HEC and CEC Exhaust
1) Remove all items from shipping container and identify the following: Contents should include
Airgate, Airflow Monitor (AFM) with 1” [25.4mm] probe, #8-32 locknut, Cardboard protector sheet,
and Velcro Strip. (See Figure 2)
2)
Insert the 1” [25.4mm] long AFM probe into the shaft collar located on top of the airgate. The probe
has a long scratch mark on its side. Rotate the probe so the mark is positioned to the left side of the
shaft collar as shown in
Detail A . This will orientate the thermisters (glass beads) on the probe tip in
a horizontal plane so it can sense the airflow passing through it properly. Fully insert the probe so
the tip passes through the hole in the airgate approximately 3/32” [2.38mm]. Tighten the retaining
collar set screw carefully. Do not over tighten. (
Make sure not to rotate the probe while
tightening ).
3)
Remove the exhaust transition access panel and place to one side.( See Figure 1 ). Carefully place the
cardboard sheet provided on the filter face center. Grasp the airgate with your index finger inserted
into the front opening as shown in
Figure 3 . Carefully insert the airgate through the front access
opening. Once the airgate is completely inside exhaust transition turn the airgate to the left side of
the transition and slowly lower it onto the top seal panel locating the keyhole contour onto the far
left weld stud. Insert the #8-32 locknut provided leaving a 1/16 gap between the airgate flange and
the lower portion of the nut. Once the Airgate has been installed carefully slide cardboard protector
sheet to the right side of the exhaust filter and remove.
4) Run the probe wiring thru the slot located on the left side of the front access opening ( Figure 3). Re-
install the access panel to exhaust transition.
5) If the AFM is not factory installed, attach the AFM box to the cabinet with Velcro material provided
and plug its power supply in a wall outlet.
6)
When scanning the exhaust filter for leaks during future certification , scan the right side of the
exhaust filter first, then carefully slide airgate to the right and lift up over weld stud/locknut. There
is no need to remove the locknut as long as it is loosened properly. Continue sliding to the right side
of the unit in order to scan the remaining left side of the filter. Reverse directions after filter
scanning is complete.
AFM Calibration Steps (Low Flow Alarm Condition)
1) Confirm that the cabinet and exhaust system airflow are at the proper set point.
2)
For Hard Exhaust Connections (HEC), use the exhaust system damper to lower the exhaust flow
until the intake velocity is
80 fpm [0.406 m/sec].
3) For Canopy Exhaust Connections (CEC) and Exhaust To Room, open the light canopy, locate the
cabinet blower motor speed controller and record the voltage across terminals M1 & M2. Reduce
voltage to lower the intake velocity to
80 fpm [0.406 m/sec].
