Operation
WARNING
Only if the operator has been trained and is skilled in the operation of the equipment
covered in this guide should this information be followed.
Do NOT attempt to cook products in the Flexeserve Zone® shelves.
Do NOT place cooking vessels into the Flexeserve Zone®.
Do NOT place anything greater than 20 kg onto the display surfaces.
The equipment will only hot-hold products that have initially been cooked, prior to display. Ensure that
food is transferred to the display area immediately after cooking in appropriate display containers or
packaging.
Ensure that temperatures of the displayed products are checked and recorded on a regular basis, in
accordance with local procedures.
The temperature of each zone is displayed by the appropriate zone controller and is for indication only. Do
NOT use this as a reference; regular probing of the product temperatures is to be performed.
The minimum and maximum set-point values have been pre-set in the factory to prevent the equipment
holding temperatures from being adjusted beyond legal and safety limits. These can only be adjusted by a
Nuttall appointed engineer.
To view the temperature of the unit, press the ‘SET’ button for half a second. To change the temperature,
press and hold the ‘SET’ button and, at the same time, press the arrow buttons to increase (▲) or decrease
(▼) the temperature. After the temperature has been set, the display will revert back to the operating
temperature, which will rise or fall as it reaches the set temperature.
The Alan Nuttall Partnership Ltd complies with health regulations, and are tested and certified to NSF
standards. You must operate the equipment properly using only calibrated thermometers to ensure
produce is thoroughly cooked to safety standards.

OPERATION MANUAL
IBS 40002210 Page | 19 V13 (January 2019)
Display and Merchandising
Different products require varying display times. These must be considered to ensure the best quality and
temperature for consumption is achieved. The Alan Nuttall Partnership Ltd does not accept responsibility
for variances or loss of quality that may occur due to product differences.
All items placed in the unit should be in the correct packaging/containers, in line with in-store procedures
and best practice.
To ensure good heat conduction into the product, only place a single layer of products on the display area.
Remove products in damaged packaging from the equipment and clean as soon as possible.
Product Probing
INFORMATION
Legal requirements dictate all products displayed for an extended period within any
heated display area should be periodically probed throughout the day’s trading to ensure
the core temperature of the product is above the legal holding temperature of 63°C.
Refer to in-house operations manual for product probing instructions.
It is beneficial for the holding time to enter the product into the hot-hold unit as hot as possible for that
particular food product.
The equipment is not designed to increase product temperature; the products gradually fall in temperature
throughout the display period to ensure good product quality. It is critical that the entry core temperature
is as high as possible so that the maximum display time is achieved. The product will fall in temperature
during its display time regardless of the entry temperature; therefore a low entry temperature will reduce
display time.
At the end of recommended display times, any unsold products should be removed and disposed of, in
accordance with company and food safety standards.
The Alan Nuttall Partnership Ltd does not take responsibility for variances or loss of quality that may occur
due to product differences.
