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 countr y

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.

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:

The unit must not be used by children

or by

unfit persons without suitable supervision.

Do not touch the unit with bare feet

or with

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.

Do not modify safety or regulation devices

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.

Do not open doors or panels

providing access

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.

Handle the unit with the utmost care

(see

weight distribution table) to avoid damage.
