SCHEMATIC DIAGRAM MP5N/MP7N OPEN TANK
On these units, there may be 1 or 2 pressure control valves.
When the network is heating, the pressure increases. The overflow valve(s) open then and the network water
goes into the tank. When the temperature and pressure decrease, the pump(s) start in order to reach the
required pressure. Level sensors into the tank allow the automatic tank filling and pump(s) stop if the water
level is too low inside the tank. The controller manages the pressure set point and eventual defaults.

SCHEMATIC DIAGRAM MP5N/MP7 CLOSED TANK
On these units, there may be 1 or 2 pressure control valves.
Same principle than open tank system except that the water level is calculated from the water weight inside
the tank. For this, a weight sensor is connected to an electronic card inside the control box. This card power
supplies the weight sensor and acquires its signal, translated into inner water level, replacing the standard
water level sensors.

HYDRAULIC CONNECTIONS
Specific to closed membrane vessel:
▪place the vessel in the heating room and install setting feet + sensor foot at the
opposite of pump unit at first. Check that it is stable and vertically + horizontally aligned.
If not, adjust the setting feet.
▪Then, install the air vent and the bottom collector on the expansion tank in line with
the pump unit.
•The tank storage must be at the same level or a higher level than the pump module. Connect the tank
to the pump module as per figures 15 and 17 on the previous drawings (MP4N/MP5N/MP7). On the
MP195NL, these connections are factory made.
If you are using 2 or more expansion vessels, they must be of the same size and
on the same ground level as shown bellow :
Open tanks :
Connect drain connection together.
Use a T plus gate valve for drain.
Tank2 not to be equipped with level
sensor and filling line.
Closed tanks :
Drain valve is OK for both tanks.
Use a T under tank1 and connect
second tank to it
Tank2 not to be equipped with
weight sensor nor control box.
FOR OPEN / CLOSED :
TANK 1 = TANK 2
•It is necessary that the expansion piping which connects the network to the module has an equal or
larger diameter than the pressurization unit’s.
•Connect the collector to the network (Rep.12 for MP195NL and Rep.16 on MP4/5/7) and deposit the
valve wheel. Respect an ascending slope towards the network and use a pipe diameter so that the
expansion flow has a speed lower than 0.1m/s.
•The optional expansion vessel must be connected to the fouling collector (Rep.16 on MP4N/5N/7).
Don’t forget the drain valve included in this option.
•Connect the cold-water input to the automatic tank filling line (Rep.2 on MP195NL Rep.1 on
MP4N/5N/7). This line can be horizontally or vertically placed.
•If you have a cartridge filter delivered as an option, it is important that you connect it before the
automatic filling line.
•Connect the overflow (Rep.11 on MP195NL Rep.12 on MP4N/5N/7) to the sewer.
SPECIFIC TO OPEN TANKS:
•Install the level sensors Rep.6,7 inside the tank (except on MP195N). Push these sensors on a
length of 12 centimeters.
Nota: The upper sensor is factory marked

ELECTRIC CONNECTIONS
•Connect the unit to the main power
•Connect the “alarms”
The French DTU 65-11 requires the stopping of the installation in case of:
•Lack of water
•Low pressure
•High pressure
Please also refer to your local rules.
All the default information is signaled on the display and is relayed by an inversor volt free contact
(see next page)
Main supply: 230V (+10/-10 %) –1 Phase –50 Hz + Earth
WIRING DIAGRAMS
ELECTRONIC VERSION –ALL MODELS
The diagram below shows the electric wiring of external components of a 2 pumps
pressurization unit. In case of 1 pump, just suppress the connections to relay R2.
Relays are used as follows:
- P1 and P2 for the 2 pumps (as per equipment)
- R1 for the general default relay
- P4 for the electrovalve
