Installation CAUTION: Install certainly the decorative panel. Cool air leakage causes sweating. Water drops fall. Good example Air conditioner unit Bad example Air conditioner unit Air Cool air leakage (no good) Ceiling board Decorative panel Fit the insulator (this part) and be careful for cool air leakage HEAT INSULATION Ceiling board Decorative panel 1. Use the heat insulation material for the refrigerant piping which has an excellent heat- resistance [over 120°C(248°F)]. 2. Precautions in high humidity Fastening band (accessory) 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 Refrigerant piping it is operated for a long time in high Indoor unit humid atmosphere [dew point temperature: more than 23°C(73.4°F)], Thermal insulator (accessory) 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. • Stick glass wool on all air conditioners that are located in ceiling atmosphere. Drain Piping [Standard /Artcool Mirror Type] 1. The drain hose should point downward for optimum drainage. Downward slope 2. Incorrect Installation Examples: Do not raise Accumulated drain water Air Water leakage Water leakage Kinking 32 Multi Air Conditioner Tip of drain hose dipped in water Water leakage Ditch Flexible drain hose Less than 50mm (1 31/32 inch) gap
