• You cannot stop the operation while the air intake grille is lowering.

* If you press the ( ) button while the air intake grille is moving down, the air intake grille may stop lowering, but it will not stop immediately.

• By default, the air intake grille will automatically stop at the lowering distance of 1.6 m from the ceiling level.

* The distance can be changed to 1.2 m, 2.0 m, 2.4 m, 2.8 m, 3.2 m, 3.6 m, and 4.0 m.

These should be used only as a guide. You should lower the air intake grille yourself to check the exact distance.

• You cannot stop the operation while the air intake grille is rising.

1) Ensure that the air-conditioner is not running.

* The up/down operation mode is only available when the air-conditioner is "OFF".

2) Press both the "FILTER" and "Ventilation" buttons simultaneously for 2 seconds or more to enter the up/down operation mode.

3) Press the "Ventilation" button. After a while, it will switch to the "individually-specified up/down operation mode".

4) If you press the "FILTER" button when the "Unit No." or "Refrigerant address No." is blinking,

the up/down airflow direction of the displayed air-conditioner will be switched downward after a while, and the airflow direction of the other vents will all be blocked.

5) Select the "Unit No." and "Refrigerant address No.".

■"Unit No." and "Refrigerant address No." can be changed by using the "TEMP." buttons ( ) ( ) when the panel displays (a) or (b).

■Every time you press the "Mode selection" button, the target of operation will change as illustrated below.

6) Continue to press the "Mode selection" button until "Waiting for up/down operation" is displayed.

The following steps are the same as steps 3) - 6) described in the "General Operation" section. Refer to that section.

■In Step 5) described below, identify the target air-conditioner by changing the "Unit No." and

"Refrigerant address No." and by pressing the "FILTER"

button to check the up/down airflow direction.

■Each pressing action changes the unit No. from "1 - 4" to "0".

(Unit No. "0" means that all of 1 - 4 are targeted.)

■Each press changes the "Refrigerant address" from "0 to 15".

■If "Err" is displayed when you press the "FILTER" button to check the target air-conditioner, the air-conditioner with that "Unit No." or "Refrigerant address" may not exist. Check and set that air-conditioner again.

Fig.1 Detection

switch

(1) Normal operation

UP/DOWN

Air intake grille is raised/lowered by commands of UP and DOWN.

Air intake grille does not move under the state of no-load detection or obstacle detection.

Air intake grille stops automatically at the set lowering distance from the ceiling level.

STOP

It stops in the cases below :

• When it reaches at the set lowering distance from the ceiling level.

It automatically stops after a predetermined period of lowering.

• When it is stored in the panel.

The air intake grille is judged to be stored in the panel

when the storage detection switch is pressed for 3 seconds continuously.

• When receiving commands of STOP, DOWN while moving up or UP while moving down.

The STOP button is only available on the automatic filter elevation panel remote controller.

When the wired remote controller is used, there will be a slight delay in stopping due to transmission speed.

• When both wire 1b and wire 2b are not loaded.

Only the wire b in each UP/DOWN Machine has a tension detection switch.

(2) Special operation

Storage operation

Case : Obstruction of the raising grille before storage or malfunction of storage detection switch Storage operation will be performed when the intake grille has been raised the set distance but the storage detection switch is not engaged.

In this case, the operation below will be repeated up to 4 times.

10 cm down 30 cm up ···· 10 cm down 30 cm up No-load detection

Case : UP/DOWN commands with no grille suspended.

When both wire 1b and wire 2b are not loaded, the wires will not move.

Obstacle detection

Case : Making contact with something while lowering.

Should the loads on the wire 1b and wire 2b be removed due to the grille making contact with something while lowering, the lowering operation will stop. The grille will then be raised 10 cm and stop again.

[Emergency operation]

• When the wireless remote controller cannot be used (in the case of battery discharge, misplacing of the wireless remote controller, malfunctioning and so on), the emergency switch on the receiver can be used as an alternative.

* When doing this, particular caution must be taken not to fall.

To lower the air intake grille : Press the button once.

(For emergency heating operation, press and hold this button.) To raise the air intake grille : Press the button once.

(For emergency cooling operation, press and hold this button.)

• To stop the air intake grille from moving, use the opposite buttons to those used to initiate movement.

(To stop it from lowering, press the UP button; To stop it from rising, press the Down button.)

• If up/down machine is out of order, fix air intake grille temporarily and the indoor unit can be operated.

* For details, refer to installation manual for the attachment of grille.
