Intended use
Check tests for pressure or air tightness of piping
systems and containers used in all types of
installations.
Hydraulic installations, heating facilities, compressed
air, steam, cooling, oil and sprinkler installations,
thermal solar systems, etc.
Manufacturing of boilers (coil air tightness check)
and pressurised recipients or tanks.
Circuit filling.
Routine maintenance
Before connecting the pump to the power and water
supplies:
Check carefully serviceability of h.p. hose and
cord with plug. If necessary, replace them with
new ones.
Check water filter (No. V121M37 - C Spare
Parts). Get it clean or replaced, if required.
If the equipment is going to remain unused for a
long period, we recommend that you empty out any
residual water from the internal circuits.
Avoid storing the equipment in very cold areas where
there may be a risk of freezing.
Maintain the water filter clean and in good
condition.
If you are using the equipment with Glycol or Tifocor-
type antifreeze products, switch the system on with
clean, fresh water in order to flush out the internal
circuits.

Repair, replacement of parts
For the most accessible sealing gaskets, there is a
maintenance kit (cod. R6.1186) which enables you to
change worn or degraded gaskets, thus extending
the electric pump’s working life.
Operating instructions
Open master bleeder (pos. B of the of outer
view) of the piping system to be tested (pos.
A).
Connect the water inlet hose (pos. F of the of
outer view) to the power pump. It is possible to
feed the testing power pump in two ways:
directly from the water network (min. 1 bar
pressure) – pos. E of the outer view,
from a tank placed max. 1 meter below the
level of the power pump (pos. D of the of
outer view).
Connect the high pressure hose (pos. C of the
of outer view) to both power pump and piping
system (pos. A).
Open the valve V2 towards OPEN. Turn the
valve V1 knob towards - bar till the its stop
point.
Put the plug (pos. I of the of outer view) into
its socket: the power must be 230 V, 50/60 Hz,
single phase. Switch on the power pump (pos.
G of the of outer view) and let it run until all air
has been drained from tested piping.
Switch the power pump (pos. G) off and close
the master bleeder (pos. B).
To submit the piping system to wanted test
pressure:
switch again the power pump on,
turn slowly the valve V1 towards +bar
increasing the pressure till wanted test
pressure is pointed out by the manometer
(pos. F of the of outer view),
close completely the valve V2 towards
CLOSED.
If you notice that the manometer points out a
pressure higher than the wanted one:
open fully the valve V2 towards OPEN and
open the valve V1 towards - bar till reaching
the wanted pressure,
close the valve V2 towards CLOSED,
switch the power pump off.
