5.8.6.2 Taking readings at the reclaimer door:
Open
the reclaimer fill door, remove the needle protector, and
place the needle so the tip is inside the door opening.
Carefully close the door on the needle. The side of the
needle will embed into the rubber, creating an airtight seal.

5.8.6.3 Taking frequent readings using a permanent
fitting:
A permanent fitting may be installed in the
reclaimer wall, as shown in Figure 21, for taking frequent
static-pressure readings. Permanent fittings must have a
barb to accommodate the 3/16" ID tubing and have a
means of sealing the fitting when the manometer is not
in use. Use silicone sealer or other sealant to seal
around the fitting to prevent leaks. The fitting should be
capable of being capped when the manometer tube is
removed. Sealing the fitting will prevent leaks that alter
the reclaimer’s separation efficiency. Air drawn into the
reclaimer will cause carryover of good media to the dust
collector.
5.8.7
Adjust the slide rule to align the zero with the
fluid level. Refer to the upper part of Figure 22.
5.8.8
Open cabinet doors and turn the exhauster ON.
The negative (static) pressure will move fluid in the tube.
NOTE: Readings must be taken with the cabinet
doors open and with the exhauster running.
5.8.9
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 22.
5.8.10
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.

Foot Shelf, Ergonomic Models Only
5.9.1
Raise the shelf to remove pressure from the
locating pins and remove the pins. Adjust the shelf
height and insert the pins.

PREVENTIVE MAINTENANCE
WARNING
Failure to wear an approved respirator and
personal protection when servicing dust-laden
areas of the cabinet and dust collector, as well as
when emptying the container, can result in lung
disease, serious skin or eye irritation, or other
health issues. Toxicity and health risk vary with
type of media and dust generated by blasting.
The respirator must be approved for the type of
dust generated. Identify all material being
removed by blasting and obtain a safety data
sheet (SDS) for the blast media.
To avoid unscheduled downtime, establish an inspection
schedule. Inspect all parts subjected to media contact,
including the gun and nozzle, media hose, flex hose,
wear plate, and all items covered in this section. Adjust
frequency of inspections as needed, based on the
following:
With the exhauster OFF,
slide the rule to align the
zero with the fluid level.
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 reading together. In the example, the
static pressure is 3-1/2".
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.
The manometer must be vertical
when taking pressure readings.
