Installation Procedure

5. REFRIGERANT PIPING (As for outdoor piping, please refer to installation Manual of outdoor unit.)

Outdoor is precharged with refrigerant.

Be sure to see the Fig.1, when connecting and removing piping from unit.

For the size of the flare nut, please refer to Table 1.

Apply refrigerant oil at both inside and outsid of l flare nut. Tighten it band tight 3-4 turns then tighten it.

Use torque specified in Table 1. (Too much force may damage flare nut, causing gas leakage).

Check piping joints for gas leakage. Insulate piping as shown in Fig. below. Cover joint of gas piping and insulator 7 with seal.

6. INSTALLATION OF WATER DRAINAGE PIPE

(1) Install water drainage pipe

Pipe dia, shall be equal or larger than that of unit piping.(pipe of polyethylent; size: 25mm; O.D:32mm)

Drain pipe should be short, with a downward slope at least 1/100 to prevent air bag from happening.

If downward slope can't be made, take other measures to lift it up.

Keep a distance of 1-1.5m between suspending brackets, to make water hose straight.

1-1.5m

Slope over 1/100

Use the self-provided stiff pipe and clamp 1 with unit. Insert water pipe into water plug until it reaches the white tape. Tighten the clip until head of the screw is less than 4mm from hose.

Wind the drain hose to the clip using seal pad 9 . Insulate drain hose in the room.

Tape (White)

Self-provided stiff pipe

<Cautions for the drain water lifting pipe>

Installation height shall be less than 280mm.

There should be a right angle with unit, 300mm from unit.

(Note)

Clamp (accessory)

The slope of water drain hose (1) shall be within 75mm, don't apply too much force on it. If several water hoses join together, do as per following proceedures.

Over 100

Connect water hoses with a T joint.

Specifieations of the water hoses shall meet the requirements for the unit running.
