SERVICING THE HEAT PUMP AIR CURTAIN
Vacuum Clean the Air Inlet Grilles / Filters
(Weekly, 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 at the
back of 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.
Reset the Filter Dirty Indicator after cleaning by a quick
press of the Reset Button (even if the indicator has not gone
red).
Servicing the Air Curtain
(suggest every 3 Months, or if the Filter Dirty Indicator shows FLASHING RED)
Always disconnect and isolate the mains electricity supply both at the local
electrical supply to the Air Curtain and at the Mitsubishi Electric Outdoor Unit
before servicing, maintaining or repairing the Air Curtain.
Note: All servicing, maintenance and repairs to the air curtain must be carried out by an
approved Service Agent.
Remove the plastic end caps by pulling
off to the side as shown.
Remove each Air Inlet Grille with its air
filter by unfastening the M4 Pozi Head
screw at the bottom corner of the
grille. Use a Pozi No.1 screwdriver to
access the screw via the elongated
hole at the bottom corners of the grille.
Remove the air filters from the air inlet grilles by gently prizing
them free as shown. Vacuum clean and refit the filters into the
curved air inlet grilles. The filters are very durable but may need to
be replaced after a number of service intervals.
