1. Deburr the tubing ID and thoroughly clean the tubing threads.
2. Slip the gland nut and the collet onto the tubing.
3. Apply Pure Goop to the threads on the tubing. Screw the collar onto the threaded end of
the tubing leaving 1-1/2 to 2-1/2 threads exposed on the tubing between the collar and the
coned tubing.
4. Apply Pure Goop to the male threads on the gland nut and insert the tubing into the
connection. Engage the gland nut and tighten finger tight.
5. Tighten the gland nut to the torque specifications in Table 2-8.
When a flexible whip is used to allow cutting nozzle movement, anti-vibration fittings and proper
supports and guides must be provided to prevent failures from non-water related stresses. The
whip will only flex in a single plane without being subjected to torsional stress. The use of high
pressure swivels is strongly recommended.
2.9 Commissioning
When the machine has been positioned, all service connections installed, and the high pressure
plumbing has been installed to the cutting area, the machine is ready to be commissioned.
If normal operating pressure will not exceed 50,000 psi (3,447 bar), the alternate
inlet poppet valve must be installed before proceeding. Follow the procedure Low
Pressure Inlet Check Valve, Section 8, High Pressure Water System. Refer to
Table 11-4, Section 11, Parts List.
The following procedure is used for the initial startup and testing of the machine.
1. Check all areas in and around the pump for foreign objects and debris. Remove all tools,
parts, etc. from the area.
2. Check the hydraulic fluid level. The hydraulic system is pre-filled prior to shipping. If
the hydraulic fluid is low or empty due to leakage during transit, the system must be filled.
Follow the instructions in Section 5, Recirculation System.
3. Prior to shipping, a plug was installed in the breather location on the reservoir. Remove
the plug and install the breather.
4. Open the shutoff valves on the service connections and check for leaks.
5. Check the connection between the customer supplied, main power disconnect and the
machine. Verify the proper voltage supply. Turn the control power on and select low
pressure operation.
