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 vert 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
