Airflow
Airflow should be occurring in both airstreams. Sometimes the
easiest place to confirm that air is moving is at the external
wall caps.
If exact airflow is critical, it may be desireable to permanently
install flow measuring stations and manometers. These can
also be used to determine when filters should be cleaned or
changed.
Use Static Taps to Measure Airflow Rates
See "Cross Core Static Drop" in MEASURING AIRFLOW table on
Page 6.
Use Damper to Balance Air Flow to Desired Rates, if
necessary
The TR's blower motor are well suited for volume control by
dampers on the inlet of the units. One balancing damper is
provided in the units parts tray. NOTE: The unit is considered
balanced if the difference between the two airflows is not more
than 10 CFM.
After measuring the airflow of the units, the balancing damper
may be used to blance airflow if desired. Place the damper
between the duct collar and the unit for the outlet of the
airstream recording higher flow. NOTE: Install the damper so
that it slides from the door of the unit down to the duct collar.

Slowly move the damper further into the duct until the desired
airflow is recorded. Secure the damper in place using 1/8" tek
screws (provided). NOTE: Drilling through the case while the
unit is running may cause metal shards to be drawn into the
unit.
Equipment Required
• A magnahelic gauge or other device capable of measuring 0
to 1.0 in. water of differential pressure.
• 2 pieces of natural rubber latex tubing, 1/8" ID, 1/16" wall
works the best.
NOTE: be sure to remove cap from pressure port before
inserting tubing. Insure tubing is well seated in pressure ports.
NOTE: The tubing should extend into the pressure port
approximately 1 inch.
