Step 4 Insert the positive pressure tube of the differential pressure gauge into the unit
through the cable hole for about 30 mm.

positive pressure tube
NO TE
The cross section of the pressure tubes must be perpendicular to the wind direction.
Step 5 Start the unit, set the indoor fan speed to the maximum value, and read the
pressures measured at the positive and negative pressure points.
NO TE
Choose Maint > Diagnostic Mode > Enter and set the indoor fan speed to the maximum
value.
Step 6 Tap Start on the home screen. Ensure that the unit is running normally without
any alarms.
Step 7 Log in to the WebUI as user admin, choose Settings > System Settings > System
Control > Advanced, and set Static pressure.
Step 8 Choose Running > Status Summary and view the value of air volume.
NO TE
● Static pressure setting = Pressure measured at the positive pressure point – Pressure
measured at the negative pressure point.
● User operator can access customer and delivery parameters. The parameters on the
Advanced menu are delivery parameters. User admin can access customer, delivery,
maintenance, and R&D parameters. The parameters on the Advanced menu are R&D
parameters.
● To prevent the effect of misoperations on the system, log in as user operator before
modifying parameters. Confirm with Huawei technical support before modifying
parameters which cannot be modified by user operator. Otherwise, Huawei will not be
liable for any consequences of the modification performed by the user.
● Only certified professionals are allowed to modify advanced parameters of the unit.
Unauthorized modifications can result in unit malfunction and even damage.
