screw. The Filter Indicator Schedule can now be changed from its default setting if
required (see page 15). Replace the bottom access panel, air inlet grilles (with filters)
and plastic end caps (see “To gain access inside the Air Curtain” page 7). Power-up
both the Outdoor Unit and Air Curtain and re-check the operation of the unit

On the Thermoscreens Manual Room Control set the Fan On/Off switch to Off '0' and
the Ambient/Heat switch to Ambient ' ' Fan only. Switch on the electrical power to
the Mitsubishi Electric outdoor unit and the Air Curtain. WARNING! Interface PCB will
have 230 volts on it.
Communication between the Mitsubishi Electric Outdoor Unit and the Air Curtain
commences approximately 30 seconds after power-up. After this time use the Room
Control to switch on the fans. Once the air curtain fans are operating check that they
run at Low (I), Medium (II) and High (III) speeds using the manual 3 speed fan switch
inside the left hand end of the air curtain. Check there is no mechanical noise coming
from the fans and that all fans are working. Select the fan speed appropriate to the
site conditions and leave on this setting.
Using the Manual Room Control set the Ambient/Heat switch to Heat ' ' and the heat
setting switch to Full Heat '
'. Check that the air stream from the discharge warms
up across the whole length of the air curtain after approximately 20 minutes and that
the air stream reaches right down across the doorway with the door open or closed.
Use the Manual Room Control to test the different heat settings. LEDs 1-5 on the
Interface PCB should be lit as follows.
