g)
Insert the union nut gaskets, attach the product to the pipe and
tighten the union nuts. Care should be taken not to exert pressure
on the pipe after connecting the product, as this may cause
leakages from the union nuts.

INSTALL TEMPERATURE SENSOR
a)
The temperature control sensor can be installed practically
anywhere. However, care should be taken to choose a place in
which the sensor will be fully immersed in the medium. The sensor
will not perform properly if it is installed in a place where it is likely
to overheat (i.e., near a heat source), or where it will be idle for
considerable periods due to the lack of flow of the medium.
b)
A 15 mm female threaded socket (for nominal diameters 15 to 25
mm) or a 20 mm female threaded socket (for nominal diameters 32
to 50 mm) should be welded to the pipe wherever the sensor is to
be installed.
The screw thread of the sensor connecting nut should be wound
with sealing tape and attached before inserting the sensor into the
socket. Finally, the sensor should then be secured with the
clamping screw.
DO NOT try to detach the temperature sensor from the temperature regulator.
Capillary tubes should be positioned where they will not get damaged easily
and where the ambient temperature is even. Capillary tube should NOT be
allowed to come into contact with things such as steam pipes or any other hot
surfaces.
Capillary tubes should never be cut, and should always be handled carefully.
Any excess tubing should be coiled up. In cases where capillary tubes need to
be bent or coiled, the smallest permissible bending radius is 50 mm.
Care should be taken when installing the temperature sensor, as only similar
types of materials can be combined. For example, if a non-ferrous
temperature sensor is installed in a stainless steel tank, electrolytic corrosion
is likely to occur, so it will be necessary to use a stainless steel thermowell to
protect it.
A thermometer should be fitted close to the temperature sensor to ensure that
the temperature settings are correct and that the product is functioning
properly.
The temperature around the product should never be allowed to exceed
80 ºC.
TEMPERATURE REGULATION
Turn the adjustment ring and use the scale markings to adjust the temperature.
There are
plus
(+) and
minus
(-) symbols printed on the cover to indicate how to
lower and raise the temperature: turning the adjustment ring towards the
plus
symbol will raise the temperature, whilst turning the ring towards the
minus
symbol
will lower the temperature.
A thermometer should be fixed near to the temperature sensor in order to fine-tune
the set point temperature.
CAUTION
