DECOMMISSIONING, DISMANTLING AND DISPOSAL
Never release refrigerant to the atmosphere
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.
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
maintenance technician.
General
Isolate all sources of electrical supply to the unit
including any control system supplies switched by
the unit. Ensure that all points of isolation are secured
in the ‘OFF’ position. The supply cables may then be
disconnected and removed. .
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. Drain the refrigerant oil from each system
into a suitable container and dispose of according to
local laws and regulations governing the disposal of oily
wastes. Any spilt oil should be mopped up and similarly
disposed of.
Isolate the unit heat exchanger from the external water
systems and drain the heat exchanger section of the
system. If no isolation valves are installed it may be
necessary to drain the complete system.
If glycol or similar solutions have been used
in the water system, or chemical additives
are contained, the solution MUST be
disposed of in a suitable and safe manner.
Under NO circumstances should any
system containing glycol or similar
solutions be drained directly into domestic
waste or natural water systems.
After draining, the water pipework can be disconnected
and removed.
Packaged units can generally be removed in one piece
after disconnection. Any fixing down bolts should be
removed, the unit should be lifted from position using
the points provided and equipment of adequate lifting
capacity.
Reference should be made to
INSTALLATION
for unit
installation instructions,
TECHNICAL DATA
for unit
weights and
HANDLING AND STORAGE
for handling.
Units which cannot be removed in one piece after
disconnection, must be dismantled in position. Special
care should be taken regarding the weight and handling
of each component. Where possible units should be
dismantled in the reverse order of installation.
Residual refrigerant oil and glycol or similar
solutions may remain in some parts of the
system. These should be mopped up and
disposed of as described above.
It is important to ensure that whilst components are
being removed the remaining parts are supported in a
safe manner.
Only use lifting equipment of adequate
capacity.
After removal from position the unit parts may be
disposed of according to local laws and regulations.
