• The rear of the unit can be fixed with screws at the points shown in the illustration as below. Be sure to install the supplemental

plate in accordance with the depth of the inner wall.

See Refrigerant piping under Exposed Installation.

1. Remove the front grille.
2. Remove 7 screws.
3. Remove the upper casing (2 tabs).
4. Remove the side casings (2 tabs on each side).
5. Attach the indoor unit to the wall and secure using screws in 6 locations (M4 x 25L).

• Use polyvinyl chloride adhesive agent for gluing. Failure to do so may cause water leakage.

1. Use drain pan edge for horizontal projection of the indoor unit.
2. Install the indoor unit flush against wall.

62

• Only item peculiar to this installation method are given here. See Exposed installation for additional instructions.

• Install the unit according to the instructions below. Failure to do so may cause lead to both cooling and heating failure

1. Allow enough space between the main unit and ceiling not to obstruct the flow of cool/warm air.
2. Place a partition plate between outlet and inlet sections.
3. Place a partition plate on the right side.
4. Change the upward air flow limit dipswich.
5. Use a movable lattice at the air outlet to allow the adjustment of cool/warm air flow direction.
6. Lattice size should be 70% or more of open rate.

1. Remove the front grille.
2. Switch the dipswitch (SW2-4) on the PCB in the electrical equipment box to ON.

63

• Insert the supplied drain hose 

 into the socket of the drain pan. 

Fully insert the drain hose until it adheres to a seal of the socket.

• Pour a glass of water into the drain pan.
• Ensure that water flows out from drain pipe.

1. Please make flare after inserting flare nut (locate at joint

point of tube assembly) onto the copper pipe.

2. Align the center of pipe and sufficiently tighten the flare

nut with fingers.

3. Further tighten the flare nut with torque wrench in

specified torque as stated in the table under
3. Connecting the Refigerant Piping in OUTDOOR UNIT.

• Check for leakage of gas after air purging.

64

• Attach the pipe after checking for gas leakage, described

above.

1. Cut the insulated portion of the on-site piping,

matching it up with the connecting portion.

2. 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.

3. Wrap the slit and the butt joint with the included

insulation sheet 

, making sure there are no gaps.

1. Leave the sensor securing plate, remove the front metal

plate cover.

2. Connecting the cable between indoor unit and outdoor

unit shall be approved polychloroprene sheathed

4 x 1.5 mm

2

 flexible cord. Type designation 245 IEC57 or

heavier cord.

• Ensure the colour of wires of indoor unit and the terminal

Nos. are the same to the outdoor's respectively.

• Earth lead wire shall be longer than the other lead wires as

shown in the figure for the electrical safety in case of the
slipping out of the cord from the anchorage.

• Secure the cable onto the control board with the holder

(clamper).

1. Insulate the joint of the pipes securely.

Incomplete insulation may lead to water leakage.

2. Push the pipe inside so it does not place undue force on the front grille .
