Maintenance - Mitsubishi Electric MJ-E20TX-H Instruction Manual

Maintenance

Do not use detergents, cleaning agents for heat exchange equipment, abrasive powders, chemically treated dusters,
gasoline, benzene, thinners or other solvents, as they can damage the unit or the water tank, which may result in
leakage.
Cleaning
Water tank · Main unit
Wipe with a soft cloth.
Floating element
Do not remove or dismantle.
The unit draws in dust present in the air, and
¡
this may cause the tank to gradually
become dirty. If the dirt does not come off
easily, wash with cold or warm water, then
wipe with a soft, dry cloth.
Mildew may form in the tank unless kept
¡
clean.
Once every two weeks
Pre-filter
Debris clogging the pre-filter reduces the

once every 2 weeks.
