INSTALLING THE UNIT
SELECTION OF LOCATION
The unit should be installed in a location that meets the following
requirements:
1 The foundation is to be in such way that it causes no vibrations
or noise when the unit is in operation.
2 The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available.
If several units are being installed side by side, the minimum
service space between them must be taken into account.
3 There is no danger of fire due to leakage of inflammable gas.
4 Ensure that water cannot cause any damage to the location by
adding water drains to the foundation and prevent water traps in
the construction.
5 Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb
anyone.
6 Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction. Frontal wind will
disturb the operation of the unit. If necessary, use a windscreen
to block the wind.
7 In heavy snowfall areas, select an installation site where snow
will not affect operation of the unit.
The equipment is not intended for use in a potentially explosive
atmosphere.
DESCRIPTION DIMENSIONS
For dimensions of the unit, refer to the outlook diagram delivered with
the unit.
INSPECTING AND HANDLING THE UNIT
The units are packed in a wooden crate and attached on a wooden
pallet.
At delivery, the unit should be checked and any damage should be
reported immediately to the carrier claims agent.
When handling the unit, take into account the following:
1 Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
2 Lift the unit preferably with a crane and 2 belts in accordance
with the instruction sticker on the unit.
3 When lifting the unit with a crane, always use protectors to
prevent belt damage and pay attention to the position of the
unit’s centre of gravity.
4 Bring the unit as close to its final installation position in its
original package to prevent damage during transport.
