Function

The Hydrocontrol is an electronic pressure switch with integrated dry running protection and backflow stopper. It serves to convert a surface pump into a domestic water pump.

Functions of the pressure switch

Automatic operation of the pump

When a shut-off device in the pressure line is opened, the pump is automatically switched on by the pressure switch. When the shut-off device is closed, the pressure switch switches off the pump again once the maximum pump pressure is reached.

Protection of the pump against dry running

The pressure switch is equipped with a safety device that switches off the pump in the event of a lack of water.
The pump is switched off after approx. 45 s, signalled by the lighting up of the “Failure” LED.

The constant delivery rate and pressure

The pressure switch ensures a constant delivery rate with constant pressure.

The functioning range of the pressure switch

ON pressure: approx. 1.8 bar OFF pressure max.: 8.0 bar (or maximum pressure of pump)

Intended use

The appliance is intended for private use in the house and garden. It may only be operated within the framework of the operating limits indicated in the technical data.

The appliance is suitable for:

Conversion of a surface pump or submersible pressure pump into a pump with automatic switching (domestic water pump).

The appliance is suitable only for conveying the following fluids:

Clean water
Rainwater
Chlorinated water (swimming pool water).

Any use not in accordance with this designated use shall be regarded as misuse

Possible misuse

The pump must not be operated continuously. It is not suitable for conveying:

Drinking water
Saltwater
Foodstuffs
Wastewater
aggressive media, chemicals
corrosive, flammable, explosive or fuming fluids
fluids that are hotter than 35 °C
water containing sand and abrasive fluids.

SAFETY INSTRUCTIONS

DANGER! Danger from contact with live parts! A defect in the pump or the extension cable can result in serious injury!

Disconnect the connector plug from the mains immediately.
Connect the device via an earth leakage circuit breaker with a rated leakage current of < 30 mA.
WARNING! Risk of injury. Defective and disabled safety and protective devices can result in serious injury.
Have any defective safety and protective devices repaired.
Never disable safety and protective devices.
CAUTION! Danger of injury from hot water After extended use against the closed pressure side (> 10 min.), the water in the pump canbecome very hot and may escape uncontrolled!
Disconnect the pump from the mains supply and allow the pump and water to cool down.
Check the water level on the suction side.
Check the leak-tightness of the lines.
Check the installation of the suction and pressure lines.
Put the pump into operation again only after all the faults have been remedied!

General safety warnings

This appliance can be used by children of 8 years and older and by persons with reduced physical, sensory or mental capabilities, or those lacking experience and knowledge, if they are supervised or have been instructed with regard to the safe use of the appliance and the ensuing risks. Children must not be allowed to play with the appliance. Cleaning and maintenance must not be carried out by children without supervision.
People with very strong and complex restrictions may have needs that exceed the instructions described here.
Never lift, transport or affix the pump by the mains cable. Do not pull the mains cable in order to pull the mains plug out of the socket.
Unauthorized modifications or conversions to the pump are prohibited. Repairs may only be carried out by our customer service.
Disconnect the mains plug before working on the device. Protect the mains plug against moisture.
Only use the pump and extension cable if they are in flawless technical condition. Damaged appliances must not be operated.
Maintain a safe distance to persons or animals or switch off the pump if animals approach.

Electrical safety

The pump may not be operated while people are in the pool or pond.
The mains voltage at your location must comply with the information regarding mains voltage in the Technical Data. Do not use any other supply voltage.
The appliance must only be operated on electrical equipment in accordance with DIN/ VDE 0100, parts 737, 738 and 702. For fuse protection, a circuit breaker of 10 A and an earth leakage circuit breaker with a rated leakage current of 10/30 mA must be installed.
Use only 3 x 1.5 mm2 extension leads of quality H07RN-F to DIN 57282/57245 with splash-proof plug connector. Cable drums must be completely unwound.
The power consumption of the connected pump must not exceed 10 A, and its operating pressure must not be less than 1.8 bar or more than 8 bar.
Always switch off the pump operated with the pressure switch and pull the mains plug of the connecting lead out of the plug socket before starting maintenance, service and repair work or in the event of faults. Protect the mains plug from moisture

INSTALLATION

IMPORTANT! Danger of damage to the pump! If a pre-filter is not installed, solids can enter the pump and cause damage.
■ Install a pre-filter in the suction line for safe operation of the pressure switch.

NOTE The pressure switch can be installed at any point in the pressure line. The pressure switch must always be installed vertically. If direct installation at the pump outlet is not possible for space reasons, a suitable connector must be used.

Install the pressure switch (1″ male thread) to the pressure line connection at the pump outlet.

START-UP

NOTE The pump cannot be filled via the pressure switch, as a check valve is installed in front of the pump.
NOTE During commissioning, the pump switches off automatically after approx. 10 s. The “RESET“ (8) button must then be pressed until the pump starts to deliver water. If the “RESET” button is released before the pump starts to deliver water, the pump switches off again automatically for safety reasons. Should the priming process take longer than 2 minutes, fill the pump and suction hose again, check the screw fittings for leaks and repeat the process.

Fill pump and suction until they overflow.
Open a shut-off device (valve, spray nozzle, water cock) in the pressure line.
Insert the plug of the mains cable into the power socket. The pumps starts to operate.
Close the shut-off device in the pressure line when water flows out of the line without bubbles. The pressure switch switches off the pump automatically after approx. 15 s. The appliance is ready for operation.

OPERATION

Commission the appliance as described. The pressure switch is electronically controlled and operates fully automatically after commissioning.

Manual restart

After malfunctions or if no water is pumped during commissioning, the pump has to be started manually.
Check the suction side of the appliance and the water level.
Start the pump by pressing the “RESET“ (8)button.
If no water is pumped after several unsuccessful attempts, check the screw fittings for tightness and fill the pump again.

Switching the pump off

Remove the mains plug from the plug socket.

Operating status displays

The operating statuses are signaled by means of indicator lights (LED). “Power” indicator light (5) Indicates whether the appliance is connected to the mains power supply. “Failure” indicator light (6) Indicates that a malfunction has occurred. “On” indicator light (7) Indicates that the pump is in operation.
