General Description

The product referred to in this manual is expressly designed to be coupled with WMF coffee machines for the guaranteeing the correct storage of milk at a controlled temperature.

NOTE: refrigerator has not been designed to cool down the milk from the ambient temperature (or above).

The max weight of the device (with its milk container) is 21 kg.

The A-weighted emission sound pressure level of the appliance is below 70 dB(A).

Description of Operation

**** The refrigerator operates using a refrigerant vapour compression cycle that transfers heat from the inside to the outside, making it possible to keep the liquid for human consumption stored inside it at a constant, pre- set temperature.

The refrigerant evaporates by removing the heat from the air via the cold inside walls of the refrigerator (in contact with the evaporator through which it flows) before entering the compressor. Here the pressure and temperature of the refrigerant are increased, and it is then passed through an air-cooled condenser, where it is condensed. Lastly, the refrigerant fluid returns inside the evaporator via capillary and the cycle is repeated.

The internal temperature can be varied using the digital thermostat in the frontal part of the refrigerator.

Installation and Use

• Checking the packaging

**** As soon as the package arrives, inspect it, making sure that it is not upturned and that it has suffered no damage during transport. Remove the packaging and inspect the unit for damage of any kind.

If there is any doubt as to the integrity of the system parts, do not use the refrigerator.

You must inform your dealer of any damage and/or anomalies not later than 24 hours from the delivery date

Positioning

**** The refrigerator has the overall dimensions in millimetres (in inches) shown in the figure below.

Place the refrigerator on a horizontal surface.

When choosing the position of the refrigerator, remember that a gap of at least 100 mm (4 in.) is required between the back panel of the refrigerator and any wall to allow the warm air from condensation to escape.

We recommend leaving a gap of the same size 100 mm (4 in.) between the top part of the refrigerator and any surface above it.

As far as any space requirements at the sides of the refrigerator are concerned, there are no specific instructions.

Electrical connection

The refrigerator is equipped with an IEC connection socket and a main power switch on the frontal panel.

The power cord with the proper plug for the country where it will be used is supplied with the refrigerator.

Before connecting the refrigerator to the main electrical line, make sure that the supply has the same characteristics (voltage, number of phases, network frequency and amperage) as those stated on the product label.

Grounding the appliance is obligatory and therefore you must ensure that the electrical system to which the refrigerator will be connected is grounded and that the grounding system is in perfect working order.

The manufacturer declines all liability for any damage suffered by people or property as a result of failure to abide by the above instructions.

To connect the refrigerator to the main electrical line, insert the plug into a socket without using, if possible, adaptors, multiple sockets and/or extension cords. Should the use of any of these accessories be unavoidable, only use items that comply with current safety standards and take care never to exceed their capacity (in current).

Use

The refrigerator has slots on the frontal part for ducting the pipe to pick up milk from the container placed inside the refrigerator.

The refrigerator must be used only with the provided tank, in any case with closed milk containers.

The refrigerator is provided of a digital thermostat placed on the frontal panel.

Refrigerator switch on

When the refrigerator is switched on, but in standby mode, the thermostat’s display shows alternatively “OFF” and the inside temperature value.

To turn on the refrigerator, hold the button pushed for at  least  3 seconds. You will see “ON” on the display and immediately after the inside temperature value. Once turned on, the fridge will start working, but it will take some time (also depending on external conditions) to reach the required internal temperature. We recommended to put milk inside the refrigerator only when the internal temperature has stabilized to the required value.

Temperature setting

To set the desired temperature, push the button        until you see the current set point value flashing, then adjust the value using the button (increase) and       (decrease); to store the new value press the button

. NOTE: To ensure that the milk is always maintained at temperature allowed by the HACCP, the setpoint can be varied only within a specific values range.

NOTE: The refrigerator can operate at lower temperatures than the level obtained, by setting the thermostat to lower setpoint values. However, since these temperatures are out of the envisaged range for storing milk or similar liquids for human consumption, the manufacturer advises against using the refrigerator in this way, stressing again that the appliance is designed and made to store milk or similar liquids for human consumption at a controlled temperature and not to chill such products from room temperature.

Milk level sensor functioning

The refrigerator is provided with one milk level sensor which detects the presence of milk in the container and generates an alarm when the level falls below about 0.5 litres of milk. The refrigerator can be provided also with two milk level sensors (optional) to be used with milk tank with wall divider (for two milk kind).

The refrigerator needs to be connected to the coffee machine, the milk level alarm will be shown on the coffee machine display.

NOTE: This refrigerator is designed to work with a full milk container placed inside it. In this way, if the refrigerator is working without the container or with a small amount of milk, the alarm will activate.

Refrigerator switch off

To switch off the refrigerator hold the button for at least 3 seconds

Defrosting

**** If the refrigerator is left to operate for very long periods of time, it is possible for ice to form on its inside walls.

If the ice becomes considerably thick, it is advisable to defrost the refrigerator in order to continue to guarantee good appliance efficiency and avoid higher electricity consumption.

To defrost the appliance, switch it off, holding the button of the  thermostat for at least 3 seconds; we recommend leaving the refrigerator door open to speed up this operation.

Never use tools or utensils of any type to remove ice as this could damage the evaporator, which is in contact with the inside walls of the refrigerator.

The manufacturer cannot accept any liability for damage to the appliance caused by failure to abide by this recommendation.

NOTE: During defrosting operation, do not leave the milk container inside the refrigerator.

__ At the end of the defrosting operation, after cleaning and thoroughly drying the insides of the refrigerator, switch it on holding button of the thermostat for at least 3 seconds

Installation of milk tube

The milk pumping system of Center Cooler is the assembly of following components:

• Milk Tank (1);
• Silicon tube (2);
• Milk tube connection (3);
• Milk tank cap (4);
• Milk tube;

You can use the Center Cooler refrigerator with a single coffee machine or with two coffee machines. In the first case, insert the silicon tube (2) and the milk tank caps (4) as in the figure 6A, while in the second case use two silicon tubes (2) and the milk tank cap (4) as in the figure 6B.

In all applications of Center Cooler showed in the figure 6, insert the milk tube connection in the hole of silicon tubes, with the milk tube pre- assembled (figure 7).

Setting the right length for the milk tube. The milk tube with the connector needs to reach the bottom of the cooler.

In the figure 9 is showed the specific passage for the milk tube, in orange the passage where the milk tube must be blocked. Push the milk tube until the end surface of black frontal.

If the Center Cooler is used with 2 coffee machines, you need to use the slots number 1 and 4 showed in the black frontal (figure 10). If the Center Cooler is used with just one coffee machine, you need to use slot 1 or 4 depending on the relative position of the cooler respect to the machine.

Three silicone caps are provided as accessories (figure 11).

It’s important that the silicone caps are used in the unused slots, because if they are not present in the refrigerator, you will have cold air losses.

When you have done the operations specified in this section of the manual, close the door of refrigerator and connect the milk tube at the coffee machine.

Cleaning and maintenance

Under the current regulations regarding health and safety, the operator is responsible for the hygiene of food contact materials and must maintain and clean the unit, preventing the bacteria formation.

Before performing any cleaning and / or maintenance operation, disconnect the electrical supply to the refrigerator.

This important information is written on a plate placed on the back of the product.

It’s good practice use sanitizing products for cleaning surfaces not directly in contact with food.

The outside of the refrigerator (painted steel and/or painted plastic) can be washed first with warm water and then rinsed in cold water and dried with a soft cloth. Do not use abrasive products.

To clean the inside of the refrigerator, after removing any containers of milk or similar liquids for human consumption, wipe with warm water and if necessary, a little vinegar to remove any grease. Rinse with clean water and dry with a soft cloth. Never use abrasive products, detergents or soap.

It is recommended to clean the internal part of the milk cooler’s door (areas highlighted in the picture below) using the brush supplied together with the cooler.

It is also advisable to make sure that the air-cooled condenser of the refrigerating unit at the back of the appliance is clean. If it is particularly clogged with dust, this should be removed using a vacuum cleaner.

In case of a prolonged period of disuse, we advise you to disconnect the refrigerator from the power supply, empty it completely, clean it and leave the door slightly open to prevent the formation of mould and/or unpleasant odours.
