4.4 Motor protection
Thermal protection of motor incorporated in winding; automatic
reset.
4.5 Dry-running protection
We recommend protecting it by a suitable device (float switch,
pressure switch, control box).
4.6 Operating principle
The pump in operation discharges water into the bladder, compres-
sing the air in the tank. When the max. pressure set is reached, the
pump stops.
The air presses on the bladder, driving water into the distribution
pipe when a tap is opened.
When enough water is drawn off for the minimum pressure to be
reached, the pump starts to deliver water and refill the bladder.
The pressure contactor (item 7) automates the operation of the
booster; the pressures can be read on the pressure gauge.
The reserve of water in the bladder means that water can be
drawn without starting the pump.
5. INST LL TION
5.1 Room
The booster must be installed in a shelter or in a room that is easy to
reach, normally ventilated, and protected from frost.
5.2 Installation (See FIG. 1)
Install on a smooth, level floor or on a concrete foundation block with
attachment by anchor bolts.
Place an insulating material (cork or reinforced rubber) under the
concrete block to prevent any transmission of flowing-water noise.

JET SYSTEM
5.3 Hydraulic connections
Water supply
By hose reinforced by spiral wrap, or by pipe.
The booster can be supplied with water, from:
- a well - take caution to max. suction height of the pump;
- a storage tank.
It is essential to fit a foot valve-strainer in the case of a well or
stream.
The diameter of the suction piping must never be less than that of the
pump. Limit the horizontal length of the suction piping and avoid all
causes of losses of head (necking, bends, etc.).
No air leak can be allowed in this suction piping.
With rigid piping, use supports or collars to avoid having the pump
bear the weight of the piping.
Distribution
By Ø 1" - 26/34 threaded piping connected to the brass coupling on
the pump outlet.
Thoroughly seal the piping with suitable products.
Bear in mind that the altitude of the place of installation and
the water temperature may reduce the suction head of the
pump.

To isolate the booster and allow adjustments and other work,
place valves (quarter-turn or similar) on the suction and dis-
tribution piping.
5.4 Electrical connections
The electrical connections and checks must be done by a
qualified electrician in accordance with the standards in
force.
Power supply network
Single-phase 230 V: connect using the cord (H07RN-F or equivalent)
with normalised plug (See FIG. 1 - item 6).
DO NOT FORGET TO CONNECT THE E RTHING LE D!
n electrical connection error would damage the motor. The
cord must never touch the piping or the pump, and must be
kept away from all moisture.
6. ST RTING UP
C UTION! Never run the module dry, even briefly.
6.1 Pressurization of tank
Check the tank pressure and correct if necessary by pressurizing via
the tank valve (See FIG. 1 - item 9).
The pressure must be 0.3 bar less than the pump starting pressure.
6.2 Remplissage - dégazage
Filling, degassing
- Close the discharge valve.
- Unscrew and remove the filling plug.
- Gradually open the suction valve and proceed to fill the pump
completely via the filling port.
- Screw the filling plug back in only after water has flowed out and
all air has been eliminated.
Pump in suction
Only one filling is enough for priming the pump.
- Open the discharge valve (item 12).
- Open the suction valve (item 11).
- Unscrew and remove the filling plug (item 2).
- Using a funnel inserted in the port, fill the pump slowly and comple-
tely.
-
fter water flows out and all air has been eliminated, filling is com-
plete.
- Screw the plugs back in.
6.3 djustment of pressure contactor (FIG. 3 and 4)
the adjustment of pressure contactor is made at factory. But it's pos-
sible to change it.
Proceed as follow:
- Unscrew the nut (item 1) of the differential.
-
djust the pressure of starting of the pump on the nut (item 2).
-
djust the variation of the differential (item 1) to obtain the impact
pressure of the pump.
NOTE: the selection of the points of starting and stop pump
must be compatible with the operating range of the contac-
tor (See FIG. 4).
7. M INTEN NCE
- The motor bearings are lubricated for life.
- The mechanical packing needs no maintenance in the course of
operation.
- In frosty weather and for prolonged stoppages of the pump, it must-
be drained by unscrewing the bottom plug.
C UTION! Fill the pump before using again.
Do not let the pump run more than a few minutes with the
discharge valve closed.
