c. The cover filter is the largest circular filter. It has a steel ring located at both the
inside and outside diameters. This filter is also held in place with tabs to prevent it
from falling off during routine use.
2. All filter elements should be cleaned periodically. This can be accomplished by
dipping the filter elements into a water-based detergent bath. This will clean the
filter element adequately for immediate installation and use.
1. Care should be taken when handling the filters so as not to tear or puncture them.
2. Fine sludge particles may tend to accumulate within the pan cover’s wire mesh element.
This should be checked daily and cleaned if necessary to insure efficient extraction of fluid
from the sludge.
CARE OF PAN
From time to time inspect the pan and pan cover for accumulation of sludge between the ribs of
the pan or cover.
If neglected, this will affect the extraction efficiency by blocking the
escape path for the spun off liquid
. Clean out any accumulated sludge as required.
LOADING AND OPERATING
When operating this machine, use care to load the pan evenly to insure a good running
balance. Make sure that all guards and covers are in place.
1. Before operating the machine be sure that provisions have been made to capture the
extracted liquid from the outlet at the rear of the machine.
2. Adjust the cycle timer(s) 1TRE, located within the control panel. Barrett recommends an
initial setting of 30 minutes with water-based sludge and 45 minutes with oil-based sludge.
The required cycle time will vary with the application and must be determined through
experimentation. Close and latch the control panel’s door.
3. Turn on the power at the main disconnect. The green
OPEN
light will illuminate within 20
seconds.
NOTE
: The machine is wired so that the cooling blower (if so equipped) must be on
for the machine to operate.
4. Unlatch and open the machine’s lid. Remove the pan and pan cover from the machine.
USE CAUTION WHILE OPERATING ANY MACHINERY AND THINK ABOUT THE WORK
YOU ARE PERFORMING!
5. Locate a pan already full of sludge or load the wet sludge into a pan.
If your machine is a model #401-SE or 1101-SE the pan proper contains no filter
elements.
If your machine is a model #401-SES or 1101-SES the pan should be lined with filter
elements. The elements attached to the side of the pan need to be adjusted before
