later sections. Throughout the manual, safety warnings and cautions are identified by the “ “ symbol. Be sure to read
and comply with all of the warnings and cautions.
THIS FILTER OPERATES UNDER HIGH PRESSURE
When any part of the circulating system, (e.g., closure, pump, filter, valve(s), etc.), is serviced, air can
enter the system and become pressurized. Pressurized air can cause the top closure to separate
which can result in severe injury, death, or property damage. To avoid this potential hazard, follow
these instructions:
1. If you are not familiar with your pool filtering system and/or heater:
a. Do NOT attempt to adjust or service without consulting your dealer, or a qualified pool
technician.
b. Read the entire Installation & User’s Guide before attempting to use, service or adjust the
pool filtering system or heater.
2. Before repositioning valve(s) and before beginning the assembly, disassembly, 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 bleeder valve; (C) wait until all pressure is relieved.
3. Whenever installing the filter closure FOLLOW THE FILTER CLOSURE WARNINGS EXACTLY.
4. Once service on the circulating system is complete FOLLOW INITIAL START-UP
INSTRUCTIONS EXACTLY.
5. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g.,
closure, pressure gauge, valve(s), o-rings, etc).
6. Be sure that the filter is properly mounted and positioned according to instructions provided.

IMPORTANT WARNING AND SAFETY INSTRUCTIONS
This filter must be installed by a licensed or certified electrician or a qualified pool serviceman
in accordance with the National Electrical Code and all applicable local codes and ordinances.
Improper installation could result in death or serious injury to pool users, installers, or others and
may also cause damage to property.
Always disconnect power to the pool circulating system at the circuit breaker before servicing the
filter. Ensure that the disconnected circuit is locked out or properly tagged so that it cannot be
switched on while you are working on the filter. Failure to do so could result in serious injury or
death to serviceman, pool users or others due to electric shock.
Do not operate the filter until you have read and understand clearly all the operating
instructions and warning messages for all equipment that is a part of the pool circulating
system. The following instructions are intended as a guide for initially operating the filter
in a general pool installation. Failure to follow all operating instructions and warning
messages can result in property damage or severe personal injury or death.
To reduce the risk of injury, do not permit children to use this product unless they are
closely supervised at all times.
Due to the potential risk that can be involved it is recommended that the pressure test be
kept to the minimum time required by the local code. Do not allow people to work around
the system when the circulation system is under pressure test. Post appropriate warning
signs and establish a barrier around the pressurized equipment. If the equipment is located
in an equipment room, lock the door and post a warning sign.
Never attempt to adjust any closures or lids or attempt to remove or tighten bolts when the
system is pressurized. These actions can cause the closure to separate and could cause
severe personal injury or death if they were to strike a person.
Never exceed the maximum operating pressure of the system components. Exceeding
these limits could result in a component failing under pressure. This instantaneous release
of energy can cause the closure to separate and could cause severe personal injury or
death if they were to strike a person.

INSTALLATION
NOTE: Before installing this product, read and follow all warning notices and instructions starting on page ii.
Installing theTriton®Fiberglass Sand Filter
Only a qualified service person should install the Triton filter.This filter is designed and intended for use
to filter water.
Introduction
The following general information describes how to install the Triton Fiberglass Sand Filter.This filter
operates under pressure and if assembled improperly or operated with air in the water circulation
system, the top closure can separate and result in an accident causing property damage or serious
bodily injury. A warning label has been affixed to the top of the filter and should not be removed.Keep
safety labels in good condition and replace if missing or illegible.
How the FilterWorks
The high rate sand filter is designed to operate for years with a minimum of maintenance and when
installed,operatedand maintainedin accordancewith these instructions, it will provideyearsof trouble
free operation.
Dirt is collected in the filter as the water flows through the control valve at the side of the filter and is
directed into the top bulkhead.Dirty water flows into the diffuser at the top of the tank and is directed
downward into the top surface of the filter sand bed.The dirt is collected in the sand bed and the clean
water flows through the laterals and lower piping at the bottom of the filter up into the lower bulkhead.
The flow then goes into the control valve at the side of the filter. Clean water is returned through the
piping system into the pool.
Thepressurewillriseandtheflowtothepoolwillbeloweredasthedirtiscollectedinthefilter.Eventually,
the filter will become so plugged with dirt that it will be necessary to perform the backwash procedure. It
isimportanttoknowwhentobackwashthefilter.Backwashingisdiscussedfurtherunder the subsequent
sections of this guide.
Please note that a filter removes suspended matter and does not sanitize the pool. The pool water
must be sanitized and the water must be chemically balanced for sparkling clear water.Your filtration
system should be designed to meet your local health codes. As a minimum, you must be sure that
your system will turn over the total volume of water in your pool at least two to four times in a twenty-
four hour period.
Refer to Table 1 for Filter Operation Data.

TRITON®Fiberglass Sand Filter Installation and User’s Guide
Failure to operate your filter system or inadequate filtration can cause poor water clarity obstructing
visibility in your pool and can allow diving into or on top of obscured objects which can cause serious
personal injury or drowning.
Clear water is the result of proper filtration as well as proper water chemistry. Pool chemistry is a
specializedareaandyoushouldconsult yourlocal pool servicespecialist forspecificdetails.Ingeneral,
proper pool sanitation requires a free chlorine level of 1 to 3 PPM and a pH range of 7.2 to 7.6.
Filters should never be tested or subjected to air or gas under pressure. All gases are compressible
and under pressure create a danger. Severe bodily injury or property damage could occur if the filter is
subjected to air or gas pressure.
1. Check carton for any evidence of damage due to rough handling in shipment.If carton or any filter
components are damaged, notify the freight carrier immediately.
2. Carefully remove the accessory package and the filter tank from the carton.
3. Mountthefilteronapermanentslab,preferablyconcretepouredinaformoronaplatformconstructed
of concrete block or brick.DO NOT use sand to level the filter or for the pump mounting, as it will
wash away.
4. Provide space and lighting for routine maintenance access. Do not mount electrical controls over
the filter.One needs to be able to stand clear of the filter when starting the pump.Minimum space
requirements may be found on the large nameplate on the filter.
5. Position filter so that the port locations are in the desired final positions. Follow valve installation
procedures.
6. If you have a Multiport Valve, assemble the valve to the tank, being sure the o-ring on the valve
fittings are in place and are clean. Use a lubricant, applied lightly, such as silicone grease, Dow
#33, #40 or GE 300 or 623, or similar product on o-rings and o-ring grooves prior to assembly.
7. If you have a two position slide valve, align the valve with the tank so that the handle is toward the
top of the tank, push valve into ports and turn the valve nuts snugly on the tank fittings. It is not
necessary to cinch the valve nuts to the tank fitting beyond hand tightness.
8. The shipping straps used to support the TR100C-3, TR140C and the TR140C-3 multi-diffuser
should be removed before loading sand and gravel in the filter.
9. Sand specifications – be certain the proper sand is used as described in Table 2. Before pouring
the sand into the filter, look inside and check the lower under-drain for broken or loose laterals (or
fingers), which may have been accidentally damaged by rough handling during shipment.Replace
any broken parts if necessary.
NOTE:The freeboard distanceis the most important variableand should be maintained.Sand density
will vary and therefore sand amount is given as a reference.

Failure to position theAutomatic Air Vent inside of the Closure will allow excessive trapped air to accumulate in
the filter. Trapped air and the closure not properly closed can cause the closure to seperate and could cause
severe bodily injury and/or property damage.
10. Pivot the diffuser out of the center of the tank on the TR40, 50, 60, TR60 ClearPro, 100 & 140 by
rotating the diffuser assembly counter clockwise. (NOTE: The multi-diffuser assembly should not be
moved on models TR100HD, TR100C, TR100C-3 and TR140C, TR140C-3. After installing the filter
media as described below, check to make sure the tops on the diffusers are parallel to the top of the
sandbed.) Fill the tank about half full ofwater.Pour pea gravelfirst (ifused) and then the sand into the
top of the filter at a slow rate so that the impact of the filter media does not damage the laterals.See
Table 2 for the proper amounts of sand and gravel.Fill filter to the proper level to maintain freeboard,
as shown inTable 2.Pivot the diffuser assembly back to its vertical position if it was moved.Be certain
the automatic air vent is protruding into the top of the closure as indicated below in Figure 1.Ensure
thattheautomaticairventisinthecenterofthefilterclosure.Washaway all sand around the threaded
opening at the top of the tank.
ForThreaded Closures
Use care when installing closure. The closure should turn freely in the filter, if resistance to closure
insertion is felt, then slowly remove the closure by turning counter-clockwise. The starting thread of the
tank and closure must engage properly in order to secure the closure. Do not cross-thread closure.
Failure to install the closure properly can cause the closure to seperate and could cause severe bodily
injury and/or property damage.
For Oval Closures
Use care when installing closure. The closure should be inserted into the tank by placing the small
diameter of the oval closure into the larger diameter of the tank opening. Insert the side of the closure
that does not have the pressure gauge and air bleeder first. The closure will need to be inserted at a
30° angle. Once the closure is inside the tank, it can be rotated 90° and lifted up to seal the tank. The
aluminum bridge with load spring can then be placed over the closure bolt and the hand knob tightened
to load the closure properly. The knob should be tightened by hand only. DO NOT USE A WRENCH TO
TIGHTEN THE KNOB. You could damage the tank or closure and cause a failure by using a wrench.
Failure to install the closure properly can cause the closure to seperate and could cause severe bodily
injury or property damage.
NEVER ATTEMPT TO TIGHTEN OR LOOSEN THE CLOSURE WITH THE PUMP RUNNING. Failure
to follow this instruction can result in the closure seperating and causing severe bodily injury or property
damage.
11. Assemble the pressure gauge and bleeder valve to the closure lid.Clean the lid o-ring and lubricate
with silicone grease such as Dow #33, 40 or GE 300, 623 lubricant. Place the closure lid on the filter
and tighten, making certain the air vent is up inside the dome of the closure.
12. With the plastic wrench, provided with the filter, tighten the closure as tight as possible using two
hands on the wrench handles. As a minimum, the closure
must be hand tight + 1/4 turn.
13. The oval closure that is used on the TR140C-3 and the
TR100C-3 models will need to be installed as described in
the above warning note for oval closures.
14. Assemblepipingandpipefittingstopumpandvalve.Allpiping
mustconform to local andstateplumbingand sanitary needs.
15. Use sealant compounds on all male connections of pipe
and fittings.Use only pipe compounds suited for plastic pipe.
Support pipe to prevent strains on filter, pump or valve.
16. Long piping runs and elbows restrict flow.For best efficiency,

TRITON®Fiberglass Sand Filter Installation and User’s Guide
Operating at excessive vacuum levels can cause the tank to crack and could cause property damage.
17. When installing backwash lines, it is recommended that a vacuum breaker be installed on installations where
the backwash line length exceeds 40 ft.or the backwash line discharges more than 10 ft.lower than the surface
of the pool. Alternately a vacuum break pit should be provided.
18. A check valve is recommended between the filter and heater to prevent hot water “back-up” which will damage
the filter and valve.
19. The maximum operating pressure of the unit is 50 pounds per square inch (psi) and 75 pounds per square inch
(psi) for theTriton HD model (only).Never operate this filter above these pressures or attach a pump to this filter
that has more than 50 psi shut off pressure or 75 psi shut off pressure for the Triton HD model (only).
20. Never install a chlorinator upstream of the filter. Always locate downstream and with a check valve between the
chlorinator and filter.
21. A positive shut off valve is not recommended at the outlet of the filtering system. If the system is ever run with
such a valve closed, the internal air relief system becomes inoperative and risk of tank separation could exist.
Additionally, running the system with no flow will seriously damage the equipment.
22. Never store pool chemicals within 10 ft.of your pool filter.Pool chemicals should always be stored in a cool, dry
well ventilated area.
23. The oval closure used on the TR100C-3 and TR140C-3 is designed to provide a vacuum relief mechanism that
protects the tank from vacuum conditions.The closure will allow air to enter the tank if the tank is higher that 8 ft.
above the waterlevel.Inthese cases,when thefilter restarts aftershut down,youmayobserveairbeing returned
to the pool in the return fittings.This is not unusual, it is simply the automatic air relief in the filter removing the
air in the filter.
Initial Start-up
1. On a new pool, clean the pool before filling the pool with water. Excessive dirt and large particles can cause
damage to the pump and filter.
2. Ensure the backwash line is open so that water is free to come from the pool and flow out the backwash line.
Set the valve position as follows:
a. If using a Multiport valve, set valve to backwash position.
b. If using a Two Position Slide Valve, push handle down to backwash position and engage lock by twisting
handle.
3. Check pump strainer pot to be sure it is full of water.
Air entering a filter and tank closure not installed properly can cause the closure to seperate and could cause severe
bodily injury and/or property damage.
4. Check closure on filter for tightness.
5. Open the manual air bleeder on the filter closure.Stand clear of the filter and start the pump allowing it to prime.
6. Close the air bleeder on the closure when all the air is removed from the filter and a steady stream of water
emerges.
NOTE: Pool filter sand is typically pre-washed and should not require extensive backwashing.However, the shipping
process may cause excessive abrasion which could require an extended backwash cycle at initial start-up;continue
to backwash until the backwash water is as clear as the pool water.
To prevent equipment damage and possible injury, always turn the pump off before changing the valve position.
7. Stop the pump. Set the valve position as follows:
a. If using a Multiport valve, set the valve to the filter position.
b. If using the Two Position Slide Valve, raise the handle to filter position and engage valve lock by twisting handle.
8. Ensure all suction and pool return lines are open so that water is free to come from the pool and return to the pool.
9. Open the manual air bleeder on the filter closure.Stand clear of the filter and start the pump.
10. Close the air bleeder on the filter closure when all the air is removed from the filter and a steady stream of water
emerges.
11. The filter has now started its filtering cycle.You should ensure that water is returning to the pool and take note
of the operating pressure when the filter is clean.

SECTION 3
MAINTENANCE
This section describes how to maintain yourTriton®Fiberglass Sand Filter.
Filter Care
The filter is a very important part of the pool equipment and installation.Proper care and maintenance
will add many years of service and enjoyment to the pool. Follow these suggestions for long trouble-
free operations:
1. To clean the exterior of the filter of dust and dirt, wash with a mild detergent and water then hose
off. Do not use solvents.
2. Ifinternalmaintenanceisrequired,sandmayberemovedbyremovingthesanddrainfromthebottom
of the filter and flushing with a garden hose. Pentair Sand Vacuum P/N 542090 may also be used.
3. If after a number of years, the filter tank appears foggy in color or rough in texture, the tank surface
can be painted.We recommend the use of a Quick Dry Spray Enamel.Do NOT paint the valve.
Always visually inspect filter components during normal servicing to ensure structural safety. Replace any
item which is cracked, deformed or otherwise visually defective. Defective filter components can allow
the filter top or attachments to separate and could cause severe bodily injury or property damage.
4. The filter closure on yourTriton Sand Filter was manufactured with high quality corrosion resistant
materials.Thispartshouldbecarefullyinspectedwheneverservicingyourfilter.Ifexcessiveleakage
isnotedcomingfromtheclosure/tankinterface,theclosureando-ringshouldbecarefullyinspected
and replaced if any signs of deterioration exist.
5. Your filter is a pressure vessel and should never be serviced while under pressure.Always relieve
tank pressure and open air bleeder on the filter closure before attempting to service your filter.
6. When restarting your filter, always open the manual air bleeder on the filter closure and stand clear
of the filter.
Cleaning Frequency
1. The filter on a new pool should be backwashed, and cleaned after approximately 48 hours of
operation to clean out plaster dust and/or construction debris.
2. There are three different ways to identify when the filter needs backwashing.
a. The most accurate indicator on pool systems with a flow meter is to backwash when the
flow decreases 30% from the original (clean filter) flow.For example, if the original flow was
60 GPM, the filter should be backwashed when the flow is reduced by about 20 GPM (or
30%) to 40 GPM.
b. A more subjective and less accurate indicator is to observe the amount of water flowing
from the flow directionals located in the wall of the pool.The filter should be backwashed
once it is detected that the flow has been reduced by about 30%.
c. The most commonly used but less accurate indicator is to backwash when the filter gauge
reading increases 10 PSI over the initial (clean filter) reading.
3. It is important not to backwash the filter solely on a timed basis such as every three days. It is
also important to note that backwashing too frequently actually causes poor filtration.Factors like
weather conditions, heavy rains, dust or pollen, and water temperature all affect the frequency of
backwash.As you use your pool, you will become aware of these influences.
4. If at any time the starting pressure after backwashing the filter indicates 4 to 6 PSI higher than
normal starting pressure, it is time to perform a chemical cleaning procedure.

TRITON®Fiberglass Sand Filter Installation and User’s Guide
Filter Backwash Procedure
To prevent equipment damage and possible injury, always turn off pump before changing valve positions.
1. Stop the pump.
2. Ensure that the suction and backwash lines are open so that water is free to come from the pool
and flow out the backwash line.Set control valve position as follows:
a. If using a Multiport Valve, set valve to backwash position.
b. If using a Two Position Slide Valve, push handle down to backwash position and engage lock
by twisting handle.
3. Stand clear of the filter and start pump.
4. Backwash filter for approximately 3 to 5 minutes or until backwash water is clean.
5. Stop the pump.
a. If using a Multiport Valve, set valve to rinse position and continue with remaining steps.
b. If using a Two Position Slide Valve, skip to step 8.
6. Stand clear of the filter and start pump.
7. Rinse filter for approximately 30 seconds.
8. Stop the pump and set valve as follows:
a. If using a Multiport Valve, set valve to filter position.
b. If using a Two Position Slide Valve, raise handle to filter position and engage valve lock by
twisting handle.
9. Ensure that pool return line is open so that water may freely flow from the pool back to the pool.
10. Open manual air bleeder on Triton closure. Stand clear of filter and start pump.
11. Close manual air bleeder of the closure when all the air is removed and a steady stream of water
emerges from the bleeder.
12. The filter has now started its filtering cycle.You should ensure that water is returning to the pool
and take note of the filter pressure.
13. The filter pressure, in the above Step 12, should not exceed the pressure originally observed on
the filter when it was initially started. If after backwashing, the pressure is 4 to 6 PSI above the
start condition, it will be necessary to chemically clean the sand bed.

TRITON®Fiberglass Sand Filter Installation and User’s Guide

ENGLISH
Chemical Cleaning Procedure
1. It is recommended that an approved cleaner be used. Please contact your local pool chemical
supplier or retail store for the proper cleaner.
These cleaners will remove oils, scale and rust from the sand bed in one cleaning operation.
2. Mix a solution following the manufacturers instructions on the label.
3. Backwash the filter as outlined on page 8.
4. If the filter is below pool level, shut off the pump and close appropriate valving to prevent draining
the pool.
5. Shut off pump, open filter drain and let filter drain. Place valve in backwash position.
6. After filter has drained, close filter drain and remove the pump strainer pot lid.
7. Ensure that the backwash lines are open.
8. Turn the pump on and slowly pour the cleaning solution into the pump strainer with the pump
running.
9. Continue adding solution until the sand bed is saturated with cleaning solution. Replace lid on
pump.
10. Shut off the pump and leave filter in backwash position. Allow filter to stand overnight (12 hours).
11. Replace the pump lid and follow backwash procedures on page 8.
12. Do not allow the cleaning solution to get into the pool.
Winterizing your Filter
1. In areas that have freezing winter temperatures, protect the pool equipment by backwashing the
filter.
2. After backwashing, shut the pump off, open the manual air bleeder on the closure and adjust the
valve as follow:
a. On the Multiport Valves, move the handle of the valve to the Winterize Position (*).
b. On the Two Position Slide Valve, if possible, remove the valve piston assembly; clean,
lubricate and store in a dry location for the winter.
*NOTE: The Multiport valve should be left in the winterize position during shutdown season so the
valve diverter has no pressure on the rubber seal.
3. On the TR40, 50, 60, and TR60 ClearPro, remove the wing-type plug on the bottom of the filter.
On the TR100, TR100HD, TR100C, TR100C-3, and TR140, TR140C, TR140C-3, remove the 1½”
drain plug cap.The filter will drain very slowly, and therefore, it is recommended that the drain plug
be left out.
4. Drain all appropriate system piping.
5. We recommend covering the equipment with a tarpaulin or plastic sheet to inhibit deterioration
from weather. Do NOT wrap pump motor with plastic.

TROUBLESHOOTING
Use the following troubleshooting information to resolve possible problems with your Triton®Filter.
THIS FILTER OPERATES UNDER HIGH PRESSURE
When any part of the circulating system, (e.g., closure, pump, filter, valve(s), etc.), is serviced, air can enter
the system and become pressurized. Pressurized air can cause the top closure to separate which can
result in severe injury, death, or property damage. To avoid this potential hazard, follow these instructions:
1. If you are not familiar with your pool filtering system and/or heater:
a. DoNOT attempt toadjust or servicewithoutconsulting your dealer,or a qualifiedpool
technician.
b. Read the entire Installation & User’s Guide before attempting to use, service or adjust
the pool filtering system or heater.
2. Before repositioning valve(s) and before beginning the assembly, disassembly, 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
bleeder valve; (C) wait until all pressure is relieved.
3. Whenever installing the filter closure FOLLOW THE FILTER CLOSURE WARNINGS EXACTLY.
4. Once service on the circulating system is complete FOLLOW INITIAL START-UP INSTRUCTIONS
EXACTLY.
5. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., closure,
pressure gauge, valve(s), o-rings, etc).
6. Be sure that the filter is properly mounted and positioned according to instructions provided.
NOTE: Turn off power to unit prior to attempting service or repair.
Problems and Corrective Actions
PROBLEM CAUSE REMEDY
Pool water not sufficiently clean 1. Pool chemistry not adequate to inhibit Maintain pool chemistry or consult pool service
algae growth. technician.
2. Too frequent a backwash cycle. Allow pressure to build to 10 psi above clean
