Replacing the lamp unit

WARNING!

When replacing the lamp, allow it to cool for at least one hour before handling it.

•The lamp cover gets very hot, and touching it can cause burns.

Make sure that two lamp units are always installed.

Precautions on lamp unit replacement

Remove the power plug and confirm that the surroundings of the lamp unit have cooled off.

Be careful when handling a light source lamp. The lamp unit has high internal pressure. If improperly handled, explosion might result.

A used lamp unit may burst if it is handled violently.

For disposition of used lamps, request an industrial waste disposal contractor. If you continue to use a lamp after the replacement time, the lamp may break. Phillips screwdriver is necessary when replacing a lamp unit.

Take care not to slip your hand when using a screwdriver.

Note • It is not possible to turn on the power unless two lamp units are installed.

•A lamp unit is an optional part. Contact the dealer.

Replacement lamp unit model No.: ET-LAD40 (single bulb), ET-LAD40W (double bulbs)

•Other lamps than specified above cannot be used. Be sure to use the specified lamp.

When to replace the Lamp unit

The lamp units are consumable parts. The lamp brightness decreases gradually as the cumulative operating time increases, so periodic replacement is necessary. The replacement guideline is 3 000 hours, although the lamp may become dead (will not light) before 3 000 hours is reached depending on the characteristics of individual lamps and other factors such as the operating conditions and the installation environment. Therefore, it is recommended for the user to keep a spare lamp unit.

The risk of the lamp bursting increases after 3 000 hours of operation, so the lamp unit turns off automatically.
