4.3 UNPACKING

The packaging must be carefully removed to avoid the risk of damaging the unit. The packaging includes

various materials: wood, cardboard, nylon, etc.

It is recommended to keep them separately and deliver them to suitable waste disposal or recycling

facilities in order to minimise their environmental impact.

Attention

: if the unit is supplied with a pump or pumps and/or tank, you will find the expansion tank

packaged in the fan compartment; it must be fixed to the pump intake pipe, where a “TEE” is fixed so as

to form a tight seal, or on the tank itself. Remove the cap and screw in the expansion tank (this should be

done by qualified personnel), check the pre-fill pressure (0.5 - 1.0 bars-r) before filling the water circuit

and starting up the chiller.

Attention

: the size of the expansion tank will depend both on the volume of water contained in the

system and the water temperature range; always check the tank capacity in relation to the water content

of the system.

4.4 SITING

You should bear in mind the following aspects when choosing the best site for installing the unit and the

relative connections:

- size and origin of water pipes;

- location of power supply;

- accessibility for maintenance or repairs;

- solidity of the supporting surface;

- ventilation of the air-cooled condenser and necessary clearance;

- direction of prevalent winds: avoid positioning the unit in such a way that the prevalent winds favour the

backflow of air to the condenser coils; a speed of 8 m/s (28.8 km/h) already generates a sufficient

stagnation pressure to guarantee approx. 60% of the nominal air flow rate.[In situations where the

action of air currents is inevitable and there is a simultaneous presence of temperatures below – 5°C,

the control of condensation for low outdoor temperatures must be of the flooding type or with a device

for choking the condensing exchanger -contact the technical department for further details]

- possible reverberation of sound waves.

All models belonging to the LCE series are designed and built for outdoor installation: avoid covering

them with roof structures or positioning them near plants (even if they only partly cover the unit) which

may interfere with the regular ventilation of the unit condenser.

It is a good idea to create a base of adequate dimensions to support the unit. This precaution becomes

essential when the unit is to be sited on unstable ground (various types of soil, gardens, etc.).

We recommend placing a rigid rubber strip between the base frame and the supporting surface.

Whenever more effective insulation is required, it is recommended to use vibration-damping rubber or

spring supports (ref. par. 15).

In the case of installation on roofs or intermediate storeys, the unit and pipes must be insulated from

walls and ceilings by placing rigid rubber joints in between and using supports that are not rigidly

anchored to the walls.

If the unit is to be installed in proximity to private offices, bedrooms or areas where noise levels must be

kept down, it is advisable to conduct a thorough analysis of the sound field generated and verify its

compatibility with the local laws in force.
