a. Turn off the refrigerator compressor by turning
the switch (1) anti-clockwise.
b. Turn off the feed pump by turning the switch (2)
anti-clockwise.
c. Turn off the dasher by turning the switch (3) anti-
clockwise.
d. Slowly release ice cream pressure in the cylinder
until the pressure gauge (4) indicates zero using
the regulator (5) and wait for remaining ice cream
to come out of the cylinder.
e. Connect up the pump intake and ice cream outlet
to the CIP washing pipes.
f. Start up the CIP washing cycle by turning on
the CIP washing pumps (not included in the
supply of Frigus 400) and turn on the freezer
CIP cycle using the switch (6).
For additional washing instructions please refer to
the section on CIP washing in this manual.
WARNING:
Do not carry out CIP washing without turning
on the CIP cycle with switch (6): this would result
in insufficient flow for washing.
Do not turn the pump or dasher onto continuous
operation during washing: this could cause
serious damage to mechanical parts due to the
lack of lubricant.
g. Once the wash cycle has been completed
(duration must be determined by experience, and
depends on conditions of use) rinse the system
with cold clean air. Never leave the machine full
of aggressive cleaning solutions which could
corrode metal parts and damage seals.
Turn off the main switch at the back of the
machine to leave the freezer in safe condition
disconnected from the electrical supply.
Check that all indicator lights are off.
Turn off compressed air and cooling water supply
taps.
