The Watermanager GWM should be operated in this state until all building works are finished. We do not recommend connect-
ing the greywater inlet permanently with the system if building works are still being carried out in the building. We recommend
installing a bypass of the greywater line directly into the sewer for this period.
Step by step commissioning:
I.
The greywater line is not connected to the coarse filter Trident, no greywater is entering the greywater buffer
tank/BMT-unit.
II.
If necessary, pump out any stagnant or dirty water from the greywater buffer tank/BMT-unit into the drain. Fill up
greywater buffer tank/BMT-unit completely with drinking water using a hose. If the BMT-membrane filter was only
partly submerged in water please contact immediately your contractual partner or DEHOUST.
III.
Connect the control unit with main power supply.
IV.
Switch on control unit.
V.
Switch into mains water operation (
Mains-water
) by pressing the function key (A) at the control unit.
VI.
Mains water back up system starts automatically and refill the process water storage tank.
VII.
Switch to Automatic-operation (
Automatic
) by pressing the function key (A) at the control unit.
VIII.
One-off manual set-up of the filtration capacity on the tacosetter of the BMT-unit according to the predefined maxi-
mum filtrate drain (see sticker attached directly to the tacosetter). Please heed chapter 0 for manual set-up of the fil-
tration capacity.
IX.
Switch into mains water operation (
Mains-water
) by pressing the function key (A) at the control unit.
X.
Open a process water consumer (e.g. toilet flush, tap). Close the process water consumer when water is discharged
without air pockets.
XI.
The system is ready to operate in mains-water-operation.
On this step the process water consumers will be served via the mains water back up system and not with
receycled greywater.
Heed the
operating manual GWMt
!
Heed the manual for the booster pump station!
During
Mains-water
operation the greywater is ventilated by the air compressor. Without mains water in the tank
the operation will lead to severe damages at the components ( air compressor).
The
Watermanager GWM
should be operated in drinking water mode until the building has an occupancy rate of at least 25%.
Efficient bacteria culture only develops in the
Watermanager GWM
when greywater is supplied daily in a sufficient volume.
The steps explained in the previous chapter (see 6.2) must have been complied in advance.
I.
Check sieve plate of coarse filter and remove all residues and waste.
II.
connect the greywater inlet with the coarse filter
III.
Put activated carbon and dry bacteria into the greywater buffer tank/BMT-unit.

Step 1: commissioning to mains water
– without greywater inflow

Step2: commissioning to mains water with greywater inflow
