The Variheat must be kept upright at all times. If lifting with a crane, spreader
bars should be used to protect the top of the cabinet from crushing.
Ensure access to controls, service access panels and connections for users and
service engineers.
Removing the fan module
In order to factory test the Variheat, it will be supplied complete, but if
necessary, the fan module (and fresh air module, where fitted) may be
separated to assist positioning where plantroom access is restricted. The
following actions need to be completed:
Disconnect flexible LPHW hoses
Disconnect fan wiring, taking care to record all wire positions
Unbolt fan module
Unbolt fresh air module, if fitted, if required
Take appropriate care when moving the modules, which are very heavy,
particulary the refrigeration module. Ensure suitable lifting equipment is available
for the movements required.
Ensure all sections remain upright during positioning. To reconnect after
