E Commissioning
The work described below may only be performed by trained ex-
perts. We recommend to have the start-up performed by Grünbeck's
technical service/authorised service company.
Warning!
Risk of bacterial growth due to stagnation! According to
VDI 6023, filling the system with drinking water before normal opera-
tion commences is prohibited.
The demanganisation system GENO-mat MN-Z must therefore only
first be connected to the drinking water system immediately prior to
commissioning.
1 | How to start up the system
1. Open the valve on the raw water inlet.
2. Open the valve at the pure water outlet.
3. Perform a visual check. Ensure that no water leaks from the sys-
tem at any point.
4. Rinse out fine particles
The filter material contains a small amount of fine particles which
must be flushed by means of a backwash prior to start-up. Initiate
a manual regeneration
(refer to chapter F, item 1.4).
Note:
The backwash process must be repeated until the backwash
water that flows to the drain in the process step "first filtrate" is clear.
5. Take a water sample at the sampling valve downstream of the
unit.
6. Determine the manganese concentration using the water test kit.
7. Complete the cover sheet and column 1 in the operating log.
