Structure Figure 1: Principle structure of the Watermanager GWM The actual system may deviate from the basic set-up. Please see specific set-up diagram! 3.6. Intended use The Watermanager GWM must only be operated in those fields of use described in this manual. -
Page 11: Improper Use
All pallets/components must be stored in a dry, cold room protected from both sunlight and frost. When delivering goods, check every packing unit for damage. In case of transport damage, determine the exact damage, doc- ument it and report it immediately in writing to the contracting party or DEHOUST. -
Page 12: Installation/Assembly
5. Installation/Assembly 5.1. Installation room The Watermanager GWM must be installed at ground level and horizontally in a frost-free, dry and well-ventilated room. The load bearing capacity of the floor must be at least the total weight of the Watermanager GWM in its filled operating state (750 kg/m²). - Page 13 Figure 2: Connection of the coarse filter Trident MAX I Make sure the overflow line to the sewer/pumping system has the same nominal width as the overflow connec- tion (no cross-section constriction!). 5.3.2. Backflushing line of the coarse filter Connect the back-flushing line (see 3.3) firmly, tightly and in a de-energised state with a branch line of the process water line. Figure 3: Connection of the backflushing line of coarse filter MAX I and MAX II We recommend installing a shut-off valve and a detachable screw.

Page 14: Overflow Of The Tanks
5.4. Overflow of the tanks The overflow connections of the coarse filter and those of the greywater and process water storage tanks are designed to be flat pipe connections and must be connected with the drain. You must ensure that no greywater can flow into the process water storage tank when connecting the overflow connections from the greywater and process water storage tanks with the drain. -
Page 15: Air Compressor And Filtrate Lines
5.5. Air compressor and filtrate lines Connect the appropriately marked tank connections firmly, tightly and in a de-energised state using the supplied PVC hoses and the preassembled PP hose nozzles. Fit the mounting bracket of the air compressor in direct proximity to the greywater buffer tank/BMT-unit on a supporting concrete wall using the supplied assembly accessories. -

5.6. Installation of submersible booster pump into process water storage tank Only in associations with submersible booster pump! The submersible booster pump has to be installed on site. Connect the HDPE-pipe via quick-connector on the pressure outlet of the booster pump. Open the process water storage tank and place carefully the booster pump on the tank bottom. Connect the other side of the HDPE-pipe with the corresponding quick connector at the tank. - Page 17 Figure 8: connection of HDPE-pipe and tank connector Figure 9: electrical connection of the booster pump...

5.8. Process water line Connect and seal the process water line/suction line of the pressure booster with the threaded sleeve connection (see 3.3) of the Watermanager GWM. Figure 11: Connection of the process water pipe with integrated submerged booster pump Figure 12: Connection of the process water pipe with extern booster pump station Connect the suction line in a de-energised state. -
Page 20: Emergency Overflow Due To Type Ab Drinking Water Feed
5.9. Emergency overflow due to Type AB drinking water feed If a backflow occurs due to a drain blockage/defect of the lift pumping station, reaching into the process water storage tank of the Watermanager GWM, the water is drained through the side emergency overflow slit of the process water storage tank into the installation room. -

Page 23: Potential-Free Alarm Output
5.11. Potential-free alarm output It is possible for a general error message to be sent to a central control unit by connecting a potential free output (max. 230 V / 5 A) to the control unit. The error message output of the control unit has a break contact (open in case of alarm). The error mes- sage remains open until it has been manually deactivated in the control unit (please see Operation manual GWM). -
Page 24: Extern Alarm Input
5.12. Extern alarm input It is possible to include an extern alarm sign (24 VDC) via potential free output to the control unit. The error message output of the control unit has a break contact (open in case of alarm). The error message remains open until it has been manually deac- tivated in the control unit (please see operation manual GWM). -
Page 25: Commissioning
6. Commissioning Only allow qualified personnel to commission the system (see 1.6). The commissioning of the Watermanager GWM has to be done in four steps: Step 1: Commissioning at MainsWaterMode (control unit set to Mains-water) – without connection to the greywater downpipe (bypassing) –... -
Page 26: Step 1: Commissioning To Mains Water - Without Greywater Inflow
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. -
Page 27: Step 3: Commissioning To Automatic-Operation
Run system for next 2 weeks in this mains-water-mode to establish a strong bacteria culture. The wastewater-typical microbiology is established independently within 1 to 1½ weeks with continual greywater inlet. Until then, deviations can occur in the biological cleaning capacity. 6.4. -
Page 28: Extended Periods Of Downtime
If the downtime of the system is longer than 4 weeks, then we recommend a supporting inoculation of microbiology with dry bacteria when the treatment process is recommenced. Please do not switch of the control unit during a downtime period to keep a sustain and strong microbiology. Please contact your contractual partner or DEHOUST. -
Page 29: Repairs
7.1. Inspections If an inspection yields faults/damage in the Watermanager GWM, then you should contact your contracting party or DEHOUST. 7.1.1. Trident coarse filter screen plate To inspect the screen plate, the lid of the casing (secured by 4-6 wing screws) of the coarse filter is opened. Remove any stub- born, coarse impurities, which could not be removed by the spray nozzles, from the screen plate using a cleaning brush. -
Page 30: Maintenance
For these reasons it may happen that the BMT-membrane filter has to be exchanged before the regular maintenance interval. The exchange of the BMT-membrane filter has to be done by a contracting party or DEHOUST. Please heed the corresponding manual for BMT-membrane filter exchange and software update. - Page 31 The maintenance is carried out allowing for and following the instructions of the maintenance log for greywater systems! Disconnect the Watermanager GWM from the electricity grid during maintenance and repair work. Heed the operation manual GWM as well! Heed the manual for BMT-membrane filter exchange and software update as well!
