Frequently Asked Questions - SB10 YA Baxi

How to install the Baxi SB10 YA pump?

Installation must be carried out by qualified personnel. Before any work, cut off the power supply. Flush the hydraulic circuit, mount the pump without mechanical stress, respect the flow direction indicated by the arrow. Open the shut-off valve and bleed the air after filling.

What type of fluid can circulate in the SB10 YA pump?

This pump is designed only for potable water (domestic hot water). Do not use it for other liquids.

What to do if the pump does not start?

Check the power supply: fuses, circuit breaker. If the motor is blocked by deposits, have the pump disassembled by a professional to clean the impeller.

How to clean the SB10 YA pump?

Clean the exterior with a slightly damp cloth without cleaning product. Do not immerse the pump in water.

Can I use the pump for something other than water?

No, the pump is intended exclusively for potable water. Any other use may damage the device and void the warranty.

How to replace the motor head?

Close the shut-off valves, let the pump cool down, disconnect the connector, unscrew the motor head and replace it with an original head. Call a specialized technician if necessary.

What is the maximum operating pressure?

The maximum authorized operating pressure is 10 bar.

How to bleed the pump after installation?

The rotor chamber bleeds automatically after a few minutes of operation. To speed up, turn the pump on and off 5 times for 30 seconds each.

What to do in case of abnormal noises?

Noises can come from deposits in the motor, lack of water, or air in the pump. Check that the valves are open, bleed the air, or have the impeller cleaned by a professional.

Where to find spare parts for the SB10 YA?

Use exclusively Baxi original parts. Contact your installer or Baxi after-sales service to order the motor head or other accessories.

3 Principle of operation

3.1 Application

This circulator is suitable for drinking water only.

3.2 Functions (Fig. 2)

Valves

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-ventilated 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 preinstalled.

1. Prepare the installation site so that the pump can be installed without being exposed to mechanical stresses.

2. Choose the right installation position - only as shown in (Fig. 3 A). The arrow on the back of the housing indicates the direction of flow.

Turn the motor head or remove it (Fig. 4)

1. Release the union nut - unscrew it completely if necessary.

CAUTION: Do not damage the housing seal. Replace damaged seals.

1. Turn the motor head so that the connector points downwards.

CAUTION: If the position is wrong, water can penetrate and destroy the pump.

1. Tighten the union nut again.

Open the stop valve (Fig. 5)

1. 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 direction of flow.

1. 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)

1. 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 connection and the O ring. When installing the valve, use a fixed spanner to prevent twisting.

4.2 Electrical connection

DANGER: Only a qualified electrician is allowed to work on the electrical connection. Before establishing the connection, 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)

4.3 Filling and venting

1. Fill the system
2. 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.

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 making 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.
