3. Weekly Maintenance
Clean Drain
• Each cooking compartment is equipped with a drain screen
• Always operate steamer with screen(s) in place
• Screen(s) prevents large food particles from entering and blocking drain line
• Blockage of drain line can cause pressure buildup in compartment(s) resulting in steam leaks
around door gasket(s)
• Drain line blockage reduces convection action of steam in compartment(s) and reduces
performance
a) Inspect drain screen and drain line for blockage
b) Rotate drain screen 90 degrees to inspect drain opening
c) Clean opening and restore screen to its operating position
d) Clean drain with a USDA approved drain cleaner
e) Follow the instructions of the drain cleaner manufacturer
