locations.
GENERAL SAFETY CONSIDERATIONS
Note: Failure to follow the guidelines and instructions in this manual may create a protection
impairment by disabling or interfering with the unit’s safety features. This can result in injury
or death.
Before you use your oven read this entire manual carefully to understand how to install, operate,
and maintain the oven in a safe manner. Keep this manual available for use by all oven operators.
Ensure that all operators are given appropriate training before the oven begins service.
Your oven and its recommended accessories have been designed and tested to meet strict safety
requirements. For continued safe operation of your oven, always follow basic safety precautions
including:
Follow any local or regional ordinances in your area regarding the use of this unit.
Only use the oven for its intended range of applications.
Use only approved accessories. Do not modify system components. Any alterations or
modifications to your oven may be dangerous and will void your warranty.
Always hardwire the unit power feed to a protective earth-grounded electrical source that

knobs and controls may conduct electricity and cause serious injury.
Avoid damaging the power feed. Do not bend it excessively, step on it, place heavy objects
on it. A damaged power feed can easily become a shock or fire hazard. Never use a power
feed after it has been damaged.
Position the equipment so the end-user can quickly and easily disconnect or uncouple the
power feed in the event of an emergency.
