Pentair Clean & Clear Plus Cartridge Filter - Manual (Page 3)

REV. J 6-27-03 3 P/N 178558
If doubt exists as to the pressure to which the system will be subjected, install an ASME
approved automatic Pressure Relief or Pressure Regulator in the circulation system for the
lowest working pressure of any of the components in the system.
SECTION II. FILTER OPERATION AND CLEANING
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE
CIRCULATING SYSTEM (e.g., FILTER LID, PUMP, FILTER, VALVES, ETC.) IS SERVICED,
AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN
CAUSE THE LID TO BLOW OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR
PROPERTY DAMAGE. TO AVOID THIS POTENTIAL HAZARD, FOLLOW THESE
INSTRUCTIONS.
1. BEFORE REPOSITIONING VALVES AND BEFORE BEGINNING THE ASSEMBLY,
DISASSEMBLY, OR ADJUSTMENT OF THE LID OR ANY OTHER SERVICE OF THE
CIRCULATING SYSTEM: (A) TURN THE PUMP OFF AND SHUT OFF ANY AUTOMATIC
CONTROLS TO ASSURE THE SYSTEM IS NOT INADVERTENTLY STARTED DURING
THE SERVICING. (B) OPEN AIR RELIEF VALVE, AND (C) WAIT UNTIL ALL PRESSURE
IS RELIEVED - PRESSURE GAUGE MUST READ ZERO (0 psi).
2. WHENEVER INSTALLING THE FILTER LID, FOLLOW THE FILTER LID 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., lid, knob, pressure gauge, relief valve, O-rings, etc.)
5. BE SURE THAT THE FILTER IS PROPERLY MOUNTED AND POSITIONED ACCORDING
TO INSTRUCTIONS PROVIDED.
WARNING
A. GENERAL INFORMATION
1. This filter operates under pressure. When clamped properly and operated without air in the
circulating system, this filter will operate in a safe manner.
2. The maximum working pressure of this filter is 50 p.s.i. Never subject this filter to pressure in
excess of this amount - even when conducting hydrostatic pressure tests. Pressures above 50 p.s.i.
can cause the lid to be blown off, which can result in severe injury, death or property damage.
When performing hydrostatic pressure tests or when testing for external leaks of the
completed filtration and plumbing system, insure that the MAXIMUM PRESSURE that the
filtration system will be subjected to DOES NOT EXCEED THE MAXIMUM WORKING
PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN THE SYSTEM. In
most cases, the maximum pressure will be stated on each component of the system.
If doubt exists as to the pressure to which the system will be subjected, install an ASME
approved automatic Pressure Relief or Pressure Regulator in the circulation system for the
lowest working pressure of any of the components in the system.
