Periodic inspection
• After being used for a long period of time, the parts
may deteriorate or malfunction, or the drainage may
worsen, due to heat, moisture, dust, or general usage.
• In addition to the maintenance, it is recommended that
you have a inspection (charges apply) performed by
the dealer where you purchased the unit, etc.
CAUTION
4-way air discharge cassette type
• Perform high-pressure cleaning for the heat
exchanger.
If commercially available detergent (strong alkaline or
acid cleaning agent) is used, the surface treatment of
the heat exchanger will deteriorate, which may
degrade the self cleaning performance.
For details, contact our sales department or the dealer
where you purchased the unit.
