MYSON POWER EXTRA
SPRING RETURN ZONE VALVE
MPE 222 / MPE 2 3/4 “- 2 PORT 22mm VALVE
Thank you for choosing a MYSON heating control.
The MPE 222 is designed to control water circulation in primary hot water
or central heating circuits. The motor is powered to open the valve with a
spring return to the closed position.
The valve is not directionally sensitive and may be fitted with flow through
either Port A or Port B.
For convenience the neon indicator light illuminates, indicating when the
valve is open.
When the manual lever is moved to the right, the valve is open. This is used
when filling, venting or draining the system. The spring return valve rests
in the closed position.

INSTALLATION INSTRUCTIONS
Step 1. Select Valve Position:
Choose a suitable position for the valve in
the circuit to be controlled, which allows
sufficient access for wiring and
maintenance.
The position chosen must not isolate the
boiler from the open vent or the cold feed
pipe work.
The valve may be fitted in a horizontal,
vertical or inclined orientation and may be
fitted on either the flow or return circuit.
The actuator must not be fitted below the
valve body.
Step 2. Fit Valve Body to Pipe work:

Fit the valve body using the 22mm
compression nuts provided. Ensure
that the valve body is only gripped
on the hexagonal faces at the valve
ports. Take care not to over
tighten.
Step 3. Fit Actuator to Valve Body:
Position the actuator on the valve body by
locating the spindle in the cam slot.
Rotate actuator until the locating lug (shown)
lines up with locating lug-hole on the mounting
plate (shown).

Fix the actuator to the body by lightly
tightening the screws
Set the override lever to MAN. Fill, test and
thoroughly flush the system.

Step 4. Electrical Connections:
The actuator is fitted with 1100mm of 4-core cable for connection of the system
equipment. The installation will be simplified by the use of an electrical junction
box into which all the system equipment can connect.
The actual wiring connections will depend on the system equipment used,
following the wiring principle outlined below. The MPE 222 is double insulated
and requires no earth connection.

When the installation is complete, filled and vented, check that the valve operates
correctly. Switch on the system controls, i.e. programmer and thermostats: The
valve should move to the open position. When fu
to the valve’s auxiliary switch should operate.
Switch off the heating controls: The valve should spri

When the valve is fitted in confined space, ample ventilation must be
provided to ensure
temperature range.
