Rev.4 del 01/2011 O.M.A.C. s.r.l.
•
CIP;
•
manual cleaning.
Below the two methods are explained better.
3.4.2.2.1 Internal cleaning: CIP
As well known, the CIP/SIP is a cleaning method of the entire plant that does NOT require the disassembly of parts and/or accessories inside the same
plant. The CIP is therefore a cleaning activity of the plant of which the LDPU is an integral part and therefore in turn affected by it.
ATTENTION
Before carrying out CIP one must perform each of the operations described below.
If the LDPU has been supplied with one or more accessories listed in section 3.3.3 of this UMM, before starting CIP, check the following:
•
adjust the pressure of the safety valves (re. section 3.3.3 letters a,b,c) at a pressure value below the maximum pressure of the same CIP, thus
ensuring opening of the valve when washing the plant;
•
ensure that the auxiliary units (fl ushing unit, cover heating and aseptic circuit), if present, are connected to the pump and work;
•
if the customer envisions the LDPU to actively participate in the CIP, activate operation of the same LDPU.
On the basis of the indications given by the plant manufacturer, activate the CIP.
The duration of CIP 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 to
last at least 1 hour.
ATTENTION
At the end of the CIP, 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.
3.4.2.2.2 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) chemical process fl uid removal/extraction operations;
c) washing and sanitisation activities;
d) rinsing;
e) reassembly of the previously removed mechanical elements.
Wear the P.P.E. as per Section 1.9 of Chapter 1, paying attention to identify, on the basis of the thermal features of the 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
Manual cleaning 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 chemical 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 chemical fl uid is completely removed.
Once the chemical process fl uid has been removed from the contact surfaces, clean all the components that come into contact with the fl uid.
