2 - INSTALLATION OF UNIT
2.1 - General
To install an unit EREBA He the following
steps are requested
1. Place the unit
2. Make hydraulic connections to filling the
system with water or brine fluid
3. Make electrical connections
4. Check for water leaks and the water flow
rate control
5. Finally, make commissioning of the unit
2.2 - Moving and placing the unit
2.2.1 - Moving
See §1.2.1 Installation safety considerations.

2.2.2 - Placing the unit
In case of extra-high units the machine
environment must permit easy access for
maintenance operations.
Always refer to § 1.4. Dimensions and
clearances 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.
Only use slings at the designated
lifting points (refer to Figure 2 to
offload the unit).
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.
