READ AND FOLLOW SAFETY
INSTRUCTIONS!

This is the safety alert symbol. When you see this symbol on your filter or in
this manual, look for one of the following signal words and be alert to the

potential for personal injury.

WARNING

Hazardous Pressure!

Can cause tank
explosion.

Do not connect filter to
compressed air under any
circumstances.

warns about hazards that will cause death, serious personal injury,

or major property damage if ignored.

warns about hazards that can cause death, serious personal injury,

or major property damage if ignored.

warns about hazards that will or can cause minor personal injury or

property damage if ignored.
NOTICE indicates special instructions not related to hazards.
Carefully read and follow all safety instructions in this manual and on equipment.

Keep safety labels in good condition; replace if missing or damaged.

Incorrectly installed or tested equipment may fail, causing
severe injury or property damage. Read and follow instructions in
owner's manual when installing and operating equipment. Have a
trained pool professional perform all pressure tests.

1. Do not connect system to a city water system or other external source of
pressurized water.

2. Use equipment only in a pool or spa installation.

3. Trapped air in system can cause explosion. BE SURE all air is out of system
before operating or testing equipment.

Before pressure testing, make the following safety checks:

• Check all clamps, bolts, lids, lock rings and system accessories before testing.

• Release all air in system before testing.

• Tighten Sta-Rite pump trap lids to 30 ft. lbs. (4.1 kg-cm) torque for testing.

• Water pressure for test must be less than 25 PSI (172 kPa).

• Water Temperature for test must be less than 100

• Limit test to 24 hours. After test, visually check system to be sure it is ready for
operation. Remove pump trap lid and retighten hand tight only.
NOTICE: These parameters apply to Sta-Rite equipment only. For
non-Sta-Rite equipment, consult equipment manufacturer.

When to Clean the Filter

The filter module should normally be
cleaned when the pressure gauge
reading increases 10 PSI over the start­up pressure (record the start-up
pressure under “Owner’s Information”,
below, right).

In some pools, accessories such as
fountains or pool cleaners may be
noticeably affected by the normal
decrease in flow as the filter becomes
dirty. If so, clean the filter more
frequently (that is, at a pressure increase
of less than 10 PSI) in order to maintain
the required flow.

GENERAL INFORMATION

• Clean a new pool as well as possible before filling pool and operating
filter. Excess dirt and large particles of foreign matter in the system can
cause serious damage to the filter and pump.

• With a permanent media filter in place and operating correctly, clean water
is returned to the pool faster than pool water is being contaminated. A
typical pool installation will require approximately one week to obtain and
maintain the sparkle that your filter is capable of giving you.

• Maximum pressure is 50 PSI (345 kPa). DO NOT connect the filter to a
city water system or to an individual water well system.

Hazardous pressure. Open air release valve to vent all air
from system before operating system. NEVER operate filter with air
trapped inside.

• The Sta-Rite
pools and spas. On a new installation, we recommend:

1. Disassemble the filter after the initial cleanup.

property damage, exactly follow "Filter Disassembly/Assembly
Procedure" on Pages 6 and 7.

2. Remove and hose down the element assembly to remove contaminants.

• Maintain pool water pH between 7.2 and 7.6.

• Make sure that internal air bleed tube and filter are clean and installed
properly at top of module before operating filter.

• Make sure that Posi-Lok™ Ring is securely locked in place before
operating filter.

• Maintain pressure gauge in good working order. Replace a damaged
gauge immediately.

• Cleaning interval is based on pressure rise, not on length of time filter is
operated. Different water conditions will have different normal cleaning
intervals.

• Check local codes for restrictions on waste water disposal requirements.
NOTICE: Some pool disinfectants may clog filter module. To maximize

module life and filter cycle time, closely follow disinfectant manufacturer’s
instructions when cleaning pool or filter. Failure to follow these instructions
may affect warranty coverage of the module.
