Installation and System Testing

Products should be kept clean and undamaged before use.

All installations must be pressure tested after installation to ensure system

integrity before handing over to the final user. See also “Making a connection”.


Cleaners and Sanitising of Acetal Fittings.


The external surfaces of Apex Filtamate products must not come into contact

with oxidising or acidic cleaners and sanitising agents, for example (but not

limited to) those below pH 4, high in sodium hypochlorite level (bleach) or

containing hydrogen peroxide. Our plastic material suppliers recommend

ECOLAB Oasis 133 as a suitable cleaner for the external surfaces of acetal

products manufactured by Apex Filtamate.


Several different methods exist for sanitising the internal surfaces of fluid

systems, including sodium hypochlorite, hydrogen peroxide, chlorine dioxide

or ozone. It is entirely the responsibility of the end user to determine if the

chosen method is suitable for use with John Guest products over the planned

working life of the system. However, to avoid unnecessary early failure, John

Guest requires that the disinfection solution must be immediately flushed outat all draw off points with fresh, wholesome water at the end of the disinfectionperiod. The solution must not be left in the system. Disinfection solutionsmust only come into contact with the internal (fluid carrying) surfaces of thesystem. If any other surfaces of a fitting come into contact with disinfectionsolution, the whole fitting must be replaced immediately.Details of whichproducts are made from Acetal are shown in our catalogues but generally Polypropylene fittings offer greater resistance

to aggressive chemicals than Acetal fittings. Polypropylene does not have the

same mechanical properties as Acetal.


Product Design


Apex Filtamate Valves has a policy of continuous research and development and reserves the right to amend without notice the specification and design of all products. Product descriptions and sizes are approximate and Apex Filtamate reserves the right to supply products which may have minor and negligible deviations from that printed in catalogues etc. (or from products previously supplied).



Whilst we give a warranty against defects in manufacture or materials, it is

are suitable for their application. The installation must be carried out correctlyin accordance with our recommendations, complying with recognised codesof practice and relevant national standards, and be properly maintained.

Side Loads


Apex Filtamate products are not designed to be used under side load as this

may adversely affect their ability to function long-term. Always ensure tubes

have good alignment with the fitting. They must also not be subjected to any

form of impact or other damage, such as being hit or dropped, even

accidently. If fittings have damaged or suffered an impact, they should be

replaced immediately. Apex Filtamate warranty does not cover loss caused by any form  of  damage
