1.4 Hazardous liquids or gases in the pipeline
Consider what is in the pipeline or what may have been in the pipeline
at some previous time. Consider: flammable materials, substances
hazardous to health, extremes of temperature.
1.5
Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases, extremes of temperature, hot surfaces, fire hazard (e.g.
during welding), excessive noise, moving machinery.
Hazardous environment around the product
1.6 The system
Consider the effect on the complete system of the work proposed. Will
any proposed action (e.g. closing isolation valves, electrical isolation)
put any other part of the system or any personnel at risk?
Dangers might include isolation of vents or protective devices or the
rendering ineffective of controls or alarms. Ensure isolation valves are
turned on and off in a gradual way to avoid system shocks.
1.7
Ensure that any pressure is isolated and safely vented to atmospheric
pressure. Consider double isolation (double block and bleed) and the
locking or labeling of closed valves. Do not assume that the system has
depressurized even when the pressure gauge indicates zero.
Pressure systems
1.11
All work must be carried out or be supervised by a suitably
competent person.
Installation and operating personnel should be trained in the correct
use of the product according to the Installation and Maintenance
Instructions.
Where a formal ‘permit to work’ system is in force it must be complied
with. Where there is no such system, it is recommended that a responsible person should know what work is going on and, where necessary,
arrange to have an assistant whose primary responsibility is safety.
Post ‘warning notices’ if necessary.
Permits to work
1.12 Handling
Manual handling of large and/or heavy products may present a risk of
injury. Lifting, pushing, pulling, carrying or supporting a load by bodily
force can cause injury particularly to the back. You are advised to
assess the risks taking into account the task, the individual, the load
and the working environment and use the appropriate handling method
depending on the circumstances of the work being done.
1.13 Residual hazards
In normal use the external surface of the product may be very hot. If
used at the maximum permitted operating conditions the surface tem
perature of some products may reach temperatures of 662°F (350°C ).
Many products are not self-draining. Take due care when dismantling
or removing the product from an installation (refer to ‘Maintenance
instructions’).

1.8 Temperature
To avoid burns, it is essential that cooling water is flowing before opening the sample inlet valve. Always close the sample inlet valve before
turning off the cooling water.
1.9 Tools and consumables
Before starting work ensure that you have suitable tools and/or consumables available. Use only genuine Spirax Sarco replacement parts.
1.10 Protective clothing
Consider whether you and/or others in the vicinity require any protective clothing to protect against the hazards of, for example, chemicals,
high/low temperature, radiation, noise, falling objects, and dangers to
eyes and face.
2. General product information
2.1 Description
The Spirax Sarco SSC20 sanitary sample cooler has been specifically
designed for taking high quality chemical, conductivity and microbiological samples quickly and safely from clean/pure steam, water for
injection (WFI) and other high purity media systems.
The unit consists of high quality 316L stainless steel components and
utilizes a counter current flow to maximize cooler efficiency, resulting in
a compact, space saving design.
1.14 Freezing
Provision must be made to protect products which are not self-draining
against frost damage in environments where they may be exposed to
temperatures below freezing point.
1.15 Disposal
Unless otherwise stated in the Installation and Maintenance
Instructions, this product is recyclable and no ecological hazard is
anticipated with its disposal providing due care is taken.
1.16 Returning products
Customers and stockists are reminded that under EC Health, Safety
and Environment Law, when returning products to Spirax Sarco they
must provide information on any hazards and the precautions to be
taken due to contamination residues or mechanical damage which may
present a health, safety or environmental risk. This information must be

3. Installation
Note: Before actioning any installation observe the ‘Safety information’ in Section 1.
- We recommend the use of corrosion resistant pipework suitable for
the fluid being sampled.
- Keep the length of all pipes to a minimum.
- Cooling water must be clean and free of scale forming salts.
- The sample cooler must be mounted vertically, using the
pre-drilled top and bottom mounting brackets (see Fig. 3).
- Allow sufficient space below the SSC20 for collection of the
sample in a beaker or similar container. We recommend that a
tundish piped to drain is located underneath this outlet.
No connection is required on the sample OUT.
- Connect the pipework as shown in the drawing. The cooling water
IN should be piped to the bottom of the sample cooler in 1/2"
nominal bore pipe via a cooling water inlet valve.
A 1/2" BSP/NPT male/female elbow makes a suitable connector.
- Pipe the cooling water OUT from the top of the sample cooler to an
open drain or tundish.
Caution: to avoid the possibility of an air lock at the top of the
sample cooler, do not allow the thread of the cooling water OUT
elbow to protrude into the sample cooler body - maximum
thread engagement 15 mm.
- Install the clamp fitting and seal in accordance with the
manufacturer’s instructions.

4. Commissioning
After installation or maintenance carry out tests to ensure that the system is fully functional.
5. Operation
Warning:-
To avoid the risk of scalding, it is essential that a full flow of
cooling water is present before opening the sample inlet valve.
Always close the sample inlet valve before turning off the cooling
water.
Sample pipework becomes very hot under normal working
conditions, and will cause burns if touched.
Follow this procedure for safe operation and accurate sampling:-
- Open the cooling water inlet valve first and ensure that a full flow
can be seen at the cooling water outlet.
6. Maintenance
No routine maitenance is required.
7. Spare parts
The following components are available as spares:
Component Stock no.
Stud coupling stainless steel BSP 0963243
- Gradually open the sample inlet valve and regulate the flow to
achieve a cooled sample at about 77°F (25°C).
- Allow the sample to run for a while before collection. This will
ensure that a true sample is collected for analysis.
- When enough liquid has been collected close the sample inlet first,
and then the cooling water inlet valve.
- After closing the sample inlet valve the sample OUT connection
may drip for a few minutes while the coil drains.
