GENERAL
Temperature
variations sensed by the
liquid-
filled
bulb
are hydraulically
transmitted through
the capillary
to a stainless steel
diaphragm
capsule. The
capsule
operates a lever to
actuate
one or
two snap-action
switches.

Fully
immerse
the
bulb and 6" capillary
in the
control
zone. For
best results it
is
generally
desirable
to
place
the
bulb close to
-
(but
noi
touching)
the heating
or cooling
source in
order
to
sense
temperature
fluctuations
quickly.
Place
the remäining
capillary
adjacenf
to tñe
control
head
so
that
it
will
sense the
same
ambi-
ent
temperatures.
Factory
calibration,
unless
spe.cified
othenrrrise,
allows for

tube
in
the
sensed
medium.
If more
than

may
be
necessary,
in
which
case follow
procedures
out-
lined
in Part ll.
"C"
style bulbs

can be
coiled
or
shaped
to fit the installation.
Avoid

Do not

"B".style
bulbs
(3/8"

bending
or
coiling

Exercise caution
when
making
bends
near
the
capillary ends. lf
a
separable well

instruc-
tions included.
