Univex GL50 Parts And Maintenance Manual

Parts and Maintenance Manual for

GL50 Spiral Mixer

WARRANTY TERMS

Validity

: The warranty starts from the delivery date and lasts 12 months, if:

 The mixer was not damaged during transportation, and it was installed, commissioned,

used and serviced as prescribed in this manual.

 It was not tampered with, modified and no unintended tools were installed on it.

 It did not undergo modifications or repairs carried out by the customer or third parties in an

incompliant fashion or without the prior consent of the supplier

.

The following conditions constitute improper use of the mixer:

• Loading more than what is allowed or use of unsuitable ingredients.

• Cleaning with unsuitable tools or instruments that can scratch the bowl or damage the

mixer or paint.

• Use of the mixer in unsuitable places.

Warranty

If the customer finds defects in the mixer, he must immediately inform the supplier, who will carry
out a quick analysis of the lack of compliance and will establish the next steps to be taken with the
customer.

The customer must provide the needed time and opportunity to carry out modifications,
improvements, repairs or the supply of spare parts which the supplier deems reasonably
necessary. If this does not occur, the supplier will not be held liable.

Parts subject to wear

Some components are made to last far longer than that of a normal mixers life expectancy.
Breakage or malfunctioning of these pieces depends on their use. They are therefore considered
parts subject to wear and are not included in the warranty, unless they manifest evident defects in
the parts or machinery.

The parts subject to wear are: transmission belts, motors, bearings and bowl.

CONDITIONS FOR USE:

Installation requirements: The mixer needs to be installed inside of a lit, ventilated building, on top of a

solid and level support. Operating temperature range from 5 to 40°C with humidity no greater than 90%.

Lighting: the light at disposal of the operator must comply with the type of work carried out, in relation to
general lighting, according to the Standards in force. It must on any account be sufficient to read the controls
and danger signs.

Vibrations: in correct working conditions, vibrations do not create dangerous situations.

Noise emissions: 70 dbA for normal use.

Electromagnetic environment: the machine has been built to work correctly in an industrial type of

electromagnetic environment.

Environments with risk of explosion: An atmosphere capable to being transformed into an
explosive atmosphere due to room and/or operating conditions is defined a potentially explosive
atmosphere.
The mixer was not built to work in environments with potentially explosive atmospheres.

MACHINE IDENTIFICATION:

There is a plate on the back of the mixer which carries indications concerning the manufacturer, the type of
machine, serial number, electrical features, and certifications.

Storage of packed mixer:

The mixer must be stored in a closed and covered place, on a smooth and solid surface protected from dust
and filth, sheltered from atmospheric agents and hygienically safe.
The temperatures must remain between –20 and +50°C, and humidity no greater than 90%.

Installation:

The mixer must stand in a vertical position, on a smooth surface sufficiently sturdy for the load (floor with
resistance over 20 km/cm

2

).

ATTENTION.

Do not make the mixer function only on wheels, always tighten the two supports until the wheels are fully lifted.

Connection to electrical mains:

The electrical connection must be carried out by a specialised electrician, according to the
standards in force in the country where it is installed. Make sure that the voltage and frequency of
the system are the same as those on the mixer identification plate. Incorrect connection makes the
warranty void.

Preservation of the machine:

Clean the mixer thoroughly.
Disconnect it from the electrical mains.
If possible, put it back into its original packing.

Storage before a long period out of service

SYSTEM:

The installed safety systems and t he electrical system are subject to periodical checks carried out by a
specialised electrician.

Key of control intervals:

d = daily.
w = weekly.
m = monthly.
a = annually.

Master switch.
Purpose: protection of power line.
Function: this equipment separates the machinery from the mains, it is placed on
the upright of the mixer, downstream the differential protection board.

Safety micro switch of grid.
Purpose: stop the machine temporarily. Function: by lifting the protection grid, the
motor power supply interrupts, temporarily stopping the machine. To reset the
machinery functioning, lower the grid and press the START button.

Stop Circuit (emergency).
Purpose: to stop the mixer immediately and unconditionally. Function: pressing
the STOP button cuts the power supply to the mixer, stopping it totally and not
systematically. To restore functioning of the machinery, the operator must release
the emergency button and start the cycle once again by pressing the START
button.

Controls of system
Periodically the mixer's automation functioning and earthing must be c hecked.
The operating modes, safety functions, terminal board contacts need t o be
controlled as well as the integrity of the cables, luminous LEDs and ear thing
system.

O = observation: requires simple eye check (i.e. alarm light)
F = Function: requires a phys

emergency button the mixer must stop)

CLEANING AND MAINTENANCE OPERATIONS:

DO NOT CARRY OUT ANY MAINTENANCE OR CLEANING WITH ELECTRICITY
CONNECTED

To tension the belt,
remove the upper
casings, loosen the
motor bolts and act on
the appropriate register.
Fasten the motor bolts,
place the casings back
and test the machine.

*See Diagram below

To tension the chain
and the lower bowl
drive chain, remove
the lower casing (tilt
the machine) and act
on the appropriate
registers. Replace the
casing and test the
machine

*See Diagram below

All bearings and transmission parts are lubricated for life. Keep the mixer clean to
avoid flour from depositing in the moving parts thus generating bothersome creaking
and abnormal wear.

Problems with the grid
micro switch: remove
the upper protection
casing, adjust the
micro switch position
close the casing again
and test the machine.

Electrical issues must
be carried out by
qualified electrician,
with reference to the
layouts attached at the
end of the manual.

Cleaning: the mixer is not
water-proof. Do not wash it
with running water/hose. Clean
it with a moist cloth and neutral
detergents. Do not use excess
amounts of water as it is hard
to remove from the bowl.

Should a power cable
be damaged, replace
it with a H07RN/F
cable with a 3x1.5

mm2 section
