    SAFETY REGULATIONS Strictly comply with the following regulations to prevent injuries to the operator or damage to the machine. • This use and installation manual is an integral part of the machine. It must be kept with care and be ready to hand should the operators require it for consultation.
  • Page 12: Installation

    INSTALLATION Handling Check the weight of the appliance before proceeding with the moving and handling operations. The weight is indi- cated on the data plate of the appliance and in the “Main Features” section of this manual. Make sure that the appliance is handled with care and without jolting as rough treatment could damage the functional parts of the machine.
  • Page 13: Installation

    INSTALLATION Fig.1 Installation Use a fork lift truck to lift the appliance during the installation phase (Fig.1). Fig.2 Keep the appliance in a horizontal position without tilting it. Once it has been positioned, remove the packing materials (Fig.2). Good protection against the transmission of vibrations is obtained by placing blocks of resi- lient material (neoprene, etc.) between the bearing feet of the machine and the floor.

  • Page 15: Electrical Connections

    ELECTRICAL CONNECTIONS Description of the main components The appliance must be wired in compliance with the laws in force in the country where it is installed, at the time installation takes place. The units are supplied after having been fully wired in the factory and are pre-engineered for connection to the electricity main.
  • Page 16 ELECTRICAL CONNECTIONS General rules 1) Connection to the electricity main - Power supply line The power supply line of the machine must be installed in compliance with the current laws governing the instal- lation site in question. The power supply line of the machine must follow a well defined route that must be as short as possible and without interruptions.
  • Page 17 ELECTRICAL CONNECTIONS - Protection on supply side An automatic switch must be installed on the supply side of the above mentioned line in order to protect against any overcurrents and indirect contacts that could occur when the machine operates. It is advisable to install an automatic limiter switch to suit the minimum specifications given in the table above. Connections between the line and switch must be made in compliance with the current standards governing elec- trical safety matters, regarding the type of installation and environmental conditions in which the machine is instal- led.
  • Page 18: Wiring Diagrams

    ELECTRICAL CONNECTIONS Wiring diagrams The following pages contain the main wiring diagrams of the appliances. These diagrams show the connections required to power the machine, activate any supplementary loads (pump, electrical heating element and alarm indicator), connections with the available digital inputs (ON/OFF, summer/winter season changes and connection with the remote control panel).

Power supply: 230V-1-50Hz. 2.5 sq.mm wires of the H05 RN-F type or depending on the installation. See specific standards. 2: Terminal board in the machine.
  • Page 22: Wet Connections

    WET CONNECTIONS General rules Comply with the local laws governing safety matters in order to correctly design the hydraulic circuit. A gauze filter (hole Ø ≥ ≥ 500 µm) must be installed on the plate exchanger inlet in order to prevent foreign bodies from entering for versions of the appliance in which the accumulation kit is not to be used.
  • Page 23 WET CONNECTIONS Hydraulic layout of the circuit without accumulation kit Typical layout A diagram of connections to the hydraulic circuit of the unit is depicted in the figure below. IMPORTANT: There must be a constant flow of water to the exchanger. NOTE: 1) The water inlet in the unit is situated in the upper part of the unit itself and is indicated by a data plate.

  • Page 25 WET CONNECTIONS Connection using quick couplings (AV) The series of available accessories includes a wet connection kit with quick couplings. These couplings can be used to connect the chiller and the system or the chiller and the accumulation kit. They ensure an optimum seal even when the units are slightly misaligned and also limit the transmission of vibrations between the units themsel- ves.
  • Page 26: Load Losses

    LOAD LOSSES Load losses The graph below illustrates the load loss values in kPa depending on the flow rate in liters/second. The range is delimited by the minimum and maximum values given in the next table. Water flow rate (l/s) The load losses refer to an average water temperature of 10°C.
  • Page 27 USE OF ACCUMULATION KIT Primary circuit in the unit If the accumulation kit is used, the water flow towards the unit is guaranteed by the primary circulation pump, while water circulation around the system is ensured by a second circulation pump as shown in the diagram on page 19. Both circulation pumps are the three-speed type.

  • Page 30: Maximum Volume Of Water

    MAXIMUM VOLUME OF WATER Maximum volume of water in the system with accumulation kit Before filling the hydraulic circuit, it is worthwhile taking into account the type of installation, i.e. care must be taken to consider the difference in level between the wet module and the user. The graphs below give the maximum contents of the hydraulic circuit in liters of water depending on the capacity of the expansion tank which is part of the standard supply, and the pressure at which it must be charged.

  • Page 32: Monitoring System

    MONITORING SYSTEM User interface The monitoring system, which consists of a regulator with push button panel and display, is installed in the front part of the unit and can be accessed by opening the relative door. All users and the various monitoring components are connected to it by means of an interface board.

  • Page 34: Probe Reading

    MONITORING SYSTEM Probe reading The temperature setting (i.e. the temperature read by the probe on the exchanger inlet) expressed in degrees Centigrade (the temperature can be displayed in °F by changing the value of the H52 parameter from Ø to value 1) or the alarm code if at least one alarm is activated, are shown on the display during normal machine ope- ration.
  • Page 35 MONITORING SYSTEM MONITORING The monitoring functions allow the operating parameters of the unit to be selected. Operating modes 1. Operating mode key (MODE) The screen-printed design illustrates, with cyclic rotation, the operating mode to which the machine sets each time the key is pressed.
  • Page 36 MONITORING SYSTEM 3. MODE + ON/OFF keys The screen-printed design illustrates, with cyclic rotation, the meanings assumed by the mode and on/off keys when they are pressed at the same time. These keys allow you to access the menu and subsequent sub-levels if pres- sed for 1 second or to quit in reverse if pressed for 2 seconds.
  • Page 37: Alarms

    MONITORING SYSTEM ALARMS If faults occur during normal machine operation, the controller will stop the machine and display the code of the alarm relative to the activated safety device. After having checked the alarm and eliminated its cause, the user can reset the controller by pressing the on/off key.
  • Page 38: Menu Structure

    MONITORING SYSTEM 3. Menu structure The menu in the monitoring system has a tree structure based on four different levels. Level 0 includes the values the controller displays during normal operation, i.e. the thermoregulation temperature (temperature detected by probe "t01" on the exchanger inlet) or an alarm code. The menu where the seven labels (titles) are displayed can be accessed by moving up to level 1.
  • Page 39: Setting At Work

    SETTING AT WORK General rules To validate the contractual warranty, the machine must only be set at work by an authorized assistance center. Before it is called, check to make sure that all parts of the installation have been completed, that the unit is levelled, the plumbing connections made with the relative air vent and that the electrical connections have been made.
  • Page 40: Safety And Pollution

    SAFETY AND POLLUTION General considerations The machine has been designed to reduce the risks to persons and to the environment in which it is installed, to the minimum. To eliminate residue hazards, it is therefore advisable to become as familiar as possible with the machi- ne in order to avoid accidents that could cause injuries to persons and/or damage to property.
