Installation
Unpacking
Unpack the mixer immediately after receipt. Please inspect the mixer to ensure
no damage and all parts i.e. Bowl, Beater, Whisk & Dough Hook have been
provided. If the machine is found to be damaged, keep all the packaging
material and contact us immediately or contact your source of the equipment.
Never attempt to operate the machine with damaged parts. Report any
deficiencies to the dealer that supplied the machine.
You should receive with your mixer:
- 1 x Stainless Steel Bowl
- 1 x Beater
- 1 x Whisk
- 1 x Dough Hook
If any of the above items were not received with your mixer, please refer to
page 16 for contact details and inform us immediately for replacements.
Before using the mixer, please read this manual thoroughly. Do not proceed
with any installation nor operation if you have any questions or do not
understand anything within this manual. Please see contact details on page 16
for assistance. Carefully unbolt the mixer from the pallet using a wrench
socket.
Location
- Select a location for the machine with a minimum of 0.6m space around the machine for operating, cleaning and servicing.
- Position the machine in its proper working position. The machine must be installed on a flat, solid and dry floor.
- The surface must be able to support a load of 200kgs
- It is recommended that the machine is level from front to back and from side to side. This will ensure the greatest stability.
- The rear ventilation outlet of the mixer must not be blocked
- The mixer should be bolted down into position using all four holes located in the legs.
Electrical Connection
- Before connecting the mixer to an electrical supply, please read the specifications on the rating plate to ensure that they comply with those of the electrical supply. The mixer should be fitted to an isolated electrical supply, capable of supporting an electrical load of 20amps.
- Electrical connection should be made by a qualified service technician who will observe all applicable safety codes. The machine works off 220/240V 50Hz 1 phase supply and comes fitted with a colour-coded three-core cable as follows:
- Brown: Live
- Blue: Neutral
- Green/Yellow: Earth
As the colour of the wires may not correspond to the coloured markings identifying the terminals in your plug, you should proceed as follows:
- The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.
- The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.
- The wire which is coloured green/yellow must be connected to the terminal which is marked with the letter E or coloured green.
- An electrical supply should be available within the reach of the included power cord. DO NOT use extension cords to connect the machine’s power cord to the electrical supply. The low AMP supply could damage the mixer or cause a fire.
- The technician should install an over-current protection device (e.g. fuse or NFB) or Residual Current Device (GFCI) to prevent a current fault risk.
- Ensure that an isolating switch is fitted within 2m of the machine.
- All wiring connections must be checked and tight.
Hard Wiring
- The mixer can be hardwired into a switched socket which isolates all poles and has a minimum contact clearance of 3mm. It should be located close to the mixer for use in an emergency and to facilitate servicing.
- The machine must be incorporated into a potential equalization system.
- The leakage current for this appliance is no greater than 1 mA/KW.
- If the electrical supply cable to the machine becomes damaged, it must be replaced by the same specification or higher and suitable for the mixer’s motor load.
- The ground wire is fixed to the machine and this connection must be kept intact.
- CAUTION: The mixer MUST be grounded.
3 Phase Connection
If you have a 3-phase mixer, when it is in position and connected, please make
sure that the shaft goes clockwise. (Same direction as the arrow sticker that
located on the front of the mixer). If the shaft goes counter-clockwise,
please exchange the position of 2 phase wires: replace L3 with L2.
The mixer should be hardwired into a switched socket (see above).
Ambient Conditions
- The minimum requirement for all electrical equipment’s correct operation is an air temperature of between +5℃ and +40℃.
- Electrical equipment operates correctly when the relative humidity does not exceed 95% at a maximum temperature of +40℃.
- Electrical equipment operates correctly at altitude up to 1000m.
- Electrical equipment is designed to withstand and be protected against the effects of transportation, and storage temperature within a range of -25℃ to +55℃ and for short periods not exceeding 24h at up to +70℃.
Once the electrical connection has been made, the machine is ready for use.
Operation
Fitting the Bowl
NOTE: Install the bowl BEFORE attaching the agitator.
- Lower the bowl lift handle anti-clockwise and down to its resting position.
- Lift the bowl by the handles and slowly position the locking pin located at the rear of the bowl into the hole in the middle rear of the cradle. (Figure A)
- Lower the bowl onto the pins located on either side of the bowl cradle.
- Once the bowl is in position, secure it by pulling each bowl clamp forward until the bowl is locked tight. (Figure B)
Bowl Lift & Guard
Move the bowl lift handle anti-clockwise to lower the bowl. It is necessary to
lower the bowl to change the tools, and to provide better access for filling
and emptying the bowl. To raise the bowl, move the bowl lift handle clockwise
until it hits the upper stops.
The bowl cradle and guard are electrically interlocked so that the mixer will
only operate when the bowl is in the raised position and the guard is locked
in place. This ensures total user safety at all times.
Once the guard has been opened and the bowl lowered the mixer can only be
restarted by pressing the start button.
During operation additional ingredients can be added via the ingredients chute
located on the right-hand side of the bowl guard.
Tool Selection
The beater, whisk and dough hook are meant for the work implied by their
names. Do not use the beater for dough making or the whisk for anything other
than whisking, aerating or mixing light mixtures. These are the typical uses
for each of the tools supplied:
- Whisk: Light mixes such as whipped cream, mayonnaise, egg whites, pancakes and soufflés
- Beater: Firm mixes such as light pastry, cakes, biscuits, icing, fillings and mashed vegetables
- Dough Hook: Heavy mixes such as dough and pastry
Fitting Attachments
NOTE: Install the bowl BEFORE attaching the mixing tool.
NOTE: It is easier to install the attachment prior to adding ingredients
into the bowl.
Open the bowl guard and lower the bowl.
Slide the attachment slowly upwards onto the planetary shaft, fitting the
shaft pin through the slot in the attachment. (Figure A)
Rotate the attachment clockwise to secure it onto the planetary shaft.
NOTE: Attachments should always rotate in a clockwise direction around
the bowl. If an attachment is moving counter-clockwise please contact a
licensed electrician immediately to remedy incorrect wiring.
Operation
- Before you can start the machine, you will have to lift the bowl and close the safety guard.
- Place the gear selector handle to desired gear.
- Select time required if using timer.
- Press on button to start the machine.
- The machine must always be stopped before changing speeds. Failure to do so may damage the gears or other parts and will void the warranty.
- Never place your hand or any kitchen utensil in the bowl whilst the mixer is in operation.
- Never operate this machine with safety covers removed or with safety switches inoperative.
- When mixing is complete, turn off the machine and lower the bowl by lift handle/lever then take off the attachment.
- Then take out the bowl together with attachment.
- Finally take out the mixed ingredients.
- Please follow the capacity chart on page 11. Overloading or not following the chart will damage the mixer and void the warranty.
Speed Selection
To change speeds, first turn off the mixer, then move the gear selector handle
to the desired speed before restarting the mixer by pressing the start button.
Number 1 is the slowest speed and number 3 is the highest speed.
Slow Speed: for heavy mixtures such as bread dough, heavy batters,
biscuits, potatoes etc.
Medium Speed: for light dough which must rise quickly, heavy batters and
some whipping operations.
High Speed: for fast, light work, such as whipping cream, beating eggs,
and mixing thin batters.
The speed selected depends largely on the quantity and consistency of the
product. It is recommended that mixing is always started at the lowest speed
and progressively increased to the desired setting. In an emergency situation
always use the red emergency stop button to stop the mixer. The below table
show the recommended speeds for the range of tools.

Mixing Heavy Dough
The moisture content of heavy dough is a critical factor when selecting the
correct mixing speed. You should never use 2nd speed when mixing heavy dough
with an Absorption Ratio (AR) of 50% or less.
To determine the Absorption Ratio (AR) of a product, divide the water weight
by the flour weight.
Example: Calculate the Absorption Ratio of a mixture containing 50g of
water and 100g of flour. 5 ÷ 10 = 0.50 = 50 % = AR 1kg = 2.20462 lb ; 1 lb =
0.45359 kg
- If high gluten flour is used, reduce above dough batch size by 10 %
- Capacities listed are based on flour at room temperature and water at 20°C. If using chilled flour, water below 20°C, or ice, reduce batch size by 10%
