line.

• Destroy the carton, plastic bag, and other packing materials after the appliance is unpacked. Children
might use them for play. Cartons covered with rugs, bedspreads, or plastic sheets can become airtight
chambers.
• Never attempt to operate this appliance if it is damaged, malfunctioning, partially disassembled, or has
missing or broken parts, including a damaged power supply line.
• Adhere to all industry recommended safety procedures including the use of long-sleeved gloves and
safety glasses.

Operation
• Repair or immediately replace all power supply lines that have become frayed or otherwise damaged. Do
not use a power supply line that shows cracks or abrasion damage along its length or at either end.
• If you detect a strange sound, a chemical or burning smell, or smoke coming from the appliance, unplug

etc.), gasoline, chemicals and other flammable vapors and liquids.
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning the use of the appliance by a person responsible for their safety.
• If the electrical supply line is damaged, it must only be replaced by the manufacturer or its service agent

for two weeks or more. HYDROGEN GAS IS EXPLOSIVE. If the hot-water system has not been used for
such a period, before using the appliance turn on all hot water faucets and let the water flow from each
for several minutes. This will release any accumulated hydrogen gas. As the gas is flammable, do not
smoke or use an open flame during this time.

- Locate sharp items so that they are not likely to damage the door seal.
