ATTENTION
The hygiene level of the LDPU can be identifi ed as LEVEL 1, according to UNI/EN standards, therefore the activities described below are carried out in
order to restore
the same hygiene level.
Cleaning and sanitising activities that concern the "B series lobe displacement Pump Unit" are divided according to two different contexts:
•
external: DO NOT affect surfaces in contact with alimentary fl uid;
•
internal: affect surfaces in contact with alimentary fl uid.
Below are the descriptions of the cleaning and sanitisation methods mentioned above.
3.4.1.1 External cleaning instructions
These cleaning activities are carried out manually, using the instruments needed to enact them, provided by the Customer and indicated below:
•
pressure washer connected to waterworks under pressure;
•
NON aggressive detergent with degreasing surfactants;
•
wear the P.P.E. already provided by the Customer and Manufacturer of the plant in which the LDPU becomes an integral part, PPE that must
take into account what is indicated in the safety sheet of the detergent used.
After having put the detergent in the pressure washer and before going any further, cover the electric control panel, the electric motor and machine wiring,
paying particular attention to the cables input into the shunt/connection boxes, with nylon sheets, fastened securely.
Paying attention to NOT direct the water jet onto parts covered with nylon sheets and indicated above, switch on the pressure washer and proceed with
the cleaning the LDPU, orientating the water jet under pressure only towards the external surfaces of the pump, part of the LDPU, as well as the fi xing
base on which the pump is fi xed.
ATTENTION
DO NOT direct the jet onto parts covered with the nylon sheets such as: electric control panel, electric motor and wiring in the machine. Pay utmost
attention to NOT wet the cables input into the shunt/connection boxes.
If required by the manufacturer of the detergent used and if specifi ed on the relative information sheet, rinse using cold water only.
3.4.1.2 Internal cleaning instructions
The cleaning and sanitisation activities of the surfaces in contact with alimentary products develops according to the following diagram, following the
indicated frequency:

Cleaning the surfaces in contact with the transferred process fl uid articulates further into two different methods, as shown below:
•
CIP/SIP;
•
manual cleaning.
Below the two methods are explained better.
3.4.1.2.1 Internal cleaning: CIP (Cleaning In Place)/SIP (Sterilising In Place)
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/SIP is therefore a cleaning and sanitisation activity of the plant of which the LDPU is an integral part and therefore in turn affected by it.
ATTENTION
Before carrying out CIP/SIP 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/SIP, 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/SIP,
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/SIP, activate operation of the same LDPU.
