Intended use
The pressure increase pump for MELAdem47 enables the increase of the inlet pressure of the water treatment unit
MELAdem47.
The MELAdem47 can thus produce higher quantities of demineralized water (DI water) at low line pressure on the build-
ing side. The pressure increase pump is installed by trained service technicians. After the installation, the operation of
the pressure increase pump is automatic. The pressure increase pump must be operated together with the
MELAdem47. User groups and usage environment correspond to those of MELAdem47. The pressure increase pump
is intended for use in the medical field, e.g. in clinics, medical and dental practices outside the patient environment.

4 Installation
Tools required: Allen key (4mm), open-end wrench (SW10, SW12, SW19, SW27), Phillips screwdriver (PH2), water-
pump pliers, hose cutter
The following must be fulfilled or present:
ü The line pressure is at 1-6bar.
ü The cold water inflow and the shut-off valve of the pressure tank of the water treatment unit are closed.
ü The water treatment unit is pressure-free.
1. Loosen the two screws on the front of the water treatment unit.
2. Pull out the cover hood upwards.
3. Remove the cold water inflow hose from the water tap or water
stop.
4. Remove the cold water inflow hose from the water treatment unit.
5. Remove the brass double nipple (¾") from the inflow of the water
treatment unit.
6. Install the straight screw-in fitting into the inflow of the water
treatment unit. Slightly tighten the straight screw-in fitting.
7. Mount the PUR hose of medium length on the straight screw-in
fitting.
8. Slide the osmosis module slightly to the right.

4 Installation
9
9. Remove the two screws on the filter housing of the fine filter.
10. Lead the PUR hose of medium length through the recess to the
pump.
11. Attach the pressure increase pump to the water treatment unit
using the two screws that were previously loosened.
12. Connect the PUR hose of medium length to the output side of the
pressure increase pump.
13. Cut the PUR hose approximately in the middle between the mixed-
bed resin cartridges and the switchover valve.
14. Insert the pressure switch at the point where it was cut.

4 Installation
10
15. Lead the pressure increase pump cables under the osmosis
module. Connect the cables to the pressure switch.
16. Push the osmosis module back to the left into the initial state.
PLEASE NOTE
When inserting the dirt filter, pay attention to the flow direction on the dirt filter.
The arrow on the dirt filter must point in the direction of the pressure increase pump.
17. Attach the short PUR hose directly behind the dirt filter.
18. Attach the other end of the short PUR hose to the T-piece of the
pressure increase pump on the input side.
19. Attach the long PUR hose to the other end of the dirt filter.
PLEASE NOTE
The installation of a leakage water detector with cut-off valve (e.g. the water stop from MELAG) is
recommended.
20. Connect the other end of the long PUR hose to the MELAdem
direct connection on the water tap or water stop.
21. Check all hose screw connections on the water treatment unit for
tightness.

tank and restart the water treatment unit.
23. Insert the power plug of the pressure increase pump into a
socket.
24. Check the water treatment unit for correct function and leakages.
25. Replace the cover hood when the water treatment unit is
functioning correctly and fasten the cover hood with both screws.

5 Operation

5 Operation
Initial commissioning
The following must be fulfilled or present:
ü No leakages were detected.
1. Check the delivery volume to the pressure tank: Disconnect the hose to the pressure tank. Lead the hose into a
suitable measuring cup. The delivery volume must be 280-350ml/min.
2. Perform empty sterilisation with the connected (combination) steam sterilizer. MELAG recommends using a
reprocessing program with the highest possible water consumption.
3. Check the conductivity with the use of the connected (combination) steam sterilizer or a measuring device. The
conductivity must not exceed 5µS/cm. If conductivity is poor, replace the mixed-bed resin cartridge in the ion
exchanger.
4. Close the pressure tank shut-off valve. The pressure increase pump and the water flow into the drain must stop at
the latest after 30s.
5. Check the function of the optional electronic leakage water detector (water stop).
Daily operation
uAfter the initial commissioning, the operation of the pressure increase pump is automatic.
uPerform a daily visual and functional check of the pressure increase pump.
uNever operate the device unattended (e.g. overnight). Unsupervised operation of the device can result in damage to
the device or your facility and is performed at your own risk. In such a case, MELAG does not accept any liability.
