Replacing the ET-LAD40 lamp unit

WARNING!

When replacing the ET-LAD40 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

The lamp units are consumable parts. The ET-LAD40 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 ET-LAD40 lamp unit.

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