9.0 Cleaning and Maintenance
Make sure that the dry bath and block are cool and the power cord is disconnected before performing any cleaning or maintenance.
Repair or maintenance should only be performed by an authorized service technician.
The dry bath may be cleaned with a moist cloth containing a mild soap solution. Do not immerse the dry bath in water or any liquid.
Spills: In the event liquid is accidentally spilled into the block area, disconnect the plug from the outlet and turn the unit upside down
to minimize liquid contact with the internal components. Allow the unit to dry. Have a qualified service technician clean the unit and
replace any damaged parts.
