 Specic warnings are given in each chapter of the docu-

ment and must be read before starting operations.

 All personnel involved must be aware of the operations

and dangers that may arise when beginning all unit in-

stallation operations.

 Installation performed outside the warnings provided

in this manual and use of the appliance outside the pre-

scribed temperature limits will invalidate the warranty.

 The installation and maintenance of climate control

equipment could be dangerous because there is pres-

surised refrigerant gas and live electrical components

inside the appliances. The installation, initial start-up

and subsequent maintenance phases must be carried

out exclusively by authorised and qualied personnel

(see rst start-up request form enclosed with the ap-

pliance).

 Any contractual or extra-contractual liability for damage

caused to persons, animals or property, due to installa-

tion, adjustment and maintenance errors or improper

use is excluded. All uses not expressly indicated in this

manual are not permitted.

 Only qualied installer companies are authorised to

install the device. After having completed installation,

the installer will issue a declaration of conformity to the

plant manager, as required by the applicable standards

and the guidelines provided by contractor's instruction

manual supplied with the device.

 First start-up and repair or maintenance operations

must be carried out by the Technical Assistance Centre

or by qualied personnel following the provisions of this

manual.

 Do not modify or tamper with the appliance as this can

lead to dangerous situations.

 Use suitable accident-prevention clothing and equip-

ment during installation and/or maintenance opera-

tions. The manufacturer is not liable for the non-ob-

servance of the current safety and accident prevention

regulations.

 In the event of liquid or oil leaks, set the master switch

of the plant to "o" and close the water taps. Call the

authorised Technical Assistance Centre or profession-

ally qualied personnel as soon as possible and do not

work on the appliance yourself.

 In case of replacement of parts, use only original parts.

 The manufacturer reserves the right to make changes

to its models at any time to improve its product, with-

out prejudice to the essential characteristics described

in this manual. The manufacturer is not obliged to add

such modications to machines previously manufac-

tured, already delivered or under construction.

Preliminary warnings for R32

 The appliance must be installed in well-ventilated

rooms with a minimum oor area as indicated in the

Minimum oor area table according to the total refrig-

erant charge in the circuit.

 The refrigerant charge means the total charge of

thecircuitgivenbythesumofthefactorycharge

andanyadditionalcharge.

 Refer to the rating plate on the paired outdoor unit for

the amount of refrigerant gas loaded in the unit.

 If the appliance is located in a poorly ventilated place,

precautions must be taken to prevent stagnation in the

event of leakage of refrigerant to avoid creating a risk

of re or explosion.

 The appliance must be placed in room where there are

no open ames continuously in operation (e.g. a gas

appliance in operation) and no sources of ignition (e.g.

an electric heater in operation).

 Any ventilation openings must be kept free of obstacles.

 Perform the following checks:

• carry out safety checks to ensure that the risk of com-

bustion is minimised

• avoid working in conned spaces

• delimit the area around the workspace

• ensure safe working conditions around the area by

controlling ammable material
