclaimed refrigerant
cannot be reused, it must be returned to
the manufacturer.
Never discard used compressor oil, as it
contains refrigerant in solution. Return
used oil to the oil manufacturer.
Unless otherwise indicated, the operations described
below can be performed by any properly trained main-
tenance technician.
1. Isolate all sources of electrical supply to the unit,
including any control system supplies switched
by the unit. Make sure that all points of isolation
are secured in the off position.
2. Disconnect and remove the supply cables. For
connection points, refer to
DLING, STORAGE, INSTALLATION AND RE-
3. Remove all refrigerant from the system into a suit-
able container, using a refrigerant reclaim or re-
covery unit. This refrigerant may then be reused,
if appropriate, or returned to the manufacturer for
disposal. Under NO circumstances should refrig-
erant be vented to the atmosphere.
4. Drain the refrigerant oil from the system into a
suitable container and dispose of according to lo-
cal laws and regulations. Any spilled oil should be
mopped up and similarly disposed of.
5. Isolate the unit heat exchanger from the external
water systems and drain the heat exchanger sec-
tion of the system. If no isolation valves are in-
stalled it may be necessary to drain the complete
system.
6. If glycol was used in the water system, or chemi-
cal additives are contained, dispose of the solu-
tion in a suitable and safe manner. Under NO cir-
cumstances should any system containing glycol
be drained directly into domestic waste or natural
water systems.
7. After draining, disconnect and remove the water-
lines.
8. Remove the packaged units in one piece after dis-
connecting the unit. Remove fixing down bolts,
and then lift the unit from position, using the
points provided and equipment with adequate lift-
ing capacity.
Refer to
SECTION 3 - HANDLING, STORAGE, IN-
for unit installation
for
unit weights.
Units which cannot be removed in one piece after dis-
connection must be dismantled in position. Handle
each component carefully. Where possible, dismantle
units in the reverse order of installation.
Make sure that while components are being removed,
the remaining parts are supported in a safe manner.
Only use lifting equipment of adequate
capacity.
After removing the unit from position, dispose the
unit parts according to local laws and regulations.
The following factors can be used to convert from
English to the most common metric values.
