Installation and connection

NOTE

Excessive water pressure in the system will damage the unit.

Ensure that the distance from the highest water withdrawal point does not exceed 15 m.
Ensure that the system pressure does not exceed 10 bar.
Adhere to the maximum permissible pump pressure. It may be less than 10 bar

The unit can be connected horizontally or vertically at any point between the pressure connection of a garden pump, deep well pump or submersible pressure pump and the first water withdrawal point (e.g. washing machine).

Recommendation: Fit directly to the pressure connection of the pump. Use an adapter.

How to proceed:

Screw the adapter onto the pump.
– Ensure that the O-ring is correctly seated.
Screw the unit onto the adapter.
– When fitting, ensure that the arrow on the cover and the outlet of the unit point in the direction of the water flow.
Connect the unit to the downstream line

NOTE
Ensure that all connection lines are completely leak-tight, as leaking lines can impair the function of the system and lead to damage.

Use a suitable sealant to seal the threads of the lines and the connection to the pump.
Overtightening of plastic screw connections can lead to damage. Do not apply excessive force.

Operation

Starting up the unit

It is necessary to fill the pump and expel the air from the suction line before using. It can take several minutes to expel air from the suction line.
How to proceed:

Completely fill the pump and suction line. (Pump operating manual)

Disconnect the pump and ProMax Garden Automatic Switch from the power supply before working on the unit.

CAUTION

The lines are pressurized. Risk of injury caused by the water jet spurting out. Damage to the unit due to leaking water. Prior to starting work: Open the water withdrawal point to depressurize the system.
Measures after completing the work:

How to proceed:

Pull the power plug of the ProMax Garden Automatic Switch.
Pull the power plug of the pump.
Depressurise the pressure line by opening a withdrawal point.
Also open any non-return valves fitted in the suction line.
– When the pump is switched off, residual water in the hose may flow back and out of the pump intake.
If the pump is to be completely removed:
Proceed according to the pump operating manual.

Changing the cut-in pressure

WARNING
Risk of severe injuries or death by electric shock.

This work may only be performed by a qualified electrician.
Disconnect the pump and ProMax Garden Automatic Switch from the power supply before working on the unit.
Measures after completing the work:

How to proceed:

Observe the characteristic curve when adjusting the cut-in pressure.

Unscrew the housing and remove the cover.
Change the pressure setting by turning the adjusting screw with a screwdriver Observe the pressure characteristic curve.
Refit the housing cover and start up the unit again.
Read off the pressure at the pressure gauge and correct the pressure setting again if necessary.

The switch-off pressure is not adjustable and depends on the pump used in the system.

Maintenance and cleaning

NOTE
Do not use aggressive cleaning agents or chemical solutions. These agents can damage the housing, impair the function of the device and harm animals, plants and the environment.
