GENERAL WARNINGS
These units have been designed to chill and/or heat water and must be used in applications compatible with their performance characteristics. Incorrect installation, regulation and maintenance or improper use absolve the manufacturer from all liability, whether contractual or otherwise, for damage to people, animals or things. Only those applications specifically indicated in this list are permitted. Read this manual carefully. All work must be carried out by qualified personnel in conformity 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.
FUNDAMENTAL SAFETY RULES

INSTALLATION
To move the unit in the horizontal, make appropriate use of a lift truck or similar, bearing in mind the weight distribution of the unit. To lift the unit, insert tubes long enough to allow positioning of the lifting slings and safety pins into the special holes in the bed plate of the unit. To avoid the slings damaging the unit, place protection between the slings and the unit. Position the unit in the site indicated by the customer. Place either a layer of rubber (min. thickness 10 mm) or vibration damper feet (optional) between the bed plate and support surface. Fix the unit, making sure it is level and that there is easy access to hydraulic and electrical components. If the site is exposed to strong winds, fix the unit adequately to the support surface using tie rods if necessary. If a heat pump unit is being installed, fit a condensate collection pan (available as accessory).
CHOICE OF INSTALLATION SITE Before installing the unit, agree with the customer the site where it will be installed, taking the following points into consideration: - check that the fixing points are adequate to support the weight of the unit; - pay scrupulous respect to safety distances between the unit and other equipment or structures to ensure that air entering the unit and discharged by the fans is free to circulate. - The unit must be installed in a space designed to house technical installations dimensioned according to current legislation in the country concerned and large enough to allow access for maintenance. If this is not possible, then use of the protection grill kit is indispensable (HRAT-HRAN only). POSITIONING Before handling the unit, check the capacity of the lift equipment used, respecting the instructions on the packaging.

HYDRAULIC CONNECTIONS
3. Two gate valves (normal in inlet and calibrating in outlet); 4. A flow switch (in inlet) or a differential pressure switch (inlet-outlet); 5. Two thermometers (inlet and outlet); 6. An inlet filter as close as possible to the evaporator and positioned to allow easy access for routine maintenance. The flow of water to the refrigerating assembly must conform to the values given on page 17-18. The flow of water must be maintained constant during operation. The water content of the unit must be such as to avoid disturbing operation of the refrigerant circuits. See the values given on page 26.
The choice and installation of components is the responsibility of the installer who should follow good working practice and current legislation. Before connecting the pipes, make sure they do not contain stones, sand, rust, dross or other foreign bodies which might damage the unit. Construction of a by-pass is recommended to enable the pipes to be washed through without having to disconnect the unit (see drain valves).The connection piping should be supported in such a way as to avoid it weighing on the unit. It is recommended that the following devices are installed in the hydraulic circuit of the evaporator. 1. Two pressure gauges with a suitable scale (inlet and outlet); 2. Two vibration damper joints (inlet and outlet); UNIT

Voltage must be within a tolerance of ±10% of the rated power supply voltage for the unit (for three phase units, the unbalance between the phases must not exceed 3%). If these parameters are not respected, contact the electricity supply company. For electrical connections, use double insulation cable in conformity with current legislation in the country concerned. Install, if possible near the unit, an appropriate protection device to isolate the unit from the mains supply with delayed characteristic curve, contacts opening by at least 3 mm and an adequate interruption and differential protection capacity. If this device is not visible from the electrical panel of the unit, it should be lockable An efficient earth connection is obligatory. Failure to earth the appliance absolves the manufacturer of all liability for damage. In the case of three phase units, ensure the phases are connected correctly.
The chillers leave the factory completely cabled and ready for connection to the mains electricity supply and for the flow switch, remote ON/OFF switch and pump to be connected to the terminals provided. Electrical connections must be carried out by qualified personnel in respect of current legislation. For all electrical work, refer to the electrical wiring diagrams in this manual. You are also recommended to check that: - The characteristics of the mains electricity supply are adequate for the power ratings indicated in the electrical characteristics table below, also bearing in mind the possible use of other equipment at the same time. Power to the unit must be turned on only after installation work (hydraulic and electrical) has been completed. All electrical connections must be carried out by qualified personnel in accordance with current legislation in the country concerned. Respect instructions for connecting phase, neutral and earth conductors. The power line should be fitted upstream with a suitable device to protect against short-circuits and leakage to earth, isolating the installation from other equipment.
Do not use water pipes to earth the unit.

ELECTRICAL POWER CONNECTIONS For the functional connection of the unit, bring the power supply cable to the electrical panel inside the unit and connect it to terminals U-N and PE, respecting the (U) phase, (N) neutral and (PE) earth in the case of single phase units (230V~50Hz), and U-V-W phases, N neutral and PE earth in three phase units (400V-3N~50Hz). AUXILIARY CONNECTIONS All terminals referred to in the explanations below are to be found on the terminal board inside the electrical panel and described as “installer terminals”. REMOTE START UP AND SHUT DOWN To fit a remote on/off device, the jumper must be replaced with a switch connected to terminals 6 and 7 of the installer terminal board. For timed operation, connect a daily or weekly timer between terminals 6 and 7. REMOTE HEATING/COOLING CONTROL To fit a remote heating/cooling switching device, the jumper must be replaced with a switch connected to terminals 8 and 9 of the installer terminal board.To install the kit, proceed as follows: - Select the parameter H27 on the HSW4 control panel and set the value to 2. REMOTE ALARM For remote display of unit shut-down due to malfunction, an audible or visual alarm warning device can be connected between terminals 10 and 11. Connect the phase to terminal 11 and the alarm warning device between terminal 10 and neutral (max. load: 500mA at 24V).
REMOTE KEYBOARD KIT The remote keyboard kit can be used to display all unit functions and access the parameters of the electronic board from a point located at some distance from the unit itself. It consists of a remote control module and a transformer. To install the kit, proceed as follows: - disconnect the power supply by means of the QS1 door lock disconnecting switch then access the inside of the electrical panel. - connect the remote control module with 3 wires to terminals 18, 19 and 20 on the installer terminal board. terminal 18 connected to terminal 26 on the module; terminal 19 connected to terminal 24 on the module; terminal 20 connected to terminal 25 on the module; Make sure that parameter H27 is set to 0. To avoid interference due to magnetic fields, the use of shielded cable is recommended. The cable should not be more than 100m long. CONNECTING A PUMP If a pump is to be fitted to the unit or storage tank, it should be connected to terminals 16, 17 and earth on the installer terminal board. CONNECTING A FLOW SWITCH If a flow switch is used, connect it to terminals 14 and 15 on the installer terminal board after removing the jumper.
It is prohibited to earth the secondary of the 24V transformer, as the chiller is compliant to the standards in force in the country concerned.

OPERATING CHARACTERISTICS
Set point in cooling (factory set) = 12°C, hysteresis = +3°C. The compressor starts with water temperatures above 12°C+3°C (15°C) The compressor shuts down with water temperatures of less than 12°C. In the event of temporary power failure, when the power returns, the mode set previously will be retained in the memory.
COMPRESSOR START UP DELAY There are two functions to prevent the compressor starting up too frequently: - Minimum time since last shut-down 180 seconds. - Minimum time since last start-up 300 seconds.
PUMP The electronic board provides an output for the management of the circulating pump. The pump starts when the assembly is powered and at least 60 seconds before the compressor starts, and stops 60 seconds after the assembly shuts down. After the first 60 seconds of pump operation when the water flow is at full speed, the water flow alarm functions are activated (differential pressure switch and flow switch).
FROST PREVENTION ALARM To prevent the water freezing and damaging the plate heat exchanger, the microprocessor shuts down the compressor if the temperature measured by the heat exchanger outlet temperature sensor is less than +3C. The frost prevention temperature set point can be modified by an authorised service centre only and only after verifying that the hydraulic circuit contains antifreeze. The tripping of this alarm shuts down the compressor but not the pump, which remains active. To reset normal functions, the outlet water temperature must rise to more than +7°C. Reset is manual.
WATER FLOW ALARM The microprocessor provides for the management of a water flow alarm controlled by a differential pressure switch fitted as standard on the appliance and a flow switch to be installed on the water delivery piping. This safety device may trip after the first 60 seconds of pump operation when the water flow is up to speed. The tripping of this alarm shuts down the compressor but not the pump, which remains active. To reset normal functions, the alarm contact must be deactivated for at least 5 seconds.
FAN SPEED CONTROL To enable the unit to function correctly at different external temperatures, a microprocessor with reading of pressure via transducer controls fan rotation speed.This allows the exchange of heat to be increased and/or decreased, maintaining condensing or evaporation pressures more or less constant. The fan functions independently of the compressor.

SHUTTING DOWN FOR LONG PERIODS After deactivating the chiller: - Check that the remote switch SA1 (if present) is in the OFF position. - Check that the remote keyboard (if present) is set to “OFF”. - Place QF1 and QS1 in the OFF position - Deactivate internal units by placing the switch of each unit in the "OFF" position.
- Close the water valves. If there is a possibility that the water temperature may drop below zero, there is a risk of freezing.The hydraulic circuit MUST BE EMPTIED AND CLOSED or antifreeze must be added in the proportion recommended by the manufacturer.

ROUTINE MAINTENANCE Regular maintenance is fundamental to maintain the efficiency of the unit both in terms of operation and energy consumption.The Technical Assistance Service maintenance plan must be observed, with an annual service which includes the following operations and checks: -
Filling of the water circuit Presence of air bubbles in the water circuit Efficiency of safety devices Power supply voltage Power input Tightness of electrical and hydraulic connections
- Condition of the compressor contactor - Efficiency of the plate heat exchanger - Verification of operating pressure, superheating and subcooling; - Efficiency of the compressor heater - Cleaning of finned coil (*) - Cleaning of fan grills - Cleaning of condensate collection pan (if installed) (*) in the case of HRAN “Heat Pump” units, three-monthly. For units installed near the sea, the intervals between maintenance should be halved.

EXTRAORDINARY MAINTENANCE CHEMICAL FLUSHING You are recommended to chemically flush the plate heat exchanger after every 3 years of operation. For instructions on how to carry out this operation, contact the manufacturer. REFRIGERANT GAS CONTENT The chillers are filled with R22 (HRAT-HRAN models) or R407c (HRAT E) refrigerant gas and tested in the factory. In normal conditions, there should be no need for the Technical Assistance Service to intervene to check the refrigerant gas. However, over time, small leaks may develop at the joints leading to loss of refrigerant and draining of the circuit, causing the unit to function poorly. In this case, the leaks of refrigerant must be identified and repaired and the refrigerant circuit refilled in accordance with legislation in force in the country concerned on substances causing damage to the ozone layer and using special equipment to collect the refrigerant in order to protect the environment. Proceed as follows: - Empty and dry the entire refrigerant circuit using a vacuum pump connected to either the low or high pressure tap until the vacuometer reads about 10 Pa. Wait a couple of minutes and check that this value does not rise to more than 200 Pa. - Connect the refrigerant gas cylinder or a filling cylinder to the low pressure line pressure tap. 34

- Fill with the quantity of refrigerant gas indicated on the rating plate of the unit. - Always check the superheating and subcooling values. In nominal conditions, for the HRAT-HRAN models these should be between 6 and 10°C and between 4 and 6°C respectively, while for the HRAT E the values should be between 5 and 10°C and between 4 and 8°C respectively. - After a couple of hours operation, check that the liquid indicator indicates circuit dry (dry-green) Operating conditions other than nominal conditions may produce considerably different values. Seal testing or identification of leaks must be carried out using R22 refrigerant gas or nitrogen (HRATHRAN models) or R407C refrigerant gas (HRAT E models), checking with a suitable leak detector. The refrigerant circuit must not be filled with a refrigerant other than that indicated on page 17-18. The use of a different refrigerant may cause serious damage to the compressor. Oxygen, acetylene or other inflammable or poisonous gas must never be used in the refrigerant circuit as they may cause explosion or poisoning. Oils other than those indicated on page 17-18 must not be used. The use of a different oil may cause serious damage to the compressor. HRAT E - HRAT/HRAN
