Installation
Varec, Inc. 25
11. Thread the float cables into the tank through the top anchor fittings. Fasten them to the
bottom cable anchors with the furnished hardware.
12. Thread the upper end of each guide cable through the top anchor assembly. Hand tighten.
Use the lock nut to lock the cable in place, then tighten the adjustment nut, until the guide
cable is tensioned by the spring.
13. Replace the housing nipple and cap.
14. Apply appropriate pipe thread compound and install the sheave elbow on the vertical pipe
to the tank interior. Install a pipe union in the horizontal pipe run, in order that the elbows
can be easily removed, if necessary. Then install the horizontal pipe assembly into the tank
drop elbow. Adjust the length as needed to properly position the outboard elbow.
15. Install the outboard elbow on the horizontal pipe.
16. Apply pipe thread compound and screw the gaugeboard connector pipe into the outboard
elbow.
17. Remove the bolts, cover, and gasket from the outboard elbow and drop a plumb line
through the center.
18. Drop a chalk line from the top of the tank parallel with the plumb line and mark the chalk
line on the tank wall. See Figure 9 on page 18.
19. Use the width of the gaugeboard at the bottom of the tank wall and chalk register marks
for the width centered on the chalk line.
20. Do the same at the top of the tank.
21. Make chalk line marks between the top and bottom register mark to aid in keeping the
gaugeboard sections centered and parallel during installation.
22. Bolt the gaugeboard support brackets into position (see Figure 9 on page 18). The first
gaugehead support bracket mounts near the top of the tank. The others are spaced at
seven foot [2.13.m] intervals except for the one at the bottom of the tank.
23. Use the “U” bolt and nuts (see Figure 9) to attach the gaugeboard connector to the pipe.
The pipe should extend one inch [25.4 mm] below the “U” bolt.
24. Attach the top section of the gaugeboard to the connector plate. Make certain that it is
centered on the chalk line.
25. Attach the remainder of the sections to the bottom of the tank. Make certain that each
section is centered on the chalk line (see Figure 9 on page 18).
Note To fit the gaugeboard to the tank, cut the lowest gaugeboard section at the marker
that is 4.50 inches greater than the tank height to adjust the fit to the total height to the
tank
26. Tilt the float on edge and slip the guide cables through the loops on the inside of the tank.
Set it on the tank bottom with the tape/cable connection up.
27. At the elbow on the tank entry pipe, unroll one or two turns of the tape/cable and start to
feed it into the horizontal pipe. Continue to unroll the tape/cable several turns at a time
until it reaches the ground at the bottom of the gaugeboard installation position. Make
sure that the tape/cable on the ground does not become kinked or dirty.
Note Throughout these instructions the term “tape/cable” is used to designate either
the indicator cable drive or the combination tape and cable drive that is used to also drive
the accessory drive elbow. If the tape/cable combination is used, the cable end goes on
the gaugeboard side.
