7. Operation procedures
7.1. Start up
Note:
before start.
7.2. New system
In order to ensure a problem-free start up of a new
Bleeding the pipe system
1. Turn on the water supply to rinse and bleed the
entire system. If satellites are installed open the
tap furthest away until no air or dirt comes out.
Then rinse and bleed the next tap and continue
until the tap closest to you has been rinsed and
bled.
2. Mount satellites, if any
Bleeding the pump
3. Loosen the relief plug (A) 1-2 revolutions until
Never loosen the relief plug while the pump
is running as this may damage the packing.
4. Tighten the relief plug again
5. Start the pump so that all remaining air pockets
are forced up to the top of the pump.
6. Stop the pump
7. Loosen the relief plug 1-2 revolutions again and
8. Tighten the relief plug once more
The booster is now ready for operation.
Press “I” on the control panel.
7.2.1. Long Stops
If long productions stops are planned (more than 6
months) and the pump is emptied of water, it is rec-
ommended that the pump be secured as follows:
1. Remove the coupling safety guard.
2. Spray a couple of drops of silicone oil onto
the axle between the top section and the
coupling.
6.7. Water Connection
• Before the unit is connected to the
water supply pipe, the supply line
should be rinsed carefully in order
to remove coarse impurities and
metal shavings.
• The connection for water must be
made at the top of the unit. (see
layout drawing).
• Minimum internal diameter of the
supply pipe must be at least 1 1/4”
external (ø36mm internal).
• The unit must be fitted with a clos-
ing valve for water on the inlet (see
drawing 110003601).
• The pressure loss in the supply line
must be held as low as possible by
- avoiding long supply pipes
- mounting low pressure resistance
ball valves and
- avoiding fittings with high pressure
loss.
• When installing the piping, take care
to avoid air traps.
• All pipe connections to the unit must
be screwed connections ensuring
simple maintenance and dismantling
of the station.
Max. allowed temperature of supply water: 70°C
Max. allowed pressure of supply water: 2-8 bar
For an optimum functioning we recom-
mend installing a filter on the inlet to
avoid impurities. Min. Filter mesh size
