CHEMICAL SYSTEM RESPONSABILITY
DISCLAIMER
The following policy should be considered and understood as a warranty/disclaimer to
customers operating textile care installations where liquid supply (chemical) systems use or
may use peristaltic pumps to inject supplies into equipment.
To Whom it May Concern :
We, the undersigned, accept no responsibility for loss or damage when, during periods of
non-use, concentrated chemicals leak, spray or "dribble" onto any part of our machines or their
contents.
It is well known that many pumped liquid chemical systems tend to permit concentrated
chemicals to dribble out of the injection tubes when the system has not been used for
relatively long periods of time – as after working hours and during weekends. This puts highly
concentrated corrosive chemicals in direct contact with dry stainless steel surfaces and often
directly on any textiles left in the machine. Chemical deterioration (rusting) of the stainless steel
and damage to the textiles is the inevitable result.
It is absolutely useless to fl ush the affected sites after each injection because the harmful
dribble always occurs later – after the machine is no longer in use. One seemingly foolproof
solution for "dribbling chemicals" (which we highly recommend but obviously cannot guarantee)
is to locate the chemical tanks and pumps well below the injection point on the machine (so
the contents of the injection tube(s) cannot siphon into the machine) and to completely purge
the just-used chemical injection tube(s), or manifold, with fresh water after every injection so
that only fresh water (which cannot cause a problem) can dribble out. Naturally, this – or any
other solution – is the sole responsibility of the pump and/or chemical supplier (not the machine
manufacturer).
Additionally, external chemical leakage is dangerous to personal health and safety, and will
also cause severe damage to machines and/or their surroundings. The installer and/or user
of the chemical injection system must make sure there are no external chemical leaks and
that excessive pressure can never build up in any chemical delivery tube, because excessive
pressure can burst the tube, or disconnect it from the machine, and spray dangerous
concentrated chemicals about the premises.
The machinery manufacturer is not, and cannot be, responsible for compliance with the above.
