5. FINISHING

Install the insulated pipes so that they do not touch the compressor.

5.1. Installing insulation

• Install insulation material after conducting "3.6. Sealing test".

• To prevent condensation and water droplets, install insulation material on the refrigerant

pipe. (Fig. A)

• Refer to the table to determine the thickness of the insulation material.

* When the ambient temperature and relative humidity exceed 89.6 °F (32 °C) (DB) and

85% respectively, strengthen the heat insulation of refrigerant pipe.

5.2. Filling with putty

Fill the piping holes and wiring holes with putty (locally purchased) to avoid any gap

(Fig. A). If small animals such as insects enter the external unit, a short circuit may be

caused near electrical components in the service panel.

• If the outdoor unit is installed at a level that is higher than the indoor unit, the water

that has condensed in the 3-way valve of the outdoor unit could travel to the indoor

unit. Therefore, use putty in the space between the pipe and the insulation to prevent

the entry of water to the indoor units.

6. HOW TO OPERATE DISPLAY UNIT

6.1. Display unit position

Never touch electrical components such as the terminal blocks except the button on

the display board. It may cause a serious accident such as electric shock.

• Once refrigerant charging is completed, be sure to open the valve prior to

performing the local settings. Otherwise, the compressor may fail.

• Discharge any static electricity from your body before touching the push buttons.

Never touch any terminal or pattern of any parts on the control board.

• The positions of the buttons on the outdoor unit control board are shown in the

following figure.

• Various settings can be adjusted by changing push buttons on the board of the outdoor

unit.
