GENERAL INFORMATION.
THIS MANUAL IS TO BE CONSIDERED AS AN INTEGRAL PART
OF THE MACHINE AND MUST BE CONSERVED WITH THE
MACHINE THROUGHOUT ITS WORKING LIFE.
Before carrying out any operation, it is important to read this instruction manual
thoroughly, particularly the section concerning risk(see page 15).
This manual should be kept in a way so that it is available for consultation at any
time and kept so that it is not damaged ( ie. protected from chemicals, humidity,
dust, sunrays, etc.).
The manufacturer has the right to modernise production of the instruction manual
without any obligation of modernising previous production of this manual.
The manufacturer is not responsible for any malfunctioning of the machine caused
by:
* Irrational, improper and erroneous use of the machine
* Contrary use (Contrary to the operation as stated in this manual)
* Incorrect installation
* Faulty power supply to the machine
* Lack of maintenance as prescribed by the manufacturer
* Modifications or unauthorised interferences
* Use of spare parts which are not original or specified for this model
* Non-adherence of the instructions contained in this manual
This machine should only be installed in a well ventilated area to ensure adequate
air circulation around the compressor. The environment where it is installed should
be free from dust and airborne particles, as this can block up the condenser. The
use of aerosol spray cans for greasing tins and trays will leave fine airborne grease
particles in the air, which when coming into contact with walls and equipment will
leave a very sticky substance which will attract dust. This is especially the case for
the condenser on the water cooler, if the water cooler is mounted above the spiral
mixer. Therefore we recommend that aerosols are not be used in the bakery for
greasing.
On delivery of the machine and after removing the packaging you should make sure
that all the components have been packed. A complete list of items is on page 2.
In case of any doubt you should consult the qualified personnel or the supplier.

CHAPTER 3:
INSTALLATION AND LOCATION GUIDE:
The machine must be installed in an environment in which the temperature does not
exceed 30 degrees Celsius.
! The machine should be fixed horizontally to a solid brick wall by the bracket
provided using all the ten plugs to spread the load of the unit evenly. Other
options are a stand which should be fixed to the wall, or a special wall bracket
which will enable fixing onto Bessa brick walls. After the bracket or stand has
been fastened to the wall, make sure that it is stable, as the machine weighs
140Kg when full. Position the electric control unit in a location where no
water is likely to splash on it and away from direct sunlight.
! Position the machine in a location where there is adequate ventilation (airflow)
ie. not in a recess in the sealing and not in front of airconditioner inlet/outlet.
as the machine produces heat and requires air circulation to remain cool. i.e.
not in recesses where the air cannot circulate around the machine.
! If the water cooler is to be placed in the ceiling, please ensure that there is easy
access for cleaning, maintenance removal if necessary and service. (Any cost
incurred in removing from, and reinstalling the water chiller in the ceiling
cavity is not covered by warranty.)
! Ensure that the area where the machine is to be installed is a clean, dust free
and free of vermin.
Follow the diagram in the chapter 6 “ INSTALLATION AND FINAL TEST” for
correct positioning and location.
! Connect the machine to a source of drinking water with a maximum pressure
of 3 bars. POLLUTED WATER SHOULD NOT BE USED IN ANY
INSTALLATION. DO NOT USE HOT WATER.
! For Electrical connection see chapter 6.
! The machine is designed to cool (or heat in models “N”) drinking water.
! The machine should be used by an operator who must have read through this
manual.

When lifting the machine a lifting device should always be used.
Always lean and move the machine in a horizontal position.
The machine should never be inclined at an angle greater than 45 degrees.
The machine should be completely emptied before transportation.

Page 10
CHAPTER 6:
INSTALLATION AND FINAL TEST.
Fasten the bracket to the wall leaving a minimum distance from the ceiling and to the
wall on the right hand side of the machine (frontal view) of at least 300mm. (See
below) USE ALL THE WALL PLUGS TO SPREAD THE LOAD OF THE UNIT
EVENLY.
Mount the Bracket in a horizontal position using a spirit level.
! After having checked that the bracket is well fastened to the wall (the machine
weighs 140kg when full) mount the machine using the special bar on the back
of the machine.
! Position the electronic key board in a comfortable position away from direct
sunlight and fasten it.
Attach the machine to a 3/4" tap of drinking water and with a maximum pressure of
3 Bars. INSTALL THE SUPPLIED FILTER BETWEEN THE TAP AND THE
WATER COOLER WITH THE SUPPLIED HOSES.
The Power should be connected to a standard 10 amp power outlet ensuring that the
machine rating corresponds to input current (these values are written on the plate
on top of the water cooler).
After having carried out the above operations, you can start the machine by pushing
the “ON/OFF” button on the control panel, if it does not turn on you should check
the electrical supply to the machine, also check that the earth leakage switch (See
page 16, (Parts diagram) Part number 7) on top of the machine is switched on. For
further fault finding refer to page 13.
Run through the working cycle (see chapter 2).
Check for any leaks on all hose connections (hose from tap to filter, from filter to
water cooler and hose from water cooler to mixer).

CHAPTER 7:
PUTTING INTO USE:
SETTING THE TEMPERATURE.
As per Chapter 2.
EXAMPLE:
To set temperature to 10 degrees press in the following sequence: “SET” “CE” 10
“SET”
If by error the wrong number is entered, wait twenty seconds or press “CE” and
repeat the operation.
SETTING THE ELECTRONIC LITRE-METRE.
As per chapter 2.
EXAMPLE:
To set-up a deposit of 20.5 litres of water press in the following sequence: 2 0 . 5
To deposit the desired quantity of water, press the “START” button and this will
initiate the flow of water with relative counting on the scale visible on the display; it
is possible to stop the counting, by pressing the “STOP” button, to restart counting
press the “START” button.
At the end of the required deposit the machine automatically stops the flow of water
and the display turns to the previous set value and can be re used by pressing the
“START” button, if in case you want to change the value press the “CE” button and
enter the new value.
In order to obtain smaller quantities of water, less than a litre, press the “CE” button
and press the decimal point “.” then the value of decilitres from 1 to 9.
It is not recommenced that the machine is used to dispense less then 5 litres as the
quantity of water left in the hose can corse inaccuracy in the deposit. If small
amounts are to be deposited ensure that the hose is completely emptied and / or it is
in the same height was maintained from the previous deposit.
! ELECTRONIC PROTECTIONS.
When over heating occurs, either due to atmospheric temperature being high or
deposits of dirt on the condenser, the compressor stops automatically and the red
indicator (located above the ON/OFF button) starts flashing.
If the cause of the over heating is accidental it will be alright to press the “STOP”
button and restart the machine pressing the “START” button after 15 minutes.
If the cause is due to deposits of dust on the condenser, it must be cleaned before the
machine is turned on again. (See Chapter 8).

Page 12
CHAPTER 8:
SERVICE MAINTENANCE:
Service maintenance of the unit should be carried out at least twice a year.
More often if required and only by authorised service companies (the cost for
this maintenance service is charged to the customer). This maintenance
consists of cleaning all the parts in contact with water, the check of the
pressure of the refrigerant, the electrical insulation, checks of all electrical
terminals and all the functions of the machine as well as the accuracy of the
deposit.
Regular maintenance should be carried out by an authorised service agent.
This ensures that the unit is functioning to full capacity and the likelihood for
a breakdown occurring is minimised.
The repairs, should only be done by qualified personnel authorised by the
W&P Reedy (see chapter 1).
OPERATOR MAINTENANCE
This is essential especially where the unit is working hard and in areas with
dust and dirty water. This maintenance should be carried out by the operator.
Clean the condenser (located on the left hand end of the machine facing the
machine) behind the safety mesh, by using a compressor with a pressure
between 2 and 4 atmosphere. (Do not use a vacuum cleaner as it would have
little effect and only clean the condenser superficially).
Ensure that the water supply filter located on the supply hose above or next
to the machine, is replaced regularly (how often depends on the water quality)
SERVICE BREAKDOWN:
! For service in case of breakdown this should be carried out by qualified
personnel only and if there is a warranty issue the repair has to be approved
prior to the service is being conducted.
MAINTENANCE & SERVICE SCHEDULE:
Daily: Clean/wipe control panel with moist rag.
Weekly: Clean/wipe water cooler with a moist rag.
Monthly: Clean evaporator on water cooler (See above).
Every 6 months: Change water filter and have the above Service
maintenance carried out.

Decibel Output
During operation, the machine emits an output of less than 82db (A).
As the positioning of the machine will vary from location to location, it has been tested for
maximum emission as set out below.
Height from the ground: 1.6 metres
Distance from the machine: 1.0 metres
From this test it is deduced by the manufacturer that the machine does not produce detrimental
noise emissions and therefore the operator does not need to wear ear protection.

Page 15
------ RISKS DANGER ! ------
A) Wrong installation of the machine
If the machine is installed in an incorrect position, (ie not horizontal), it will
result in loss of water.
Check thoroughly that the wall bracket or stand has been fastened correctly to
the wall, if it is not securely attached to the wall the machine will fall.
B) Positioning of the machine in relation to the environment and
the workplace.
The machine conforms to protection code 44IP and can therefore not be
installed in an environment where there are explosive substances in the form
of gasses.
C) Carrying and transportation of the machine.
The machine must be transported in a horizontal position and not inclined on
the side or posterior. It should always be transported on a cart and a scissors
lift used to lift the unit of the ground.
D) Objects under the machine.
The machine and / or filter might experience loss of water, it is advisable not
to put objects that can be damaged by water under the machine.
E) Risks relating to maintenance.
During maintenance, if the protecting panels are removed it should be done
with caution knowing that the refrigeration system is always under pressure,
and bursting one of the pipes will cause the flow of inflammable gas.
There is also an electrical risk as the machine has got a power coerced of 240
volts.
There is also a mechanical risk from the motor fan, if the covers are removed,
as this could be starting sporadically as it is electrical driven.
F) How to proceed with the machine.
The operator must only proceed to use machine after reading the manual
which must be available for reference at all time.
A repairer must be a professional in this field, and must be authorized to work
on this machine by W & P Reedy P/L. Before carrying out any form of
maintenance.
