COMPLIANCE

Page: 3
INSTALLATION
Remove all the packaging materials and tape, as well as any protective plastic from
the machine. Clean off any glue residue left over from the protective plastic or tape
using methylated spirit.
Place the warmer on a firm, level surface in the required position. As a precaution, it
is recommended that all non-metal bench top surfaces be protected from heat with
some form of insulation. A piece of masonite, sheet metal, laminate or similar
material would be sufficient for this task.
Install the feet if required, and adjust the feet individually to ensure the unit is level.
Take a moment to inspect the unit to make sure that it is undamaged as a result of
any freight it may have been through. Familiarise yourself with the functioning of
the switches. Turn all of the switches on and off a couple of times to ensure you
are comfortable with their operation.
Before connecting the Pie Warmer to the power supply, ensure that the thermostat,
the light switch and the main On/Off switch are in the "OFF" position.
Plug the pie warmer into a standard, single phase, 10Amp power point.
National Standards exist outlining the positioning, spacing and ventilation
requirements when installing new appliances. These Standards should be
consulted and new equipment should be installed accordingly. In any situation
where specifications allow a distance of less than 100mm we would still
recommend that a well-ventilated air gap of not less than 100mm be maintained. If
the machine is near particularly heat-sensitive materials common sense should be
employed in determining sufficient distancing.
The four shelves packed with this unit are spaced ideally to maximise the amount of
product that can be heated. Should your requirements be lower this unit has been
designed with an option of installing only three of the racks. This allows for the
increased spacing of the racks, which will result in increased visibility of the
product. These increased spacings are also ideal for the heating of covered food
plates.
Always ensure the power cable is not in contact with hot parts of the Pie Warmer
when in use, and have any damaged power cord replaced immediately.
We recommend the use of an RCD (Residual Current Device) rated at not less than
30mA for circuit protection when using these units. Note that if one RCD is used to
protect multiple socket outlets, the RCD shall be appropriately rated so as to allow up
to 30mA from these machines alone.

Page: 4
OPERATION
Turn the ON/OFF switch to the ON position to turn on the unit. It should lock in the
on position and illuminate the green pilot light above the ON/OFF switch.
The pie warmer is thermostatically controlled. Rotate the thermostat knob to select
the desired operating temperature, usually about 85-90°C for pies and sausage
rolls. The thermostat will then cycle on and off to maintain the set temperature. The
pilot light will also cycle on and off, indicating when the warmer is being heated and
when the set temperature has been reached.
It is recommended that the pie warmer be pre-heated before placing food inside.
As a guide, it is usually best to pre-heat the pie warmer for at least 20 minutes.
Please note that the warmer should not be operated without the crumb tray in
position.
It should be emphasised that these units are designed as food warmers. As such,
they are designed for use with freshly baked or refrigerated product.
While it is outside the scope of the design of these units to use them with frozen
product it is highly recommended that, if frozen product is being used, the product
be thawed before being put in the Pie Warmer. If frozen product is placed in these
units significant time should be added to the preparation in order to produce the
desired serving temperature.
Overall, the general conditions of the Australia New Zealand Food Standards Code
should be met. At the time of writing these instructions, this standard states that
food must be served below 5°C or above 60°C.
These model pie warmers have the added feature of an interior light. The light is
controlled separately by a switch on the control panel and is simply switched on as
desired. The interior light bulb can be changed in the following manner;
Access is gained to the light bulb by removing the cover of the light fitting on the
centre of the ceiling. A Phillips head screwdriver will be required.
Once the cover has been removed, the light bulb can be removed by unscrewing
it in an anti-clockwise direction.
It is also possible to place a small dish of water in the crumb tray or on one of the
shelves to act as a humidity tray. The heated water vapour will assist in keeping
the pies moist, which will prolong the product life. With the humidity tray in use
product should last for 4 - 4½ hours before becoming dry and hard.
Safety Note: When opening and closing the glass doors grip the knob with
your fingertips and gently slide the doors. Do not use excessive force and
avoid touching the glass whilst gripping the knob. Insulating gloves should
be worn if these units are being operated at high temperatures (>110°C).

Page: 5
A GUIDE TO THE HEATING OF PIES
These units are best utilised for maintaining and displaying freshly cooked Pies,
Pasties and Sausage Rolls. Best results will be achieved with freshly baked pies
being placed into the pre-heated cabinet.
As most Pies sold now are pre-cooked and delivered either frozen or at room
temperature the above circumstances are somewhat uncommon.
Approximate times for products to reach serving temperature when thawed (room
temperature) foods are placed in a pre-heated unit are as follows
Meat Pies........... 45-60 mins Sausage Rolls...........25-35 mins
Party Pies .......... 25-30 mins Pasties/Pockets........20-30 mins
It is highly recommended that, if frozen pies are being used, the pies be thawed
before being put in the Pie Warmer. If frozen product is heated in these units add
at least 1½ hours to the preparation time.
Use of high temperatures to speed up the heating and preparation of frozen pies
has several drawbacks;
Frozen Pies are precooked (usually), and placing pre-cooked pies into a Pie
Warmer at 200C will additionally cook the pie. By the time the pie is at serving
temperature in the centre the crust and meat has been over-cooked. This
means that the pie you serve will be dry and hard and not appreciated by your
customers.
The external surfaces of the Pie Warmer will get exceedingly hot and present a
greater hazard to unwary staff or customers.
The extended cooking times for frozen pies will reduce the overall production
capability of the Pie Warmer in that the daily quantity of pies that are able to be
prepared will be reduced.
Element and component life will be reduced compared to running the unit at 90-
100C.
Power consumption of the unit will increase, thereby costing more in electricity
rates.

Page: 6
PRODUCT PLACEMENT
Due to the heat emission from the element the hottest shelves in the Pie warmer
will be the bottom shelves. When new product is placed in the unit throughout the
day it is recommended that these shelves be utilised to prepare the food more
quickly.
If the unit is fully loaded it is desirable to have the tightest packed or most crowded
shelf of products on the top shelves, as the tightly packed product can restrict the
heat from rising to the food above. Restricting the heat convection in this manner
will extend the times required to heat the rest of the product to serving
temperatures.

SAFETY 
GENERAL SAFETY
This machine contains no user-serviceable parts. Roband Australia, one of our
agents, or a similarly qualified person(s) should carry out any and all repairs.
Steel cutting processes such as those used in the construction of this machine
may result in sharp edges. Whilst any such edges are removed to the best of
our ability it is always wise to take care when contacting any edge.
Do not remove any cover panels that may be on the machine.
Replace any damaged supply cord immediately.
This unit can get very hot. Ensure everyone is aware that the machine is
operating and take care to avoid contact with hot surfaces. If operating at
thermostat settings above 110°C provide and use heat-insulating gloves when
opening doors.
SAFETY GLASS
The Toughened Safety Glass used in the Roband®Pie Warmers is about 5 times
stronger than normal glass. In addition to this strength the toughened glass is able
to handle high temperatures and it is designed to shatter into small, relatively
harmless pieces in the event of breakage. These glass pieces can be collected
carefully by hand without resulting in lacerations.
This type of glass has a rather unusual property as a direct result of its toughened
nature. When the glass takes an impact that does not immediately shatter the
piece, it “stores” that stress in the glass layers. This stress “storage” is invisible and
unable to be measured, but it is there nonetheless.
The storing of a stress is only temporary. If the glass suffers a sufficient impact and
the stress is stored, it will one day be released. There is no way to measure when
this release will occur, it could be after a few minutes, or it could be years later.
When the stored stress is released the glass will spontaneously shatter. This could
occur at any time, even when the machine is off and nobody is near it.
On extremely rare occasions a glass door will “explode”. This is a rare but entirely
normal property of the glass, and although pieces of shattered glass may travel
several metres, if they do contact bare skin they should not cause injury (even if
you are directly in front of the explosion). It is important that any contaminated
product be thrown away.
The alternative to such safety glass is to have glass that can be very dangerous
when broken, or worse, could chip off and fall onto the food within (without being
noticed). It is the opinion of Roband Australia that Toughened glass is superior to
both “Clear Float” and “Ceramic” glass with regards to function and safety. If glass
doors are a concern a set of Stainless steel doors may be purchased as an
alternative (contact your supplier).

CLEANING, CARE & MAINTENANCE
Attention to regular care and maintenance will ensure long and trouble free
operation of your toaster. Although scheduled servicing is not required we do
recommend you adopt a program of regular maintenance to ensure that the
machine is clean and functional and to avoid inadvertently damaging the unit.
Ensure the power is off and the Pie Warmer is cool before attempting to clean any
part of the machine.
Wipe the surfaces down with warm soapy water using a damp sponge or cloth.
Do not immerse the unit in water or allow the ingress of water into the ventilation
holes or controls. This unit is not suitable for cleaning with the aid of a water jet or
similar system.
Daily cleaning of the crumb tray is essential. The crumb tray may be removed by
sliding it out from the unit. The crumb tray should be emptied and washed with
warm soapy water.
The glass should be cleaned daily with an appropriate cleaning agent for both
aesthetic and hygienic reasons.
Always ensure the power cable is not in contact with hot parts of the Pie Warmer
when in use, and have any damaged power cord replaced immediately.
Note: If foil is used to cover the trays the foil should be replaced daily, and
ventilation holes must be made every few centimetres to allow the food to be
heated evenly throughout the unit.
Note: Some cleaning agents can damage stainless steel, usually through prolonged
use. For this reason we recommend cleaning with soapy water. Any damage to the
unit through the use of harsh or improper cleaning agents is entirely the fault of the
user.
CAUTION: Handle glass with care when cleaning.
CAUTION: Although every care is taken during manufacture to remove all sharp
edges, care should be taken when cleaning and handling the Pie Warmer to avoid
injury.

APPENDIX A
RESIDUAL CURRENT DEVICES (RCD’S)
Also known as Earth Leakage Protection systems an RCD is a protective device
that automatically disconnects the live conductors of a circuit when an earth
leakage current reaches a predetermined value.
Australian and International Standards detail when and where RCD’s are to be
used in electrical installations, but common practice in many countries is to use a
30mA RCD in general commercial applications. This is typically done because
30mA RCD’s are readily available and are used in domestic installations.
For Commercial installations, and for socket-outlets providing power to commercial
heating equipment (Toasters, Bains Marie, Grillers), 30mA RCD’s are typically
unsuitable unless they are protecting only one device. Higher rated RCD’s should
be considered if protecting multiple socket-outlets, giving appropriate consideration
to the type of equipment being protected.
AS/NZS3000 2.5.2 gives the following warnings that should have been taken into
consideration when an RCD circuit was installed.
To avoid unwanted tripping due to leakage currents and transient
disturbances, care should be taken to ensure that the sum of the leakage
currents of electrical equipment on the load side of an RCD is less than
1/3 of its rated residual current.
To avoid excessive leakage current causing unwanted tripping where
socket-outlets are protected by one RCD having a rated residual current
not greater than 30mA, consideration should be given to the number of
socket-outlets protected and the nature of electrical equipment likely to
be connected to the socket-outlets.
Tubular elements (such as those used in this unit) reaching temperatures greater
than 110°C are subject to moisture absorption and therefore earth leakage current
generation. Should the installation and use of this unit trip an RCD the unit will
need to be run on a circuit without an RCD for approximately 30-60 minutes, after
which time the elements should have dried out and the machine should function
normally. If you are unable to locate a circuit without an RCD please contact your
supplier or contact Roband or our Agent for alternative suggestions.
