REPLACEMENT OF PARTS
For replacement parts, users and service personnel are
referred to US Range Cuisine Series Heavy-Duty Ranges and
Attachments parts list. This section of the service manual
deals only with the replacement of parts on heavy duty
cooking equipment.
WARNING:
Before servicing any cooking appliance be certain to
SHUT OFF the gas supply at the shut-off valve and the
electrical supply at the main disconnect. On completion of
any servicing work, test for gas leaks before returning the
equipment into service. Regarding electrical work, always
shut off the electrical supply at the mains and secure the
breaker panel with a lock before doing electrical work. Do
not service electrical equipment until the power is securely
locked off.
