The F228m / F228e valve with auxiliary switch has been designed
to control the water circulation in fully pumped systems, which
employs a single pump for both Hot water and Central heating
circuits, by allowing the flow to either or both circuits using
separate valves.

INSTALLATION AND CONNECTION SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED
PERSON AND IN ACCORDANCE WITH THE CURRENT EDITION OF THE I.E.E. WIRING
REGULATIONS. A CLASS ‘A’ SWITCH (HAVING CONTACT SEPARATION OF AT LEAST 3MM IN
ALL POLES) MUST BE INCORPORATED IN THE FIXED WIRING AS A MEANS OF DISCONNECTING
THE SUPPLY, NORMALLY AT THE CONSUMER UNIT. THE SYSTEM MUST BE APPROPRIATELY
FUSED.

COMMISSIONING
To check whether the valve is operating correctly, carry out the following checks after the system is filled and vented. Ensure that the override lever is in the Auto position and the insert
guide is removed.

open. The boiler should fire, the pump run and the pipe on the Port B side should get hot.
Reset both thermostats and the programmer to their normal settings.
PPlleeaassee nnoottee
the above assumes that both programmer and thermostats are being used. If this
is not the case, ignore the action described for the item not fitted.
Fit the valve body using the compression fittings provided.
Tighten the compression nuts sufficiently to make a watertight seal, only gripping the valve
by its body.

INSTALLATION AND OPERATING INSTRUCTIONS
POSITIONING OF VALVE
On new installations fit the valve ensuring that the actuator head is NOT below the
horizontal level of the pipework and that flow is in the direction of the arrow. Also check that
neither the open vent or the cold feed are isolated. This will ensure system and product
safety at all times.
Remember to make allowances for working, maintenance and replacement.

Position the actuator on the valve body, taking care to line up the 4
mm flat spindle, located
on the valve body, with the receiving shaped slot located on the underneath of the actuator.
The actuator guide holes should line up with the spigot on the valve body.
The actuator locking mechanism will click into place, locking the head to the valve body.
WIRING CONNECTIONS
The 6 core cable fitted to the actuator can now be connected to the system following the
simple colour-coded guide below.
An earth connection is required on the F228m and F228e valve. Ensure all connections are
good and the screw secure. A torque of 0.75Nm is recommended for fixing the wires in place.
NNOOTTEE::
In the event that the F228m or F228e is being used in an unconventional system, the
above connections may be incorrect. In this case, please seek advice.

Valve position - In the event that mains power is disconnected the valve automatically
spring-returns to the closed position (Port A).

OPERATION
Set the override lever to manual. Fill, test and thoroughly flush the system (See instruction
under the Specification section located on page 4 of this guide).
To remove the Actuator from the valve body please ensure that the override lever is placed
in the override position.
