OPERATION (continued)
Steaming Tips
• Pre-cooked pasta is easily reconstituted and gives
you a hot product without the wetness of the normal
“dip” method.
• Experiment with your products and different
steaming times - a little more or less steam could
enhance the appearance/flavor.
• If you serve melted cheese on sandwiches, steam
is the perfect way to melt cheese.
• A steamed bun (which takes about 10-15 seconds)
says “Hot Sandwich” to your customer.
• Vegetables, rice, and bread products can be recon-
stituted by steaming before serving, which reduces
waste.
• Dinner rolls, muffins, even tortillas can be heated
completely and held without drying out the product.
• Use a low plate or pan when steaming to allow full
steam penetration and shorter cooking times.
• Use the “1 in 20 rule: Push the operate switch for
one second every twenty seconds. This will ensure
that the product gets fully heated without using
excess water or energy.
• Condensation inside the steamer is normal, but
excess moisture indicates too much water is being
used. Use the “1 in 20” rule above and check/
adjust the programming if needed. See the pro-
gramming section of this manual.
• Heat meat and bread products apart from each
other, then combine in a sandwich. This keeps the
meat juices from soaking the bread.
• Clean the top cover gasket as often as possible or
at least once a day with a soft, clean cloth.
• Finish off a special meal with a steamed hand
towel.
Hi-Limit Reset Button

allow sufficient time (about 45 minutes) for the unit to
cool down, remove the cap located on the rear of the
unit (Figure 8) and then fully depress the reset button .
If the unit requires continuous resetting, contact your
Roundup authorized service agency.
