General safety, installation and maintenance guidelines
WARNING
As with all pressurised systems, do not attempt any installation or maintenance
function if there is any pressure in the product or connected system.
Spirax-Monnier
Spirax-Monnier compressed air products are of well proven and simple design, with high natural
levels of designed safety built-in. However, used or installed incorrectly, their performance and
that of the system they are protecting or controlling, may suffer. The information given in this
document indicates the product limiting conditions, maintenance and installation requirements
and any specific component disposal needs (see Table opposite).
Note
Customers are reminded that under UK and EC Health, Safety and Environmental 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
provided in writing including Health and Safety data sheets relating to any substances
identified as hazardous.
Installation and operation
1.
Filters, filter / regulators, lubricators, flowmeters, separators and drain traps should be
fitted in horizontal pipelines, with the bowls vertically downwards.
2.
Regulators and ball valves can be installed in any position.
3.
On pressure regulators and combined filter / regulators, a pressure gauge can be connected
to one of the
1
/
8
" ports. The gauge should be selected to cover the maximum pressure range
of the main control spring. The gauge will indicate the downstream or controlled pressure.
4.
Ensure that the control spring range for regulators and filter / regulators fully meets the
pressure requirements of the system.
5.
There are maximum operating pressures, and maximum operating and environmental
temperatures for each product. These are shown in the Table opposite.
6.
Adequate space should be provided around any product to allow easy access for routine
servicing requirements.
7.
Products fitted with a bowl (polycarbonate or metal ) should be adequately drained - manually
or automatically - to reduce the potentially harmful effects of water carryover.
8.
WARNING Polycarbonate bowls and sight domes, and sight levels fitted to metal bowls,
may be attacked by phosphate ester based fluids, solvents, chemical cleaners, carbon
tetrachloride, etc. These and other similar substances should never be allowed to come into
contact with these product components. Certain compressor lubricating oils also contain
additives harmful to these components. Where there is any doubt, we recommend, in the
interests of safety, that bowl guards or metal bowls are fitted.
9.
Local regulations may restrict the use of this product below the conditions quoted.
