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 high pressure or city water system.
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, and system accessories before testing.
• Release all air in system before testing.
• Tighten Sta-Rite 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 104o F. (40o C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready
for operation. Remove trap lid and retighten hand tight only.
NOTICE: These parameters apply to Sta-Rite equipment only. For
non-Sta-Rite equipment, consult manufacturer.
BEFORE WORKING
ON FILTER:
Hazardous pressure.
Can cause severe
injury or major
property damage from
tank blow up.
1. Stop pump.
2. Open air release
valve.
3. Release all pressure
from system.
BEFORE WORKING
ON PUMP OR MOTOR
Filter pumps require
hazardous voltage
which can shock,
burn, or cause death.
3
Disconnect power to
motor.
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 diatomaceous earth (DE) filter system 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.
DO NOT use more than the recommended amount of DE in your filter. To do
so can cause a buildup of DE and "bridging" between the elements which will
plug the filter.
If filter is improperly disassembled or assembled, it can explode under
pressure! To avoid danger of severe injury or major property damage,
always follow service instructions in this manual when working on filter!
Hazardous pressure.
Can cause severe
injury or major
property damage
from tank blow up.
Release all pressure
and read instructions
before working on filter.
NEVER operate this filter system at more than 50 pounds per square
inch (50 PSI/345kPa) pressure! Be sure filter pressure gauge operates
when system is operating. If pressure gauge is damaged or does not
work, replace it.
Purge all air from system before operating system. NEVER operate filter
with air trapped inside.
On a new pool installation, we recommend:
1. Disassemble the filter after the initial cleanup.
To prevent severe injury or major property damage, exactly follow "Filter
Disassembly/Assembly Procedure" on page 8.
2. Remove and hose down the element assembly to remove contaminants.
It is a good idea to remove the element assembly once a year and soak it in a
filter cleaning solution to remove accumulated body oils, etc.; see Page 11,
"Chemical Cleaning Procedure".
Cleaning interval is based on pressure differential, not on length of time filter
is operated. Different water conditions will have different normal cleaning intervals. If backwashing filter is not possible, use "Manual Filter Cleaning
Procedure", Page 10, at regular intervals to clean filter.
Check local codes for restrictions on backwash to waste piping, separation
tank requirements and spent D.E. disposal requirements.

INSTALLATION
Installation of filter should only be done by qualified, licensed personnel.
Filter mount must:
Provide weather and freezing protection.
Provide space and lighting for easy access for routine maintenance. (See
Figure 1 and Table II, Page 6, for space requirements.)
Be on a reasonably level surface and provide adequate drainage.
Be as close to pool as possible to reduce line loss from pipe friction.
Piping:
Piping must conform to local/state plumbing and sanitary codes.
Use Teflon tape or Plasto-Joint Stik' on all male connections of plastic pipe
and fittings. DO NOT use pipe compounds on plastic pipe; it will cause the
pipe to crack. Do not use sealant on unions—assemble them dry and hand
tight.
Support pipe independently to prevent strains on filter or valve.
Use 1-1/2" (38mm) or 2” (51mm) pipe to reduce pressure losses as much as
possible.
TABLE I - Sta-Rite valves for
use with DEPB filters
NOTICE: Filter may be located away from pool, but for adequate flow larger
pipe may be needed. Check local codes for remote installation.
Fittings restrict flow; for best efficiency use fewest possible fittings.
Keep piping tight and free of leaks: pump suction line leaks may cause
trapped air in filter tank or loss of prime at pump; pump discharge line leaks
may show up as dampness or jets of water.

Install Sta-Rite Two Position Slide Valve or Multiport Selector Valve with filter.
See Table I.
Filter ports and valve ports are furnished with union connections.
DO NOT use pipe sealants on union collar (nut).
NOTICE: Use of valves
other than those listed
above could cause
reversed water flow
through filters and
damage to internal filter components.
Use care before assembly not to damage union sealing surfaces or O Ring.
To allow recirculation during precoat (if precoat pot is used), install a recirculation line with shut-off between pad return line and pump suction.
Electrical
All wiring, grounding and bonding of associated equipment must meet local
and/or National Electrical Code standards.

A. Record filter operating pressure at startup. When pressure reaches 15
PSI (103kPa) above startup operation pressure, stop pump for 15-30
seconds to allow filtering cake to release.
B. Restart pump to form new cake. Pressure should now be less than 10
PSI (69kPa) above startup operating pressure.
C. If pressure is still more than 10 PSI (69kPa) above startup operating
pressure, backwash filter (see below).
2. Thoroughly clean air relief filter screen (Key No. 2, Page 13) on top of
manifold EVERY time filter is opened. Be sure to remove all debris from
screen. Replace filter screen if damaged.
3. At least twice a year, manually clean filter according to instructions, Page
10. At least once a year, follow instructions under "Chemical Filter
Cleaning Procedure", page 11, as well.

NOTICE: Time between backwashes will vary with
each installation and between different areas of the
country. The following causes and remedies are for
cycle times shorter than normal for your area.
C. Piping too small; use larger pipe (consult dealer
for sizing).
D. Filter area too small; install larger filter or auxiliary filter (consult dealer for recommendation)
3. Low Flow/Low Pressure:
A. Pump too small; consult dealer for recommendations.
B. Plugged pump or plugged hair and lint trap; clean
thoroughly.
A. Chlorine residual too low; maintain proper residual (consult pool professional for recommendation).
B. Flow rate too high; restrict flow to rated capacity
of filter (see instruction plate on filter or specifications on Page 6).
4. Plugged Grid Cloth:
A. Insufficient precoat; see precoat instructions (Page
7).
B. Insufficient cleaning; follow cleaning instructions
closely and clean thoroughly (see Pages 9-11).
