    CAUTION: when sizing the pipes, make sure not to exceed the maximum pressure drop on plant side reported in the technical data table in Paragraph 0 (see useful head). CAUTION: connect the pipes to their fittings always using the key to key method. CAUTION: The return pipe from the system must be installed near the label “WATER INLET”...

  • Page 14: Filling The System

    Gasket Gasket Hole in bottom panel of outdoor unit Drain fitting Each unit is therefore fitted with a hole on the base of the hydronic kit (on the coil side) to drain condensation which could drip from the pipes of the plumbing system. Since these pipes are well insulated, a minimum amount of condensation is produced anyway and therefore it is not mandatory to connect a drain pipe to this fitting.

  • Page 15: Air Venting Valve

    6.4.6 Air venting valve The unit is fitted with an air venting valve to automatically remove air that has built up in the circuit, preventing undesirable effects such as premature corrosion and wear, lower performance and low exchange output. The device also features a safety function because, in the event of exchanger breakdown, it allows the refrigerant gas to escape outside, preventing it fro being conveyed to the internal terminals.

  • Page 23: Switching On The Unit

    CAUTION: The unit must be connected to the electric mains and placed in STANDBY (powered on) by closing the master switch at least 12 hours before start-up. This will allow the heaters to adequately warm up the compressor crankcase (the heaters are powered automatically when the switch is closed). The heaters are working properly if after a few minutes the temperature of the compressor crankcase is 10-15°C higher than ambient temperature.

  • Page 24: Maintenance And Periodic Checks

    10 MAINTENANCE AND PERIODIC CHECKS CAUTION: All the operations described in this chapter MUST BE CARRIED OUT BY QUALIFIED PERSONNEL ONLY. Before performing any intervention on the unit or accessing internal parts, make sure you have disconnected power. The heads and delivery pipe of the compressor are normally quite hot. Be careful when working near the condensing coils.

  • Page 25: Cleaning The Finned Coil

    10.1 CLEANING THE FINNED COIL To correctly clean the coil, follow the instructions below: a) Remove any superficial filth. Debris such as leaves, fibres etc. must be removed without a vacuum cleaner (use a brush or another soft tool carefully avoiding scratching with metal or abrasive parts). If you use compressed air, pay attention to keep the air flow perpendicular to the surface of the coil in order not to bend the aluminium fins.
  • Page 26 An incorrect decommissioning of the appliance may create serious environmental damage and endanger people’s safety. Therefore, it is recommended that the unit be disposed only by authorised persons with technical training who have attended training courses acknowledged by the competent authorities. It is required to follow the same precautions described in the previous paragraphs.

  • Page 28 Measurement Completed Notes Trigger Sources ■ Never use ignition sources, which could ignite the refrigerant, when carrying out operations on the cooling circuit which contains, or contained, flammable refrigerant. Remove all possible sources of ignition, including cigarettes, from the area where installation, repair, dismantling or disposal operations are being carried out, which may lead to a leak of refrigerant.
  • Page 29 Measurement Completed Notes Repairs on sealed connectors ■ During operations on sealed components, completely isolate the device from the power supply, before removing the sealed covers. ■ If, during operations, the power supply is absolutely necessary: Position a continuously operating refrigerant detector in the most critical places, so that it emits a warning signal in case of potentially dangerous situations.
  • Page 30 Measurement Completed Notes Leak detection The following leak detection methods are suitable for plants with flammable refrigerant: Leak detection by electronic refrigerant leak detector: ■ Electronic refrigerant leak detectors may not have the required sensitivity or may need to be calibrated for the relevant range. Perform the calibration operations in an area free of refrigerant.
  • Page 31 Measurement Completed Notes - The cylinders must be kept vertical. - Make sure that the refrigeration system is grounded before proceeding to recharge the system with the refrigerant fluid. - Label the system when charging is complete, (if not already done). - Particular care must be taken not to overload the refrigeration system.
  • Page 32 Measurement Completed Notes refrigerant fluid storage). The cylinders must be complete with a pressure relief valve and associated shut-off valves, in good working order. The cylinders of Empty cases are collected and, if possible, cooled before recovery takes place.
