N N o o t t e e : : Bridging between the unit main supports may
consist of multiple 2 x 12 boards or sheet metal
grating.
Arbitrarily adjusting the outside air dampers to open
fully when the return air dampers are closed or; failing
to maintain the return air pressure drop with the
outside air dampers when the return air dampers are
closed, can overload the supply fan motor and cause
building pressurization control problems due to
improper CFM being delivered to the space.
The outside air/return air damper linkage is connected
to a crank arm with a series of holes that allows the
installer or operator to modify the amount of outside
air damper travel in order to match the return static
pressure.
Refer to Table 48, p. 113
duct losses that correspond to each of the holes
illustrated in Figure 95, p.
To Adjust the Outside Air Damper Travel
1. Drill a 1/4" hole through the unit casing up stream
of the return air dampers. Use a location that will
produce an accurate reading with the least amount
of turbulence – several locations may be necessary,
then average the reading.

TERMINAL BLOCK OR UNIT
DISCONNECT SWITCH.
2. Close the disconnect switch or circuit protector
switch that provides the supply power to the unit
terminal block (2XD1 on 20-75T units / 1XD1 on 90-
130T units) or the unit mounted disconnect switch
(2QB1 on 20-75T units / 1QB1 on 90-130T units).
3. Turn the 115 volt control circuit switch (1S1) to the
"On" position.
Turn the 115 volt control circuit switch (1S20) to the
RT-SVX072A-EN
for the equivalent return air
112.
"On" position. (90-130T units only)
4. Open the access door located in the unit control
panel, and press the Manual Override key to display
the first service screen. Refer to the latest edition of
the applicable programming manual for
applications for the SERVICE TEST screens and
programming instructions.
5. Use tables in "," to program the following system
components for operation by scrolling through the
displays;
• Supply Fan (On)
• Variable Frequency Drive (100% Output, if
applicable)
• RTM Occ/Unocc Output (Unoccupied)
• Outside Air Dampers (Closed)
6. Once the configuration for the components is
complete, press the NEXT key until the LCD
displays the "Start test in __Sec." screen. Press the
+ key to designate the delay before the test is to
start. This service test will begin after the TEST
START key is pressed and the delay designated in
this step has elapsed. Press the ENTER key to
confirm this choice.
7. Press the TEST START key to start the test.
Remember that the delay designated in step 6 must
elapse before the fan will begin to operate.
8. With the outside air dampers fully closed and the
supply fan operating at 100% airflow requirements,
measure the return static pressure at the location
determined in step 1.
9. Press the STOP key in the unit control panel to stop
the fan operation.
