Monobloc Outdoor Unit Installation Manual
7.1.2 Positioning the Unit:
In case of extra-high units the machine environment must permit easy access for maintenance operations.
Always refer to the Dimensions and Clearances figure to confirm that there is adequate space for all connections
and service operations. For the centre of gravity coordinates, the position of the unit mounting holes, and the weight
distribution points, refer to the certified dimensional drawing supplied with the unit.
Typical applications of these units do not require earthquake resistance. Earthquake resistance has not been
verified.
Before siting the unit check that:
•
The permitted loading at the site is adequate or that appropriate strengthening measures have been taken.
•
If the unit has to operate as a heat pump in temperatures below 0°C it must be raised at least 300 mm from the
ground. This is necessary to avoid ice build-up on the unit chassis and also to permit correct unit operation in
locations where the snow level may reach this height.
•
The unit is installed level on an even surface (maximum tolerance is 5 mm in both axes).
•
There is adequate space above the unit for air flow and to ensure access to the components (see dimensional
drawings).
• The number of support points is adequate and that they are in the right places.
• The location is not subject to flooding.
• For outdoor installations, where heavy snowfall is likely and long periods of sub-zero temperatures are normal,
provision has to be made to prevent snow accumulating by raising the unit above the height of drifts normally
experienced. Baffles may be necessary to deflect strong winds. They must not restrict air flow into the unit.
