Safety Requirements RTCSmp Built-In Temperature Controlled Hold-Line
o Do not place credit cards, phone cards, tapes, or any objects sensitive to magnetism on the cooking
surface.
o Do not place plastic vessels and aluminum objects such as aluminum foil on the glass-top.
Persons with a cardiac pacemaker should consult their doctor whether they are safe near an induction unit.
If the power cord is damaged, have it replaced immediately by an approved service technician.
Ensure liquid cannot enter into the induction unit. Do not let water or food overflow the cooking area. Do not
use hoses to clean or power wash the induction unit or its vicinity.
The induction unit has an internal air-cooling system. Do not block the air intake and exhaust openings with
objects such as cleaning cloths or containers. Any obstruction to the air intake and exhaust could cause the
unit to overheat and to switch off.
Switch the unit OFF if you take the cookware away for a while. This will prevent the heating process to start
automatically and unintentionally when a pan is placed back on the heating area. If any person needs to use
the induction unit, he/she will have to turn the unit ON intentionally.
A dirty air filter blocks the fresh air inlet. The Air Inlet Filter should be cleaned at least once a week (dish-
washer safe) or as often as necessary. Wipe the filter dry before putting it back into the unit.
Remove immediately any food residuals from the glass-top.
Use only induction suitable cookware with proper size and made of proper material. The induction suitable
cookware should also be in good condition without any uneven, arched or partially detached bottoms.
