These are the original version controlled Henny Penny instructions for Pressure Fryer
Gas (PFG) model 600 (PFG 600). This manual is available on the Henny Penny
Public website (www.hennypenny.com). Read these instructions completely prior to
installation and operation of this appliance to ensure compliance to all required
installation, operation and safety standards. Read and obey all safety messages to
avoid damage to the appliance and personal injury.

This appliance is intended for commercial use in kitchens of restaurants, bakeries,
hospitals, etc. but not for the continuous mass production of food such as in a factory
setting. During use the units airborne A-weighted emission sound pressure is below
70 db(A). All repairs must be performed by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
Always use strain relief. The provided power cord must be installed with a strain relief
in a way that if the strain relief fails, wires L1, L2, L3 and N must draw taunt and fail
first. If the supplied power cord or an existing one becomes damaged, do not use it;
rather, replace it with a known good power cord. The power cord must be replaced by
the manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
Proper daily, weekly, monthly, quarterly and yearly maintenance must be performed
on this appliance to ensure safe and continuous operation. This appliance must never
be cleaned with a water jet or steam cleaning tool. Cleaning brushes are shipped with
the appliance and proper cleaning instructions are included in this manual.
Proper maintenance also increases the usable life of the appliance and oil, which
reduces lifetime operating costs. Additionally, old oil increases the possibility of surge
boiling and fire due to the reduced flash point of the oil. The oil temperature must
never exceed 450⁰ F (230⁰ C).
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 use of the appliance by a

person responsible for their safety. Children should be supervised to ensure that they
do not play with the appliance.
This appliance is not intended to be operated by means of an external timer or a
separate remote control system.
This appliance must be installed in accordance with the manufacturer’s instructions
and the regulations in force and only used in suitably ventilated location. Read the
instructions fully before installing or using the appliance.
This appliance must be installed with suitable ventilation in accordance with the
manufacturer’s instructions and the regulations in force to prevent the occurrence of
unacceptable concentrations of substances harmful to health. Proper air flow is
