N O T E !
The location for the cooler must remain frost-free, even when the
unit has been switched off!
If the cooler unit is putting out of action for a short time no particular measures need to be taken.
We recommend sweeping the cooler with inert gas or ambient air while the unit is putting out of action
for a longer time.

Aggressive condensate is possible.

18 MAINTENANCE
The safety instructions specific to the plant and process are to be consulted prior to any maintenance
work!
W A R N I N G !
It is necessary to take the cooler off the mains before any
assembly, maintenance or repair work is carried out!
The EC-EX cooler unit does not require any special maintenance intervals.
Depending on the quality of the ambient air the cooling fin block should be blown out with compressed
air from time to time.
When using automatic condensate removal by means of peristaltic pumps, the hoses of the peristaltic
pumps must be checked every three or six months, depending on the operating conditions, and
replaced if necessary. The procedure for changing the hoses is given in the corresponding operating
instruction SR25.1/Ex (Appendix).
