Figure 103: Place Leveling Weight on Fulcrum
Making Level Adjustments
The DesignFlow unit is mounted so that it pivots at the top
when three lock nuts are loosened, two at the top and one at
the bottom of the assembly (see
involves precisely pivoting the assembly with a known force
applied to the vane until the vane opens to a specific position.
If after performing Steps 13 through 15 (previous pages), the
vane does not come to rest within the specified range, carry
out the following steps:
1. Unlock and open the louvered outdoor air intake door on
the side of the unit.
2.
Loosen the two 0.25-20 NC lock nuts at the top of the
3. Close and lock the intake door.
4.
Remove the cover from the access opening in the bottom
blade of the outdoor air intake louver (see
5. Loosen the 0.25-20 NC lock nut in the slotted hole at the
bottom of the DesignFlow frame (see
).
6.
If the
LH Lvl Pos=
(or
RH Lvl Pos=
) value obtained in step
15 above is HIGHER than the specified range, move the
bottom of the DesignFlow frame closer to the outdoor air
dampers (away from the back end of the unit). Do this by
turning the long adjuster nut to increase the L dimension
in
.
If the
LH Lvl Pos=
(or
RH Lvl Pos=
) value obtained in step
15 above is LOWER than the specified range, move the
bottom of the DesignFlow frame away from the outdoor
air dampers (toward the back end of the unit). Do this by
turning the long adjuster nut to decrease the L dimension
in
.
NOTE:
If the necessary adjustment cannot be made using
the long adjuster nut, reposition the two 0.25-20
NC jam nuts on the threaded rod to make larger
adjustments (see
7.
When finished making the adjustments, tighten the 0.25-
20 NC lock nut in the slotted hole at the bottom of the
8.
Gently rap the base frame to slightly vibrate the assembly
to encourage the vane to seek its equilibrium point.
9. Recheck the vane position compared to the range
specified in Step 16 (previous page). Readjust the level
as necessary.
10. When the level is correct, unlock and open the louvered
outdoor air intake door on the side of the unit and
tighten the two 0.25-20 NC lock nuts at the top of the
11. Close and lock the intake door.
12. Recheck the vane position and readjust the level as
necessary.
13. When the vane position is correct, replace the access
opening cover in the louvered door.
