PORTOFINO RESTYLING
rev.4 - 03/2008
Gas heating regulation
Manual lighting
Turn the main switch to position 2 and wait until the machine reaches working pressure (± 0,9/1 bars - Leva: ± 1,25 bars). To light the burner, press the gas
push-button(n°1 fig. 3) and keep it pressed and light the burner with a match. Release the gas push-button after about 8/10 seconds. Use the “minimum flame”
(n°2) regulation screw to obtain the required flame height (1/1.5 cm. high), turning it clockwise to increase the flame and counterclockwise to reduce it. At this
point remove the protection cowl (det. A fig. 3) after having slackened the “knurled” nut (det.B); use the regulation screw (det. C) until the required pressure
is reached (clockwise for an increase in pressure). To increase the gas flow, turn the gas jet ring-nut (det.D) in a clockwise direction. Greater combustion(blue
flame) may be obtained by increasing the air flow through the slot in the sleeve (det. E). On the other hand lesser combustion (red flame) is obtained by re-
ducing the air flow.

MAINTENANCE
Daily cleaning operations
Preferably done in the evening:
- Clean the delivery groups’ sprays, underpan seals and filter holder guides with a sponge cloth.
- Rinse the filters and filter holders in hot water with the addition of a specific detergent, to dissolve the fatty coffee deposits.
- Fit and remove the filter holder to the group, after having installed the blind filter, and make several deliveries.
- Clean the tray and the cup support grid.
- Carefully clean the steam pipes used for heating beverages immediately after use, so as to avoid the formation of deposits which could block the delivery
nozzles and also to prevent different types of beverages heated previously from contaminating the taste of the beverage being heated.
Weekly cleaning operations
- Cleaning the group and sprays: put a teaspoon of special coffee machine detergent powder into the blind filter provided with the machine and fit it to the
group to be cleaned using the filter holder. Press the group’s delivery control push-button as for a normal coffee delivery. Stop delivery after about 30 seconds.
Repeat the operation several times until clear water can be seen coming out of the solenoid valve drain pipe. Rinse the group using a normal filter and make
a few deliveries using only water. Then make a coffee to eliminate unpleasant tastes.
- Drip tray cleaning: remove the cup support grid, slide out the drain water tray and clean it. Also check and, if necessary, clean the plastic drain tank removing
possible coffee grounds with the help of a teaspoon.
- Outer case cleaning: use a damp cloth (not abrasive). Never under any circumstances use alcohol or solvents on the written or painted parts.
