2.1. Check list
• Check all connections for securing and leaks.
• Use clean pipework, free from swarf.
• Consider the use of an automatic by-pass valve
(e.g. Honeywell DU145) to ensure the specification is adherded to.
• Don’t allow heat from blow torch onto body.
• Don’t install the valve in a position which is subject to draughts, sun
radiation or behind curtains.
• Don’t overtighten the head/body connection, as the insulating sleeve
may become damaged.
3. Location
The thermostat can be fitted in any orientation with the flow through the
body in either direction.
4. Technical Data
Maximum working pressure 10 bar (140 psi)
Closing time 20 minutes
To ensure that the valve will thermostatically close the differential pres-
sure must not exceed 1.0 bar.
Maximum differential pressure to ensure reliable and quiet operation is
0.2 bar.

What is a thermostatic radiator valve (TRV)?
..an explanation for householders
TRVs sense the air temperature around them and
regulate the flow of water through the radiator which they are fitted
to. They do not control the boiler.
TRVs sense the air temperature around them and regulate the flow
of water through the radiator which they are fitted to. They do not
control the boiler.
They should be set at a level that gives you the room temperature
you want. These settings may have to be different in each room,
and should set the TRVs to suit each room an then leave them to
do their job.
Turning a TRV to a higher setting will not make the room heat up
any faster. How quickly the room heats up depends on the boiler
size and setting, and the radiator size. Turning the TRV to a lower
setting will result in the room beiing controlled at a lower tempera-
ture, and saves energy.
TRVs need a free flow of air to sense the temperature, sp they must
not be covered by curtains or blocked by furniture.
TRVs cannot turn off the boiler when the whole house is warm. To
do that, you will need a room thermostat as well. The radiator in the
room with the romm thermostat should normally have a TRV, but, if
it does, keep the TRV on the maximum setting and adjust the room
thermostat as explained with the instructions.

6.3. Lockshield valve
1. Install the lockshield valve opposite from thermostat
7. Adjustment / Setting of thermostat
The VTL120 is adjustable by turning the top anti-clockwise to increase
temerature setting or clockwise to decrease temerature setting.
These temperatures are for guideance only and are based on vertical
mounting on the flow pipe. If the radiator thermostat is installed in any
other direction then the temperature will vary by 1°C to 2°C.
NOTE: Heating can freeze when thermostats with zero position are
set at position „0“.
8. To shut off the lockshield valve
1. Unscrew and remove
cover cap.
2. Turn the spindle clockwise
till stop by using a pliers
3. Fit cover cap.
9. Service
9.1. Decorator cap
When removing the radiator
for any reason the decorators
cap supplied with the valve should be used to isolate the flow.
9.2. Servicing
Use the service tool WV108M for cle-
aning or replacement of the valve
seating without draining the system.
For further informations see seperate
manual.
