Remote Alarm Terminal, AIR Intake Port

REMOTE ALARM TERMINAL

The terminal of the remote alarm is installed at the lower left side of the unit. The alarm is outputted from this terminal. Contact capacity is DC 30V, 2 A.

Contact output:

	between COM. and N.O.	between COM. and N.C.
At normal	Open	Close
At abnormal	Close	Open

Note:

•The alarm buzzer is silenced by pressing alarm buzzer stop key (BUZZER) on the control panel during alarm condition. (A remote alarm is continuing the operation.)

The buzzer will be activated again after certain suspension if the alarm condition is continued.

•The alarm is actuated when the power supply plug is disconnected from the outlet or the power switch is OFF.

AIR INTAKE PORT

When a door is closed and opened soon, a door does not sometimes open this product.

The warm air which went into the chamber is cooled down rapidly, and this is because air inside the chamber contracted.

When a door is closed and opened soon, a door is easy to open with the following process.

1.Turn the cap of the left side counterclockwise, and remove it.

2.Put the air into the chamber from about ten for twenty seconds, and open a door.

3.Close a cap if a door opens.

Cap

A door may not open in the above method when there are frost and ice in the air intake port. In that case, open a cap, and investigate the matter whether there is no frost inside the air intake port. Remove frost inside the air intake port in "the air intake port cleaning stick" of the accessories when there is frost. Clean a air intake port every month even when there is no frost inside the air intake port. Refer to page 22.

WARNING

For removing the frost of the air intake port, do not use a tool with sharp edge such as a knife or a screw driver.
