Filter operating hour counter

The operating hour counter of the

grease filter is set at the factory to a

certain number of operating hours. This

time can be altered as required.

When the pre-set time has elapsed, the

control lamp above the grease filter

switch comes on. The grease filter

should then be cleaned.

The operating hour counter must then

be re-set to the time previously se-

lected when the filter was last used.

Press the grease filter switch for ap-

prox. 4 seconds.

The control lamp will go off.

The percentage of operating hours in

which the filter has already been used

in relation to the time set in the opera-

ting hour counter can be displayed as

follows:

Switch the fan on using the On/Off

switch.

Press the grease filter switch.

The number of control lamps flashing

on the –/+ switch indicates the percent-

age of operating hours in which the fil-

ter has already been used in relation to

the number set in the operating hour

counter:

1 lamp = 25 %

2 lamps = 50 %

3 lamps = 75 %

4 lamps = 100 %

The number of operating hours for

which the filter has already been used

is stored in the event of mains failure.
