Operating procedures
7.3.1
Start-up, mixing and pre-heating of cleaning liquids
Assemble the hoses according to P&I diagram. S03 must be connected to HE lower
port and S02 must be connected to HE upper port
Fill tank/tanks with water: 90 % of total cleaning volume, calculated as per section
7.2.2.2, step 2.
CAUTION! To avoid risk of overflow, tank B02 shall not be engaged in circulation.
When in operation, the main volume of the liquid is to be in the Heat Exchanger
and a minor part of it in the main tank B01 for heating and circulation.
Pump the water volume into the Heat Exchanger - if CIP unit is 400 litre version,
start emptying tank B02 and then B01. Recirculate/clean only using tank B01, inlet
and outlet valves for B02 shall be closed.
To avoid accidents, circulate with water only to check for leakages to begin with.

The operation of valves can be done while the CIP-pump is in operation, whenever the
flow is always in circulation.
CIP equipment must never be left unattended. In case of unexpected pump stop, like for
example power failure, valves V03, V04 and V08 must be closed to avoid uncontrolled
backflow from the heat exchanger and valves V05, V02 and V12 should be opened to
allow ventilation to the top of the heat exchanger to avoid pressure build up. This is
especially important when a CIP 400L is in operation since a power failure and free
draining to a single tank causes a major risk of overflow.
Select desired temperature on the heater (recommended interval is 50-70°C) and start the
heater with the black start button.
