Positioning
The Variheat must be kept upright at all times. The cabinet is designed to be
supported from the bottom. If lifting with a crane, spreader bars should be used
to protect the top of the cabinet from crushing.
Siting
Ensure sufficient access to controls, service access panels and connections for
users and service engineers. Due consideration should be given to Health and
Safety when designing access 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:
y
Disconnect flexible LPHW hoses
y
Disconnect fan wiring, taking care to record all wire positions
y
Unbolt fan module
y
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
