BRITTHERM 25-6-130 P1 Circulator Pump
WARNING SIGNS
PLEASE READ DETAILED INSTRUCTIONS
Only qualified and licensed engineers should install the pump. If you do not
have an engineer to install and operate the pump, we strongly recommend
contacting the local engineer or visit us at
www.brittherm.co.uk
or call us on 0208 9044 832. You should carefully read the instructions and
specifications of the pump, purpose and recommendations for pump operation
before changing the pump operation mode (speed). The best way is to contact
the engineer who installed the pump for you and consult with him on the issues
in which you are interested. Once the installation has been completed and the
pump has been commissioned, you have 30 calendar days to register your
warranty at https://www.brittherm.eo.uk/guarantees by scanning the QR code
that you see on the pump nameplate. To complete the warranty registration, you
will need the following information: pump model, invoice number,
purchase/installation date, name and email address of the owner, and address
where the pump is fitted. Please see the last page for the warranty
information.
In case of any anomalies that you observed in the pump operation, you should contact the engineer who installed the pump for you and consult with him. Do not try to disassemble and troubleshoot the pump yourself. This can be a life- threatening activity.
PRODUCT DESCRIPTION
Pl Series Pumps are a new generation of high-efficiency circulator pumps produced according to the technology of compact rotor with permanent magnets that meet the most strict ErP regulations (EEl is ≤ 0.16~0.23). A key feature is the intelligent AUTO mode, which automatically adjusts to the specifications of any heating system to guarantee optimal comfort and minimum energy consumption, i.e. to achieve the best effect for any closed heating system.
It is suitable for:
- Domestic heating systems
- Radiator heating
- Underfloor heating
- Non-potable water recirculation
- Cooling systems
- Air conditioning systems
- Solar heating systems
- Heating systems using heat pumps
The pump design consists of a motor and a pump body. The cast iron volute pump casing (pump volute) has a cataphoretic coating that acts as a protective layer providing ten times greater corrosion resistance than untreated cast iron. The electric glandless pump motor provides lubrication of bearings and cooling by the pumped fluid. An aluminium alloy body reliably protects motor windings. The body is ventilated to prevent condensation and corrosion. Operating modes of the pump are selected with a single button on the body (see Section PROGRAM CONTROL). A flat-head screwdriver plug is provided to unlock the pump rotor after a long period of inactivity, which gives access to the rotor to unlock it by turning with a suitable screwdriver. The pump is simply connected to the electrical network on site using spring-loaded electrical clamps in a terminal box with protection at IP44 level. The pump is mounted using coupling nuts.
PUMP OPERATION
Make sure that the heating system is filled and under the required pressure before turning on the pump. Pump operation without the pumped fluid can disable the pump. Warranties do not cover such breakdown. Make sure that the pump is installed correctly, check the direction of the required fluid flow, check that there are no fluid leaks at the pump and pipe connections. Check the correct connection of the electrical cable – phase, zero and ground. Unscrew the pump plug from the back of the motor to remove air from the pump and unlock the rotor. Water will flow out of the pump – this is normal. Prepare a container to collect water.
- Do not unscrew the plug immediately after pump shutdown – the fluid is hot and can cause burns.
- Wait some time to bleed air from the pump.
- Turn the motor shaft with a suitable screwdriver.
- Screw on the plug. Make sure that the valves upstream and downstream of the pump are open.
- Energise the pump. The pump operation and rotor rotation direction should be checked using special tools – rotation indicators, which the engineer must have. The pump should run quietly.
- Bleed air as described above if extraneous noises appear.
When doing this procedure, be sure to turn off the pump and make sure that no fluid comes into the electrical terminal box. Ideally, the air should leave the heating system through air vents on top of the system.The pump is mounted using coupling nuts.

PACKAGE
- Pump assembly – I piece;
- Set of coupling nuts with gaskets – I set;
- Power cable, 1.3m long, with plug (UK) – I set;
- Installation and operation manual – I piece;
- Individual packaging – I piece.
Full specifications are given in Appendix I thereto.
INSTALLATION
Pump figures are given to understand the installation rules and may differ from the actual products.
Pumps should be installed by personnel who have a permit to work with electrical equipment, trained and have sufficient experience in operating similar pumping equipment! Check for completeness, absence of mechanical damage on the pump, nuts, electric cable and electric plug before installation. The pump motor, during installation, should always be placed parallel to the horizontal surface relative to the floor in the room. In intallation, please pay attention to the flow direction of the heating medium. An arrow on the pump body shows the flow direction forced by the pump. That direction must be compliant with the circulation of the medium in the system.
- In installation, please use the bolts with rubber sealing included in the set.
- The pump should be installed in such a way that the pump shaft is horizontal.
Change in the arrangement of the control panel.
The control panel along with the motor corpus rotate every 90° . To change the position of the junction box, perform the following activities:
- Disconnect the pump from power supply. Close the cut off valves at the inflow and outflow of the pump and perform decompression;
- Loosen and remove four bolts fixing the head in the pump body;
- Rotate the motor into the desired position and fit four opening for bolts;
- Insert four ampoule head screws to proper sockets and tighten them;
- Open the valve
The heating medium can have high temperature and pressure, therefore it is necessary to discharge the liquid from the system or close the cut-off valves on both sides of the pump befor the ampoule head screws are removed. After the position of the pump control panel is changed, do not start it before the heating system is refilled with the heating medium or before the cut-off valves before and after the pump are opened.
Pump body and motor body thermal installation
In oder to limit heat losses at the heating medium flow through the pump and motor body can be thermally insulated by means of, for example, a Styrofoam lining. Do not insulate or cover the junction box or control panel.
The P-Series pump uses a quick-release connector. Just connect the power cable to the connector.
- Brown – to terminal L (phase);
- Blue – to terminal N (neutral); Yellow-green – to terminal@ (ground).
Wire with plug is supplied complete with the product.
Be sure to check the compliance of the mains voltage at the site and on the pump nameplate marking. The use of grounding is a prerequisite for ensuring the electrical safety of the equipment, as well as the safety of people in this room and in rooms nearby.
PUMP MAINTENANCE
The pump structure is designed in such a way that it does not require special maintenance throughout the entire period of its operation. When you first turn on or after a long period of inactivity of the pump, it is necessary to remove air from its body, as well as unlock the pump rotor shaft. To do this, unscrew the plug on the back of the pump, and turn the shaft with a suitable size screwdriver one half turn. At the same time, do not forget to prepare a container to collect a small amount of water that will be under the plug at the moment of its removal. If shut-off valves were used on both sides of the pump when installing the pump, close them before starting to unblock the pump and the amount of coolant that can out from under the plug will not be more than 100-200 ml. It is recommended at least once every 6 months to check for fluid leaks at connections, for damage of the supply cable. The pump should always run with a full system. Bearings are lubricated and pump is cooled by the pumped fluid.

MALFUNCTIONS
The pump is an engineering equipment in which the electrical part (motor)and the pumping part, where the fluid is pumped, are combined. Therefore, when performing any work, it is necessary to follow the electrical safetyrules. Be sure to turn off the power before doing any work. Make sure that fluid does not enter inside the terminal box and electrical cables, plugs, sockets, etc. If you find any malfunctions or failures, we recommend you to contact the engineer who installed the pump first and then Brittherm Limited by 0208 9044 832 or email
