6.4 Maintenance work at fixed service intervals
The following sections contain a description of the maintenance work to be
carried out at fixed service intervals. This work is listed in table 6.2 on page 56.
To retain your warranty entitlement, BOGE recommends that you have this
work carried out by certified BOGE service personnel using original spare
parts.
NOTICE!
If the cooling unit is excessively soiled (cleaning is no longer possible with
compressed air), have it disassembled and cleaned by BOGE customer
service.
NOTICE!
The service life of the cooler depends on the level of contamination and hard-
ness of the cooling water. In the event of excessive contamination, check the
cooling unit correspondingly earlier.
