IDENTIFICATION

U I A

The chiller can be identified by the:

Packaging label

Giving the data identifying the product.

Rating plate

Giving the technical and performance data of the unit.
If this is lost, ask the After Sales Service for a replacement.

Tampering with or the removal or absence of rating

plates or other means enabling the unit to be identified
causes problems during installation and maintenance.

RECEIVING, HANDLING AND INSTALLING THE PRODUCT 

I A

The chillers are supplied accompanied by:
- installation, user and maintenance manual;
- CE declaration;

CHOICE OF INSTALLATION SITE

Before installing the unit, agree with the customer the site
where it will be installed, taking the following points into con-
sideration:
• Check that the fixing points are adequate to support the

weight of the unit;

• Pay scrupulous respect to safety distances between the

unit and other equipment or structures to ensure that air
entering the unit and discharged by the fans is free to cir-
culate.

HANDLING AND POSITIONING

The unit should always be handled by qualified personnel
using equipment adequate for the weight of the chiller.
• Before handling the unit, check the capacity of the lift

equipment used, respecting the instructions on the pack-
aging.

• To move the unit horizontally, make appropriate use of a

lift truck or similar, bearing in mind the weight distribution
of the unit. 
To lift the unit, insert tubes long enough to allow position-
ing of the lifting slings and safety pins in the special feet
on the unit.
For the sizes of these tubes, see the figures shown in the
corresponding section.

• To avoid the slings damaging the unit, place protection

between the slings and the unit. 
Position the unit in the site indicated by the customer.
Place either a layer of rubber (min. thickness 10 mm) or
vibration damper feet (optional) between the base and
support surface. 
Fix the unit, making sure it is level and that there is easy
access to water and electrical components. 
If the site is exposed to strong winds, fix the unit ade-
quately using tie rods if necessary. 
If a heat pump unit is being installed, make sure the con-
densate is drained using the drain hose supplied as stan-
dard. 

Prevent leaves, branches or snow from accumulating
around the unit. These could reduce the efficiency of the
unit.

The installation, user and maintenance manual

is an

integral part of the unit and should therefore be read and
kept carefully. 

It is recommended

that the packaging should not be

removed until the unit is located in the installation site.

During transport, the chiller 

should be kept in a verti-

cal position

The weight of the chiller 

is biased towards the com-

pressor side (side of the packaging with the barcode,
see the figure at the foot of the page).

Do not

dispose of packaging materials in the environ-

ment or leave them within reach of children as they may
represent a hazard.
