60 gauge readings

Read the upper scale only. Reverse the tubes when you turn the fan around to test in the other direction.

Taking Readings from Two Blowers

If one blower can't get adequate Room Pressure, remove the upper panel cover and install a second blower. To be absolutely sure the upper panel will stay in place during the test, tape the edges of the upper panel to the door frame using clear box sealing tape or masking tape. Don't use duct tape.

Adjust one or both speed controls until the Room Pressure is at the pressure requested by the Retrotec software. Ideally, adjust both blowers so that they are both running at about the same speed, and producing approximately the same Flow Pressure. Don't have one going flat out and the other idling. Both blowers must have their restrictor plates off, i.e. both on Range 22. Go through computer program per usual, but choose the

multi-blower check off.

Read the Flow Pressure from both blowers and enter them into the software separately. Do not add them! If you do not have 2 flow pressure gauges in your system, read the bottom blower, then unplug the clear tube #1 from the bottom blower and plug it into upper blower. Read the upper blower flow pressure. Don't touch the speed controls between reading one flow pressure and the other.

Enter the flow pressures one at a time. After entering them, you proceed as usual.
