2.6 Connect Optional Exhaust Ducting
If the room the projector is installed in is not
equipped to ventilate up to 11,000 BTU (per
hour) the optional duct (P/N: 119-103105-
xx) must be installed to emit the constant
stream of warm exhaust air from the
projector to the outside of the building.
Connect pre-installed outside-venting
ductwork via the 8” inside diameter fireproof
ducting material attached to the top exit port.
Confirm that
1)
there are no obstructions or
‘kinks” within the ducting,
2)
all air intake
areas of the projector are clear and exposed.
The preinstalled outside-venting duct should
be rigid at the projector and must also
include a heat extractor/blower that
maintains at least 450 CFM (212 L/s) when
measured at the projector exhaust opening.
Calculating CFM in the 8” duct (Imperial): Use an anemometer to measure the ft/min or ft/sec at the rigid
end of the open duct that connects to the projector. Ensure the measurement is taken right at the very end and
without the projector connected. Then multiply the reading by the cross-sectional area of the 8” duct to
calculate the cubic feet/min airflow.
Imperial formula: Measured linear ft/min x 0.34 = CFM
Calculating the flow rate in the 200mm duct (Metric):
Use an anemometer to measure the air velocity in m/
sec at the rigid end of the open duct that connects to the projector. Ensure the measurement is taken right at the
very end and without the projector connected. Then multiply the reading by the cross-sectional area of the
200mm duct to calculate the airflow in L/s.
Metric formula: Measured linear air velocity m/s x 31.4 = L/s
Calculations should show 450 CFM (212 L/s) airflow in the 8”/200mm exhaust duct. DO NOT mount the
extractor on the projector as this may introduce some vibration into the image.
