INSTALLATION OF OUTDOOR UNIT

• A. The outdoor unit may be placed on a balcony. Make sure to put it in a vertical position and levelled. During the installation do not kink the connection tube between the units. Verify the correct air circulation around the outdoor unit.
• B Or fixed to the window sill.
• C Or hanged to the wall below the window sill using the support bracket kit (not supplied). After placing the unit in the support, check that it is levelled.
• D Insert the support in the handle of the outdoor unit, and turn the outdoor unit upside down (see the picture). Place the support and secure it at the edge of the unit. Insert the support guide fixed on the unit at the wall. Make sure it is levelled.
• E Do not handle the outdoor unit improperly.
• F When recovering the outdoor unit after operation drain away any remaining condensate by tilting the unit.
• G Place the indoor unit against the wall next to an electric socket.

WALL INSTALLATION (THROUGH A HOLE IN THE WALL)

IMPORTANT: OPERATION TO BE EXECUTED BY COMPETENT OR QUALIFIED PERSONEL

1. Before disassembling the outdoor unit (disjoin the rapid couplings): connect the air conditioner to a socket and let the compressor work for 5 minutes. During the disassembling operation, beat lightly with a spanner on the rapid coupling brass body (exagonal part).
2. Lubricate the joint surfaces (rapid coupling) with a little bit of HAB oil only (synthetic oil Alkylbenzene type ex. EXXON ZERICE S ).
3. When you disjoin the outdoor unit, follow the described succession: first, disconnect the power supply of the air conditioner (disconnect the plug), disconnect the electric connector, then the pipes of the frigorific connection.

• A Choose the best position where to install indoor unit. Mark the hole to be made in the wall.
• B Drill a 50 mm diameter hole, insert a PVC pipe.
• C Remove the coupling cover of the outdoor unit.
• D Disconnect the condensate plastic tube and the electric connector.
• E Loosen the quick coupling using the 19-21 mm spanners first and then the 19-24 mm spanners. Unscrew the flare nuts by hand and disconnect the flexible tube.
• F Protect quick coupling (on flexible tube and outdoor unit) with plastic plugs supplied as accessories.To insert the tubing into the hole in the wall easily and without damages, join the pipe ends and wrap them with adhesive tape.
• G Insert the flexible tube into the hole drilled in the wall. Place the unit against the wall, if necessary, adjust the four antivibration supports in order to keep the unit levelled.
  • NOTES: The four antivibration supports are rubber made and they could mark the floor; in this case the application of proper material under the support is recommended or use the supplied felt pads.
• H The unit can be placed on a balcony or hanged to the wall using the support bracket kit (not supplied).
• I Drill the holes and fix the support to the wall using the rawl plugs.
• L Remove the plastic plugs from quick couplings, connect the couplings by hand, then tighten using the torque wrenches (tightening torque 150 ÷ 165 kgcm).
• M Connect the condensate plastic tube and the electric connector.
• N Fix the coupling cover of the outdoor unit and seal the hole in the wall around the flexible tube.

HOW TO CONNECT THE FLEXIBLE TUBE EXTENSION KIT

IMPORTANT: OPERATION TO BE EXECUTED BY COMPETENT OR QUALIFIED PERSONEL

• A Carefully unroll the extension tube; be careful not to twist or kink it.
• B Remove the plastic plug from the extension tube ends (preformed tube side).
• C Fit the copper tubes on the support bent side. Connect the couplings by hand, adjust carefully the tubes on the unit top, then tighten using the torque wrenches (tightening torque 150 ÷ 165 kgcm).
  • NOTE: When disconnecting or reconnecting the flexible tubes, always use two proper wrenches: one to hold the fixed part and one to screw/unscrew.
  • WARNING: Do not lift the tubes when operating on the couplings as it may damage the tubes and lead to refrigerant leakage.
• D Connect the condensate plastic tube and the electric connector.
• E Fix the coupling cover of the outdoor unit.
• F Remove the plastic plugs from the opposite end of the flexible tube and connect quick couplings, first by hand and then using the spanners. Cut the PVC tube (soft kind) in excess then insert it into the stiff one.
• G Open the quick coupling box.
• H Adjust the couplings in the box, connect the electric cable connector then turn it by 180°. Place the electric cable and fix it to the pipe with the smallest diameter through hose clamps. Fix the gaskets on the connections box ends.

REMOTE CONTROL

REMOTE CONTROL UNIT INSTALLATION

To ensure that the air conditioner operates correctly, DO NOT install the remote control unit in the following places:

• In direct sunlight.
• Behind a curtain or other places where it is covered.
• More than 8 m. away from the air conditioner.
• In the path of the air conditioner airstream.
• Where it may become extremely hot or cold.
• Where it may be subject to electrical or magnetic noise.
• Where there is an obstacle between the remote control unit and the air conditioner.

WALL-MOUNTED POSITION

• Momentarily place the remote control unit in the desired mounting position.
• Verify that the remote control unit can operate from this position.
• Fix the support at the wall with two screws and hang the remote control unit.

MAINTENANCE OF THE REFRIGERANT CIRCUIT

Notes: IMPORTANT FOR MAINTENANCE

Make sure there is no heat source or potential heat source in the maintenance area. Open flames are forbidden in the maintenance area and the “no smoking” sign must be hung.

• Verify that the warning sign is in good condition, otherwise replace it. Refrigerant recovery in case of maintenance or removal of the unit
• If it is necessary to cut and weld the refrigeration circuit pipes during maintenance operations or to empty the refrigerant circuit in the event of removal of the unit, carry out the following operations:
  1. Turn off the unit and disconnect the power supply.
  2. Recover the gas.
  3. Make a vacuum with the vacuum pump.
  4. Clean the pipes with N2 gas.
  5. Cut and weld or bring the unit to the Service Center for welding.
  6. Make a leak detection check.
• The refrigerant must be recovered in the appropriate storage tank for R32 gas.
• Ensure that there is no naked flame near the vacuum pump outlet and that the area is well-ventilated.

Charge of the refrigeration circuit

• Refrigerant charge apparatus, vacuum pump, hoses and adapters must be exclusively used for R32. Make sure that different types of refrigerant do not contaminate each other.
• It is suggested to charge the refrigerant in a LIQUID state. Make sure that the refrigerant is the one required.
• Do not add any OIL to the compressor because precharged oil is specially selected for R410A.
• The refrigerant tank should be kept upright during the filling of the refrigerant circuit.
• Stick the label on the system after you finish the refrigerant charge.
• Do not overfill.
• After completing the charge, check for leaks before doing the test run.

MATCH BETWEEN REMOTE CONTROLLER AND THE UNIT

The remote control can be addressed to use up to 4 different units installed in the same room. You can get unified control by using a single remote control for all units or each remote control can be addressed to its own unit, in order to control separately temperature, timer and all other functions.

PCB SETTING

• Disconnect the unit power supply and wait at least 60 seconds, making sure that all the lamps go off.
• Remove the rear panel and the cover of the electrical box to access the PCB.
• Set JP2 and JP3 as shown in the table.
• Close the cover of the electrical box and the rear panel.
• Reconnect the unit power supply.

REMOTE CONTROLLER SETTING

• Press the button for a few seconds.
• Press the arrow until you visualize 06.
• Press the button again for a few seconds: the number 0 (factory setting) at the bottom starts flashing.
• Press the arrow to set 1, 2 or 3.
