CHLORINE FEEDERS
IMPORTANT DISCLAIMER
Material selections such as Viton and Hastelloy c-276 ensure that FlowVis® will provide many years of trouble-free
operation in normally treated, sanitized pool water conditions. However, certain brands and designs of inexpensive
chlorine feeders are known to fail and release high concentrations of chlorine or even chlorine gas into the
surrounding filtration system. When this occurs, any equipment that comes into contact with these abnormal levels
of chemicals will experience rapid and catastrophic damage. Inspection of any failed components will quickly and
conclusively confirm the cause of the damage and, under these circumstances, the product's warranty will be void.
Under no circumstances should FlowVis® be used as a 'check valve' to prevent the effects of these Chlorine Feeders
damaging other equipment such as Heaters.
TIGHTENING LID SCREWS
When removing and re-installing the FlowVis® lid assembly, it is important to adhere to the following procedure:
1.
Make sure that the o-ring on the underside of the lid is undamaged, lubricated with silicone (such as Boss 820)
and is in-place without twists.
2. Ensure flapper hinge pin is centered.
3. Carefully lower the lid onto its valve body (or Tee in the case of the DN80
and DN100 models), making sure that the o-ring stays in place.
4. Insert by hand the (8) stainless steel screws but do not tighten at this
stage.
5. Using a hand Phillips-head screwdriver, slowly tighten the screws in a
diagonal pattern, per the sequence to the right. Do not fully tighten one
screw before proceeding to the next, i.e., pull them down slowly multiple
times to avoid stressing and cracking the lid. Screws should be tightened
to a final torque of 34 Nm.
