1.0 APPLICATION
1.1 The CA1001 is used around the capillary tube of an
AR or ARC control to hold the bulb into a well, or seal the
bulb into a tank.
1.2 AR thermostats with style 4 bulbs include a factory
installed non-removable stuffing box that may make the
use of a CA1001 unnecessary. AR thermostats style 9,
ARC limits and all thermostats and limits with optional
moisture resistant and explosion resistant enclosures
will require the CA1001 stuffing box if used as described
in 1.1.
1.3 It is always advisable to use a thermostat well where
high pressures, corrosive material or high or varying flows
are involved. Without a well, a leak or defect in the
thermostat would necessitate shutting down and drain-
ing the system. However, it should be noted that the use
of well may slow down the response time and increase
controller differential.
2.0 INSTRUCTION
2.1 The parts included with this kit are shown in Fig. 1.
2.2 Slide the small brass bushing over the bulb and onto
the capillary and position out of the way. The hex should
be towards the control and threads towards the bulb.
2.3 Slide the large brass bushing over the bulb positioned
with the hex facing the control.
2.4 Drop 3 split washers around the capillary and down
into the hollow of the large compression fitting. It is very
important for a liquid light seal that the slots are
positioned alternately 180° from each other per Fig. 1.
2.5 Wrap the 5" graphite impregnated cord tightly around
the capillary and push it tightly into the compression fitting
hollow with a blunt tool being careful not to damage the
capillary.
2.6 Put at least one split washer in place and temporarily
thread the small bushing into place inside the large bush-
ing. This will help to compact the cord into a liquid tight
seal. Remove the small bushing, add the remaining 2
split washers again being sure to stagger the slots 180°
apart and reinstall the small bushing semi tight.
2.7 Position the assembly to the correct position on the
capillary, tighten the large bushing into its mounting
position in the tank or process, then tighten down the
small bushing to ensure a liquid tight seal.
2.8 If using the stuffing box assembly for mechanical
holding only in an air system or in a thermostat well the
extra care of assembly described in 2.4 thru 2.6 is not as
critical.
