INSTALLATION

 RECEIPT AND HANDLING

The machine is sent from the factory wrapped with

estincoil placed on a loading pallet.

Before handling the unit, verify the lifting capacity of

the machines used.

Handling must be performed by qualified, suitably

equipped staff.



- Whenever it is envisioned to lift the machine

with belts, so as not to damage the structure,

place protections between the belts and the

framework. It is prohibited to stop below the unit

during lifting.

 SELECTION AND PLACE OF INSTALLATION

The WRL water/water INDOOR heat pump with

gas side inversion (R410A) is sent from the factory

already inspected and only requires electric and

hydraulic connections in the place of installation.

Before beginning installation consent with client and

pay attention to the following recommendations:

•The support surface must be capable of

supporng the unit weight.

•The safety distances between the units

and other appliances or structures must be

scrupulously respected.

•The unit must be installed by a skilled tech-

nician in compliance with the naonal law

in force in the country of desnaon.

•It is mandatory to foresee to the necessary

technical space in order to allow ROUTINE

AND EXTRAORDINARY MAINTENANCE in-

tervenons.

• Remember that whilst operaonal the chill-

er can cause vibraons; therefore “VT”an-

vibraon mounts (accessories) are recom-

mended, xed on the base according to the

assembly layout.

• Fix the unit, checking that it is level.
