Frequently Asked Questions - Quantum Mini Baxi

How to install the Baxi Quantum Mini pump?

Installation must be carried out by a qualified professional. Disconnect the power supply before any intervention. Mount the pump in a horizontal position (see Fig. 3), with the flow direction corresponding to the arrows. Flush the circuit before installation. Use shut-off valves upstream and downstream.

What regulation modes are available?

The pump offers two modes: variable differential pressure (Δp-v) which adapts the head to the flow, and constant speed with three fixed speeds (I, II, III). Switch between them by briefly pressing the control button.

How to vent the pump?

The rotor chamber vents automatically after a few minutes of operation. If noises persist, perform several start/stop cycles. Short dry running does not damage the pump.

What to do if the pump does not start?

First check the fuse and power supply. Make sure the voltage matches the rating plate. If the problem persists, call a qualified electrician.

How to adjust the characteristic curve?

Briefly press (1 second) the control button to scroll through the modes and curves. The LEDs indicate the selection: for Δp-v mode, curves I, II, III are available; for constant speed, three fixed speeds. The 6th press returns to the initial setting.

What is the maximum operating pressure?

The maximum operating pressure is 6 bar (600 kPa). Do not exceed this value to avoid damage.

Can the pump be thermally insulated?

Only the pump body can be insulated. The motor, regulator module, and condensate discharge openings must remain clear to avoid overheating.

How to maintain the pump?

Before any maintenance, disconnect the power supply and let the pump cool down. Clean the outside with a damp cloth. Never remove the motor cover. In case of leakage, replace the gaskets with original parts.

Is the pump suitable for children?

The appliance can be used by children over 8 years of age under supervision. Children must not play with the pump. Cleaning and user maintenance must not be performed by children without supervision.

What to do in case of abnormal noise?

Noise may indicate cavitation due to insufficient inlet pressure. Increase the inlet pressure within the permissible limits or reduce the set head. If the noise persists, check that the pump is properly vented.

3 Description and function

3.1 Intended use

The circulators in this series are designed for warm water heating systems and similar systems with constantly changing flows.

The approved fluids are heating water in accordance with VDI 2035, and water/glycol mixture at a mixing ratio of 1:1.

If glycol is added, the delivery data of the pump must be corrected according to the higher viscosity depending on the mixing ratio.

Intended use includes the observation of these instructions as well as of specifications and labelling on the pump.

Any other use is regarded as improper use.

3.2 Product description

The pump (Fig. 1/1) consists of a hydraulic system, a glandless motor with a permanent magnet rotor, and an electronic control module with integrated frequency converter.

The control module contains an operating button and LEDs (Fig. 1/2) for setting and displaying all parameters.

4 Installation and electrical connection

4.1 Installation

DANGER: Before starting work, make sure that the pump is disconnected from the power supply.

Installation site

- Provide a weatherproof, frost-free, dust-free, and well-ventilated room for the installation.

Choose an easily accessible installation site.

- Prepare the installation site so that the pump can be installed without being subjected to mechanical stresses. If necessary, support or secure piping on both sides of the pump.

NOTICE: Provide shut-off devices upstream and downstream of the pump to facilitate potential future pump replacement. Perform the installation in a way that prevents leaking water from dripping onto the control module. To do this, align the upper gate valve laterally if necessary.

- Complete all welding and soldering work near the pump prior to the installation of the pump.

CAUTION: Dirt can cause the pump to fail. Flush the pipe system before installation.

- Choose the correct installation position, with the pump motor in a horizontal position, from only the positions shown in (Fig. 3). Direction arrows on the pump housing indicate the direction of flow.

- If heat insulation work is necessary, only the pump housing may be insulated. The pump motor, module, and condensate drainage openings must remain uncovered.

Turning the motor head

If the installation position of the module is changed, the motor housing must be turned as follows:

• If necessary, remove the thermal insulation shell.
• Loosen the interior hexagonal head screws.
• Turn the motor housing, including the control module.

NOTICE: In general, turn the motor head before the system is filled. When turning the motor head in a system that has already been filled, do not pull the motor head out of the pump housing. Turn the motor head with a small amount of pressure on the motor unit so that no water can come out of the pump.

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

- Turn the motor head in such a way that the plug corresponds to the permitted installation position (Fig. 3).

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

• Turn in the interior hexagonal head screws.
• If applicable, re-mount the thermal insulation shell.

4.2 Electrical connection

DANGER: Work on the electrical connection must be performed only by a qualified electrician and in accordance with national and local regulations. Before making the connection, ensure that the connecting cable is not live.

• The mains voltage and current type must correspond to the rating plate specifications.

• Connect the plug (Fig. 4a to 4e).

• Mains connection: L, N, PE.

• Max. back-up fuse: 10 A, slow-blow.
• Earth the pump in accordance with instructions.
  Dismantle the plug in accordance with Fig. 5. A screwdriver is required to do this.

- The electrical connection is to be established via a fixed connecting cable equipped with a connector device or an all-pole switch with a contact opening width of at least 3 mm.

- To ensure drip protection and strain relief at the PG screwed connection, a connecting cable with an adequate outer diameter is required (e.g. H05VV-F3G1.5).

- For pumps in systems with water temperatures above 90 °C, install a suitably heat-resistant connecting cable.

- The connecting cable is to be laid in such a way that it can under no circumstances come into contact with the pipe and/or the pump and motor housing.

- The switching of the pump using triacs / solid-state relays must be tested on a case-by-case basis.

CAUTION: Voltage pulsing during phase angle control or external control can cause damage to electronic components.

- Only operate the pump with sinusoidal AC voltage as stated on the rating plate.

- The switching of the pump using triacs / solid-state relays must be tested on a case-by-case basis.

5 Commissioning/operation

WARNING: Depending on the pump or the system operating conditions (fluid temperature), the entire pump can become very hot. There is a risk of burns upon coming into contact with the pump! Commissioning by qualified personnel only!

5.1 Venting

• Fill and vent the system appropriately.
• The pump rotor space vents automatically after a short time in operation. This may cause noises. If necessary, switch off and on again repeatedly to speed up the venting process. The pump will not be harmed by dry running for short periods.

5.2 Setting the control mode

Selecting the control mode

The control modes and corresponding characteristic curves are shown on the LED display in clockwise succession.

6. Constant speed		III

After pressing the button 6 times, the selection will have returned to the basic setting (constant speed / characteristic curve III).

NOTICE: All settings and displays are retained if the mains supply is interrupted.

6 Maintenance/faults

DANGER: Before starting any maintenance and repair work, disconnect the pump from the power supply and make sure it cannot be switched back on by unauthorised persons.

• Damage to the connection cable must always be repaired by a qualified electrician.
• Faults must only be remedied by qualified personnel!

WARNING: Risk of burns when touching the pump!

Depending on the pump or the system operating conditions (fluid temperature), the entire pump can become very hot.

When removing the motor head or pump, hot fluid may be expelled under high pressure.

- Allow the pump to cool down first.

- Close the stop valves before removing the pump. There is always a strong magnetic field inside the motor. The permanent magnet rotor installed in the pump can pose mortal danger to people with medical implants (e.g. pacemakers) during dismantling.

- Never open the motor and never remove the rotor.

Fault Cause Remedy
Pump is not running although the power supply is switched on	Electrical fuse defective	Check fuses
	No voltage supply to the pump	Resolve the interruption to the power supply
Pump is noisy Cavitation due to insufficient suction pressure		Increase the system supply pressure within the permissible range
		Check the delivery head setting and set it to a lower height if necessary
Building does not warm up	Thermal output of the heating surfaces is too low	Increase setpoint
