4Installation
4.1 Positioning
• The equipment must be placed on a surface capable of bearing the weight of the chiller
full of water. Install the equipment following the schematic described in this user guide.
• The chosen position must allow satisfactory ventilation; there must be a gap of at least
10 cm (3.9 in) around the back and top for ventilation.
• The equipment must not be placed close to direct or indirect heat sources (ovens,
stoves, radiators, etc.).
• The electrical connection and water supply points must be close to the equipment must
be located in such a way the power cable and water hose do not form an obstruction.
• The appliance must not be installed where water jets can be generated. Do not spray
water on the device; this could cause electric shock or fires.
• The equipment is not suitable for external use.
• The equipment must be placed so it is protected from rain and water splashes, and in a
location with the temperature appropriate to its climate class (stated in specification);
otherwise, warranty rights are forfeited, and malfunctions may occur.
4.2 Electrical Installation
• When installing the chiller, always observe the local regulations and standards.
• The chiller is supplied with a moulded power cord.
• A suitable mains power supply socket should be available within easy access of the
chiller so that it can be disconnected easily after install.
4.3 Plumbing Installation
• Ensure that the chiller is installed according to local plumbing & water regulations.
• Fit a stop valve on a cold-water line and attach a 3/8” BSP male fitting, (E.g. 3/4” x 1/2”
311 or washing machine type stop valve).
• Connect water supply lines following the installation drawings. As per installation guide
in the User Manual (starting page 8).
• Push the pipe firmly into the fittings until locked into position to avoid leaks. 15mm is
the correct depth of insertion.
• In case filter systems are used verify that they satisfy the requirements of the legislation
in force.
• The chiller has a pressure reducer in case the incoming water exceeds 3 bar.
• Turn on the water to flush any impurities, dust etc. from the inlet hose and water pipe.
• Allow several litres through. Especially for new installations.
4.4 CO2 Installation
There are two CO2 installation options with this chiller, either an inbuilt 360-410gr/60L gas cylinder
or an external CO2 cylinder.
Internal gas cylinder
Open the side door. Install the CO2 cylinder into the machine. A compatible gas cylinder to use is the
Sodastream 60L cylinder https://sodastream.co.uk/pages/co2-gas-cylinders Once the CO2 cylinder is
installed, the yellow CO2 light stops flashing on the font of the machine.

8
• External gas cylinder
The machine has an external gas connection for an 8mm hose (not provided) in the rear; you must
supply appropriate pressure gas (0.4MPa). Only use super-dry, food grade CO2 hose. Before
connecting the pressure reducer to the gas cylinder, always vent any dirt from the valve. Close the
cylinder valve after a few seconds.
The cylinder must be replaced when the needle of the reducer high pressure gauge is in the red
segment or when the CO2 light on the front of the chiller flashes.
1. Record the pressure values set on the pressure reducer, then fully close the bottle using the valve.
2. Remove the pressure reducer or disconnect the high-pressure hose from the bottle if fitted. Check
the condition of the gaskets between the reducer and the bottle, replace them if necessary.
3. Replace the CO2 cylinder by slowly opening the valve to the fully open position and check that the
pressure values are as originally set.
Gas cylinder location
To prevent the risk of injury or damage the CO2 cylinder must always be kept in a vertical position
against a wall, held in place by a chain and fixed to a bracket. Do not expose the bottle to heat
sources or very low temperatures.
Pressure reducers
There are different types of CO2 cylinder available. Always use a pressure reducer suitable for the
type of valve on the cylinder. If you use CO2, especially in a small area, ventilate the contaminated
area at once.
We advise using a Dual gauge CO2 regulator, Marco part number 1400195. Check for leaks using a
solution of soapy water.

1860864 FEP Tubing 8mm OD for external gas supply
4.5 Backflow Prevention
This chiller must be installed with adequate backflow protection to comply with all applicable
federal, state and local codes.
4.6 Thermostat Setting
The temperature of the dispensed beverages cannot be adjusted.

5Overview & Operation
5.1 Before Using the Chiller
•Before connecting the chiller to the power source, let it stand upright for approximately 2-3 hours,
this will reduce the possibility of a malfunction.
•Check that all installation procedures have been carried out.
•Ensure water inlet is open.
Wait until the pump stops running before turning on gas or installing cylinder in the machine, to ensure
the gas does not block the system.
•Ensure CO2 valve is open.
•Before supplying power to the chiller check water and CO2 lines do not leak.
•Plug the chiller into a suitable socket and turn the Cooling Switch on the rear of the chiller to the ON
position.
•When the unit is on, the carbonation pump starts to fill. The carbonation device stops when it reaches
the maximum level.
•If using an external CO2 Cylinder, on the pressure reducer knob, adjust CO2 pressure to a value
between 50 and 65 PSI (350 and 450 kPa) (3.5 - 4.5 bar) This value depends on the temperature of the
water and on the ambient temperature. The temperatures correspond to the CO2 pressure.
•The chiller will take approximately 70-120 minutes to get down to temperature depending on the
temperature of your incoming water. The blue light on the front of the chiller remains flashing during
this time.
•Once the blue light stops flashing and remains solid the water is chilled and at optimum temperature.
•To enable the filling of lines, push the font buttons in the following order sparkling water, cold water
& hot water until the flows appear.
•At this point you can dispense water.

6.4 Sanitization
Sanitisation should be performed:
-every 6 months in use.
-after an inoperative period of one or more weeks.
-If the system is installed in Hospitals, Schools, Elderly people’s homes, or Clinics, it is
recommended to sanitise every 3 months.
Sanitisation to be performed using the following accessories:
Need to add these once CO for sanitizing cartridge is raised and approved.
6.4.1 Preparing the Chiller for Sanitization
1. Turn on water and flush at least 4 liters (1 gallon) through entire system (plain and carbonated
water circuits).
2. Disconnect water line from main water supply.
3. Dispense both plain and carbonated water, until only CO2 is dispensed.
4. Close the CO2 cylinder and dispense carbonated water to remove CO2 pressure completely.
6.4.2 Sanitising
1. Turn off Electrical Power Supply.
2. Turn off the Cooling Switch on the back of the unit to turn the compressor off.
3. Replace the filter cartridge with a sanitizing filter recommended by Marco and fill with clean water
and with sanitizing fluid in the concentration and contact time recommended by the manufacturer.
4. Disconnect the water connections and connect them to the sanitization cartridge.
5. Turn on water mains and power supply mains.
6. DO NOT TURN ON COOLING SWITCH AT THIS TIME
7. Flush all lines (Cold and Sparkling) with sanitizer by pressing the buttons on the FRIIA font until
you can smell the sanitizing product which may have a characteristic smell, or colour. Colorimetric
test strips can also be used to make sure the entire line is filled with the sanitizing liquid.
8. NOTE: A container and drain basin will be required to collect water from the FRIIA font.
9. Be careful: respect the sanitiser concentration and contact time recommended by the
manufacturer; using extra liquid will neither improve nor speed up the treatment process.

7Accessing the Internal Components of the Chiller
1. Disconnect the machine from the electrical supply.
2. Disconnect all water and CO2 connectors.
3. Purge the CO2 from the machine, using the font.
4. Release the BOILER and FONT harness connection.
5. Drain the machine of water. Please note the ice bank needs to be defrosted before fully
draining the machine.
