1.5.3. Power
If the line voltage for your LBB Series oven varies more than 10% from the oven voltage rating,
electrical components such as relays and temperature controls may operate erratically.
If the line voltage is lower than the oven voltage rating, heat-up time may be significantly
longer and motors may overload or run hot
If the line voltage is higher than the nameplate rating, motors may run hot and draw excessive
amperage
*
LBB1-69 and larger models have reinforced shelves. Standard duty (50 Lbs. maximum) shelves are also
available.
Warning!
Do not exceed a total of 400 Lbs. (181 Kg) for stacked LBB1-69 ovens.
