Installation
The Gauge Head
2. For 9701/9702 ion chamber detectors, partially assemble the two
tensioning bolts (hardware kit 885825) in the following order:
a. 1 tensioning bolt (large)
b. 1 flat washer: Place onto bolt next to bolt head.
c. 1 spacer ring
d. 2 Belleville washers with concave sides together
e. 1 special nut: Thread nut securely onto the bolt end.
3. For 9719B/9720B scintillation detectors, partially assemble the two
tensioning bolts (hardware kit 885826) in the following order:
a. 1 tensioning bolt (large)
b. 1 chain: Place center ring of chain over the bolt head.
c. 1 bar nut: Position the guard tube towards the bolt head.
d. 1 special nut: Thread the nut securely onto the bolt end. After the
special nut is fully threaded, thread the bar nut back down the bolt
so that it rests against the special nut.
4. From the pipe side of the source mounting plate, thread one end of a
chain through the plate’s top keyhole opening until you reach one of
the four end links you marked in step 1. Engage this link by sliding it
into one of the keyhole slots.
5. Thread one end of the other chain through the bottom keyhole and
engage the marked link as you did with the top chain.
6. Position the source housing mounting plate on the pipe. If necessary,
use a lift, hoist, or other means to hold it in position.
7. Pass the center part of the upper and lower chains around the pipe and
thread their ends through the corresponding keyholes. Engage the
marked links in the empty slots.
Note All four chain ends must engage at the same link. If you make an
adjustment, adjust all four chain ends by the same amount. Also make sure
there are no twists in the chain as you wrap it around the pipe. Otherwise
the gauge head will not be aligned correctly.
