Large room testing with 2 Blowers

Models N64 and L64

Use the second blower panel. Install it above the lower blower
panel. Install the second blower in the upper panel. For added

security:

1. mount the panels on the far side of the doorstop so the

weight of the blowers pulls them into the stop

2. apply 2-inch clear tape to both sides of the upper panel

where it contacts the doorframe

Use second cord set from console to control the speed of blower #2.

Models E64 and J64

Use speed controls mounted on blowers to adjust speed.



Read flow pressure from blower #1 then move the flow pressure tube
from blower #1 and connect it to

blower #2 for second flow pressure reading.
