2.4.1. Electrical connections
OBSERVE HEALTH AND SAFETY REGULATIONS!
If the machine is not equipped with the power supply plug, use a plug that is suitable for the voltage and amperage
values described by the rating plate and that can comply with the rules in force in the installation country.
GROUNDING OF THE UNIT IS OBLIGATORY!
Before executing electrical connetions (13), make sure the mains voltage matches the one on the plate (14) on
machine rear and that the earthing contact complies with the safety rules in force. In case of doubts about the mains
voltage, contact the local public supply Company.
2.4.2. Gas connection
Connect gas attachment (15), in case the machine is equipped with such a device, to the gas cylinder through the
proper tube (T).
Pressure of gas plant has to be set on about 2 atm., bearing in mind the max. working pressure is 4 atm.
If the pressure is not correct, act on the knob of the pressure reducer (R).
Use specific gas for food package in compliance with the rules in force about food additives in the country
where the machine is used.
Never use gaseous mixtures in presence of oxygen in a percentage higher than the atmospheric
one (~ 19%).

FEATURES OF THE ELECTRONIC CARD
The machine has 9 selectable programs.
Programmes P1÷P8 are composed by 4 modifiable variables.
Programme P9 “External Vacuum” is composed by 2 modifiable variables only (Vacuum and Extra-Vacuum).

All packaging machines are tested at works.
The parameters set at works generally prove to be fit for use.
PHASE 1 = START-UP
Press ON the main switch (1). As soon as the board has been switched on, display will show the software version, then the
last program being executed (P1÷P9).
PHASE 2 = PROGRAMS SELECTION
To select the program number, just press the buttons (6) and (7).
PHASE 3 = VARIABLES PROGRAMMING
Press button (4) to enter scheduling of the program shown at the moment. By pressing again button (4), all parameters fo
the selected program will appear one after the other. Push buttons (6) and (7) to increase or decrease the value of the
parameter shown. Parameters are stored when, while running a program, the number of the program itself will appear on
the display.
1) VACUUM
It is possible to set a value from 0 to 99,9%.
The recommended vacuum percentage is 99,9%.
Scheduling of vacuum parameter is signalled through LED (9).
2) EXTRAVACUUM
You enter scheduling of such a parameter when going beyond value 99,9%. Extra vacuum parameter is shown on the
display through letter “E”; its value is included between 0 and 30 seconds. During this time the pump keeps on extracting air
from the hood after the machine has reached the adjusted vacuum level. This function is useful especially when packing
porous products as it si quite difficult to extract air from them (for example: meat).
