3.1 Install the Valve
CAUTION
Some commercial fittings are not tapped deep enough and may
damage the temperature cup. It is recommended that a 22/32 in
diameter tap drill is run through the pipe fitting before installing the
Valve.
To prevent the pushrod being jammed by foreign objects and to keep
the ports clear, the control medium must be filtered before it enters
the Valve.
If the valve is located in a hazardous area and the mounting thread
does not provide good electrical contact between the valve and the
rest of the system, additional earth bonding will be required.
To ensure that the pressure drop is felt at the engine control device.
• An orifice must be fitted in the control medium input line. Suitable
orifices for a wide range of control media are available from
AMOT.
• Pipe lengths must be kept as short as possible to minimise the
control medium volume.
1 Install the Valve into the pipe fitting or thermowell using a quality thread
sealant such as Loctite ™ Pipe Sealant to the pipe thread connections.
If required, two types of stainless steel well can be used. Refer to the
Technical Data, Section 6, page 19 for pressure limits.

Note
When a Valve is ordered in a thermowell, it is assembled by AMOT using
heat transfer compound (Part number 907L002) to minimise the lag time for
changing temperatures.
