cooling season or when necessary; turn the unit off first.

the coil fins.

• Damage to the fins may cause reduced coil efficiency resulting in
increased running costs. Use of flames, liquid or aerosol solvents
must be avoided. Use of these substances will cause serious
damage to the panels and electric parts.
