IImmppoorrttaanntt:: This procedure is for A&B cabinets (20–
55 Ton) only.
4. Compare the static pressure reading to the static
pressure ranges and linkage positions in Table 17,
p. 51 or Table 18, p. 52 for the unit configuration,
unit size and operating CFM.
If the static pressure reading is greater than the
pressure listed in Table 17, p. 51 or Table 18, p. 52
for outside air damper position 1 then relocate the
outside air connecting rod to balance the outside air
damper pressure drop against the return static
pressure, using the following steps.
If the static pressure reading is less than the
pressure listed in Table 17, p. 51 or Table 18, p. 52
for outside air damper position 1, then determine
the appropriate pressure increase needed. Identify
the correct return damper linkage location using
Table 19, p. 52. Then, relocate the return air
connecting rod to balance the outside air damper
pressure drop against the return static pressure
using the procedure starting in Step 10. If no
adjustment is necessary, proceed to the last step.
5. On the outside air damper remove the drive rod and
swivel from the crank arm(s). If only one hole
requires changing, loosen only that end.
6. Manually open the outside air dampers to the full
open position.
7. Manually close the return air dampers.
8. Reattach the drive rod and swivel to the appropriate
hole(s). The length of the drive rod may need to be
adjusted to align with the new hole(s) location. If so,
loosen the lock nut on the drive rod against the
swivel. Turn the swivel “in” or “out” to shorten or
lengthen the rod as necessary. For some holes,
both ends of the rod may need to be adjusted.
9. Tighten the lock nut against the swivel(s). Proceed
to the last step.
10. On the return air damper remove the drive rod and
swivel from the crank arm(s). If only one hole
requires changing, loosen only that end.
11. Manually open the return air dampers to the full
open position.
12. Manually close the outside air dampers.
13. Reattach the drive rod and swivel to the appropriate
hole(s). The length of the drive rod may need to be
adjusted to align with the new hole(s) location. If so,
loosen the lock nut on the drive rod against the
swivel. Turn the swivel “in” or “out” to shorten or
lengthen the rod as necessary. For some holes,
both ends of the rod may need to be adjusted.
14. Tighten the lock nut against the swivel(s).
15. Plug the holes (made during Step 1) after the proper
adjustments have been made.
