Operation
WARNIN
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 equipment.
Do NOT place anything heavier than 2 kg ( .1Ibs) on to the display surface.
The equipment will only maintain the temperature of products that have initially been cooked, prior to
display. Ensure that food is transferred to the display area immediately after cooking in appropriate
containers or packaging.
Ensure that temperatures of the displayed products are checked and recorded on a regular basis, in
accordance with local regulations.
The temperature of the unit is displayed by the controller and is for indication of operating temperature
only. Do NOT use this as a reference to core temperature of foods on display; regular temperature probing
of the product 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 Flexeserve® appointed engineer.
To view the set temperature of the unit, press the ‘temperature’ button for half a second, and then release.
To change the temperature of the unit, press and hold the ‘temperature’ button and press the arrow
buttons to increase (▲) or decrease (▼) the temperature. When the ‘temperature’ button is released, the
new value is stored. 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.
Flexeserve Hub® is manufactured to comply with health and safety regulations. You must operate the
equipment properly using only calibrated temperature probes to ensure food is thoroughly cooked to the
safe standards according to local regulations.

Display and Merchandising
Different products require varying display times according to their core temperature. These must be
considered to ensure the best quality and safe temperature for consumption is achieved. The Alan Nuttall
Partnership Ltd does not accept responsibility for variances or losses of quality that occur due to product
differences.
All items placed in Flexeserve Hub® should be in the correct packaging/containers, in line with in-store
procedures and best practice. Remove products in damaged packaging from the equipment and clean as
soon as possible.
The door handle must be used at all times when opening and closing the door. Ensure that the door is
fully closed once the products have entered the display area.
Product Probing
INFORMATION
Legal requirements dictate all products displayed for an extended period within any
heated display area should be periodically probed throughout trading to ensure the
core temperature of the product is above the legal holding temperature of the local
authority. Refer to in-house operations manual for product probing instructions.
It is beneficial to enter the product into the holding unit as hot as possible for that particular food product
to maximise shelf-life at the safe temperature.
The equipment is not designed to increase product temperature; the products gradually fall and regulate
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 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, reduced and
disposed of, in accordance with company and food safety standards.
The Alan Nuttall Partnership Ltd does not take responsibility for variances or losses of quality that may
occur due to product differences.
Recording Product Temperatures
The core temperature of the products should be periodically probed and recorded according to local
authority guidelines.
