Mounting the handle (Fig. D )

1. Put the handle (7) on the pump, as shown on figure D.
2. Mount the handle (7) by tightening the two screws.
   

Installing the pressure switch ( Fig. E )

1. Screw the coupling into the pump outlet (6), as shown on figure E1.
2. Screw the water inlet (9) connection into the coupling, as shown on figure E2.
   
   

Installing the pump (Fig. G)
The pump should be installed in ventilated and dry environment. It could be installed outside, provided having proper covering to prevent rain and wind.
Make sure the pump is placed on the horizontal and stable ground. Always put up the garden pump at a point higher than the water surface, as shown on figure G.

Attaching the suction hose (Fig. A, F, G)
Don’t use any hose connection system fittings or standard water hoses on the suction side! A suction hose (8) set with suitable coupling (G1″ external thread) and foot valve (4) must be used. The foot valve (4) prevents the return flow of the water at the end of the pumping process.

25mm, 32mm or 38mm (inner diameter) suction hose (8) must be used to achieve maximum flow rate.
The suction hose (8) should be as short as possible.

1. Remove the protection cap from the water inlet connection.
2. Fill suction hose (8) with clean tap water, as shown on figure F.
3. Apply thread seal tape (Teflon tape) to the threaded suction hose coupling.
4. Screw the suction hose coupling airthight into the water inlet (3).
5. The foot valve (4) must be placed vertically and at least 30 cm from the water bottom to prevent the suction of sand and stones, as shown on figure G.

Attaching the outlet hose (Fig. B)
The larger the hose and hose connector diameter, the greater the flow.
The lower the delivery height, the greater the flow.

1. Decide which hose diameter and hose connection system fittings you are going to use.
2. Apply thread seal tape (Teflon tape) to the water outlet (10) connection.
3. Screw the coupling (not included) on the water outlet (10).
4. Connect the hose (not included) to the coupling.
5. Check that the hose has no kinks in it.

Filling the pump with water (Fig. A, H)

1. Unscrew and remove the filling plug (5).
2. Fill the pump with clean tap water, as shown on figure H. Do not overfill the pump.
3. Place the filling plug (5) back, do not overtighten.
   

OPERATION

Never use this pump in a pond or swimming pool while people are present in the water!
Only switch the power on or off with dry hands.
Never run this pump before the pump and the suction hose (8) is filled with water.
Clean the foot valve (not included) and pre-filter (not included) at regular intervals, and check it for damage. Otherwise, its function can be impaired.

Switching on/off (Fig. A)

1. Check that the ON/OFF switch (1) of the pump is in the ‘O’ position before connecting the pressure switch to the power supply.
2. Move the ON/OFF switch (1) of the pump into the position ‘I’ to switch the pump on.
3. With the pressure switch you can automatically control the operation of a garden pump. Open the connected tap or spray gun to start the pump. When you start the pump, there will be a lot of air in the water first. This is not a defect of your pump, but serves to remove air from the pump. It may take several minutes for the air to escape when the pump is used for the first time.
4. When you close the connected tap or the spray gun, the pump automatically stops pumping.
5. Move the ON/OFF switch (1) of the pump into the position ‘O’ to switch the pump off.

The pressure switch has 3 LED indicators (13, 14, 15) which indicate the status of the pressure switch:

pressure switch is ready for use.
LED-failure (14)| The pump is running dry without water. The dry-run safety is activated. Use the pump’s operating manual to find the cause of the failure and correct it. Then restart the pump by pressing the reset button (12) on the pressure switch.
LED-on (15)| The pump is operating.

Reading the pressure (Fig. B)
The pipe pressure can be read on the pressure gauge (11). The black scale indicates the pressure in bar.

Setting the switch-on pressure (Fig. A, B)
The default switch-on pressure is 1.5 bar. The switch-on pressure can be adjusted to a value between 1.5 bar to 2.5 bar.

It is possible to set the switch-on pressure by using the pressure setting screw (16). Every 360° turn decreases or increases the switch-on pressure for approx. 0.2 bar.

• By turning clockwise, the pressure will be increased.
• By turning anti-clockwise, the pressure will be decreased.

Finish operation (Fig. A, I)
Do not touch the pump unless its power has been cut off for at least 5 minutes.
When there is the risk of frost or if you do not use your pump for a long time, please properly store your pump.

1. Check that the ON/OFF switch (1) is in the ‘O’ position.
2. Remove the mains plug from the mains.
3. Unscrew and remove the drain plug (2). Let the water drain.
4. Pull up the suction hose (be aware, it is full of water).
5. Unscrew the suction hose (8) from the water inlet (3).
6. Remove the filter and foot valve (4), then rinse with clear water. Make sure that there is no water left in the suction hose (8).
7. Remove the water hose from the water outlet (10). Unscrew the coupling from the water outlet (10).
8. Place the drain plug (2) back, do not overtighten.
9. Clean and store the device (see ‘Maintenance’)
