Internal Cleaning: Manual Cleaning - OMAC B Series Operation And Maintenance Manual

Rev.4 del 01/2011 O.M.A.C. s.r.l.
On the basis of the indications given by the plant manufacturer, activate the CIP/SIP.
The duration of CIP/SIP depends on the type of process fl uids treated. In order to ensure sanitisation of the LDPU, O.M.A.C. s.r.l. recommends the
CIP/SIP to last at least 1 hour.
ATTENTION
At the end of the CIP/SIP, but before restarting the plant, the safety valves must be re-set at the working pressure value, this activity must follow what is
indicated in section 3.3.3 of this manual.

3.4.1.2.2 Internal cleaning: manual cleaning

Manual cleaning activities must be carried out with the plant switched off and insulated from its energy sources; in addition the operator must wear P.P.E.
as indicated in chapter 1, section 9.
Manual cleaning activities entail:
a) disassembly of mechanical elements;
b) treated alimentary process fl uids removal/extraction operations;
c) washing and sanitisation activities;
d) rinsing;
e) sterilisation;
f) reassembly of the previously removed mechanical elements.
Wear the P.P.E. as per Chapter 1, Section 9, paying attention to identify, on the basis of the thermal features of the treated process fl uids, the gloves to
wear;
ATTENTION
Cleaning activities must be carried out by the operators in charge of running the plant, therefore they must be read, understood and carried out carefully
by these operators.
DANGER
Cleaning and sanitisation activities must be carried out with the plant switched off and insulated from its energy sources: electrical, pneumatic, hydraulic.
The operator in charge of this activity is obliged to wear the P.P.E. indicated in chapter 1, section 9, in order to ensure their safety.
a) The disassembly activities refer to the following mechanical elements:
• front cover;
• rotor blocking nuts;
• rotors;
• gaskets;
• any optional features (mechanical or pneumatic safety valve).
These elements must be disassembled following the indications contained in chapter 5, section 5.8, 5.9, 5.10 of this manual.
ATTENTION
During disassembly and assembly operations of the components listed under letter a), strictly follow the indications in sections 5.8, 5.9. 5.10.
b) The alimentary process fl uids removal activities consist in manually removing most of the fl uid present and seeing to its disposal.
c) Washing and sanitisation activities concern the previously disassembled single components, as well as the pumping chamber. Using a water and
degreasing detergent solution, wash the single components and the pumping chamber, paying particular attention to the seals area and shafts threaded
area.
d) Wash with plenty of aqueous solution until the visible process alimentary fl uid is completely removed.
Once the alimentary process fl uid has been removed from the contact surfaces, sanitise all the components that come into contact with the fl uid. To do
this:
• prepare aqueous solution of sodium hypochlorite (5%);
• sanitise all surfaces in contact with the alimentary process fl uid carrying out the operation for at least 15 minutes
ATTENTION
Sanitise all surfaces in contact with the alimentary product proceeding for at least 15 minutes
• with cold running water, rinse all the previously sanitised surfaces, making sure all traces of sanitiser are removed.
e) Sterilise the previously sanitised surfaces with water steam.
f) Reassemble the previously removed mechanical elements following the indications contained in Chapter 5, section 5.8, 5.9, 5.10 of this UMM.
After having assembled the clean and sanitised pump components, remove the protective sheets, placed on the electric panel, electric motor and cable
shunt/connection boxes and subsequently connect to the energy sources, disconnected before starting manual cleaning.
