Flow Offset Pressurization
1.
Shut OFF the main power
switch and disconnect the 110vAC power
source.
2.
Locate the Three-Motor Main Control Board
mounted under the power
switch cover.
3.
Locate the jumpers labeled JMP2 and JMP3
which determine the offset
between the two air streams at the highest air flow. Notice on the board
directly beside these jumpers are the numbers “0” and “1”. These
numbers refer to the position of the jumpers. The factory setting is:
JMP2 & JMP3 = 1, which means no offset is in effect and the unit will
provide a balanced & equal supply and exhaust flow.
4.
Move the jumpers
to their corresponding air flow offset as follows:
JMP2 & JMP3 = 1 No offset/ balanced flow default setting
JMP2=
1
, JMP3 =
0
~ 20 CFM Offset at HIGH flow
JMP2=
0
, JMP3 =
1
~ 40 CFM Offset at HIGH flow
JMP2=
0
, JMP3 =
0
~ 60 CFM Offset at HIGH flow
*Note: airflow is approximate
When dial is set at maximum high airflow, the unit will drop the exhaust
airflow by the specified amount. At lower airflow settings the air streams
will become proportionally closer together until they are equal at the
minimum low airflow (NO offset at lowest air flow no matter the above
selection).
