SECTION II. FILTER INSTALLATION.
A. GENERAL INFORMATION
1. New pools have a tremendous amount of debris due to dirt in the lines, plaster dust, etc. This debris will be removed
by the filter and will require daily backwashing of the filter until it is removed. Check the pressure gauge daily and
backwash the filter when the pressure increases 8 - 10 psi over the initial reading. It will require several
backwashings before the pool is clean. Thereafter, the normal filter cycle will be several weeks in a properly
designed system. The filter cycle is lengthened or shortened by contamination loads.
2. When installing backwash lines, it is recommended to install a vacuum breaker where the backwash line is over 40
feet long, or if the line discharges 10 feet or more lower than the water level of the pool. Operating at excessive
vacuum levels can cause the tank to implode, which voids the warranty.
3. A check valve is recommended between the filter and heater to prevent hot water backup from damaging the filter
internals.
4. The maximum operating pressure of the tank is 50 psi. Never operate the unit above this pressure or attach a pump
to this filter that has a shut off pressure higher than 50 psi.
5. Never install a chemical feeder or ozonator upstream of the filter. Always locate downstream with a check valve
between the feeder and the filter.
6. A positive shut off valve is not recommended downstream of the filter and/or heater. If the system is ever run with
such a valve closed, the internal air vent becomes inoperative and an explosive situation could exist. Running the
system with no flow can seriously damage the equipment.
7. Clean your filter when pressure reads between 8-10 psi higher than the original starting pressure. Your filter pressure
reading will increase as it removes dirt from your pool. However, this buildup of pressure will vary due to different
bathing loads, temperature, weather conditions, etc.
a. MY ORIGINAL STARTING PRESSURE IS ___________ psi (pounds per square inch). I SHOULD BACKWASH
(CLEAN) THE FILTER AT __________ psi.
8. Check carton for any evidence of damage due to rough handling in shipment. If carton or any filter components are
damaged, notify freight carrier immediately.
9. The filter should be mounted on a level concrete slab. Position the filter so that instructions, warnings and the
pressure gauge are visible to the operator. It also should be positioned so that the piping connections, control valve
and drain port are convenient and accessible for servicing and winterizing.
THIS 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 BE BLOWN OFF 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 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.
