Cautions during maintenance:
a.
Unplug the CFD-50 before cleaning. Wipe both inner and outer surfaces using a soft cloth dipped with neutral
non-corrosive cleaning agent. Do not use any brushes, acidic or alkali detergents. Use a dry cloth to wipe clean
surfaces. Do not use any organic solvents, hot water, detergents, or other harmful substances for cleaning
b.
in order to avoid water leakage to electric component and damage to the exterior, do not pressure-wash or use
any hard scrub to clean the CFD-50.
c.
Use warm water to scrub and clean the door gasket weekly in order to maintain its flexibility and elasticity.
Rub the door gasket with talcum powder to prolong its use.
d.
Before decommissioning the CFD-50, pull the power supply plug out, clean the inside thoroughly, use a dry
cloth to wipe the interior and leave the door open for 2 to 3 days until the inside is completely dry.
