Retrotec 5000 Blower Door with DM32 - Manual (Page 3)

Show leakage area Result
Tube configuration is the same as the depressurization
test.
Required by many
states. Also available in
metric units.
Normalized leakage
area is used in many
standards. All common
units are available.
Air Changes per hour
can be shown
directly on the gauge.
Enter volume as shown
below.
Specialized units such
as Effective Leakage
Area are also available.
Pressurization test
Turn the fan around to blow air into the house.
Adjust fan with gauge
Tap [Stop] to turn the fan off.
Connect Speed Control Cable to the fan.
Solid green Status light indicates gauge is connected.
CAUTION: Doors opening during the test will cause
fan speed to increase which will create a pressure pulse
when that door is re-closed, disturbing dust, soot, and
particulates, causing damage. STOP the Fan if a door
opens.
When [Set Speed] or [Set Pressure] is used, the Jog
keys become active on the Home screen. Use the
[JogUp] [JogDown] arrow keys to increase or decrease
the target by 5 Pa or 1%.
Adjust fan speed remotely
When a Result is chosen that requires an
area or volume, [Area] or [Volume] will
be shown on the Home screen.
Tap [Area] or [Volume] to change . The
area and volume can also be changed
from the [Settings] menu.

Equivalent Leakage Area (EqLA) describes the leakage
area in terms of one large hole in a flat surface.
Tap the [Channel B] key, then , and select
“EqLA: sq in”
[Channel A] shows the building pressure and
[Channel B] “EqLA” shows the combined size of all
holes in the building.
Leakage area is not a required result, but is a nice way to
visualize the size of the hole in the ducts.
