To change the up/down airflow direction

PFFY-NEMU-A

While pulling the blowout grill out toward you, raise the rear, remove it, change the
direction, and set it in place.

Caution:

Avoid putting your hand into the air outlet of the indoor unit any more than
necessary during operation. If you get your hands caught in the metal parts
when adjusting the airflow-direction-adjustment board and blowout grill, or
nip them in the autovane, there is a risk of injury and failure.

3.6. Time setting

Set the current time after turning ON the power of the air conditioner or after
restoration from a power failure.

It can be set regardless of the operation of the indoor unit.

During the time operation, the time-setting button becomes void, disabling time

About 10 seconds after the button operation has been completed, the C “cur-
rent time” and A “CLOCK” displays disappear.

Caution:

Remote controller is equipped with a simplified clock with a precision of
about + or - one minute per month.

The time must be readjusted (reset) every time the air conditioner is sub-
jected to a power stop of the air conditioner or a power failure.

3 [selecting operation] button and bring up the “FAN” display.

The fan operation functions to circulate the air in the room.

The temperature of the room cannot be set by fan operation.

Caution:

Never expose your body directly to cool air for a long time. Excessive expo-
sure to cool air is bad for your health, and should therefore be avoided.

Dry operation
The dry is a microcomputer-controlled dehumidifying operation which controls ex-
cessive air-cooling according to the room temperature of your choice. (Not usable
for heating.)

1. Until reaching room temperature of your choice

The compressor and indoor fan function is linked motion according to the change
of the room temperature and automatically repeat ON/OFF.

2. When reaching room temperature of your choice

Both the compressor and indoor fan stop.
When stop continues for 10 minutes, the compressor and indoor fan are oper-
ated for 3 minutes to keep the humidity low.

For heating

Press the 3

3

3 [selecting operation] button to bring up the “HEAT” display.

Regarding displays during heating operation “DEFROST”
Displayed only during the defrosting operation.

“STAND BY”
Displayed from the start of heating operation until the moment warm air blows out.

Caution:

When the air conditioner is used together with burners, thoroughly ven-
tilate the area. Insufficient ventilation can result in accidents due to oxy-
gen deficiency.

Never place a burner at a place where it is exposed to the airflow from the
air conditioner.
Doing so can result in imperfect combustion of the burner.

The microcomputer functions in the following cases:

Air does not blow out when heating starts.
- To prevent any cool air from escaping, the indoor fan is gradually switched in

sequence from faint airflow/weak airflow/set airflow according to the tem-
perature rise of the blown out air. Wait a moment until the airflow comes out
naturally.

The fan is not moving at the set speed.
- In some models, the system switches over to faint airflow when the tempera-

ture of the room reaches the set temperature. In other cases, it stops to
prevent any cool air from escaping during the defrosting operation.

Air flows out even if operation is stopped.
- Approximately 1 minute after the stop of operation, the indoor fan sometimes

rotates to eliminate extra heat generated by the electric heater, etc. The fan
speed comes to low or high.
