The weighted sound pressure A of the appliance is less than 70 dB.
For correct operation and maintenance of the appliance you should follow this manual precisely, respecting the instructions and referring to the diagrams.

INSTALLATION

Before installing the appliance ensure that the mains voltage and power correspond to the data given in the specifications table. Take the appliance out of the packaging and put it in its final place of installation ensuring that it is stable and safe and that there is the necessary space for using it. Place the machine in a way that the distance between the grid and the floor is wider than 1,5 mt. To clean the internal circuit more efficiently, you are recommended to empty and fill the boiler a number of times and deliver simple water and coffee to be thrown away.

Electrical connection

Before connecting the power cable, follow the instructions below to install a safety switch and of the proper capacity:
Install ground cable, then phase cables. Uninstall phase cables first and then ground if needed.
Make sure the ground connection complies with existing standards and regulations.
To connect directly to the mains electricity supply, include a device to disconnect the appliance from the mains, with a contacts opening distance which allows complete disconnection in conditions of category III overtension, in compliance with the installation rules.
N.B. CHECK THAT THE DATA ON THE RATING PLATE CORRESPOND TO YOUR MAINS ELECTRICITY SUPPLY.

INSTALLING THE POWER SUPPLY CABLE

Water Connection

When installed, the boiler and heat exchangers are dry to avoid possible damage to the appliance caused by freezing.

The appliance must be supplied with cold water only.
If the mains pressure is higher than 0.6 Mpa (6 bars), you must install a pressure regulator with 0.6 Mpa (6 bars) maximum output pressure.
Connect the drain hose to the drip tray, avoiding excessively tight curves and sloping the hose appropriately to facilitate water flow.
Connect the 3/8” hose to the mains water supply, then to the water softener and the appliance.
Connect to the mains water supply in respect of national legislation.

N.B. The water softener is indispensable for correct operation of the appliance, to optimise coffee delivery in the cup and to extend the working life of components, as it purifies the water from limescale and residues that would otherwise shorten working life.
Failure to follow these instructions absolves the company from all liability.
Before connecting the pump intake tube, open the tap and run water through the water softener for about two minutes to eliminate possible.

IMPURITIES FILTER

The impurities filter (code 10355150) is normally mounted on the hose connecting the purifier to the pump (fig. A) to prevent impurities in the water from damaging downstream components such as the pumping head, flow pumps, solenoid valves, etc. The capsule filter (code 10355162) which blocks the impurities present in the water must be replaced about every three months.
The three-month period is indicative only as the actual length of time is correlated to water consumption and the impurities present in the mains water supply.
To replace the pod filter: unscrew the impurities filter (code 10355150) and replace the pod filter.
Before inserting the new pod filter, make sure the inside of the body (10355152 and 10355154) is completely clean.
Any foreign matter must be removed to ensure correct filtration.
The impurities filter must be mounted according to the flow direction indicated by the arrow (fig. A) on the body SANREMO ZOE Coffee Machine fig

Use Preliminary Check

Before using the appliance, check that:

the plug is inserted properly into the mains power outlet;
the water filling hose is correctly connected to the mains water outlet, check for leaks and that the water tap is open;
the drain pipe is positioned in accordance with the preceding instructions.

With the steam tap (B) open, place the ON/OFF switch (D) in the 1 position and wait for the water in the boiler to reach the maximum level established by the electronic control unit. If the boiler does not fill within the set time-out (90 secs.), the pump stops and the keypad LEDs flash. In this case put the on/off switch (D) to position 0 and then to position 1 to finish filling the boiler.

Now put the on/off switch (D) to position 2 so that the heating elements are powered and therefore start to heat the water.
Wait for steam to come out the steam nozzle (B), then close the tap and, using the Boiler pressure gauge, check that the pressure has reached and maintains a value of 0.8:1 bar. If it is not on this value, turn the adjusting screw on the pressure switch (+increase, – decrease, see figure below). SANREMO ZOE

Hot Water Delivery

Make sure the boiler pressure gauge shows a pressure of 0.5:1 bars. Press the button (M6) to deliver hot water, then press again to stop delivery. Take great care to avoid burns.\

Steam Water Delivery

All models have two steam nozzles on the sides of the work surface, with the exception of the one group machine which has just one. These steam nozzles are retractable and can be oriented by means of a ball joint. To deliver steam, turn the knobs (B) anticlockwise. Take great care to avoid burns.

Coffee Delivery ZOE SAP MODEL

Insert the filter holder (E) into the group head (F) turning the filter holder counter-clockwise. Press the button (M5) and wait for the required quantity of coffee to be dispensed, press it again.

Coffee Delivery ZOE SAD MODEL

Insert the filter holder (E) in its seat (F) by turning it anticlockwise. Select the type of delivery required on the keypad (M):
M1= One short/standard coffee.
M2= One standard/long coffee.
M1= Two short/standard coffees.
M4= Two standard/long coffees.
M5= Electronic settings button or continuous manual delivery.
Before use, the operator must always check the indicator (L) to make sure that the level of water in the boiler is above the minimum level.

Dispenser Programming

To access this phase keep the button M5 on the first pushbutton panel on the left pressed for over 5 seconds. The indicator lights of the buttons M5 start to blink continuously. Select the caption corresponding to the amount required and press to dispense. The indicator light of button M5 and that of the selected caption remain lit. When the required amount has been dispensed, press the selected dispensing button again so that the control unit stores the data. Repeat the above procedure for all 4 dispensing buttons on the pushbutton panel. A dispensed quantity may also be set for the hot water button (M6) by repeating the above procedure. Upon completion of the procedure, the remaining groups will automatically use the stored quantity. The other groups may, however, be programmed independently by repeating the same procedure as above after having programmed the first group on the left.
There are 2 safety systems inside the control unit designed to protect the electronic system and the various parts of the appliance. If, upon pressing a dispensing button, the corresponding indicator light starts blinking, this indicates a malfunction in the electronic system or lack of water. For safety reasons, the dispensing of water stops after 4 minutes and in any case after 4 litres of water.
The ZOE electronics also offers the possibility of reproducing the pre-brewing effect by wetting the coffee for 0.6 seconds and then stopping the subsequent brewing from starting for 1.2 seconds. This option is only applicable for single shots of coffee.

To Enable Pre-Brewing

With the appliance switched off, put the on/off switch (D) to position 1 and at the same time keep the button (M1) on the left-hand group pressed until the indicator light corresponding to the button (M5) remains lit; then release the button (M1). Now put the on/off switch (D) to position 0 and then to position 2 in order to store the operation.

To Disable Pre-Brewing

With the appliance switched off, put the on/off switch (D) to position 1 and at the same time keep the button (M2) on the left-hand group pressed until the indicator light corresponding to the button (M5) remains lit; then release the button (M2). Now switch the appliance off and then on again using the on/off switch (D) in order to store the operation.

CLEANING

Spout assembly filter: after having dispensed the last cup of coffee, the filter and filter holder must be washed with water. If they are damaged, worn or clogged, they should be replaced.
Drip tray and grid: the drip tray and grid should be removed frequently and coffee residues cleaned away.
Water softener: the softener should be periodically regenerated according to the manufacturer’s directions given in the instruction booklet.
External housing: the external housing and the steel parts should be cleaned with sponges and soft cloths to avoid scratching. Only use detergents that do not contain abrasive powders or solvents and do not use steel wool.

WARNINGS: when using the appliance it is recommended that the various instruments be kept under control, checking that they are in the previously indicated normal working conditions.
When the appliance has been left unused for a number of days, or every 2/3 months during normal use, to clean the internal circuits more efficiently, it is good practice to fill the boiler a number of times and deliver simple water and coffee to be thrown away.

Warning – correct use of rotary pumps

Proper Alignment of Pump and Motor
On occasion the noise of a motor-pump assembly is caused by a poor alignment.
When the coupling between motor and pump is rigid, the pump rotor and the motor rotor may be out of axis. If this condition is maintained over time the most likely damage is seizure of the pump.
An efficient solution of this problem is the use of an elastic coupling between pump and motor. Fluid-o Tech supplies an optional kit code N. 10051020.
Quality of Water.
Tight mechanical tolerances of components and materials used for rotary vane pumps require a very clean water, free from suspended particles. Sand, deposits on connecting pipes or the resins of the sweetener, when flowing through the pump, may scratch graphite parts causing problems of insufficient pressure and flow rate. If a closed loop hydraulic circuit is not available to guarantee a clean water and no sources of contamination Fluid-o-Tech recommend to install a 5-10 micron filter between the sweetener and the pump. Recommended filter: food approved polipropilene wire cartridge. Keep the filter clean.: an upstream dirty filter will create cavitation and the pump will break shortly (see section 4).
Dry operation
Rotary vane pumps may operate in dry condition only for a very short time- few seconds! Without a proper water cooling the temperature of the mechanical seal will increase very quickly with resulting breakage. The most likely impact is a remarkable leak visible from the four drain holes close to the motor clamp . For potential lack of feed from city water line Fluid-o-Tech recommend the installation of a minimum pressure safety switch upstream from the pump. In case of feed from a tank install on the tank a minimum level switch
Cavitation
Cavitation shows when feed flow rate does not match the pump design requirement: most frequent causes are dirty filters, small diameter pipes,more users on the same line. Opening of the safety valve (generally installed upstream from pump and filter) must happen before the pump start up. This will avoid cavitation. For the same reason closing of the safety valve must be delayed after the pump shut down. The most noticeable effect is an increase of noise. If cavitation continues the impact is the same as of dry operation
Back Feed of Hot Water
If a non return valve between the pump and the hot water vessel is defective the pump may come in contact with hot water(90-100°C). Dimensional
variations of components will cause seizure of the pump
Wrong connections
Pumps connectors are 3/8”NPT(conical) or 3/8” GAS(cylindrical). Connectors with thread different from the recommended type are occasionally used. Sealing is made with a glue or with teflon tape. If the connector is forced it is possible to create beards; if excess sealing glue is used the extra quantity of glue may enter into the pump body. In both cases it is likely to create a damage.
Pressure strokes
To avoid pressure strokes opening of solenoid valves installed downstream must happen before the start of the pump. For the same reason closing of the valve must be delayed after stopping of the pump. A pressure stroke may break graphite parts and damage mechanical seal causing blockage of the pump and leaks
Handling
A crash on the floor may create deformations that will jeopardize the tight mechanical tolerances of the pump components. For the same reason be
very careful when clamping the pump to mount or demount connectors.
Scale build up
Scale deposits will quickly show on inner components when using hard water, not sweetened with ion exchange resins. Scale formation increases when the pressure relief valve is used as flow rate regulator: the rate of scale deposition increases with increasing of closed loop circulation. Scale deposits cause an increase of torque, occasional seizure of the pump or a reduction of operating pressure because the pressure relief valve cannot work properly.
To minimize this problem Fluid-o-Tech suggest to use pumps with flow rate matching the hydraulic circuit features. In some circuits it is advisable to periodically remove scale with a chemical treatment
