3.7 DRAINS
All SHM units are supplied with 1-1⁄2˝ FNPT drain
connections. a drain trap or similar is to be utilized 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. ensure that all circuit breakers are switched on.
3. ensure that the main power is connected and
turned on.
4. close and latch all access doors and electrical
enclosures on the unit.
5. Blower rotation should be checked on all Basic units.
the blower should be turning counterclockwise when
viewed from above.
6. on advanced units 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 4.3.4 refer to figure 19.
7. Press the blower power button on the Home screen
to begin operation on advanced units. note that if
the oil mist collector is connected to a process, other
equipment will need to be engaged as well. on basic
units the motor starter switch or disconnect should be
switched on.
8. 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.
9. 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 equipped). a damper
is to be used to control flow on all basic SHM units to be
supplied by the customer. 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 ADVANCED UNIT OPERATION
4.2.1.1 AIRFLOW ADJUSTMENT USING
MANUAL SPEED CONTROL
the advanced 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, see figure 9.
4.2.1.2 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. refer to figures 11 & 19. 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.
