FusionCol8000-E400 Modular Indirect Evaporative
Cooling System
User Manual
measured by other precise temperature measurement units at the return air
monitoring point is 20°C but the return air temperature detected by the unit is
22°C, the sensor has an error of 2°C. In this case, you can set the return air
temperature calibration value to –2°C.
Procedure
Step 1 Choose Maint > Sensor Calibration on the home screen.
Step 2 Fill the calibration value based on the measured error.

10.2.12 How Do I Check the Display of Normal Air Volume?
Prerequisites
●
Procedure
Step 1 Tap Shutdown on the home screen of the display module.
Step 2 Remove the sheet metal from the condensate drainpipe. Route the negative
pressure tube of the differential pressure gauge along the condensate drainpipe
and then into the unit. Secure the negative pressure tube to the water pump
drainpipe. The cross section of the pressure tubes must be perpendicular to the
wind direction. The positive pressure tube is placed outside the unit and connected
to the atmosphere.
Step 3 Start the unit, set the indoor fan speed to the maximum value, and read the
pressure measured by the differential pressure gauge at the negative pressure
point outside the unit.
Step 4 Remove the pressure tubes, install the sheet metal, and seal it with sealant.
Step 5 Drill holes on the cross section of the pipe wall 4.5 m away from the air vent.
Connect the pressure inlets of the four static pressure holes to form a static
pressure ring, connect the positive pressure tube of the differential pressure gauge
to the static pressure ring, and connect the other end to the atmosphere.
Step 6 Start the unit, set the indoor fan speed to the maximum value, and read the
pressure measured at the positive pressure point.

Tool: differential pressure gauge (purchased onsite)
NO TE
Exercise caution because the device is still energized after it is shut down on the screen of
the display module.
NO TE
If the distance for drilling holes is not 4.5 m, adjust it to be close to 4.5 m based on the
actual installation scenario.
