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.

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

COMMISSIONING
The installation and use instructions should be respected, and the factory settings remain unchanged.
•Open the different valves on the unit,
•Drain the pump(s)
•Closed tank collector : a gate valve plus a cap are located on the upper part, allowing to easily air venting
while commissioning the unit, to remove air from the collector. Once done, close the valve and screw the
cap.
•OPEN EXPANSION VESSELS ONLY: Set the level sensors inside the tank. For that, pull on the electric
cables until it doesn’t move any more. Then, push both cables 12 centimeters inside the tank. Screw the
stuffing boxes of each cable.
•CLOSED EXPANSION VESSELS ONLY: Before water filling starting up the unit, RESET THE VOLUME
VALUE if different of zero. The controler display should indicate the water volume inside the tank, so should
be at zero before water filling by pressing the OK key. The zero volume is done by accessing to the
Technician menu at line “Zero setting”. At this point, press + key, then + and – to confirm.
THE ZERO ADJUSTMENT MUST BE DONE WITH AN EMPTY VESSEL !
If it is not the case, power off the control box and open the drain valve located on the
collector to remove water. Once done, close the drain valve and power on the control
box.
•Check the expansion vessel pressure (about 0.1 bar less than the pressure set point). The setting must be
done without water into the vessel.
•Power on the unit by the main control panel. The first time, the controller indicates “lack of water” and opens
the electrovalve to start filling the vessel. Once the filling volume has been reached, the pump(s) start,
pressurizing the installation.
•As per the unit type, both pumps should start together if required pressure is not reached at the unit start
up. A cyclic permutation will shift the starting pump in order to have the same worked hours for each pump
(MP5/MP7 only).
•Check the starting pump pressures on the display compared to set pressure on the controller.

MAINTENANCE
Warning! Before operating on a unit, ensure that electrical supply of
the control box is OFF.
Only authorized people should work on the unit
The Cetetherm pressurization units require little maintenance. For that, you just have to check:
•The filter(s) is(are) clean,
•The overflow valve(s) operate correctly,
•The expansion vessel should be inflated 0.1 bar less than the pressure set point,
•There is no leakage and the unit is clean,
•The different settings and security functions,
•The pump(s) do(es) not require any particular maintenance.
Cut off the electrical supply before working on it

PRESSOSMART OPTIONS
1- Anti-hammer vessel (Ref. VASABMP01/ VASABMP02/ VASABMP03)
MP4N MP5N
MP7
2- Cold water inlet strainer (Ref. OPTMPFILT)
The strainer and its mounting accessories should be placed before the filling electrovalve on the
cold water inlet, as illustrated bellow :
Install a gate valve, eventually a bypass before the strainer.
Except MP4N models, the
vessel can be mounted on
the left or on the right side of
the collector, as per needs.

15
3- Filling water flow meter (Ref. OPTMPDETECT)
The flow meter and its accessories has to be installed before the filling electrovalve, as illustrated
bellow :
The left arrow represents the cold water inlet, filling the storage tank.
Install a gate valve before the flow meter.
Flow meter output is one (1) pulse every ten (10) liters.
Flow meter’ s electric wires must be connected to one of the two available C (common) and I3
terminals of the power board CI572P as per the electric wiring diagram shown below:
4- Room flooding sensor option (Ref. INONDMP)
This level sensor must be connected to one of the two available C (common) and I4 terminals of
the power board CI572P as per the electric wiring diagram shown below:

16
5- 8 relays optional card (Ref. OPT8RELAYMP). OPEN TANK ONLY.
The 8 relays’ card allows to report separately Pump 1, 2 (as per equipment), sensor defaults, low
pressure, high pressure, lack of water, network leakage and flooded room by actioning a specific
contact issued from a relay.
You still have general default relay on the power board.
Each default relay has an inverted contact, which can be normally closed (NC) or normally opened
(NO).
Mounting
If the card has not been factory mounted, please refer to following instructions.
Connect the card to point as shown below.
The extra card is fixed to the power board by 5 M3 screws . In the case you add this card in an
existing control box, please refer to the schematic diagram bellow.
