1. Vertical
tanks, horizontal tanks, or round tanks that are
empty or completely full,
just drop assembly into threaded tank
opening and screw down threaded bushing. Be sure that the corner of hexagon
bushing showing arrow points to center of long end of tank.
Be sure bushing is properly seated in tank flange before tightening
with wrench. If tank is partially full,
completely fill tank or completely empty tank before installing DU gauge.
2. After gauge is installed in tank,
locate the position for the outside reading indicator and wall bracket, then
attach wall bracket with screws.
3. Find location for hole for copper
tubing and beaded chain. (Preferably in the sill
between joists) drill or cut 5/8” diameter
hole or 1” hole if gauge is to be side mounted. (Fig. 1)
4. Measure length of tubing required
making necessary bends. Bends should be uniform with not less than 5”
radius.
5. Thread stainless beaded chain
through copper tube, start threading from gauge. Run beaded chain and tubing
through hole up to wall bracket.
6. Remove nut fastening housing
(Fig. 3&4) together. Set housing in bracket, place spring in housing (Fig.4).
Next thread chain through spring and through red indicator tube. Have
closed end (with chain connector) toward outside of building. This tube
should be set with line showing on the tube even with outside of housing
(A Fig. 4) . This applies if tank is empty.
7.Slide transparent plastic tube
over red indicator tube and spring, and press
the same end of housing (Fig. 4) over
transparent plastic tube. Check to see that reading is correct.
8.If reading is incorrect re-adjust
chain. Then cut off chain even with the end of the red indicator tube.
Fasten chain connector. Fasten outside housing (Fig. 3) to inside housing
(Fig. 4) with nut.

For underground tanks (Fig.2). The
above instructions for installation are the same.
If there are not enough
openings in underground tank, installation can be made
as shown in Fig.2 by using a Y
fitting on fill pipe or vent pipe. Opening must be 2”.
When ordering gauges for such
installations, it is necessary to give
dimension B (Fig. 2) from inside of
top of tank to top of Y fitting, and also
dimension of diameter of tank.
Lower portion of indicator housing is threaded to attach a 1/8” pipe.
