STORAGE<br />
ADVICE<br />
In the event of frost risk, the system must<br />
be drained completely (pump, lines and<br />
storage vessel).<br />
1. Drain the suction line (Fig. B -16) and pressure<br />
line(Fig. B -10).<br />
2. Unscrew the drain screw (Fig. A -8) and allow<br />
the water to drain from the pump.<br />
3. The water in the storage vessel (Fig. A -6) is<br />
pushed out at the same time by the air bellows.<br />
Storage<br />
4. Screw the drain screw (Fig. A -8) back in position<br />
and store the pump, lines (Fig. B -10,<br />
16) and storage vessel (Fig. A -6) in a frostfree<br />
location.<br />

Pump drive motor<br />
does not run<br />
Pump not drawing<br />
water<br />
Pump switches<br />
on and off too frequently<br />
Impeller blocked<br />
Overheating by dry running or water<br />
that is too hot (thermal protection<br />
switch has switched the pump off).<br />
No mains voltage<br />
The suction line is not under the water<br />
surface. Dry run, automatic switch-off<br />
after 90 seconds.<br />
Suction-side blockage<br />
Pressure line closed off<br />
Pump drawing air in the suction line<br />
Pump has been running dry<br />
Diaphragm is damaged.<br />
Low air pressure in storage vessel<br />
Clean the pump<br />
Release the motor shaft of the impeller<br />
with a screwdriver.<br />
Check the water level on the suction<br />
side.<br />
Allow the conveying fluid to cool down.<br />
Repairing or replacing the pump.<br />
Check the fuses and power supply.<br />
Submerge the suction line in the water<br />
by at least 30 cm.<br />
Remove dirt from suction area.<br />
Open the closing off units in the pressure<br />
line.<br />
Check all connections on the suction<br />
line for leaks.<br />
Replacing the seal.<br />
Fill the pump housing with water.<br />
Have the diaphragm replaced by <strong>AL</strong>-<br />
<strong>KO</strong> Service Department.<br />
Top the air up in the storage vessel.<br />
(Set the diaphragm pre-pressure to 1.5<br />
bar).<br />
