Appendix Piping Connection 1. Form the piping according to its routing. Avoid bending and bending back the same piping point more than three times. (This will result in hardening the pipe.) 2. After deforming the piping, align centers of the union fitting of the indoor unit and the piping, and tighten them firmly with wrenches. 3. Connect pipe to the service valve or ball valve which is located below the outdoor unit. 4. After completing the piping connection, be sure to check if there is gas leakage in indoor and outdoor connection. Vacuum drying After completing the piping connection, execute vacuum drying for the connecting piping and the indoor unit. The vacuum drying must be carried out using the service ports of both the liquid and gas side valves.

HEAT INSULATION Appendix 1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over 120°C). Fastening band (accessory) 2. Precautions in high humidity circumstance: This air conditioner has been tested according to the "KS Standard Conditions with Mist" and confirmed that there is not any default. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than 23°C), water drops are liable to fall. In this case, add heat insulation material according to the following procedure: • Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20mm. Indoor unit Refrigerant piping Thermal insulator (accessory) • Stick glass wool on all air conditioners that are located in ceiling atmosphere. • In addition to the normal heat insulation (thickness: more than 8mm) for refrigerant piping (gas piping: thick piping) and drain piping, add further 10mm to 30mm thickness material.
