Under Negative Pressure
If the condensate tray is located at the inlet side of the fan (i.e. under
negative pressure) then calculate the values of A & B as shown below
(Figure 7).
10Pa = 1mm H2O
A = Fan inlet pressure (mm H2O) +25mm (minimum). Allow 100mm
for these units if pressure is unknown.
B = A/2 (minimum).
Under Positive Pressure
If the condensate tray is located at the outlet side of the fan (i.e. under
positive pressure) then calculate the values of A & B as shown below
(Figure 7).
A = 25mm (minimum).
B = Fan outlet pressure (mm H2O) + 25mm (minimum).
Allow 100mm for these units if pressure is unknown.

3.7 Fan Transit Brackets (AC Motors)
Transit brackets are factory fitted to prevent the blowers moving during
transport and must be removed to prevent excessive vibration during
operation. The specific location and number of transit brackets varies by
unit. Check the unit drawing for the location and number of blowers.
Before use ensure the transit brackets have been removed from each
blower within the unit (Figure 8).
•
Loosen and remove the transit bracket bolt.
•
Remove the transit bracket away from the anti-vibration mount.
Repeat for each bolt.
•
Store the transit brackets and bolts in a safe location if required for
future use.
