3 Port Motorised Valve Actuator
Important: Keep this document
The B1PF range of actuators c/w auxiliary switch are specically
designed for use in domestic applications only.
They are not designed for use in commercial or industrial
applications such as schools, nursing homes or hotels where large
commercial pump sets are tted.
Warranty will be void If a valve is tted in any application other
than domestic.
Please note we have a full range of commercial and industrial valves
to suit every application.
CAUTION! Installation and connection
should only be carried out by a qualied person
and in accordance with wiring regulations.
Do not open the products. There are no serviceable
or adjustable parts inside. The system must be fused
to no more than 3 Amps.
Isolate mains supply before installation commences.
Isolate mains supply before attaching cable to
actuator.
Isolate mains supply before detaching cable from
actuator.
If this equipment is installed or used in a way not
specied by the manufacturer, its safety may be
impaired.

INSTALLATION & OPERATING INSTRUCTIONS
CAUTION!
Ensure that no more than a 3A fuse is used to supply all controls.
It is not permissible to use any voltage other than 230V on the auxiliary switch.
Electrical installation must conform with current I.E.E. regulations.
1. Valve positioning
Install the valve so the actuator head is not below the horizontal level of the pipework. The open vent and
cold feed must not be isolated. The ow must be in the direction of the arrow. (from the centre port to either
Port A or Port B).
2. Fitting the valve body to the pipework
Fit the valve body using the nuts and olives provided. When tightening the compression nuts ensure that
only the valve body is used for grip. Take care not to overtighten.
3. Removal of actuator from the valve body
To remove the actuator head from the valve body ensure that the manual override lever is in the manual
position. Remove the two screws that x the actuator cover to the base. Remove the actuator cover. Remove
the two screws that x the base to the valve body. Remove the base of the actuator.
4. Fitting of actuator to the valve body
Before tting the actuator, please ensure that the maual override lever is in the raised manual position and
the xing screw is loosened. The actuator is mounted by aligning the 4mm at spindle on the valve body to
the identically sized slot on the actuator. Tighten the two xing screws on the base of the actuator. Fit the
actuator cover and tighten the two screws to hold the cover in place.
Once the valve is tted, place the manual override lever in the raised manual position. It is now possible
to ush and drain the system to remove any foreign matter. The system can now be relled and corrosion
inhibitor may be added if required.
5. Wiring Connections
5.1 The 1.2 metre cable can be connectd as follows:
WIRE COLOUR DESCRIPTION
Blue Neutral supply
Orange Hot Water ON from cylinder stat or ON from programmer
Also connect to boiler and pump live.
Grey Hot Water OFF from cylinder stat or OFF from programmer
White Central Heating ON from room stat or ON from programmer
Yellow / Green Earth connection
Page 3
WARNING!
Under no circumstances should the actuator be insulated or covered by any other material.
Lack of ventilation will cause the actuator to heat up beyond the maximum permissible ambient temperature
of 50˚C.
WIRE COLOUR DESCRIPTION
Blue Neutral supply
Orange Hot Water ON from cylinder stat or ON from programmer
Also connect to boiler and pump live.
Grey Hot Water OFF from cylinder stat or OFF from programmer
White Central Heating ON from room stat or ON from programmer
Yellow / Green Earth connection
6. Commissioning
Once the system has been lled and vented, ensure the manual override lever is in the auto position.
7. For Hot Water only
Switch the Central Heating ‘OFF”at the programmer or set the room thermostat to the minimum. Switch the
Hot Water “ON”at the programmer and set the cylinder thermostat to the maximum. Port “B” should open on
the valve. The boiler should re and the pump should run. The pipe connected to Port “B” should get hot.
8. For Central Heating only
Switch the Hot Water“OFF” at the programmer or set the cylinder thermostat to the minimum. Switch the
Central Heating “ON” at the programmer and set the room thermostat to the maximum. Port “A”should open
on the valve. The boiler should re and the pump should run. The pipe connected to Port “A” should get hot.
9. For Hot Water and Central Heating
Switch both the Hot Water and the Central Heating “ON” at the programmer. Set both the room thermostat
and the cylinder thermostat to the maximum. The valve should go to the mid position with both Port “A”and
Port “B” open. The boiler should re and the pump should run. The pipes connected to Port “A” and Port “B”
should get hot.
Once satised with the valve operation, reset the programmer and the thermostats to normal control
settings.
5.2 For use as a Diverting Valve, see table below:
ELECTRICAL CONNECTION CABLE CONNECTION VALVE POSITION
Not connected Not connected Hot Water “Port B” open.
230V connected to Orange core Hot Water “Port B” open.
230V connected to Grey core Hot Water “Port B” open.
230V connected to White core Mid position “Port A” and “Port B” open.
230V connected to Grey & White cores Central Heating “Port A” open.

WARNING!
Under no circumstances should the actuator be insulated or covered by any other material.
Lack of ventilation will cause the actuator to heat up beyond the maximum permissible ambient temperature of 50˚C.
