 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.
