INSTALLATION

The machine must only be installed in places where it is easy to use and access.
The support surface must be levelled, dry, smooth, stable and at such a height that the base is at least 100/105 cm approx. above the ground. (fig._4.1)
Do not use or install where water jets are used.
In order to ensure normal operation, the

machine must be installed in areas where the room temperature is between +5°C and +36°C and humidity does not exceed 70%.
Ensure that there is an open area of at least 10 cm on each side and behind the machine to allow adequate ventilation and facilitate its use and the performance of any maintenance operations. (fig._4.2)

If the machine is wet or very damp, wait until it is completely dry before installing or using it.

4.1 Filling the water tank

Make sure to use water with a degree of hardness suitable for this type of machine (see par. 3.6 page 51)
The machine has to operate with clean soft drinking water. Never attempt to operate the machine with water of a hardness other than that specified in paragraph 3.6.
Lift the tank chamber cover (1 fig. 4.4) and fill with water up to the “MAX” level indicated (about 1,9 L). The manufacturer recommends inserting a softener bag (2) in the water tank.

Pay attention to only pour water into the water tank, use a funnel if required. (to remove the tank for cleaning see chap. Maintenance page 62). Reposition the cover of the water tank chamber.

Check the package for validity of the softener used (quantity of litres)

4.2 Electrical power supply
Before connecting the machine ensure that the identification label data comply with those of the local electric mains.
The earthing system must be carried out in accordance with the provisions of current legislation.
Connect the power cable. (fig._4.4)

Place any excess cable on the worktop, so that it cannot be pulled by children or cause tripping.
CAUTION:
If the power cable is damaged it is to be replaced by the manufacturer or by their technical assistance service or by a person with equivalent qualification, in order to prevent any risks.

START-UP

We assume the machine has been installed correctly.
■ Make sure that the lever is positioned vertically (OFF – fig._5.6)
■ Turn the On/Off switch (1 – fig._5.1) from position “O” to “I”. After switching it on you get:
APPARTAMENTO model: the indicator light (2 – fig._5.1) lights up steady green.
APPARTAMENTO TCA model: the indicator light (2) is blue when switched on and turns white when the machine is running.

APPARTAMENTO model: you should hear the sound of the pump.
APPARTAMENTO TCA model: you should hear the sound of the pump and the indicator light (2 – fig._5.1) will flash with a BLUE light.
When the boiler is correctly filled with water, the pump stops (the noise stops).
■ Then close the steam knob.

The boiler heating begins.
Wait for the boiler pressure gauge (4 – fig._5.3) to indicate approximately 1 bar.
■ Open the steam knob (3 – fig._5.4) for 5 seconds to allow some steam to come out.

This operation is highly important as it eliminates any vacuum inside the boiler which may cause milk to be sucked into the boiler once steam dispensing has begun. Close the

steam knob again.
■ Wait for the boiler pressure gauge (4 – fig._5.3) to reach 1 bar again.
■ Fully raise the coffee dispensing control lever (4 – fig._5.5). Drain a cup of hot water from the infuser unit head (5).

This operation must only be performed once at first use.
■ Lower the coffee dispensing lever completely to stop the water flow (fig._5.6)

■ The machine is now ready for use
Allow a heating time of 15-18 minutes so that the head of the unit is fully heated: the quality of the espresso will be greatly improved with a hot unit and portafilter inserted.

MACHINE OPERATION

Make sure that the machine is ready for full safety operation as described in the previous chapters
CAUTION:
The portafilter unit heats up when the machine is ready. Pay attention
It is recommended to perform a first water dispensing without coffee with a new portafilter or on first use. This operation is recommended to eliminate any processing residues

1. Install the portafilter by inserting it into the unit head and rotate the portafilter handle from left to right. The portafilter is inserted properly once it is firmly inside the unit head and the handle is positioned at 90 degrees from the front of the machine (fig._6.1)
2. Now raise the coffee dispensing control lever to start the water flow through the portafilter. (fig_6.2)
3. It is important to leave the portafilter hooked in the unit head when not in use. The portafilter must remain heated for an optimal brew process. It will also prevent the seal inside the unit head from drying out prematurely.

6.1 Coffee preparation

1. Choose the portafilter for the preparation of one or two cups in a single dispensing (fig._6.3).

2. Fill with ground coffee and press (fig._6.4), removing any coffee residues on the edge of the filter

3. Hook the portafilter to the dispensing unit and place the cup(s) under the coffee dispensing spout.

4. Start dispensing by raising the coffee dispensing control lever. To stop dispensing, lower the lever again. On the TCA model, the LED flashes white during the dispensing phase and returns to steady when dispensing is finished (fig._6.5).
   The maximum duration of a single dispensing is 100 seconds. After this time, dispensing stops automatically even if the user has not closed the lever.
   Dispensing has priority over filling: if dispensing is requested while the machine is filling water, filling is temporarily suspended and dispensing begins regularly.
   It is possible to dispense even when the boiler level has not yet been reached.

5. Remove the portafilter to empty and clean it and then hook it up again (fig_6.6)

6.2 Steam dispensing
With the machine switched on and pressure gauge in pressure (see chap. 5 p. 22) steam can be dispensed from the steam wand.
Take a jug and place the steam wand into the drink and open the steam tap (3 – fig_6.7)

Once the desired dispensing is complete, close the tap and remove the jug.
Clean the wand with a damp cloth.
Dispense steam for a few seconds and then clean again with a damp cloth (fig_6.8)

CAUTION:
The jet of steam may cause burns. To avoid burns, use the small plastic handle to move the steam wand.

For best results:
store milk at ≤ 5°C (≤ 41°F)

6.3 Water dispensing
To dispense hot water, open the corresponding tap (1 fig._6.9) and release therequired amount of water into a cup orcontainer. To stop the hot water supply,close the tap itself.
CAUTION:
the water is very hot.Take care to avoid possible burns

6.4 ECO mode
With ECO mode enabled:
The machine APPARTAMENTO goes into standby mode after 60 minutes of inactivity.
The machine, APPARTAMENTO TCA, goes into standby after 30 minutes.
When the machine is in standby, all heaters are off and delivery is not possible. The machine exits standby by operating the dispensing lever.
On the APPARTAMENTO model, the ECO-ON mode is activated by pressing the button below the machine (fig_6.10), while on the APPARTAMENTO TCA model it is activated during programming.

The machine is supplied from the factory with the ECO mode activated.

PROGRAMMING

(APPARTAMENTO TCA only)

The machine, which is being tested, has already undergone basic programming and is therefore ready for use.

The user can vary certain machine parameters by entering the ‘programming’ mode and operating the coffee dispensing lever (1 – fig_7.1) and indicator light. (2)

The user-modifiable parameters are as follows:

1. Boiler pressure (red).
2. ECO MODE of the machine (green).

7.1 Access to programming
To access programming, the user must proceed as follows:

| 1. Turn off the machine by turning the selector switch to the OFF position
---|---
| 2. Raising the coffee dispensing lever
| 3. Switch on the machine
| 4. When the indicator light changes colour (yellow) lower the dispensing lever
2 (within 3 seconds).
The machine is now in programming mode
| 5. To switch from one parameter to another, confirm the previous one by holding the lever up for 3 seconds (waiting for
the light to go on) and only then lower it.
| 6. Each parameter is identified by an indicator colour and its number of flashes determines the setting value as described in
the table below

7.2 Programming parameters

7.3 Saving a programming parameter

| 1. After identifying the number of flashes corresponding to a certain parameter, lift the dispensing lever, holding it in  osition
for 3 seconds, until the light remains steady.
---|---
| 2. Confirmation that the parameter has been saved is confirmed by the steady LED light. Lower the dispensing lever to move to the next parameter.

Example of MEDIUM BOILER PRESSURE setting.

1. Enter the programming mode, the light is flashing once in RED colour indicating the LOW Boiler Pressure setting.
2. Raise and lower the lever, the RED light will flash twice, indicating the MEDIUM Boiler Pressure setting.
3. Keep the dispensing lever raised until the steady RED light is displayed.
4. Steady RED light confirms that the parameter has been saved. Lower the lever to move on to the next parameter.

To exit programming, restart the machine by pressing the main switch.

7.4 Changing the status of a parameter

| 1. To switch between states of a parameter (number of flashes) quickly (within 3 seconds) raise and lower the dispensing lever.
---|---

7.5 Parameter reset (Factory Reset)
By means of this procedure it is possible to delete all set parameters and restore the originalfactory setting. This function should be used in those cases where errors or unwanted varia tions have been introduced, choosing to reset everything and return to the initial conditions.

This procedure is carried out as described below.

| 1. From Machine OFF, switch the machine ON with the unit lever in the dispensing position (contact closed); the  machine does not perform any action but waits for a few seconds for a sequence from the operator.
---|---
| 2. Keep the lever in the dispensing contact position.
After a few seconds, if the lever has always remained in the same position, the machine turns on the yellow light (as for
normal programming) for 5 seconds until the flashing green light appears.
| 3. If, within 3 seconds of the green light coming on, the lever is returned to rest, a factory parameter reset (default) is implemented, indicated by the permanence of the steady green light. If, on the other hand, the lever is left in the dispensing position, after the 3-second time limit has elapsed, the green indicator light will remain flashing without  performing a parameter reset, waiting for a Poweroff.
| 4. Switch off the machine and if the reset procedure is not implemented, return the lever to the home position anyway.

MAINTENANCE

Maintenance operations must be carried out when the machine is off and cold. Some particular operations must be performed when the machine is operating.

Do not clean the machine by using metal or abrasive devices, such as steel wool, metal brushes, needles, etc. or general detergents (alcohol, solvents, etc.)
When necessary, use special detergents for coffee machines that can be purchased in specialised service centres.
Keeping your machine clean will prolong its life and produce better espresso beverages.

8.1 Cleaning the steam wand

1. Clean the steam wand after every use by wiping with a damp cloth. Turn the steam wand on to release condensation and milk residue.
2. If the steam jets become clogged with the powdered milk, unscrew the nozzle and unlock/clean with a paper clip (fig._8.1).

8.2 Cleaning the dispensing head BACKFLUSHING

1. Remove the filter basket from the porta- filter and fit the blind filter (A – fig_8.2).
2. While the brew water is flowing loosely insert the portafilter into the unit head, rotating the portafilter back and forth (B – fig_8.2). Keep emptying the blind basket of hot water until the water runs clear.
3. Backflush the unit head every day.

DISPENSING UNIT HEAD

1. Every week, after backflushing, add a small amount of espresso cleaning detergent to the blind basket. Dissolve the detergent in hot water and insert the portafilter into the unit head. This detergent is available from every authorised dealer.
2. Open and close the unit dispensing for about 10 seconds. Repeat several times.

REMOVING THE SPRAYER, DIFFUSER AND HEAD GASKET

1. Using a small slotted screwdriver, pry the inner edge of the sprayer (1) and remove it together with the gasket (2) as shown in fig_8.3.
2. With the same screwdriver, unscrew the diffuser (3) from the head (fig_8.4).
3. Scrub the inside of the unit head with the unit cleaning brush supplied (fig_8.5).
4. Using a damp cloth, clean the areawhere the portafilter connects to the unithead.
5. Soak the metal parts that have been removed in a solution made from 2 teaspoons of espresso cleaning detergent and hot water. Soak for 10 minutes. Rinse thoroughly, clean and reassemble.
6. Screw the head diffuser back on respecting the order shown in figure 8.6. Lastly, insert and hook the sprayer with its gasket

If the elements of the head are worn or damaged, replace them. These items are consumables. Contact your authorised ROCKET dealer.

8.3 Cleaning the portafilter
PORTAFILTER

1. Remove the filter basket from the portafilter handle using a small screwdriver or the under-side of the blind basket (fig._8.7).
2. Wipe the inside of the basket and portafilter clean with a damp cloth.
3. If the coffee oils have built up, soak the metal end of the portafilter and basket in the same detergent solution as the brass shower foil described above.
4. Rinse thoroughly, dry and reassemble.

8.4 Cleaning the water tank
Periodically remove and clean the water tank with warm soapy water.
To remove the tank, lift the cover (1 -fig._8.8) and extract the tank (2) using the handle: perform an upward movement.

When reinserting the tank, be sure to firmly press down so that the bottom tank tap is fully engaged.
Use fresh, filtered water to fill the tank.
Do not use distilled water (see par. 3.6 page 51).

8.5 Cleaning the drip tray

1. Remove the grid and the tray and wash with warm soapy water. Rinse and dry. (fig._8.9)
2. First reassemble the tray, making sure thatit is placed and inserted (with horizontalmovement) until it reaches the “stop”, after“hooking” has taken place (a magneticclick at the end of the stroke should beheard – fig._8.10)

CAUTION: If the tray is only left resting and not fully inserted, the water coming out of the group and from the drain flows into the front part of the base and could come out of the machine.

8.6 Descaling

1. ROCKET does not recommend removing limescale from the espresso machine. Con- tact an authorised ROCKET centre for descaling.
2. Many of the chemicals used to descale espresso machines are particularly aggressive. These chemicals can cause internal corrosion of hard metals used in the construction of the machine.
3. Additionally, it is very difficult to remove all the descaling solution from the machine once the procedure is completed.
4. Check the quality of the water you use in the machine, always using filtered water.
   Distilled water may lack the necessary conductivity required for various electronic functions needed in the operation of the machine.

8.7 Boiler water replacement

It is recommended to change the water in the boiler periodically, at least once a month or, in the case of frequent use, every fortnight.
Read all the steps described below carefully before performing the operation; if in doubt, contact the ROCKET service centre for clarification and support.

IMPORTANT:
This operation must be carried out with the machine just turned off with hot water and the boiler pressurised (fig._5.4).

To carry out the boiler water change procedure, simply open the water nozzle (fig._8.11), repeating the operation twice.

■ Check that the shower foil is not blocked: it may need to be back-flushed or be removed and cleaned
■ Check the spout of the handle is not blocked. If it is dirty with rancid coffee oil, it will need to be soaked in an espresso head cleaning solution.
Water leaking from the portafilter
■ Check the head gaskets. If visibly worn, they will need to be replaced.
■ Ensure the portafilters are kept in
place on the head whenever the machine is not in use, as this will help to protect the seals.
Espresso is too cold
■ Check that the cups are hot enough. Cups can be heated by pouring hot water into them, and then discarding it, before starting the extraction.
■ Too much water may have been drawn from the unit head. Let the machine rest and limit the amount of water drawn from it between extractions to ensure the machine remains at temperature.
Water underneath the machine
■ Check that the tray is inserted correctly
■ Check that the drain tray has been emptied
The machine appears to be off but the switch is in the ON position
■ Check that the Eco mode function is active by operating the coffee control (see par. 6.4).
■ Switch the machine off and on again from the main switch (see 1 – fig. 3.2 – 3.3)
Espresso tastes bitter
■ Extraction may be too slow. Check that the grinding is not too fine. Correct the grinding and make it coarser.
■ The machine may be dirty. Backflush again and clean the unit head. Clean the portafilters and filter baskets.
Espresso tastes sour
■ Extraction may be too fast. Check that the grinding is not too coarse. Correct the grinding and make it finer.
Espresso is watery and thin
■ Extraction may be too fast. If so, the cream will be pale. Check that the grinding is not too coarse. Correct the grinding and make it finer.
Espresso is bubbly
■ The water in the machine may be too hot. Let some water flow from the unit head. Perform another extraction.
■ The coffee may be too fresh.
Low or no pressure from the steam wand
■ It may be due to excessive use of the unit head. Excessive use of the steam wand. Give the machine time to recover pressure.
■ The steam wand may be clogged with dry milk. Remove the nozzle and clean it as indicated in point 7.1.
Milk is thin and bubbly
■ Ensure the milk is diluted gradually. If air is introduced too quickly, large bubbles will form.
■ Make sure that the steam comes out with the right pressure and that there are no blocked nozzles.
■ It may be due to using reheated milk. Try again with fresh milk.

For any type of problem not specifically indicated on this page, turn off the machine by pressing the main switch, dis- connect the plug and contact our technical assistance.
