3.6.1.2 ENCLOSED
for units with an after-filter cabinet/enclosure, the after-
filters must be installed into this cabinet. The box-shaped
after-filter slides into the cabinet door on the cam-bars.
Be sure the filter(s) is pushed all the way to the back of
the cabinet where it will bottom out on a stop. rotate the
cam-bars upward as illustrated in figure 5B. this will seal
the filter’s top mounted gasket onto the cabinet’s upper
tube sheet.
3.7 DRAINS
All SHM units are supplied with 1-1⁄2˝ FPT drain
connections. A 1-1⁄2˝ drain trap or similar to prevent air
from being sucked up through the drain when unit is
running.
NOTES: Main drain line should be sufficiently sloped and
vented. all plumbing should conform with all
state and local codes.
appropriate design criteria as provided by a plumbing/
mechanical contractor should be utilized to ensure
proper control of drainage from the SHM unit.
4. UNIT OPERATION
4.1 START-UP
Before system start-up, verify that the installation is
complete per Section 3 of this manual. the following
are the basic steps to walk you through as you are
starting up.
1. open the SHM filter access doors and verify that the
filters are in place and properly sealed.
2. close and latch all access doors and electrical
enclosures on the unit.
3. ensure that the main power is connected and
turned on.
4. ensure that all circuit breakers are switched on.
5. follow Section 4.3 for setting changes on the touchscreen
to target the desired airflow volume. adjust the blower
speed to the rPM % that will provide the targeted
airflow. for assistance in determining the target rPM,
contact your local representative. When using the
auto flow option, follow the auto flow Settings in
Section 4.
6. Press the blower power button on the Home screen
to begin operation. note that if the oil mist collector is
connected to a process, other equipment will need to
be engaged as well.
7. Verify performance of the system by measuring
airflow or evaluating capture at each collection point.
it is recommended to record baseline performance
parameters so the system can be reset in case of an
upset condition or system change. the recorded data
should include:
• the static pressure at each collection hood
• system amperage draw and filter pressure drop at a
minimum
• any other key pieces of data critical to your process.
8. To optimize system performance and extend filter life,
run the unit at the minimum airflow required to control
the process.
4.2 SYSTEM OPERATION
as the SHM collects contaminate, a layer builds up on
the outside surface, causing an increased pressure drop
through the filters. as the differential pressure rises, the
blower rPM will need to be increased in order to maintain
the desired airflow. When the filters are saturated, the
contaminant drips to the bottom of the unit and collects
within the oil sump where it can be drained and disposed
of. When the system can no longer generate the airflow
required to capture or convey the collected contaminate,
the filters must be replaced.
4.2.1 AIRFLOW ADJUSTMENT USING
MANUAL SPEED CONTROL
the SHM features an electronically commutated (ec)
blower that is equipped with airflow adjustment using
the blower rPM. to adjust the airflow, the blower
speed (rPM) percentage can be adjusted from 20 to
100%. as filter pressure builds, it may be necessary
to increase the rPM to maintain proper capture and
transport velocity within the hood and duct system.
the adjustment of the rPM is done in the Blower display
screen.
4.2.2 AIRFLOW ADJUSTMENT USING
AUTO-FLOW CONTROL
With the auto-flow feature, the SHM will automatically
adjust the rPM of the blower to maintain the airflow set-
point. When the system can no longer maintain airflow, a
warning will be provided on the touchscreen. in the event
of a warning or failure on the touchscreen, refer to the
troubleshooting section of this manual to help determine
the cause and associated solution.
