COTSWOLD CLUSTER FLUSH
Milking Cluster Disinfection System
FOR SWING OVER PARLOURS
Model 220
PRODUCT MANUFACTURING, SERVICING & MAINTENANCE OVERVIEW
The Cotswold Cluster Flush is a system for the effective removal of infectious
material left in the milking cluster after a cow has been milked, so that the cluster
is disinfected before it is used to milk another cow.
The system mixes a small amount of recommended disinfectant with a pre-
determined amount of water, and automatically “flushes” each milking cluster with
this mixture. This process is repeated after every cow is milked.
Using the Cluster Flush System leads to a substantial reduction in the risk of
cross-infection between cows in the dairy.
SERVICES
The system is mains-powered (230v 50/60hz 1amp). At the point of use the
operating voltage is reduced to 24v dc.
The system requires a ready supply of fresh clean water and a clean compressed-
air supply (at 2 bar).
WIRING:
Connect the Power Supply Unit (PSU) to the mains via a double-pole isolation
switch, which should be visible and within easy reach of system operators.
Wiring from the power supply to each control box should be SELV, using a suitable
type of wire like H03VVF with a CSA of at least 0.75mm2.
All controllers and the power supply unit must be suitably earthed.
All connector tags and terminals will be zinc plated.
This equipment is rated for OV (over-voltage) Category 2 supplies.
PRESSURE VESSEL SPECIFICATION AND USAGE
The pressure cylinder is SEP-rated category-1 at its 2 bar mandatory operating
pressure. Its maximum safe pressure rating is 6 bar.
ENVIRONMENTAL CONDITIONS:
The system can be installed in milking parlours anywhere on the planet. Do not
use in the open, in direct sunlight or where pipework could be subject to freezing.
The protection offered by this product may be impaired or lost if installation and
maintenance is not carried out in line with the instructions in this manual.
LABELING
All labels used in this product comply with the CE Water and Hexane Rub Test. 3
CLUSTER FLUSH – PRODUCTION, SERVICING & MAINTENANCE
SAFETY INSTRUCTIONS –
(COMPLETE SYSTEM INCLUDING PRESSURE COMPONENTS)
(The Cotswold Cluster Flush – an SEP category 1 product)
These instructions relate primarily to factory manufacturing procedures, but since the
Cluster Flush needs regular onsite service and maintenance, we include them here too.
Component Preparation
All forming, bending drilling chamfering or any other working of
components must not cause changes in the mechanical characteristics of
those components and in no way reduce their efficiency.
Permanent joints in pressurised segments
For Cluster Flush pressure equipment (pressure cylinders), permanent
joining of components which contribute to their pressure resistance - and
components which are directly attached to them - must be carried out by
suitably trained personnel.
Permanent Joints and their adjacent zones must be free of any surface or
internal defects that could be detrimental to the safety of the equipment.
Permanent joints must always meet the minimum properties specified for
the materials to be joined.
Traceability
Inner pressure cylinders must be permanently labelled to show operating
pressure and year of manufacture.
Use label: (Pressure-Vessel (Sep-Category-1) , also label: (S Ayling materials
and date of moulding).
Final Testing
Pressure equipment must be subjected to final testing and inspection. A
test and inspection of the completed power supply unit and every control
panel/pressure cylinder assembly is essential.

INSTALLATION NOTES
(DOUBLE-UP PARLOUR HIGH LEVEL)
ORDER OF INSTALLATION
!For ease of installation, we recommend the following installation sequence:
! 1/ HEADER TANKS
2/ WATER / PLUMBING
3/ SET UP WATER CYLINDERS
4/ INSTALL AIRLINES
5/ CONTROLLERS and ELECTRICAL
WATER / CHEMICAL
Site the Header Tank at the same level as the cylinders. Ensure that the water level in the cylinders is
set 50mm (2 inches) below the top of the stainless tube, (see schematic drawings attached).
Run 2 inch (50mm) water tube from each header tank along the centre of the parlour, connecting to
each cylinder using tees, taps and 110x16mm i/d tube. At the lowest point fit a reversed (upside-
down) tee/tap so that it can be used as a drain point if required.
Chemical Dosing
We can supply Dosatron high accuracy dosing units if required. When dealing with chemicals, do
take all recommended precautions. Before commissioning the system, ensure all unions are tight
and the clusters hang correctly
AIR 2 - 3 bar, (pressure reducer may be required)
Connect the airline to the centre of the line of milking points, and Tee out to either side. Use 22mm
Flexible Tubing between the compressor (clean air filters should be fitted) and the centre
22x22x10mm tee.
Anti Syphon Valves, fit one valve either side of Tee connection of air line, at the mid point of each half
(see schematics)
Pressure Reducer
We can supply suitable pressure reducing valves if required.
ELECTRICAL
Locate Power Supply Unit (PSU) in a safe dry location, run 24v supply to the dual-solenoid control box.
If your system is Manually Triggered (by green Thumb-Switches in a grey boxes) locate convenient
positions for these and install them.
Also Arrange a convenient switch to turn off the system when it is not in use.
Always switch off system when washing parlour.
CONNECTION TO MILK LINE
Cut into the milk line and and fit the “Y” piece moulding using 13mm pvc tubing connecting to upper
horizontal outlet of stainless steel cylinder.
SHUT-OFF VALVE
(for Cluster Flush)
Controls maximum of two (2) cluster
points on either side of valve
(see schematic drawings for detail)
