12. Installation
Unpack the unit taking care not to damage its exposed parts. Before discarding it, check the
packaging for any parts or documents, check the packaging for any parts or documents. Check
that the supply voltage is as designated.
POSITIONING OF INDOOR UNIT
1. Check that:
•
There is enough space for easy application, installation and maintenance, both inside and
outside the shelter (see drawings on Chapter 17: maintenance);
•
The roof of the shelter can support the weight of the indoor unit (in case of horizontal
installation);
•
The roof of the shelter is in a horizontal position (check it with a level);
•
The wall of the shelter can support the weight of the indoor unit (in case of vertical installation);
•
The shelter is clean on the inside;
•
The structure is watertight;
•
Indoor ambient is not aggressive (acid, salty, etc.);
•
The inside of the shelter allows a proper air circulation, preventing any re-circulation.
2. According to the kind of roof (or wall), use an appropriate fixing system for the indoor unit. With
concrete or brick walls, use expansion clamps. With other kinds of wall, use through clamps,
sealing them from water (rain) infiltration, or fix the indoor unit to a suitable structure prepared in
advance.
3. The rear side of the indoor unit (where there is the fresh air intake in case of free-cooling) must
be installed with a minimum distance from the wall (floor in case of vertical installation), due to
the position of refrigerant connectors. This minimum distance is 200 mm, for all the models.
Therefore, in case of free-cooling, to connect the fresh air intake of the indoor unit to the opening
on the shelter wall, air ducts are required. These ducts are offered as option (see Chapter 19:
Options), with the following codes:
•
DVIN: duct for vertical indoor unit, rectangular section;
•
DHINREC: extensible, rectangular section duct kit for horizontal indoor unit;
•
DHINRO: flexible round section double duct kit for horizontal indoor unit.
If no-one of these optional ducts is ordered, suitable ducts must be provided.
4. In case of units with free-cooling, two openings are requested on the shelter walls.
•
One is for fresh air intake. This opening must be made according to the dimensions of the
terminal adaptor plates of connection ducts. For the three optional ducts of item 3, opening
dimensions can be found at chapter 19: Options. In all the cases, this opening has to be
protected by rainproof grilles (option GRxxSOP, see Chapter 19: Options).
•
The other opening is for exhaust air discharge. This opening should be placed in a position
which allows a good air circulation during free-cooling. The area of this opening must be at
least: 0.15 m
2
for CST40/50 and 0.24 m
2
for CST60/80/90. An overpressure damper must
be installed on this opening, to avoid internal air going out from it during cooling operation.
This opening must be provided with another
rainproof grille, to avoid rain going into the
shelter (included in option GRxxSOP, see Chapter 19: Options).
5.
Prior to servicing the shelter, disconnect power supply to it. Prior to drilling holes or making
cuts on the shelter, make sure that holes, screws, cables, etc. do not interfere with the equipment
which has already been installed.
