IV. SERVICE AND REPAIR
A. WARNINGS
: Disconnect the power supply
to the appliance before servicing.
: Units provided with casters
have a restraint to limit the movement of the
broiler. If this restraint is disconnected during
servicing it must be reconnected after the
appliance has been returned to its original
installed position.

Proper clearances must be maintained during
servicing.

responsible for repair or servicing of commercial
food preparation equipment, who are experienced
in such work, familiar with all precautions required,
and have complied with all requirements of state and
