2.13 Extra long pockets
Where extra long pockets are used the plain
bulb should be used and inserted the full length
of the pocket.
A split bung is provided to seal the top of the
pocket Fig. 6.
2.14 Heat conduction
Where a bulb is used in a pocket the pocket
should be filled with a heat conducting fluid,
such as thin oil or water, to improve heat
transfer.
Do not fill the extended pocket Fig. 6, above
the level of the bulb.
2.15 Wall mounting sensor
Where the type 37D control is to be used to control from room
temperature the plain bulb Fig. 3 is used and a bracket and
protective shield is provided Fig. 7.
It is essential that the sensor be fitted in such a position that
it can sense the true room temperature and is not influenced
by draughts.
It is preferably fitted in the vertical position and can be fitted
either with the capillary leading from top of the sensor or
leading from the bottom.
Having decided on the sensor position fix the bracket to the
wall making sure that it is fitted in such a way that the lug
standing proud of the base will engage with the groove turned
in the sensor.
After inserting the sensor in the clips, fit the external cover
as in Fig. 8.
