SERVICING THE AIR CURTAIN
Vacuum Clean the Air Inlet Grilles / Filters
(Fortnightly, or when the Filter Dirty Indicator shows PERMANENT RED)
With the air curtain switched OFF, a vacuum cleaner with an
extension tube and brush attachment at its end should be used
to clean the face of the air inlet grilles. This is important to
minimise the build-up of dust and lint on the air filters inside the
inlet grilles which will affect the performance of the air curtain.
This is a simple service task that can be carried out by the
Cleaner or Janitor on a weekly basis from floor level without
having to access the air curtain at high level. This should be
done weekly as a regular service task and/or when the Filter
Dirty Indicator shows permanent red.
ONLY if the Filter Dirty Indicator shows PERMANENT RED
Reset the Filter Dirty Indicator after cleaning by a quick
press of the Reset Button.
NB
.The filter dirty interval feature on the Mitsubishi Electric
remote controller is not available.
Servicing the Air Curtain
(suggest every 6 Months, or if the Filter Dirty Indicator shows FLASHING RED)
Before servicing, maintaining or repairing the Air Curtain always isolate the local
electrical supply to the Air Curtain and the electrical supply to the Mitsubishi
Electric Outdoor Unit.
Note: All servicing, maintenance and repairs to the air curtain must be carried out by an
approved Service Agent. Keep any loose fixings for re-assembly.
Remove the plastic end caps at each end of the unit by pulling off to
the side as shown in the picture.
Remove each air inlet grille with its air filter by unfastening the
quarter-turn Philips Head fastener at the bottom corner of the
grille. Use a Philips No.1 screwdriver to access the screw via
the elongated hole at the bottom corner of each grille and turn
anti-clockwise to remove (see picture).
