    1. Safety Precautions Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing. Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit for the model installed. The caution items stated here must be followed because these important contents are related to safety.
  • Page 4 WARNING During pump down operation, stop the compressor before remove the refrigeration piping. (Removal of compressor while compressor is operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.) After completion of installation or service, confirm there is no leakage or refrigerant gas.

    10. Installation Instruction 10.1 Indoor Unit 10.1.1 Selecting the Installation Location Indoor Unit Location for securing the mounting panel. Before choosing the installation site, obtain user approval. Do not install the unit in excessive oil fume area such as kitchen, workshop and etc. There should not be any heat source or steam near the unit.

  • Page 29: Installing The Indoor Unit

    10.1.2 Selection of Pipe and Heat Insulation Materials When using commercial copper pipes and fittings, observe the following: Insulation material: Polyethylene foam Heat transfer rate: 0.041 to 0.052 W/mK (0.035 to 0.045kcal/mh°C) Refrigerant gas pipe’s surface temperature reaches 110°C max. Choose heat insulation materials that will withstand this temperature.

  • Page 30: Drain Piping

    10.1.3.1.3 Drain piping Use commercial rigid polyvinyl chloride pipe (general VP-20 pipe, outer diameter 26 mm, inner diameter 20 mm) for the drain pipe. The drain hose (outer diameter 18 mm at connecting end, 220 mm long) is supplied with the indoor unit. Prepare the drain pipe picture below position.
  • Page 31 Once refrigerant piping and drain piping connections are complete, fill in the gap of the through hole with putty. A gap can lead to condensation on the refrigerant pipe, and drain pipe, and the entry of insects into the pipes. Attach the front panel and front grille in their original positions once all connections are complete.

  • Page 32: Concealed Installation

    10.1.3.2.4 Indoor unit installation Remove the front grille. Remove the 7 screws. Remove the upper casing (2 tabs). Remove the side casings (2 tabs on each side). Attach the indoor unit to the wall and secure using screws in 6 locations (M4 x 25L). Use drain pan edge for horizontal projection of the indoor unit.

    10.1.3.3.3 Changing upward air flow limit dipswitch Change the upward air flow limit dipswitch (SW2-4) to ON to limit the upward air flow. Remove the front grille. Switch the dipswitch (SW2-4) on the PCB in the electrical equipment box to ON. How to set and use the switch Switch number SW2-4...
  • Page 34 10.1.5.1 Checking for gas leakage Check for leakage of gas after air purging. 10.1.5.2 Insulating the refrigerant piping Attach the pipe after checking for gas leakage, described above. Cut the insulated portion of the on-site piping, matching it up with the connecting portion. Secure the slit on the auxiliary pipe side with the butt joint on the connection pipe using the tape, making sure there are no gaps.

  • Page 36: Outdoor Unit

    10.2 Outdoor Unit 10.2.1 Selecting the Installation Location Before choosing the installation site, obtain user approval. If an awning is built over the unit to prevent direct sunlight or rain, be careful that heat radiation from the condenser is not obstructed. There should not be any animal or plant which could be affected by hot air discharged.

  • Page 37: Evacuation Of The Equipment

    10.2.3 Connecting the Refrigerant Piping Decide piping length and then cut by using pipe cutter. Remove burrs from cut edge. Make flare after inserting the flare nut (locate at valve) onto the copper pipe. Align center of pipe to valve and then tighten with torque wrench to the specified torque as stated in the table. Do not overtighten, overtightening may cause gas leakage Piping size Torque...

  • Page 38: Piping Insulation

    Disconnect the charging hose from the vacuum pump and from the service port of the 3-way valve. Tighten the service port caps of the 3-way valve at a torque of 18 N•m with a torque wrench. Remove the valve caps of both of the 2-way valve and 3-way valve. Position both of the valves to “OPEN” using a hexagonal wrench (4 mm).
  • Page 39 10.2.8 Auto switch operation The following operations can be performed by pressing the “AUTO” switch. AUTO OPERATION MODE The Auto operation will be activated immediately once the Auto Switch is pressed. TEST RUN OPERATION (FOR PUMP DOWN/SERVICING PURPOSE) The Test Run operation will be activated if the Auto Switch is pressed continuously for more than 5 sec.
