Assembly, Installation, Operation, & Maintenance Instructions
This instruction sheet is to be used in conjunction with assembly drawing 299-11 EL. Item
numbers referenced below are called out on the drawing along with the appropriate weld locations
and symbols. Assembly and field fabrication is to be accomplished as follows with tubing
components laid out horizontally:
Assembly:
(1) Insert lower end of Upper Waterway Weldment Sub-Assembly (Item 18) into the upper end
of Lower Waterway Weldment Sub-Assembly (Item 22) for a length of twelve inches.
(2) Weld upper and lower waterway sections together by making continuous 3/8” bevel weld at
top end of Lower Waterway Weldment Sub-Assembly (Item 22).
(3) Slide Lower Horizontal Drive Sleeve Assembly (Item 23) over waterway section over
waterway piping. Grinding of weld made in step 2 above may be necessary in order to
provide clearance for bushed lower end of the horizontal drive sleeve. Slide this sleeve as
far as possible toward flanged end of waterway.
(4) Slide Upper Horizontal Drive Sleeve (Item 17) over waterway tubing and into socket end of
Lower Horizontal Drive Sleeve.
(5) Install Monitor Sub-Assembly (Item 16) onto Upper Waterway Weldment Sub-Assembly
(Item 18), by wrenching Monitor Base onto Upper Waterway Weldment. Use a good grade
pipe joint compound on the pipe threads.
(6) Slide both sections of Horizontal Drive Sleeve (Items 17 & 23) toward monitor so that
upper end of Drive Sleeve (Item 17) slides over the monitor lower swivel joint. Align two
holes in Drive Sleeve (Item 17) with two tapped holes in monitor swivel joint. Secure drive
sleeve to monitor swivel joint using two ¾ - 16 x 1.00 bolts. Apply Loc-Tite #262 to bolts
prior to assembly.
(7) Assemble Horizontal Control Arm & Vertical Lock Assembly (#81310001) to Lower Drive
Sleeve (Item 23).
(8) Rotate Lower Horizontal Drive Sleeve (Item 23) to align vertical control handle with
monitor discharge port. Support section of horizontal drive sleeve as necessary to align
sections prior to welding.
