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

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.
