Qualification The pump may only be installed by qualified personnel. This product may not be commissioned or operated by per- sons with insufficient accountability (including children) or who do not possess the relevant specialist knowledge. Exceptions are only permitted on appropriate instruction from safety-responsible persons. The electrical connection may only be established by a qualified electrician.

Regulations The current versions of the following regulations must be observed when installing the equipment:

Accident prevention regulations

Other local regulations

Conversion, spare parts The pump must not be technically modified or converted. It is not permitted to open the pump motor by removing the plastic lid. Only use original spare parts.

Transport Unpack and check the pump and all accessories upon receipt. Report any damage sustained in transit immedi- ately. Dispatch the pump in the original packing only.

Electrical current There is a danger of an electric shock when working with electrical current. Therefore:

Switch off the power before beginning work on the pump and make sure that it cannot be switched on again acciden- tally. Do not kink or nip the power cable or allow it to come into contact with heat sources.

The pump is protected against drips in accordance with protection class IP 42. Protect the pump against water spray. Do not immerse in water or other fluids

Installation and operating instructions

3 Principle of operation

Application This circulator is suitable for drinking water only.

The SB-4X is equipped with a non-return valve (1) on the pressure side and with a stop valve (2) on the suction side. When exchanging the motor head (3), it is sufficient to cut the power by unplugging the connector (5) and to close the stop valve at the rotating slot (4). The motor head can then be simply unscrewed → Page 16.

4 Installation and electrical connection 4.1 Mechanical Installation DANGER: Before starting work, make sure that the pump has been disconnected from the power supply. Installation site (Fig. 3) Provide a weatherproof, frost-free, dust-free and well-venti- lated room for the installation. Choose an installation site that is easily accessible. CAUTION: Dirt can cause the pump to fail. Flush the pipe system before installation. NOTE: The stop valve and non-return valve are pre- installed. 1. Prepare the installation site so that the pump can be installed without being exposed to mechanical stresses.

Choose the right installation position - only as shown in (Fig. 3 A). The arrow on the back of the housing indi- cates the direction of flow. Turn the motor head or remove it (Fig. 4)

Release the union nut - unscrew it completely if neces- sary. CAUTION: Do not damage the housing seal. Replace damaged seals.

Turn the motor head so that the connector points down- wards. CAUTION: If the position is wrong, water can penetrate and destroy the pump.

Tighten the union nut again. Open the stop valve (Fig. 5)

Turn slot (1) with a screwdriver so that it is parallel to the direction of flow. NOTE: To close, turn the slot so that it is across the direc- tion of flow.

Fit the thermal insulation shell. CAUTION: The plastic parts of the motor may not be heat- insulated in order to protect the pump from overheating. Connecting (Fig. 6)

Connect the pipework.

CAUTION: For the versions with stop and non-return valves, these are already pre-installed and sealed with a tightening torque of 15 Nm (hand-tight). Screwing with excessive tightening torque destroys the valve screw con- nection and the O ring. When installing the valve, use a fixed spanner to prevent twisting.

Electrical connection

DANGER: Only a qualified electrician is allowed to work on

the electrical connection. Before establishing the connec- tion, make sure that the connecting cable is dead. Establish the electrical connection as follows: (Fig. 7a - Fig. 7e) Open the connector as follows: (Fig. 8)

The pump rotor space vents automatically after a short time in operation. This may cause noises. If necessary, switch off and on repeatedly to accelerate the bleeding. Dry running for short periods will not harm the pump.

17English 5 Maintenance/faults Cleaning Clean the outside of the pump with a slightly damp cloth only. Do not use detergents. Replacing the motor head

WARNING: When removing the motor head or pump, hot

fluid may spurt out under high pressure. Allow the pump to cool down beforehand. Close the stop valves before removing the pump

• Page 16. NOTE: When the motor is removed and running, noises and a change in rotation may occur. This is normal for this situation. Faultless operation can only be guaranteed when the pump is operated in fluid. Replacing the motor head → Page 16. Order the service motor from a specialist retailer.

Faults Causes Remedies Pump does not start. Interruption in the power supply, short- circuit or defective fuses. Have the power supply checked by a qualified electrician. Motor is blocked, e.g. by deposits from the water mains. Have the pump removed by a qualified technician → Page 16. Check that the impeller can move by turning it and rinse out the dirt that has accumulated. Pump is mak- ing noises. Motor scraping, e.g. through deposits from the water mains. Running dry, too little water. Check the check valves, they must be fully open. Air in the pump. Switch the pump on/off 5 times for 30 s in each case.

NOTE: If you cannot remedy the fault, contact a specialist retailer. 6 Disposal Damage to the environment and risks to personal health are avoided by the proper disposal and appropriate recy- cling of this product.
