Connecting Ancillary Equipment and Services
1.
Placement of Ancillary Components
Ancillary components not mounted to the tunnel must be installed close to the tunnel washer. The
locations for your system should be shown on the system layout drawings. Recommended
locations are also shown on the standard dimensional drawings for the tunnel and related
equipment.
Set the Mentor console on a flat surface. Bolt the console to the floor if desired. The following
ancillary components apply to conventional tunnels only, not PulseFlow tunnels: Install the reuse,
flow-splitter, and flow lifter tanks on grout so that they are level, cannot move, and sealed against
dirt and grime where the tank meets the floor. The top edge of the dam for the wire filter must be
level so that water is evenly distributed over the surface of the wire filter. Additionally the
flow-splitter and flow-lifter tanks must be low enough that the tank inlet is at or below the level
of the weir box outlet. Set all pumps flat on the slab so that they are as low as possible.

Plumbing Connections
The sizes and locations of utility connections vary with machine configuration. Those for your
system should be shown on the system layout drawings. The following general instructions apply
to all systems.
2.1.
Fresh Water
—Incoming fresh water connects to the fresh water header which connects to
each fresh water inlet. The following applies to 76032_ (G1) tunnels only: Although the ball
valve actuators are fitted with needle valves to adjust the rate at which the valves close, there is
some possibility that water hammer will be experienced if the incoming water pressure is above
50 PSI (345 Kpa) - especially if the water piping is small and/or not fastened securely. For severe
conditions it may be necessary to install pressure regulators and/or shock absorbers on the water
lines.
2.2.
Reuse Water
—On-site connections are necessary for some reuse water (example: water
returned to the reuse or pulse flow tank from the extraction system). This piping is shown on the
layout drawings for your system.
2.3.
Steam
—Connect main steam (at the steam strainer) to the tunnel washer steam header. Install a
manual steam shutoff valve so the steam valves can be repaired. Discharge condensate into the
tunnel drain trough. Do not return condensate to the boiler.
2.4.
Compressed Air
—Estimated compressed air consumption is approximately 5 SCFM per
minute at a minimum of 85 PSI.
2.5.
Drains for Discharged Water
—Consult local codes for equipment that can be necessary
(example: traps) when you connect to a sanitary sewer. In addition to the module outlets to the
sewer, the machine also has drain-off connections for water that drips between modules or units.
2.6.
Vents for Discharged Vapors
—Vapors generated in the oxidation zone and the finish
zone of the tunnel can mix together, produce noxious gasses, and corrode equipment. Without
adequate ventilation, these vapors will exit the tunnel discharge ring or concentrate in the
discharge end of the tunnel and adjacent press enclosure. The severity varies with chemical
composition and usage, but corrosion can be rapid and severe.
