AL-KO JET 4000 Traducción Del Manual Original De Instrucciones página 17

Start-up
2. Install the pump horizontally and where it will
not be flooded.
■
The pump must be protected from rain and
direct water jets.
4.2 Connect the suction line
NOTE We recommend the installation of
flexible lines at the pump inlet to prevent me-
chanical pressure or tension being exerted on the
pump.
1. Select the length of the suction line such that
the pump cannot run dry. The suction line
must always be at least 30 cm under the wa-
ter surface.
2. Connect the suction line. Ensure that the
connection is tight, but take care not to dam-
age the thread.
3. Always lay the suction line with an upward
gradient.
NOTE If the suction head is more than 4 m,
a suction hose with a diameter larger than 1"
must be installed. We recommend the use of an
AL-KO suction unit with suction hose, suction fil-
ter and flow-back stop. Ask your specialist dealer.
4.3 Install pressure line
1. Screw connecting nipple (15) with round seal
ring (16) into pump outlet (3).
2. Screw elbow nipple (13) with seal (14) onto
connecting nipple (15) and turn the elbow
nipple in the required direction.
3. Connect pressure line (12) to elbow nipple
(13).
4. Open all shut-off devices (valves, spray noz-
zles, water cock) in the pressure line.
5 START-UP
5.1 Fill the pump
IMPORTANT! Danger of damage to the
pump! Dry running will destroy the pump!
■
The pump must be filled with water up to the
overflow before each use so that it can draw
water immediately.
NOTE Fill the suction hose with water before
screwing in place to reduce the suction time.
1. Open the filling screw using the filter wrench.
2. Pour in water through the filling screw until
the pump housing is full.
3. Screw in filling screw.

6 OPERATION
6.1 Switching the pump on
1. Open all shut-off devices (valve, spray noz-
zle, water cock) in the pressure line.
2. Insert the plug of the mains cable into the
power socket.
3. Switch on the pump at the on / off switch.
IMPORTANT! Danger of damage to the
pump! A closed pressure line can result in dam-
age to the pump!
■
Do not allow the pump to run against a
closed pressure line.
6.2 Switching the pump off
1. Switch the pump off at the on / off switch af-
ter use.
2. Close all the shut-off devices in the pressure
line.
CAUTION! Danger of injury from hot wa-
ter After extended use against the closed pres-
sure side (> 10 min.), the water in the pump can
become very hot and may escape uncontrolled!
■
Disconnect the pump from the mains supply
and allow the pump and water to cool down.
■
Put the pump into operation again only after
all the faults have been remedied!
The risk of injury from hot water can arise in the
event of:
■
Incorrect installation,
■
Closed pressure side,
■
Lack of water in the suction line, or
■
Defective pressure switch.
Procedure
1. Disconnect the pump from the mains supply
and allow the pump and water to cool down.
2. Check the pump, installation and water level.
3. Put the pump into operation again only after
all the faults have been remedied!
