SAFETY INSTRUCTIONS

•

READ THE INSTRUCTION MANUAL CAREFULLY BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT.

• The condenser is factory precharged with dry nitrogen to prevent the ingress of any water vapour. Before removing the plugs from
the inlet and outlet connections for installation, discharge the nitrogen by means of the needle valve on the inlet manifold

• Work on the condenser should only be carried out by authorised and suitably qualified personnel

• The condenser contains live electrical parts and rotating devices: before carrying out any work on the electrics or on the fan, isolate

the unit (turn optional isolator to position ‘O’)

• The condenser contains gas above atmospheric pressure: tampering with connections or pipework can cause leakage of
compressed gas

• The temperature of the inlet pipe to the condenser can rise above 70°C and therefore presents the risk of burns

• INSTALL THE CONDENSER IN A POSITION WHICH IS INACCESSIBLE TO UNAUTHORISED PERSONNEL: the fins of the heat

exchanger are made from thin aluminium sheet and can cause cuts in the event of accidental contact.

NAMEPLATE

The nameplate of the condenser is located on one side (see
Fig. 1) and contains the following data:

• Unit model;

• Serial number;

• Year of manufacture;

• Current and power absorbed;

• Standard settings.

TRANSPORT - POSITIONING ON SITE

The condenser leaves the factory in perfect condition;
At the moment of delivery its condition should be carefully
checked and any damage which might have been caused in
transit should be notified in writing to the haulier.
During transit and positioning on site:

• Do not overturn or lean the condenser on its side.

• Before removing the packaging carry the condenser to the

nearest possible point to the actual installation location by
using a pallet truck or a forklift securing the unit to ensure
that it does not fall off.

• Carefully cut or remove the strapping and then remove the
packaging.

DIMENSIONS AND WEIGHT

See drawing DIUI ........... attached.

INSTALLATION

Position the condenser in the open air out of direct sunlight.
It can be installed:

• with horizontal air discharge (standard version) for best
protection (from snow or from objects falling from above)
and easier maintenance; in this configuration the
condenser must be protected from the wind which could
interfere with the operation of the fan;

• with vertical air discharge ; the optional leg kit is available
for this configuration (four legs up to model CAL 0661; six
legs for the larger models) and it is recommended for
installation in windy locations or wherever a horizontal air
flow would be obstructed. Assembly instructions are
included with the leg kit.

The limited weight of the CAL condensers means that they can
be installed on relatively lightweight bases.
Position the condenser on a solid, level surface.
Fix the condenser down using the appropriate bolt holes in the
base (horizontal air discharge) or in the

bottoms of the legs

(vertical air discharge): See drawing No. DIUI........ attached for

dimensions.
Ensure that the necessary clearances for free circulation of the
air are left around the unit as shown in Fig.2.

Fig. 2a Horizontal Air Flow

Fig. 2b Vertical Air Flow

Use shims if necessary to ensure a level installation to within
one degree.

INSTALL THE CONDENSER IN A POSITION WHICH
IS INACCESSIBLE TO UNAUTHORISED

PERSONNEL:
The heat exchanger fins are made from aluminium sheet
which is only 0.1 mm thick and could cause cuts in the
event of forceful accidental contact.

N.B. the fan characteristic does not allow any ducting of the air flow.
