•Read and experiment with each step
•To perform automatic or multi-point tests*, refer to
the Door Fan Software Manual and the DM-2
Operator’s Manual
*Tests for CGSB 149, LEED, ASTM E778, ASTM 1827,
EN13829, and ATTMA TS-1 may require more elaborate steps
and training. This guide is intended for familiarization with the
controls.

5 Pass red tube through panel
Pass the red tube from the DM-2 through the panel
and toss the end away from the fan’s airstream.
Note Water in the tube will result in erroneous readings.
6 Install fan
6.1 Hook the bottom of the fan inside the panel.
6.2 Align the notch on the upper rim of the fan with
the corresponding slot.
6.3 Gently push the fan into position and rotate it
slightly until the fan top is level with the floor.
6.4 Attach the fan safety strap.
7 Connect the fan
7.1 Connect the AC plug from the
wall to the variable speed
drive.
7.2 Connect the data cable from
the DM-2 to the drive.
7.3 The Power and Status lights
are steady green. A flashing green Status light
indicates no connection to the DM-2. A red
Status light indicates DM-2 control of the fan is
interrupted; reconnect, press [Exit] to clear.
7.4 Connect the yellow and green tube (3300SR
fans only) to the variable
speed drive and fan.
7.5 Connect the control
cable, twist it to lock,
to the fan top.
8 Zero gauge
Press [Auto Zero]. When “on”
is displayed, the gauge will
zero itself every 8 seconds.
Tip Normally, [Auto Zero] should be left “On”; turn off to save
battery power.
9 Set time averaging
9.1 Press [Time Avg] as needed, until
“PrA” varies by less than 1Pa.
9.2 Wait for twice the time average setting
before taking a reading.
Example: Set [Time Avg] to “8s” then watch for 16 sec.
Tip 1s, 2s, 4s, 8s updates every 1 second(s),
10s, 20s, 1min, 2min updates every 10 seconds.
Tip Use longer time averaging in windy conditions.
10 Measure bias pressure
10.1 Prior to each test, and with the fan covered,
press [Baseline] to begin averaging the bias
pressure.
10.2 Press [Enter] after about 60 seconds to
capture the “Baseline”.
10.3 After each test, press [Exit] to clear baseline.
Note The value displayed under “Baseline” will be subtracted
from the pressure reading on Channel PrA.
11 Set fan model on DM-2
11.1 Press [Device] until “Retrotec 3000” is
displayed.
11.2 Select “Retrotec 3000SR” if a yellow and a
green tube are connected to the fan.
Tip Disable the other devices using [Setup] to prevent the
incorrect flow curves from being accidentally accessed.
See: QuickGuide-DM2MkII
12 Set Range Plates and configuration
12.1 Remove range plates to get a higher range of
flows, add plates for a lower range of flows.
12.2 Start with Range B by removing the C8 Plate.
12.3 Press [Range Config] until the DM-2 displays
Range Config “B”.
See: QuickGuide-Fan-
RangeConfig-2000&3000
13 Choose results
13.1 Press [Mode] to cycle through the enabled
results.
13.2 Press [Mode] until “Flow” appears.
See: QuickGuide-DM2MkII
Page 2of 2

14 Set fan speed
14.1 Press [Set Speed] [10-100] [Enter] on the
DM-2 to set any speed from 10 to 100%.
Example: Press [Set Speed] [25] [Enter] to set the fan
speed to 25%.
Tip Monitor “PrA” to ensure that the pressure does not exceed
90Pa.
Tip Press [Exit] to turn the fan off.
14.2 Press [Jog/Hold] until “Jog” appears. This
enables manual fan speed adjustment.
14.3 Use [S] [T] to adjust the fan speed up or
down.
Tip Click once to change speed by 1%, hold button to
increment by 5%.
15 Set pressure automatically
15.1 Press [Set Pressure] [10-90] [Enter]. The
DM-2 will control the fan to achieve the set
pressure.
Example: Press [Set Pressure] [50] [Enter] to instruct
the DM-2 to attempt to achieve 50Pa building pressure.
15.2 Press [Jog/Hold] until “Jog” appears, to
enable manual pressure adjustment.
Tip Click once to change pressure by 5 Pa, hold to increment
by 10 Pa.
Tip Press [Exit] to turn the fan off.
16 Viewing flow at another pressure
16.1 Press [@ Pressure] until “@...” appears.
Flow is now calculated at the pressure
displayed after the “@”.
Example: 2190 cfm is the flow rate that would occur if the
exact test pressure of 50 Pa was achieved.
Tip It is difficult to achieve an exact test pressure especially
under windy conditions. Use “@ Pressure” to improve
accuracy; flow at the pressure following the “@” sign will
be displayed.
In [Set Pressure] mode, the “@ Pressure” can change
according to the target pressure which is very useful
when setting several different test pressures.
“Too Low” is displayed
If the pressure (PrA) has been reached, but “Too
Low” appears, the fan is running too slowly to
measure flow.
1. Press [Exit] to stop the fan.
2. Add the next smaller range plate.
3. Change the [Range Config] to match.
4. Restart the fan and try again.
Cannot reach target pressure (50Pa)
If the fan reaches 100% speed before reaching the
target “PrA” pressure:
1. Press [Exit] to stop the fan.
2. Remove a range plate, and change the [Range
Config] to match.
3. Start the fan and try
again.
Still cannot achieve target pressure
If the fan reaches 100% speed before reaching the
target “PrA” pressure and all of the range plates
have been removed:
Press [@ Pressure] to calculate the flow required to
establish the target pressure.
Example: 2200 cfm is the flow rate that would occur at 50
Pa even though only 42 Pa was achieved.
17 Flow at the pressure on channel “PrA”
17.1 Press [@ Pressure] until “@...” disappears.
Flow is now calculated at the pressure
displayed.
Example: 2262.8 cfm is the flow rate that occurred when
a test pressure of 53.0 Pa was achieved.
Tip CFM50 or cfm at 50 Pa is commonly used in the USA.
Simply establish 50 Pa and read the flow.
Tip The default @ Pressure settings can be changed by using
[Setup].

18 Flow (optional result)Flow (optional result) 22 Software results (optional)
22.1 Press [Mode] until “PrB” appears.
22.2 Input “PrA” and “PrB” into the software.
22.3 Press [Mode] until “Flow” appears.
18.1 Press [Mode] until “Flow” is displayed.
18.2 The DM-2 displays the current building
pressure and flow.
19 Air changes per hour (optional result) Tip Most multi-point tests are best done entering pressures, in
Pa, from both channels. In some cases flow or EqLA may
be entered. In these cases, the range displayed on the
DM-2 must match the range plate installed on the fan.
19.1 Press [Mode] until “Air Chg” is displayed.
19.2 Press [Enter] to input a new volume.
19.3 Input the building volume using the keypad
and press [Enter] to save. 23 Pressurization testing (optional)
23.1 Remove the fan from the door and install it so
that it is blowing towards you.
19.4 The DM-2 displays the air changes at the
current building pressure and volume.
Tip Change the units for volume in [Setup].
20 Leakage area (optional result)
20.1 Press [Mode] until “EqLA” or “EfLA” appears.
20.2 The DM-2 displays the building pressure and
the selected leakage area.
Note Equivalent Leakage Area (EqLA) is used in many
countries and standards to describe the leakage area in
terms of one large hole in a flat surface. Unlike flow,
EqLA is fairly consistent at different test pressures.
Note Effective Leakage Area (EfLA) is a different measure of
leakage area used by LEED and some other standards. It
is usually calculated at 4Pa. While EfLA can be read
directly from the DM-2, an accurate result will require a
multi-point test.
21 Other results (optional)
21.1 Press [Mode] to scroll through the remaining
modes.
21.2 Press [Setup], scroll to Mode Setup, and
press [Enter] to enable/disable other modes
or units such as:
Flow / area used by:
•ATTMA TS-1
(m3/h/m2at 50Pa)
•ASHRAE 90.1
(cfm/ft2at 75Pa)
•National Building
Code (l/s/m2 at 75Pa)
Leakage area / area used by:
•CGSB (cm2EqLA/m2)
•LEED (in2EfLA/ 100 ft2)
Note Area can be either the floor area of the building or the
surface area of the building and is changed in the first
menu displayed when [Setup] is pressed.
23.2 The DM-2 automatically
calculates the correct flow
using only the Red and
Yellow tubes, regardless of
the testing direction.
Note Testing with the fan turned around
normally requires the addition of an additional reference
tube. The Retrotec DM-2 does not require this tube.
24 Field gauge check recommended weekly
24.1 Insert a T in the
yellow tube.
24.2 Connect the red and
yellow ports to the T.
24.3 Increase the fan
speed and compare
PrA and PrB.
24.4 Disconnect tubes
from yellow and red
ports and connect them to green and blue
ports.
24.5 Repeat the test.
24.6 Values should be within 1% of each other.
25 Field system check recommended
25.1 Perform a door fan
test on the building
and record the EqLA.
25.2 Install cardboard in
upper part of doorway
with a 20 x 20 inch
hole cut in it.
25.3 Perform a second door fan test on the building
and record the EqLA.
25.4 The first result should be within 10% of the
second results, minus 400 in2.
