Electrical safety

When using electric appliances always observe the safety regulations applicable in your country to reduce the risk of fire, electric shock and personal injury. Read the following safety instructions and also the enclosed safety instructions.

Always check that the power supply corresponds to the voltage on the rating plate.

Connecting to the power supply

Check that the power supply and plug used in accordance with your appliance. Have a look at the rating plate on the appliance. Any changes should always be carried out by a qualified electrician.

Warning! This appliance must be earthed. If not properly earthed this appliance can cause an electrical shock. Be sure that the power supply outlet is earthed. If there is any doubt, have it checked by a qualified electrician.

Warning! Avoid contact with the terminals on the plug when installing (removing) the plug to (from) the power supply outlet. Contact will cause a severe electrical shock.

Replacing cables or plugs

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. Immediately throw away old cables or plugs when they have been replaced by new ones. It is dangerous to insert the plug of a loose cable in the wall outlet.

Using extension cables

Only use an approved extension cable suitable for the power input of the appliance. The minimum conductor size is 1.5 mm ^2 . When using a cable reel always unwind the reel completely.

2. INFORMATION

3. ASSEMBLY

Before carrying out any work on the pressure switch, disconnect the mains plug from the power supply.

Do not mount the pressure switch into the water inlet side of the pump.

The pressure switch must be in an upright position. If it is in any other position, the pressure switch cannot work correctly.

The pressure switch should be installed in ventilated and dry environment. It could be installed outside, provided having proper covering to prevent rain and wind.

Install the pressure switch (Fig. A, B)

1. Apply thread seal tape (Teflon tape) to the water inlet (3) connection.
2. Screw the water inlet (3) connection into the pump outlet, as shown on figure B.
3. Decide which hose diameter and hose connection system fittings you are going to use.
4. Apply thread seal tape (Teflon tape) to the water outlet (1) connection.
5. Screw the coupling (not included) on the water outlet (1).
6. Connect the mains plug of the pump to the power socket (4).
7. Connect the hose (not included) to the coupling.
8. Check that the hose has no kinks in it.

4. OPERATION

Never use the pressure switch while people are present in the water!

Only switch the power on or off with dry hands.

Switching on/off (Fig. A)

1. Check that the ON/OFF switch of the pump is in the 'O' position before connecting the pressure switch to the power supply.
2. Move the ON/OFF switch 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 of the pump into the position 'O' to switch the pump off.

The pressure switch has 3 LED indicators (6, 7, 8) which indicate the status of the pressure switch:

LED indicators Operating status
LED-power (6)	The pressure switch is connected to the power supply. The pressure switch is ready for use.

LED-failure (7)	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 (5) on the pressure switch.
LED-on (8)	The pressure switch has tripped, the socket is live. The pump is operating.

Reading the pressure (Fig. A)

The pipe pressure can be read on the pressure gauge (2). The black scale indicates the pressure in bar.

Setting the switch-on pressure (Fig. A)

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 (9). Every 360^ turn decreases or increases the switch-on pressure for approx. 0.2bar.

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

Finish operation (Fig. A)

When there is the risk of frost or if you do not use your pressure switch for a long time, please properly store your pressure switch.

1. Check that the ON/OFF switch of the pump is in the 'O' position.
2. Remove the mains plug from the mains.
3. Disconnect the mains plug of the pump from the power socket (4).
4. Unscrew and remove the pressure switch. Let the water drain, then rinse with clear water. Make sure that there is no water left.
5. Remove the water hose from the water outlet (1). Unscrew the coupling from the water outlet (1).
6. Clean and store the device (see 'Maintenance').

5. MAINTENANCE

Before cleaning and maintenance, always switch off the appliance and remove the mains plug from the mains.

Cleaning

NOTICE! Risk of product damage! Never submerge device in water while cleaning.

Do not use cleaning agents or solvents. Wipe the device using a dry cloth.

Storage and frost potection

The pressure switch and accessories that are not completely drained can be destroyed by frost. Completely drain the pressure switch and accessories and protect them against frost.

Keep this appliance in well-ventilated dry premises with temperature not going below +5°C.

When not in use, keep this appliance stored in a safe place out of reach of children.
