Sanyo 85464369098000 Checking After Installation, When Removing the Ceiling Panel for Servicing

Page 34

3-6-5. Checking After Installation

Check that there are no gaps between the unit and the ceiling panel, or between the ceiling panel and the ceiling surface. Gaps may cause water leakage and condensation.

Check that the wiring is securely connected.

If it is not securely connected, the auto flap will not operate. (“P09” is displayed on the remote controller.) In addition,

Xwater leakage and condensation may occur.

3-6-6. When Removing the Ceiling Panel for Servicing

When removing the ceiling panel for servicing, remove the air-intake grille and air filter, disconnect the wiring connec- tor inside the electrical component box, and then remove the 4 mounting screws.

3-6-7. Adjusting the Auto Flap

The air-direction louver on the ceiling panel outlet can be adjusted as follows.

Adjust the louver to the desired angle using the remote controller. The louver also has an automatic air-sweeping mechanism.

NOTE

Never attempt to move the louver by hand.

Proper air flow depends on the location of the air conditioner, the layout of the room and furniture, etc. If cooling or heating seems inadequate, try changing the direction of the air flow.

3-7. Special Remarks

DC Fan Tap Change Procedure

Be sure to turn OFF the power (at mains) before beginning the work below.

(1) In the table below, check the field-supply parts that will be used. (If this setting is not made, the airflow may decrease and condensation may occur.)

Setting

Air shield material (for use with 3-direction discharge)*

(a)

Air shield material (for use when a discharge duct is connected)*

(b)Air shield material (for use with 2-direction discharge)*

Setting (a): Go to (2).

Setting (b): Go to (3).

* Use field-supply air shield material.

(2)Setting (a)

Open the cover of the electrical component box. Short the short-circuit pin TP3 (2P, yellow) on the indoor unit control PCB. (Fig. 3-28)

(3)Setting (b)

Open the cover of the electrical component box. Short the short-circuit pin TP6 (2P, white) on the indoor unit control PCB. (Fig. 3-28)
