USER INSTRUCTIONS
Operating Description
The influence of uncontrolled heat gains horn cooking, lighting, sunshine,
etc., can lead to wasteful overheating. The terrier TRV is designed to react
to temperature fluctuations and allow you to control individual room
temperatures. The sensor head contains o powerful wax-filled sensor which
senses temperature changes. These variations cause expansion and contraction
of the thermal element which is transmitted lo a valve seat that regulates the
water flow to the radiator.
Setting the TRV
Initially set the TRV lo the required room temperature from the table below
e.g. Position 3/ 20°(. The TRV should be left for al least l hour to allow the
temperature to stabilize. If o higher or lower room temperature is required
simply adjust the setting accordingly and repeal the process.
Temperature Settings
The TRV settings are factory calibrated as indicated in the table below.
Note These temperatures may vary slightly, depending upon the nature of the installation.
Range Limiting or Fixed Set Temperature
The terrier TRV has the facility for fixing the thermal head at o set temperature or limiting the range of operation. This is achieved by using two pegs; o order these pegs FOC please contact our sales office and quote (850888). To obtain o fixed set point, locate a peg in the slot on either side of the selected setting and push home. To set o limited range for temperature control, first, locate a peg in the slot to the right of the viewing window for the lowest temperature setting required. Adjust the valve head to display the maximum temperature desired. locate o peg in the slot to the left side of the viewing window. Push both pegs home. The head will now be adjustable between the selected range of temperatures.
Frost Protection
If you pion to be away from home for any length of time the TRV can be turned
to the frost protection setting “*”. If the temperature falls below 7°C the
valve will automatically open giving protection against freezing. (Provided
that the boiler remains in operation via a frost slot.)
Removal of Radiator
The “O” Setting on the TRV is o positive “Off” position. This will enable o
radiator to be removed for maintenance purposes. To avoid occidental operating
of the valve or damage whilst decorating the manual shut-off cop may be used
for added security instead of the TRV head. In this case, remove the TRV
sensor head by unscrewing the securing ring and replacing it with the manual
cop BEFORE removing the radiator.

INSTALLATION
Direction for use
Angle TRV
The universe terrier TRV is designed to operate with water flow in either
direction.
Angle MRV
The push-fit manual range consists of a Manual wheel head, lockshield, and
Drain lockshield valves.
Correct installations
Correct installation and maximum performance will only be achieved if the
thermostatic head is not concealed behind furniture, curtains, or drapes,
hidden under shelves, paneling, or in a recess where air pockets can occur.
The thermostatic head should not be exposed to direct sunlight or droughts.
Fitting the Valve Connections
- Thoroughly clean pipework to be connected to the valve.
- Drain down the existing system, connecting o hosepipe to the lowest drain-off point available.
- Screw ½” BSP toil into radiator tapping, using suitable jointing material e. g. PTFE lope.
- Connect the valve body lo toil and tighten the nut.
Fitting the Elbows
- Ensure the elbows toil is fully inserted into the valve and secured on the toil groove.
Fitting with Copper Pipe ((upper or(home)
- Using the deburring and scribing combination tool (soles code 7Pl0l 5), insert the pipe into the correct size and debut pipe, mark insertion depth or measure accurately with a ruler. (3o & 3b) (Important note: ensure the lube is cut square and all burrs and sharp edges are removed ta prevent ‘O’ ring damage and seal failure).
- If the chrome-plated pipe is used fully insert the pipe into a combination tool in the correcl size and press button while relating the pipe several times to score the tube. (l)
- Inspect the fitting ensuring 1h01 the grab ring and ‘O’ ring has not been contaminated with grit and debris, insert pipe info and push fit end by rotating the pipe until insertion depth is reached.
Fitting the Plastic Pipe
- Cut the pipe with approved pipe shears.
- Insert pipe support liner.
- With the support liner in place, mark the insertion depth either with a scribe tool or measure accurately with a ruler. (See table 3b)
- Inspect the fitting ensuring that the grab ring and ‘O’ ring have not been contaminated with grit and debris, insert the pipe into the push-fit end by rotating the pipe until insertion depth is reached.
Demounting
- Clip release tool with the recess side towards the body.
- Press the tool firmly ta the underside of the body and withdraw the pipe at the same
Fixing the Thermostatic Head
- Remove manual shul off cop ond store safely.
- Turn the Sensor head to indicate “5” in the setting window.
- Position the sensor head so that the setting window can be viewed and hand-tighten securing ring to the valve body.
- Set the sensor head to the required temperature setting.
- When fitting a lock shield valve, this must be set to control the water flow through the radiator ta the correct level.
PLEASE NOTE
To avoid the problem of hydronic (water flow) noise it is recommended that the
differential pressure does not exceed 0.2 bar. It is strongly recommended that
a differential pressure valve should be fitted to one system with TRV (Pegler
order code for differential pressure valve 678021122mm) will be suitable for
most domestic installations. larger sizes are available if required.
