and maintained properly, helping your new investment to perform well for you now,
and to continue performing in the many years to come.

GENERAL PRECAUTIONS

This machine must only be operated by qualified person(s) who are fully versed in
the operating and safety instructions described in this manual. Servicepersons
should be instructed to familiarise themselves with any and all safety instructions
described in this manual prior to commencement of any maintenance or service.

In the case of new personnel, training is to be provided in advance. These
machines should not be operated by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience or knowledge, unless
they have been given supervision or instruction concerning the safe use of the
appliance by a person responsible for their safety.

These machines are heating units, and as with any commercial heating
unit the surfaces will get hot. Always be careful when near an operating
coffee warmer, and ensure that any risk to unwary customers or staff is
minimised with additional signage if necessary. Due to the obvious heat
hazard Roband recommends that these units be kept out of reach of
children.

The performance of this unit cannot be guaranteed for operational use
outside its design parameters.

The machine should be disconnected from all power and allowed to cool
before cleaning.

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 using
methylated spirit.

Place the Coffee Warmer Unit on a firm, level surface in the required position.
Before connecting the unit to the power supply ensure that all the controls are in the
“OFF” position.

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.

Plug the boiling hot plate into a standard, single phase, 10Amp power point.

Page: 4

OPERATION

The two green rocker switches on the left and right side of the front activate the
coffee warmer unit. Each switch controls the heating of one of the warming plates.
When the on position is selected the switch will glow and the element will heat up.
Turn one or both switches on as required. Place full coffee pots on the warming
plates to keep coffee at a constant temperature.

These units are designed to maintain the coffee temperature at approximately 85 –
90 C.

This machine does not rely on a temperature controller, which means the fluid
temperature will be dependent on the volume in the jug. It is important to keep an
eye on the liquid level of the tea/coffee. As the coffee fluid level falls to a ¼ full the
pot should be refilled.

If a pot is a ¼ full and is left on the unit the coffee will get too hot and may get hot
enough to boil. This will ruin the coffee. If your coffee usage is not high, a full pot
should not be used. A full pot that is not being drawn off will slowly lose heat and

will only maintain the temperature at approximately 50C.

A Quick Note on Serving Coffee

The best quality coffee is served within the first 15 minutes of being placed on the
coffee warmer. Coffee that is kept for over half an hour will stew, becoming over­cooked and bitter.

Based on cost, if 4 or 5 cups are served from one jug the rest could be safely
thrown away knowing that you have well and truly covered the costs of making the
jug of coffee.

Example: If a jug holds 20 cups of coffee and each cup costs about 20 cents to
make, and 4 cups are sold at $3.00 per cup, then,

Profit = Revenue - Costs
= 4 cups x $3.00 – 20 cups x $0.20
= $12.00 - $4.00
= $8.00 profit per jug even if 16 cups are thrown away.
Based on the above example a minimum of only 2 cups of coffee need to be served

from a jug to cover the costs of making a jug of coffee.
(This example is for illustrative purposes only. Costs will vary depending upon the

individual costs of a business).

 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. Any
repair person(s) should be instructed to read the Safety warnings within this manual
before commencing work on these units.

Steel cutting processes such as those used in the construction of this
machine 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.

Particular care should be taken to avoid contact with any steel edge, and warnings
should be given in regards to the danger of such contact to any repair or
maintenance person(s) prior to commencement of any servicing.

Do not remove any cover panels that may be on the machine.
This unit can get very hot. Ensure everyone is aware that the machine is operating

and take care to avoid contact with hot surfaces.

Always ensure the power cable is not in contact with hot parts of the
machine when in use. Ensure that any damaged power cord is replaced
before further use.

Keep this unit out of reach of children.

Electricity is dangerous, and should only be handled by qualified professionals. It’s your
life – Don’t risk it.

CLEANING, CARE & MAINTENANCE

Attention to regular care and maintenance will ensure long and trouble free
operation of your coffee warmer. Although scheduled servicing is not required we
do recommend you adopt a program of regular maintenance to ensure that the hot
plate is clean and functional and to avoid inadvertently damaging the unit.

Daily cleaning should be considered mandatory for all cooking equipment. In order
to ensure the cooking plates are cleaned properly and to avoid damage to the unit,
the instructions below should be followed.

 Clean the appliance with a damp cloth.
 Wipe up any spilled beverage as soon as possible.
 The Plate should be cleaned at the end of each day using hot soapy water, with

the machine turned OFF but while the plates are still warm.

 NEVER put cold water on the warm or hot plates. This may cause the plate to

buckle due to the sudden change in temperature.

 Wipe down the remainder of the machine with a cloth or sponge that is only

DAMP with soapy hot water, taking care to avoid water entering any part of the

unit.

 Do not clean these units with the use of a water jet.

CAUTION: Although every care is taken during manufacture to remove all

sharp edges, care should be taken when cleaning 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.
