2. Install the two rod guides (Item 24) onto the 4” pipe using the U-bolts and nuts
provided. The upper rod guide should be located 1/3 of the distance measured in
step 3 from the upper sleeve (Item 27). The lower rod guide should be located 1/3 of
the distance measured in step 3 from the upper rod guide. (The maximum distance
between rod guides is 10 feet. Add additional rod guides as needed to meet this
requirement.)
3. Paint the 4” pipe section of the assembled unit with paint suitable for the environment
and let dry.
4. Assemble the lower 90º gear case sub-
assembly to the 4” pipe using the two U-bolts
and nuts provided. Locate it 3” to 4” above the lower gearcase & base assembly with
the sleeves (Items 21 & 27) aligned.
5. Measure the distance from the center of lower sleeve (Item 21) to center of upper
sleeve (Item 27). Provide 5/8 dia. brass or stainless steel rod to this length.
6.
Loosen the two U-bolts and slide the lower 90º gear case down against the monitor
base assembly. Insert one end of the 5/8” rod through each of the rod guides and
into the upper sleeve (Item 27). Position the 5/8” rod and the rod guides on the 4”
pipe so the 5/8” rod is aligned with the upper sleeve (Item 27). Move the lower 90º
gear case into position so the lower sleeve (Item 21) will slip onto the lower end of
the 5/8” rod and slide it up onto the 5/8” rod as far as possible. The 5/8” rod should
be loosely bottomed in both the upper and lower sleeves. Align lower 90º gear case
and rod guides so the 5/8” shaft(s) are in line as shown on the drawing and tighten
the U-
bolts around 4” pipe. Position rod guides and tighten U-bolts.
7. Use the hole located on one side of the upper and lower sleeves (Item 21) and (Item
27) as a guide and drill a 3/16 hole through the 5/8” rod and out through the other
side of each sleeve. Insert a roll pin (Items 20 & 28) in each of the newly drilled
holes.
8. Assemble the nozzle (see installation instructions included with nozzle).
9. Grease all bearings at grease fittings using a good grade of waterproof grease. Put a
heavy coating of silicone grease on all exposed gears and worms.
10. Turn hand wheels for elevation and horizontal control to check unit for free operation.
11. Assemble unit to standpipe and attach support bearing(s) if required.
12. Run water through monitor and nozzle at rated volume and pressure. Operate
monitor through its entire range of motion as final check of proper alignment and
operation.
