Installing the Indoor Unit

◆Install Indoor Unit

Notes:

If the connecting cable is not long enough, please contact your distributor for a piece of special cable with sufficient length. No joints are allowed in the middle of the cable.

•Be sure to connect the cable correctly. Incorrect connection will cause fault to some electrical parts.

•Tighten the terminal screw.

•After tightening the screw, gently pull the cable for tightness.

•Incorrect connection of grounding cable might cause electric shock.

•Be sure to fit the junction cover plate securely and press it closely against connecting cable. Improper fitting of junction over plate might allow dust or water to enter or expose connecting terminal directly under the external force, fire or electric shock might occur.

•Fitting pipe can come out from one of four directions, i.e. right, rear right, left and rear left.

1.When laying the pipe (line) at the left or right side

cut as needed the extra part of the fitting pipe left at the tube-exit plate of the unit base. (See Fig. 9).

(1)When only drawing out the power line, cut extra part 1.

(2)When drawing out the connecting pipe and the electrical line, cut extra parts 1 & 2 (or 1, 2 & 3).

2.Pull out the fitting pipe from bottom case. Use adhesive tape to bond the fitting pipe, electrical cable and drain hose properly together and then pass them through the fitting pipe hole (See Fig. 10).

3.Hang the claws at the rear side of the indoor unit to the hook on the wall-mounting frame. Move the unit left and right to see if it is steady. (See Fig 11)

4.The installation height of the indoor unit must be at least 78.74in.

Installing Connecting Pipe

1.The taper end of the connecting pipe must be in line with the corresponding tape face of the valve joint.

2.Use enough force to manually tighten the nut of the connecting pipe and then use spanner to tighten the nut.

	Hexagon Nut (mm)	Tightening Torque
	Hexagon Nut (mm)	（N.m）
		（N.m）
	φ6.	15~20
	φ12	50~55

Notes:

Connect the connecting pipe to the indoor unit first and then connect it to the outdoor unit. Pay attention to the bending and layout when preparing the connecting pipe in order not to harm it. Do not screw the joint nut too tight, otherwise leakage will occur.
