6 Cleaning
Wash the inside of the cabinet with a solution of one quart of
warm water and two tablespoons of baking soda.
Wash the outside with a mild detergent such as dishwashing
liquid. Do not use harsh or abrasive cleaners.
When the condenser tubing on the back is dusty, vacuum it clean.
CAUTION! Condensers should be cleaned at least
every six months. In heavy traffic areas, condensers
load with dirt more quickly. Failure to keep the
condenser clean can result in equipment warm-up or
erratic temperatures.
