6. Inspection and Maintenance
Please heed the safety instructions in chapter 1.
The switch unit must be completely disconnected from the mains
for cleaning. When replacing the batteries, use 9-V Block. Repairs
may only be carried out by the manufacturer.
The switch unit does not require any maintenance.
The connection cables must be checked for damage. If any dama-
ge can be detected, the system must be put out of operation im-
mediately.
The sensor has to be cleaned at regular intervals.
Every time disposal takes place the sensor must be cleaned with
warm/hot water*. When a high-pressure jet cleaner is used, main-
tain a safe distance of 30 cm. The sensor does not have to be re-
moved for cleaning.
The sensor does not have to be removed for cleaning. The grease
separator must be filled with water after emptying.
* In the case of KESSEL D+SP, MS and PVS grease separator
systems, cleaning can wait until the next servicing date since the
separator is cleaned with warm water. If necessary (heavy sensor
soiling by strong hardening grease) carry out cleaning every time
disposal is carried out.
The control unit will only display a grease thickness layer 24 hours after being placed into operation due to the fact that the reading
is taken at night, "-" will be displayed until then.
