The concealed duct unit has 7 steps of static pressure (MMD-AP0076 ~ 0186BHPUL is 0.12 – 0.6 in. WG,
MMD-AP0216 ~ 0546BMPUL is 0.12 – 0.8 in. WG) adjustment to meet the installation site requirements /
conditions.
With these steps there are different speed fan taps associated to select correct air fl ow.
For meeting the site requirement / conditions, make sure the external static pressure and air fl ow are determined.
Plot the external static pressure and air fl ow on the below graph to determine the right speed fan step setting.
For example : Job site requirement is to deliver 400 CFM at 0.4 in. WG external static pressure. Using the below
graph, external static pressure on vertical axis and air fl ow on horizontal axis, the star mark indicates the job site
requirement.
The star mark is below 0.6 in. WG high speed fan tap line, which means the unit needs to be set to 0.6 in WG
external static pressure with high speed fan tap.
Please follow the process described in application controls of this manual for set up external static pressure.

NOTE
Supply air CFM will follow the solid line fan curve shown in the above graph if there is any change in the external
static pressure.
Supply air volume for medium and low fan speed tap is also set by remote controller. It will follow the dotted line
fan curve in the graph.
