The Hatco GRSDSI warmers are designed for maximum durability and performance with minimum maintenance. To avoid
injury, turn the master power switch off, unplug the unit from
power source and allow to cool before performing any maintenance.
CLEANING
To preserve the finish of your unit, it is recommended that the
exterior and interior surfaces be wiped daily with a soft damp
cloth. Stubborn stains may be removed with a NON-ABRA SIVE, MILD CLEANER.
Use only NON-ABRASIVE CLEANERS. Abrasive
cleaners will scratch the hard-lube teflon finish of the
shelves, marring its appearance, making it susceptible to
soil accumulation and reducing the performance.
Clean the glass sides using a common glass cleaner.
To remove the glass sides, turn the unit off and wait until it is
cool. Place one hand on the inside against the glass and the
other hand on the outside against the glass. Lift the glass
