• Any repairs or maintenance must only be carried out on
the unit by a suitably qualified engineer. Before opening
and servicing the unit the authorized engineer must be in
possession of a copy of the manufacturer’s service manual
and must follow the safety information contained within it to
ensure all hazards are minimized.
• The refrigerant system should not be perforated
or punctured.
• Do not cover or restrict the airflow from the outlet or
inlet grills.
• Keep the filters clean . Under normal conditions , filters
should only need cleaning once every three weeks
( approximately ) . Since the filters remove airborne
particles , more frequent cleaning maybe necessary ,
depending on the air quality.
