Installation and operation manual
6
Point of attention regarding quality of the public electric power
supply.
This equipment complies with respectively:
■ EN/IEC 61000-3-11
(1)
provided that the system impedance Z
sys
is less then or equal to Z
max
.
■ EN/IEC 61000-3-12
(2)
provided that the short-circuit power S
sc
is greater than or equal to the minimum S
sc
value
at the interface point between the user's supply and the public
system. It is the responsibility of the installer or user of the equipment
to ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with
respectively:
■ Z
sys
less than or equal to Z
max
■ S
sc
greater than or equal to the minimum S
sc
value.
For cable selection refer to "4.6.5. Connection of the unit power
supply and communication cable(s)" on page 13.
For the recommended fuses refer to the technical data book.
4. INSTALL THE CHILLER
4.1. Unpack the unit
4.1.1. Inspection
At delivery, the unit must be checked and any damage must be
reported immediately to the carrier’s claims agent.
4.1.2. Handling
When handling the unit, take into account the following:
2 Choose on beforehand the path along which the unit is to be
brought in.
3 Bring the unit as close as possible to its final installation position
in its original package to prevent damage during transport.
Refer to figure 4.
1 Packaging material
2 Belt sling
3 Protector
4 Opening
5 Forklift
4 Lift the unit preferably with a crane and 2 belts of at least 8 m
long as shown in the figure above.
Always use protectors to prevent belt damage and pay attention
to the position of the unit's centre of gravity.
A forklift can only be used for transport as long as the unit
remains on its pallet as shown above.
4.1.3. Unpacking
■ Remove the packing material from the unit:
-Take care not to damage the unit when removing the shrink
foil with a cutter.
- Remove the top palette(s) and cardboard plate(s) before
removing the upright cardboard protection pieces.
Refer to figure 3.
■ Remove the screws fixing the unit to its pallet.
4.2. Install the unit
4.2.1. Place the unit on its final place
1 Lift the unit onto its proper foundation. Refer to figure 5.
1 Belt sling
2 Protector
3 Opening
2 Lift the unit preferably with a crane and 2 belts of at least 8 m
long as shown in the figure above.
Always use protectors to prevent belt damage and pay attention
to the position of the unit's centre of gravity.
■ Make sure the unit is installed level on a sufficiently strong base
to prevent vibration and noise.
■ The height of the foundation must at least be 150 mm from the
floor.
In heavy snowfall areas, this height should be increased
dependant on the installation place and condition.
(1) European/International Technical Standard setting the limits for voltage
changes, voltage fluctuations and flicker in public low-voltage supply
systems for equipment with rated current ≤75 A.
(2) European/International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage systems
with input current >16 A and ≤75 A per phase.

that children will not play with them. Children playing
with plastic bags face danger of death by suffocation.
CAUTION
Use a belt sling that adequately bears the weight of
the unit.
NOTICE
A forklift can not be used!
NOTICE
