4.3.8
To find the static pressure, add the number of
inches the fluid travels up one column to the inches the
fluid travels down the other column. Refer to the example
in Figure 8.
4.3.9
After taking the readings, replace the needle
protector. Close the manometer valves and store the
manometer in the original container in a clean area.
NOTE: If the manometer installation is permanent, the
manometer may remain on the reclaimer body after the
valves are closed.

Air Jet Adjustment
‒ Figure 9
4.4.1
Thread the air jet 4-1/2 to 5 full turns into the gun
body. Doing so will leave 3-1/2 to 4 threads exposed past
the lock nut. Tighten the lock nut to maintain the setting.
Refer to Section 8.2 for optional adjusting tool, which
correctly positions the jet. Instructions are provided with
the tool.

Door Interlocks
‒ Figure 10
Never bypass the door interlock system. Doing
so can result in serious injury from unexpected
blasting.
4.5.1
The door interlock disables the blasting control
circuit when the door is open. To enable blasting, the
door-interlock switch must be engaged when door is
closed. The interlock is set at the factory and does not
normally require field adjustment unless parts are
replaced. When adjustment is required, proceed as
follows.
4.5.2
Close cabinet door.
4.5.3
Turn the adjusting screw in or out as required to
engage the switch without applying excessive pressure
on it. Tighten the adjusting screw nuts.
Lock Nut
Air Jet
3-1/2 to 4 threads between
lock nut and air
jet hex.
The manometer must be vertical
when taking pressure readings.
With the exhauster OFF,
slide the rule to align the
zero with the fluid level.
To obtain the pressure reading: With
the exhauster ON, add the number of
inches the fluid travels up the column
to the inches the fluid travels down
the other column. The total is the
static pressure reading.
In the example shown, fluid traveled up
the right column 1-3/4",
and down the left column 1-3/4".
Static pressure is determined by adding
the columns together. In the example,
the static pressure is 3-1/2 ".
