PORTOFINO RESTYLING
rev.4 - 03/2008
USER INSTRUCTIONS
The following should be considered general lines of operating. It is thus essential to follow the manufacturer’s instructions and regulations as regards safety.
Operating the machine is very simple and the checks that the operator must make to obtain good coffee are:
- use suitably softened fresh mains water
- boiler water temperature between 100°C and 130°C inclusive
- delivery time 20-30 seconds
- ground coffee dose between 6 and 7 g. inclusive
- constant cleaning of the coffee dosing grinder
- checking the wear of the dosing grinder’s grindstones
Normal operating values
Recommended values:
- Pump pressure: ± 9 bars
It is shown on the blue scale of the delivery manometer. It can be regulated using the pump’s bypass screw (clockwise for an increase in pressure).
- Boiler pressure: Portofino 1-2-3-4 groups ± 0,9/1 bars
It is shown on the red scale of the manometer. It can be regulated using the pressure switch’s screw (clockwise for a decrease in pressure).
- Safety valve opening pressure: ± 1.5 bars
- Expansion valve opening pressure:
- Portofino 1-2-3-4 gr.:
- 1
st
expansion valve: ± 10.5 bars
- 2
nd
expansion valve: ± 11 bars
The opening pressure can be checked via the apposite filter holder (blind) with the manometer and delivering only water: when the manometer needle stops,
the valve will start to drip.
- Coffee delivery temperature: 85/92°C
The temperature depends on the type of blend used; it can be checked with a precision thermometer during delivery. The pressure switch’s screw can be
used for minor adjustments (see boiler pressure).
How to make espresso coffee
Remove the filter holder from the group and dispose of the grounds by hitting the edge of the filter holder against the bar in the apposite drawer.
Do not hit the filter holder against an unprotected surface; the filter holder’s seal could be damaged. A smart blow should be enough. The small quantity of
powder remaining will not have a negative effect on the taste of the coffee.
Fill the filter holder with finely ground coffee, placing the filter holder in the housing provided at the bottom of the grinder-doser and pulling the lever once
for a single coffee and twice for a double dose.
Attention: always remember to pull the lever to its full extent; then let it return to its rest position on its own.
When the filter holder is filled, press down the ground coffee with the special tamp, pushing the filter holder upwards. Clean the edge of the filter holder with
the palm of the hand to get rid of excess coffee powder. This will ensure that the seal between the filter holder and the machine will be perfect.
If a filter for mixed use is being utilized, you can put a coffee pod instead of ground coffee in it.
Fit filter holder to the machine group, fixing it and turning it until it is fully in. Do not tighten too much, otherwise it will be difficult to remove after delivery.
After having fitted the filter holder properly put a previously heated cup under the spout. Two cups are required if a double filter holder is used.
When delivery is finished, remove the cup and serve it.
How to make cappuccino
For making cappuccino, fresh milk must be “frothed” to give a foam which will be poured over the espresso coffee.
Position the steam pipe and switch the steam on for 1 or 2 seconds to clean away milk residues. For heating use a jug containing at least three inches of milk.
Approach the jug to the steam pipe so as to immerse the spout in the milk. Slowly open the steam tap and move the jug in a circular fashion until the milk
starts to froth.
Then quickly close the steam. Remove the jug from the pipe and pour the frothed milk over the espresso coffee.
N.B.: the steam pipe is very hot and should not be touched until it has cooled.
Clean the milk from the pipe as soon as possible to prevent it from drying and becoming difficult to remove.
Inform the customer as soon as possible that the drink isvery hot. Keep extra frothed milk for the next cappuccino.
