It is recommended to clean the coil at least at the beginning of each
cooling season or when necessary; turn the unit off first.
• Use a vacuum cleaner or a long-bristle brush to avoid damage to
the coil fins.

must be avoided. Use of these substances will cause serious
damage to the panels and electric parts.
