Example Combination Sash Fume Hood with Fixed Area.
16.
Measure the fixed area of the fume hood in square feet (m
2
). Any fume hood
leakage must be accounted for in this measurement. Set FIXED AREA to
this value.
NOTE: The fixed area of the fume hood is an area that remains open
regardless of sash position or movement. For example, most fume hoods
have an intake gap under the lower airfoil and above the cabinet of the fume
hood (typically a 1 inch gap). Also include 1% of the maximum open face
area in this calculation for other open areas, such as the space between the
sash and the track, and leakage.
17.
If the fume hood has a fixed panel in the sash opening of Segment A, locate
the position of the panel by measuring from the bottom of the sash opening
to the bottom of the fixed panel and enter the value into FPANEL POS A.
Measure the height of the fixed panel and enter the value into FPANEL HGT
A. Repeat step 17 for Segment B.
Sash Calibration
NOTE:
It is recommended that the vertical sash be calibrated before the horizontal
sashes.
1.
Set CAL SASH NUM to 1.
2.
Verify CAL SASH LOC is set to MIN.
3.
Slide vertical sash 1 to the closed position. Measure the distance from the
bottom of vertical sash 1 to the bottom of the sash opening in inches (cm).
Set CAL SASH POS to this value. When the SOAM accepts the reading,
CAL SASH POS will revert back to
257 and CAL SASH LOC will switch to
MAX.
4.
Verify CAL SASH LOC is set to MAX.
5.
Slide vertical sash 1 to the full open position. Measure the distance from the
bottom of vertical sash 1 to the bottom of the sash opening in inches (cm).
Set CAL SASH POS to this value. When the SOAM accepts the reading, the
maximum position value will be automatically entered into POS SASH 1 and
CAL SASH POS will revert back to
257, CAL SASH LOC will switch to MIN,
and CAL SASH NUM will return to
0.
