GENERAL WARNINGS
These units have been designed to chill
and/or heat water and must be used in applica-
tions compatible with their performance char-
acteristics.
Incorrect installation, regulation and mainte-
nance or improper use absolve the manufac-
turer from all liability, whether contractual or
otherwise, for damage to people, animals or
things. Only those applications specifically indi-
cated in this list are permitted.
Read this manual carefully. All work must
be carried out by qualified personnel in confor-
mity with current legislation in the country
concerned.
The HRAT-HRAN units contain R22 refrigerant
gas which damages the ozone layer. At the end
of their working life, they should be taken to a
special collection centre, as per the legislation
in force. Care should be taken to avoid damage
to the gas circuit and coil.
The guarantee is invalidated if the above
instructions are not respected and if the unit is
started up for the first time without the pres-
ence of personnel authorised by the Company
(where specified in the supply contract) who
should draw up a “start-up” report.
The documentation supplied with the
unit must be consigned to the owner who
should keep it carefully for future consultation.
When the items are consigned by the
carrier, check that the packaging and the unit
are undamaged. If damage or missing compo-
nents are noted, indicate this on the delivery
note. A formal complaint should be sent via fax
or registered post to the After Sales Depart-
ment within eight days from the date of receipt
of the items.
When operating equipment involving the use of electricity
and water, a number of fundamental safety rules must be
observed, namely:

wet or damp parts of the body.
Do not carry out cleaning operations without
disconnecting the unit from the electricity supply by
placing the general installation switch in the “off”
position.

without authorisation and instructions from the
manufacturer.
Do not pull, detach or twist the electrical
cables coming from the unit, even when discon-
nected from the mains electricity supply.

to the internal parts of the unit without first ensur-
ing that the general installation switch is in the off
position.
Do not introduce pointed objects through the
air intake and outlet grills.
Do not dispose of, abandon or leave within
reach of children packaging materials (cardboard, sta-
ples, plastic bags, etc) as they may represent a hazard.
Respect safety distances between the unit and
other equipment or structures. Guarantee adequate
space for access to the unit for maintenance and/or
service operations.
Power supply: the cross section of the electrical
cables must be adequate for the power of the unit
and the power supply voltage must correspond with
the value indicated on the respective units.All units
must be earthed in conformity with current legisla-
tion in the country concerned.
Hydraulic connections should be carried out as
indicated in the instructions to guarantee correct
operation of the unit. Empty the hydraulic circuit or
add glycol if the unit is not used during the winter.
