Symbols with the following meanings are used in some parts of the manual:

CAUTION = For actions requiring special care and adequate training.

FORBIDDEN = For actions which SHOULD NEVER be done.

IDENTIFICATION

The unit can be identified through:

- - Rating plate It bears the technical and performance data of the equipment.

Should this plate be damaged or mislaid, ask your local Technical Support Service for a duplicate.

Tampering with the rating plate, removing it or whatever else does not allow a sure identification of the product hinder any installation or maintenance interventions.

GENERAL DIRECTIONS

After unpacking the appliance, check it for integrity and completeness. Should the content not match your order, please contact the retailer who sold the equipment.

The equipment must be installed by a qualified company which, at the end of the work, must provide the proprietor with a declaration of conformity stating that the installation complies with the best practice and the applicable national and local regulations, as well as the indications of this instruction manual.

These appliances were made for room air heating and/or conditioning and must be destined for this use consistently with their performance characteristics. The manufacturer does not assume any contractual or extra-contractual liability for damages caused to people, animals or things by installation, adjustment and maintenance errors or improper use.

In case of water leakage, turn OFF the main system circuit breaker and close the water taps. Immediately call the Technical Support Service or professionally qualified personnel and do not personally intervene on the equipment.

The appliance contains refrigerant gas R 410A; act carefully in order not to damage the gas circuit and the finned coil. In case of refrigerant leakage, turn OFF the main system circuit breaker. Immediately call the Technical Support Service or professionally qualified personnel and do not personally intervene on the equipment.

The appliances must be exclusively equipped with original accessories. The manufacturer is not responsible for any damages resulting from the improper use of the appliance and the use of non-original accessories and materials.

The references to laws, regulations, directives and technical standards mentioned in this manual have a mere informational purpose and are valid at the printing date of the same. The manufacturer cannot be bound towards third parties on account of new regulations or amendments to those already in force.

The installations to be made (gas piping, electric power supply, etc.) must be adequately fixed and avoid the risk of stumbling. The manufacturer is responsible for the conformity of his product to the laws, directives and standards which were in force at the time of

marketing. The knowledge and observance of regulations and standards about the system designing, installation, operation and maintenance are at the exclusive charge of the designer, installer and user according to their spheres of competence.

The manufacture is not held responsible for the non-observance of the instructions contained in this manual, for the consequences of an y unexpected operation or for any translations from which wrong interpretations may arise.

This appliance must be installed in accordance with the applicable national and local regulations and must be only used in a sufficiently ventilated environment. Carefully read the instructions before installing and operating this equipment.

Should the unit be connected in parallel to a boiler, close the chiller cocks during the boiler operation. The temperature of the circulating water inside the chiller should never exceed 60°C.

If you are not going to use the equipment for a long time, please do the following: – Turn OFF the main system circuit breaker – Close the water taps – If there is danger of freezing, make sure an antifreeze liquid has been added to the system, otherwise empty the system

This instruction manual is an integral part of the appliance, therefore it must be kept with care and ALWAYS accompany the appliance if it is transferred to another proprietor or user or moved to another system.. Should this manual be damaged or mislaid, ask your local Technical Support Service for a new copy.

The repair or maintenance work must be carried out by the Technical Support Service or qualified personnel according to the prescriptions of this manual. Do not alter or tamper with the appliance as this may lead to dangerous situations, and the manufacturer of the ap pliance will not be held responsible for any damages caused.

Under adverse visibility conditions, use lighting devices enabling a perfect vision of all parts and components. The refrigerant fluid contained in the refrigerating circuit is R-410A and it is not classified as dangerous in accordance with directive

1999/45/EC and relevant amendments. Avoid high steam concentrations which may cause headache, vertigo, somnolence, nausea and other troubles.

In case of skin contact with the liquid, there is a residual risk of freezing through fast evaporation. Seek medical advice. In case of inhalation, breath fresh air. Administer oxygen if breathing is difficult. Seek medical advice. In case of eye contact, immediately flush with running water for at least 15 minutes. Seek medical advice.

The refrigerant fluid must be disposed of through authorized waste-disposal companies. In any case, the fluid must be recovered in proper storage tanks.

FUNDAMENTAL SAFETY RULES

We remind you that the use of products using electric power, gas or gas oil entails the observance of some fundamental safety rules, like the following:

The use of the appliance by children and unattended disabled people is prohibited. Do not touch the appliance while barefoot and with wet or humid body parts Do not perform any cleaning or maintenance before disconnecting the appliance from the mains (by turning OFF the main system circuit

breaker). The safety and setting devices should not be altered without the appliance manufacturer’s consent and indications Do not pull, tear or twist the electrical cables on the appliance, although this is disconnected from the mains. Do not insert sharp objects through the air intake and supply grilles. Do not open the equipment’s internal part access doors without first turning off the main system circuit breaker. Do not abandon or leave to the children’s reach the packing material (cardboard, iron bands, plastic bags, etc.) as this is a potential source

of danger. Do not install the appliance in environments with an aggressive atmosphere Do not place any objects onto the equipment, nor slide them through the grille. Do not use any adapters, multiple-outlet sockets or extensions for the electrical connection of the appliance. Do not distribute this product in different countries, since it must be modified as to technical documentation and layout. Do not perform any maintenance before disconnecting the appliance from the mains (by turning OFF the main all-pole system circuit

breaker).

EQUIPMENT DESCRIPTION

The units are divided into two families:

– HEAT PUMPS, BESST series: some available with single-

phase power supply, others with three-phase power supply, capable of producing both hot water for heating and cold water for cooling household, residential and industrial environments.

– HEAT PUMPS, BESST/R series: also av ailable with three-

and single-phase power supply, capable of producing both hot water for heating and cold water for cooling household, residential and industrial environments and provided with supplementary electrical resistor for correct operation even under very critical weather conditions.

They are used in combination with terminal or fan-coil units in small and medium-large systems. They are designed for outdoor installation and the used materials have been selected to meet this special requirement.

They use a scroll-type rotating compressor, mounted on antivibration supports inside an adequate compartment, and electronically-controlled variable-speed helical fans, which ensure particularly noiseless operation. For three-phase versions, a phase monitor is standard supplied to check the proper compressor rotation. The AISI 318 stainless steel plate heat exchanger, on utility end, is insulated with an anti-condensation coating and complete with a flow controller. The units are equipped with various safety devices, such as pressure-switches, hydrometer, sensors, specific automatic switches and phase monitor (only for three-phase units). An electronic, microprocessor-controlled equipment supervises the operation. They are also provided with an inertial storage tank which is integrated into the unit as a standard.
