Note:
This pumps runs as long as the ON/
OFF switch is switched ON.
1. Plug power cable in.
2. Switch pump on with the ON/OFF
switch.
3. Open pressure line (open tap or
spray nozzle).
4. Check to see that the water comes
out!
A
Caution!
With a closed pressure line do not let
pump run for more then 10 minutes,
otherwise there could be damage by
the water overheating in the pump.
6.2 Starting a pump with
Hydromat (HWA)
3
Note:
A pump with installed Hydromat is op-
erational as long as the ON/OFF switch
is turned ON.
The Hydromat
– starts the pump when water is re-
quired (when opening the discharge
line the water pressure falls off to
below the cut-in pressure);
– turns the pump off approx.
10 seconds after closing the dis-
charge line (water pressure increas-
es in the closed discharge line);
– turns the pump off to prevent dry
running when no water is pumped
(air in suction line).

Care and Maintenance

A
Danger!
Prior to all servicing:
1. Turn OFF.
2. Unplug.
3. Ensure that pressure is relieved
from the pump and connected ac-
cessories.
Service and repair work other than
described here must be left to quali-
fied specialists.

Danger of freezing

A
Caution!
Frost damages the pump and acces-
sories, as both always contain wa-
ter!
When there is danger of freezing,

dismount the pump and accesso-
ries and store at a frost-free loca-
tion (see below).
7.2 Pump Dismounting and
Storing
1. Turn pump OFF and unplug.
2. Open pressure line (open tap or
spray nozzle) and drain water com-
pletely.
3. Drain pump completely; to do so re-
move the drain plug from the pump
ENGLISH
4. Disconnect suction and pressure
lines from the pump.
5. Store equipment in a frost-free room
(at least 5 °C).

Troubleshooting Guide

Pump does not run:
 Pump not turned ON.
 Start pump at the ON/OFF
switch.
– Hydromat has cut out.
Press the reset button. 

If no water is pumped after ap-
prox. 10 seconds, press and hold
reset button until Water emerges.
– No mains voltage.
 Check cables, plug, outlet and
mains fuse.
– Mains voltage too low.
Use only extension cables with

sufficient lead cross section (see
"Technical Specifications").
– Motor overheated; motor protection
relay tripped.
 After cooling the pump will switch
ON again.
 Ensure sufficient ventilation,
keep vent slots clear.
 Observe max. temperature of the
pumped medium.
– Motor hums but does not start.
 With the motor switched OFF,
put screwdriver or similar through
the fan cover's vent slots and
turn the fan.
– Pump blocked or out of order.
 Disassemble pump and clean.
 Clean diffusor, replace if neces-
sary.
 Clean impeller, replace if neces-
sary.
