COMMISSIONING THE HEAT PUMP AIR CURTAIN
Ensure that the electrical supply to both the Mitsubishi Electric Outdoor Unit and
the local electrical supply to the Air Curtain are switched off.
Air Curtain Checks
Check that the components inside the air curtain are as shown in the picture below.
Check that the thermal overheat cut-out switch has not ‘tripped’. Push down on the red
button on the top of the thermal overheat switch - if it has tripped it will click back on.
A Mitsubishi Electric Interface PCB is located within the Thermoscreens Air Curtain to
provide communication between the Mitsubishi Electric Outdoor Unit and the Air Curtain
Indoor Unit.
The Interface PCB on its mounting plate 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. For easier withdrawal of the pcb the filter
indicator connection may be temporarily removed.
Now go to either “BMS Control” or “Manual Room Control” to continue with the
Commissioning of the Air Curtain.
