Elkhart Freestanding Assembly & Installation Instructions

This instruction sheet is to be used in conjunction with assembly drawing (below). Item numbers referenced below are called out on the drawing along with appropriate weld locations and symbols. Assembly and field fabrication is to be accomplished as follows with the tubing components layed out horizontally:
  1. Insert lower end of Item 12, Upper Waterway Weldment Sub-Assembly into the upper end of Item 14, Lower Waterway Weldment Sub-Assembly 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 Item 14.
  3. Slide Lower Horizontal Drive Sleeve and Control Handle Sub-Assembly (Item 15) 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 (Item11) over waterway tubing and into socket end of Lower Horizontal Drive Sleeve.
  5. Attach Monitor Sub-Assembly #80701 to upper end of waterway by wrenching Item 8, Monitor Base. Use a good grade pipe joint compound.
  6. Slide both sections of Horizontal Drive Sleeve (Items 11 & 15) toward monitor so that upper end of drive sleeve (Item 11) slides over the monitor lower swivel joint. Align two holes in upper end of drive sleeve (Item 11) with two tapped holes in monitor swivel joint. Secure drive sleeve to monitor swivel joint using two 3/4 - 16 x 1.00 bolts. Apply Loc-Tite #262 to bolts prior to assembly.
  7. Rotate Lower Horizontal Drive Sleeve (Item 15) to align vertical control handle with monitor discharge port. Make sure that ends of upper and lower sections of horizontal drive sleeve abut each other within the lap joint sleeve. Support sections of horizontal drive sleeve as necessary to align sections prior to welding.
  8. Join upper and lower sections of horizontal drive sleeve (Items 11&15) by making continuous 1/8" bevel weld at top end of lap joint sleeve.
  9. Attach vertical control cables (Item 16) to monitor and vertical control handle as shown on drawing. Adjust cable lengths so that handle is parallel to stream direction.
  10. Attach nozzle to monitor discharge port. If adjustable fog nozzle is used, attach pattern control cable to nozzle.
  11. When raising the monitor assembly, do not attach cable ors ling to bent tube waterway at top of assembly. This portion of the assembly is not designed to support the weight of the long riser, and damage or failure could result.

Installation
The supply pipe and companion flange configuration to which the monitor is installed must be supported to withstand a bending moment of 10,000 ft.-lbs. applied to the flange face. A forged steel companion flange and steel pipe with adequate support are recommended. Do not use cast iron companion flange or cast iron pipe. Join monitor base flange to companion flange using 3/4-10 SAE Grade 5 bolts and nuts. Use a 1/16" thick ring gasket designed for use with steel flanges. Torque flange bolts to 200 ft.-lbs.

Important
Do not exceed the following maximum allowable flow rates at 100 psi nozzle pressure:

Monitor Height Max. Flow @ 100 psi NP
25' 500 gpm
30' 500 gpm
40' 350 gpm

Pressure and flow characteristics of water supply must be determined prior to monitor installation and a restricting device, such as an orifice plate, installed between flanges to limit flow and pressure to appropriate values as indicated above.

NOTE: 
1) 25 & 30 foot units 500 gpm max.
2) 40 foot unit 350 gpm max.
3) These max flow rates to be developed with a max. nozzle pressure of 100 psi.
