Installation Guide
1. Ensure the pipe is pushed
to the pipe stop in the
elbow.
1. Remove cap from valve and turn sensor to
2. Make sure union nut is
turned loosely up towards
the sensor body until it
is only slightly free of the
lower part of the sensor
body.
2. IMPORTANT: Both nuts
have to be tightened It
is good practice to check
the fitting before use: pull
the pipe back to check it is
secure.
3. Press the sensor firmly
onto the valve.
Sensor horizontal:
ensuring that the scale
pointer is at top.
Dismounting
IMPORTANT: Ensure
system is depressurised
before removing fitting.
Sensor vertical: ensuring
that the scale pointer is
at the front.
Push in collet squarely
against face of fitting.
With the collet held in this
position, the pipe can be
pulled out. The fitting can
then be re-used.
4. Whilst holding the
sensor firmly on the
valve secure connection
by turning union nut
clock-wise by hand.
5. Whilst still holding the
sensor firmly on the
Collet cover and collet clip
valve, tighten the grey

parrot nose pliers.
Collet covers or collet clips provide added security against
unintended pipe disconnection.

Code No 013G4913 (10 pcs)
Code No 013G4912 (10 pcs)
Turn the sensor to max. position Turn union nut anti-
clockwise to release lockingmechanism (4). The sensor can
now be separated from the valve.
Cutting the pipes
1. Cut the pipe square ensuring that it is free from score
marks and burs. For plastic pipe we recommend the use
of a plastic pipe cutter, do not use a hacksaw

Setting the desired room temperatures
2. For plastic pipes, it is essential that a pipe insert is used.
This must be of the same make as the pipe. It is important
to ensure that all internal burs are removed from the pipe
end prior to fitting the insert. Do not use any lubricant.
The desired room temperature is set by turning the head. The
temperatures obtained are approximately:
Specification
Copper pipe
According to BS2871 Part 1 / BS EN1057. Max. temp.
92°C, Max. pressure 3 bar
Plastic pipes:
According to BS7291. Max. temp. 92°C. Max.
pressure 3bar
Do not cover the thermostat
The thermostat opens and closes as determined by the
temperature around it. Therefore the sensor must never be
hidden behind thick curtains, furniture, etc. Alternatively a
thermostat with remote sensor should be used.
Positive SHUT-OFF feature:
The head can be turned past the setting (a slight
resistance will be felt) to setting "0" at which point the
water flow is shut off completely. After also shutting the
lockshield valve the radiator may be drained and removed
for maintenance and decoration purposes.
