ELECTION
OF
LOCATION
The EUWAC unit should be installed in a location that meets the
following requirements:
1
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
2
The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available. (See
figure 2 and figure 3.)
If several units are being installed side by side in parallel, 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
Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb
anyone.
5
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.
6
Ensure that water cannot cause any damage to the location in
case it drips out of the unit (e.g. in case of a blocked drain pipe).
7
A drain is provided and there is
enough space to install a trap
with a minimum fall of 75 mm
between the drain outlets of the
unit and the drain.
The equipment is not intended for use in a potentially explosive
atmosphere.

NSPECTING
AND
HANDLING
THE
UNIT
The EUWAC units are packed in a cardboard box and attached on a
wooden pallet.
At delivery, the package 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.
Follow the instructions marked by the symbols on the package:
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
Do not use straps to move the unit.
2.
Lift the unit preferably with a fork-lift, a manual pallet mover or a
crane and belts.
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.
U
NPACKING
AND
PLACING
THE
UNIT
1
Cut the straps and remove the cardboard box from the unit.
2
Remove the four screws fixing the unit to the pallet.
3
Lift the unit from the pallet and place it on its installation position.
4
Connect the air inlet (lower part of the unit) to the air inlet
ducting and the air outlet (upper part of the unit) to the air outlet
ducting. Always provide a flexible connection between the
ducting flanges of the unit and the ducts to prevent vibrations
and noise generation.
