COMMISSIONING THE AIR CURTAIN
Ensure that the local electrical supply to the Air Curtain and if necessary the
electrical supply to the Mitsubishi Electric City Multi system are switched off.
Air Curtain Checks
Check that the components inside the air curtain are as shown in the picture below. If
the defrost cycle auxiliary heater has been enabled check that the thermal overheat cut-
out switch(s) has not 'tripped'. Press the reset button at the top of the unit (2 on a VRF
HP2000 DXE unit). If the cut-out switch has tripped it will click back on – see picture

PCB fixing
screw location
There is a Mitsubishi Electric Interface PCB located within the left hand end of the
Thermoscreens Air Curtain. This provides control and communication between the
Mitsubishi Electric City Multi system and the Air Curtain Indoor Unit. It is held in place by
a fixing screw located in the left-hand end panel of the air curtain under the left-hand
plastic end cap. Remove the screw and carefully slide the PCB partially out.
