6 - CONNECTION DIAGRAM
The diagram in fig. 4 shows the sequence for the connection
of a CO
2
cylinder to the ICE FROST MANUAL 2.2 (the said
cylinder is not supplied as part of the machine’s kit).
Description:
(A) Ice Frost Manual 2.2
(B) CO
2
cylinder (not supplied)
(C) Pressure reduction unit (supplied with the machine)
(D) Connection hose (supplied with the machine)
Connection:
- remove the rear panel (E) to release the hose (D) coiled
up inside between the panel and the machine itself;
- connect one end of the hose (D) to the solenoid valves,
fitted with quick couplings and located inside the machine.
- The other end of the hose (D) must be connected to the
pressure reduction unit (C), as shown in fig. 5;
- remount the rear panel (E);
- open the valve (F) of the cylinder (D) to enable the CO
2
delivery, making sure the pressure indicated on the relati-
ve reduction unit gauge is at 0.5 bar.

Note
There are two gauges on the pressure reduction unit: one
indicates the pressure of the CO
2
delivered (which, as
stated earlier, must be at 0.5 bar) and the other indicates the
quantity of CO
2
remaining in the cylinder. Obviously, when
the latter gauge reads 0 bar, this means the CO
2
cylinder is
empty and so must be replaced or refilled.
The Ice Frost Manual 2.2 is now connected to the
pressurisation components and therefore the installer can
now proceed with the following operations.
