WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when
exposed to live electrical components could result in
death or serious injury.
When it is necessary to work with live electrical
components, have a qualified licensed electrician or
other individual who has been properly trained in
handling live electrical components perform these
tasks.
WARNING
Rotating Components!
Failure to disconnect power before servicing could
result in rotating components cutting and slashing
technician which could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized.
Important:
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
or
for the unit configuration, unit size
and operating CFM.
If the static pressure reading is greater than the
pressure listed in
or
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
or
for outside
air damper position 1, then determine the appropriate
pressure increase needed. Identify the correct return
damper linkage location using
. 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
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.
