responsibility for below mentioned cases of possible
damage caused by our devices:
Unproper repairs performed by unauthorized service repair
shops;
Using pump for a different purpose or failing to observe its
use according to the provisions;
Overloading of the pump by long-term operation;
Protection against Thermal Overloading
A sensor is built into the engine that automatically switches off
the pump if a certain temperature has been exceeded, and/or
it switches the pump on after it has been cooled. This
increases the service life of the pump quadruptly, and
prevents burning of the electric engine.
Protection against Overloading /Thermoswitch of the Engine
The pump is furnished with an engine thermoswitch. If the
motor is overheated, the thermoswitch switches the pump
automatically off. The cooling period makes approx. 25
minutes, thenafter the pump will be automatically switched
on again. If the engine switch is on, it is necessary to find
and remove the cause (see also “Troubleshooting”). The
data here given cannot be considered as instructions for
“home made” repairs, because the repair works require
specific professional knowledge and skill.
Therefore you have to contact customer service if any
failure occurs.
It is unconditionally necessary to secure good air
supply in order to prevent overheating of the pump!
Do not install the pump in too tight shifts, do not cover
it with anything!
Operation
Air pressure
Pull out the network plug.
Open the consumption valve, e.g. water main tap, so that the
water may be pressed out of the system.
Turn the protection lid on the bleeding valve in the down
direction (F).
Check the air pressure in the vessel with compressor and
device for tyre pumping.
The specified air pressure is 1,5 ± 0,3 bar.
Bleeding
Release the bleeding screw and let the possible closed air
escape.
(Fig. A; pos. 11)
Water Bubbles
Release the screw for draining water bubbles so that the
pump may be drained (Fig. A; pos. 7)
Vessel pressure
Switch off pressure set by the manufacturer is 3-4 bar after
completion of filling.
Setting pressure of the vessel (air) makes 1,5 ± 0,3 bar and it
should be regularly checked and modified (G).
Safety Instruction for Operator
Use the device only after you have carefully read Operating
Manual.
Observe all safety instructions mentioned in the Manual.
Behave responsibly against other persons
Instruction Step-by-Step
•
Connect the suction pipeline that complies with the
outlet connecting pipe with check valve (foot valve).
Tighten all threading connections by sealing band
(B)
•
After filling up remove the bleeding screw on the
back side of the pump and on the connecting line of
pressure pipeline. (Fig. A; pos. 1 and 11) Fill the
device up until the water exits from the bleeding
hole (E)
•
Make tight the bleeding screw and retight it again.
Then make tight the pressure pipeline and connect
it.
•
Connect the pump to the electric network.
Caution: When installing suction and pressure
pipeline on corresponding connection lines, the
corresponding thread shall always be tightened
carefully so that no damage occurs due to cracking of
the pump shell !
Caution: Careful sealing of thread connections
(A/B) and airless filling (E) of suction system – (suction
hose and pump shell) , will save you from trying to
perform suction that may often be unsuccessful!
Check the tightness of the foot valve (D) – Fill the
system according to the instruction (C) and pull the
suction hose out of the medium being repumped before
putting into operation for the purpose of checking (D) -
the liquid should not escape from the suction hose
now!
Important: Should the pump be out of operation for a
lomger period of time, the pipeline and the pump shell
must be unconditionally emptied.
