HI-FLOW™ Side Mounted Backwash Valve Installation and User's Guide

FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s), etc.), is serviced, air can enter the
system and become pressurized. Pressurized air can cause the lid to separate which can result in severe injury,
death, or property damage. To avoid this potential hazard, follow these instructions:
1. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of
the clamp or any other service of the circulating system: (A) Turn the pump
OFF
and
shut OFF
any
automatic controls to ensure the system is NOT inadvertently started during the servicing; (B) open the
manual air relief valve; (C) wait until all pressure is relieved.
2. Whenever installing the filter clamp
FOLLOW THE
FILTER CLAMP INSTALLATION INSTRUCTIONS
EXACTLY
.
3. Once service on the circulating system is complete
FOLLOW SYSTEM RESTART INSTRUCTIONS
EXACTLY
.
4. Maintain circulation system properly. Replace worn or damaged parts immediately, [e.g., clamp,
pressure gauge, valve(s), o-rings, etc].
5. Be sure that the filter is properly mounted and positioned according to instructions provided.
