2 - INSTALLATION
1.
Inspect shipment. Inspect the unit. If it is damaged, or if
the shipment is incomplete, immediately file a claim with
the shipping company.
2.
Check that the local power supply agrees with the
specification on the unit nameplate.
2.1 - Siting the unit (all sizes)
Check that:
-
The location is able to support unit operating weight (see
Physical Data table).
-
There is sufficient space for servicing around the unit (see
chapter 'Dimensions/clearances).
-
When installing on the ground, the selected site is not
subject to flooding.
-
The installation is in accordance with local rules and
standards which govern the installation of air conditioning
equipment.
-
Vibration absorbers have been provided throughout the
installation to prevent noise from being transmitted.
2.2 - Moving and handling
30SZ/30SZV 004-011
Do not remove the skids until the unit has been moved to its
final location. The units may be moved by means of rollers
under the skids, or with slings.
When lifting with hoist and slings, use spreaders to avoid
damaging the unit panels.
Always place slings under the skids, never attach them to
piping or to any other components on the unit.
2.3 - Location
These units must be located indoors and where the temperature
is maintained between 5°C and 40°C.
The strength of the supporting surface must be adequate to
support the weight of the unit with refrigerant and water charge.
Install reinforcement if necessary.
2.4 - Mounting
Mount the unit on the floor or on a solid platform.
Use an isolation pad under the unit to reduce sound
transmission.
Use flexible joints in the water piping to reduce sound
transmission from the units.
2.5 - Vertical and horizontal installation
These units can be modularly installed, either vertically or
horizontally.
Do not stack more than three units for sizes 004-011 or more
than 2 units for sizes 018-036.
2.5.1 - Modular vertical installation (sizes 004-011)
1.
Place the lower unit in the desired location.
2.
Make 4 holes of 8.5 mm diameter in the top panel of the
lower unit (see Fig. “Holes in the unit top panel”). These
holes are already marked.

3.
On the right- and the left-hand side of the top panel of the
lower unit, position two insulation strips of 15 mm thick-
ness and 10 mm height, so that the holes made previously
are centred under the insulation strip. The insulation strip
absorbs the transmission of vibrations from the higher to
the lower unit. When selecting the insulation strip the unit
weight must be considered. Punch holes into the insulation
strips to align with the holes in the unit top panel (Fig.
“Vertical installation, sizes 004-011”). The insulation
strips and fixings should be determined by the installer.
4.
Place the other unit above the lower unit so that the nuts
that secure the base panel of the upper unit are aligned
with the holes in the panel.
5.
Fix one unit to the other with the four bolts (M8).
6.
The power supply must be separate for each unit. Please
consult the wiring diagrams.
VERY IMPORTANT: Do not stack more than 3 units.
