Immersion Well Mounting (C7021D,
C7031D, C7031D, C7041D)
NOTE: The C7021D, C7023D, C7041D uses the
50001774-001 Well Assembly. See Fig. 5 for
dimensions.
The C7031D Sensor includes an immersion well. The
C7021D, C7023D, C7041D Sensors do not include a well;
order the well as an accessory (part no.: 50001774-001).
When used on a boiler, follow the manufacturer
instructions for location. If a tapped hole is not provided
for the immersion well, provide one as follows:
1. Drain boiler and drill a 23/32 in. (18 mm) hole at the
selected location.
2. Cut threads in the hole with a 1/2 in. (13 mm) by
14 NPT tap.
In other installations, mount the immersion well in an
elbow with a heel outlet as shown in Fig. 3.
1. Drain the system, if you have not already done it,
and open the tapped hole.
2. Put pipe joint compound on the threads of the
immersion well and screw it into the tapped hole or
elbow, tightening it securely.
3. Refill the system and check for leaks.
Mount the C7021D, C7023D, C7031D/C7041D into the
well:
NOTE: Mounting using previously installed
Honeywell wells (part no.: 32005960-001)
requires an adapter
(part no.: 50001775-001).
1. When an adapter is required, first thread it into the
well no more than one or two turns.
2. Slide the sensor into the well.
3. Rotate the sensor to thread it tightly into the adapter
and the adapter tightly into the well.
