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

Installing theTriton®Fiberglass Sand Filter
Only a qualified service person should install the Triton Fiberglass Sand 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 lter 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 afxed to the top of the lter and should not be removed. Keep safety labels in good condition and replace
if missing or illegible.
How the Filter works
The high rate sand lter is designed to operate for years with a minimum of maintenance and when installed,
operated and maintained in accordance with these instructions, it will provide years of trouble free operation.
Dirt is collected in the lter as the water ows through the control valve at the side of the lter and is directed
into the top bulkhead. Dirty water ows into the diffuser at the top of the tank and is directed downward into
the top surface of the lter sand bed. The dirt is collected in the sand bed and the clean water ows through the
laterals and lower piping at the bottom of the lter up into the lower bulkhead. The ow then goes into the control
valve at the side of the lter. Clean water is returned through the piping system into the pool.
The pressure will rise and the ow to the pool will be lowered as the dirt is collected in the lter. Eventually, the
lter will become so plugged with dirt that it will be necessary to perform the backwash procedure. It is important
to know when to backwash the lter. Backwashing is discussed further under the subsequent sections of this guide.
Please note that a lter 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 ltration 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 ltration as well as proper water chemistry. Pool chemistry is a specialized area
and you should consult your local pool service specialist for specic details. In general, 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 lter components
are damaged, notify the freight carrier immediately.
2. Carefully remove the accessory package and the lter tank from the carton.
3. Mount the lter on a permanent slab, preferably concrete poured in a form or on a platform constructed of
concrete block or brick. DO NOT use sand to level the lter 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 lter.
One needs to be able to stand clear of the lter when starting the pump. Minimum space requirements may
be found on the large nameplate on the lter.
5. Position lter so that the port locations are in the desired nal 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 ttings 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 ttings. It is not necessary to cinch
the valve nuts to the tank tting 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 lter.
9. Sand specications – be certain the proper sand is used as described in Table 2. Before pouring the sand into
the lter, look inside and check the lower under-drain for broken or loose laterals (or ngers), which may
have been accidentally damaged by rough handling during shipment. Replace any broken parts if necessary.
NOTE:The free board distance is the most important variable and should be maintained. Sand density will vary
and therefore sand amount is given as a reference.
† Media required to meet NSF requirements.
‡ Pea Gravel to be 1/4” to 1/8” diameter.
* Sand to be No. 20 standard silica (uniformity coefficient not greater than 1.75) .018-.020 in diameter particle size.

Failure to position the Automatic 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 lter media as described below,
check to make sure the tops on the diffusers are parallel to the top of the sand bed.) Fill the tank about half
full of water. Pour pea gravel rst (if used) and then the sand into the top of the lter at a slow rate so that the
impact of the lter media does not damage the laterals. See Table 2 for the proper amounts of sand and gravel.
Fill lter to the proper level to maintain freeboard, as shown in Table 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 that the automatic air vent is in the center of the lter closure. Wash away
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 lter and tighten, making
certain the air vent is up inside the dome of the closure.
12. With the plastic wrench, provided with the lter, 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. Assemble piping and pipe ttings to pump and valve. All piping must
conform to local and state plumbing and sanitary needs.
15. Use sealant compounds on all male connections of pipe and ttings. Use
only pipe compounds suited for plastic pipe. Support pipe to prevent
strains on lter, pump or valve.
16. Long piping runs and elbows restrict ow. For best efciency, use the
fewest possible number of ttings, and large diameter pipe (at least 2”
for TR100 and TR140, at least 3” for TR100C-3 and TR140C-3).

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 lter and heater to prevent hot water “back-up” which will damage
the lter 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 the Triton HD model (only). Never operate this lter above these pressures or attach a pump to this lter
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 lter. Always locate downstream and with a check valve between the
chlorinator and lter.
21. A positive shut off valve is not recommended at the outlet of the ltering 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 ow will seriously damage the equipment.
22. Never store pool chemicals within 10 ft. of your pool lter. 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 water level. In these cases, when the lter restarts after shut down, you may observe air being returned
to the pool in the return ttings. This is not unusual, it is simply the automatic air relief in the lter removing the
air in the lter.
Initial Start-up
1. On a new pool, clean the pool before lling the pool with water. Excessive dirt and large particles can cause
damage to the pump and lter.
2. Ensure the backwash line is open so that water is free to come from the pool and ow 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 lter for tightness.
5. Open the manual air bleeder on the lter closure. Stand clear of the lter and start the pump allowing it to prime.
6. Close the air bleeder on the closure when all the air is removed from the lter and a steady stream of water emerges.
NOTE:Pool lter 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 lter position.
b. If using the Two Position Slide Valve, raise the handle to lter 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 lter closure. Stand clear of the lter and start the pump.
10. Close the air bleeder on the lter closure when all the air is removed from the lter and a steady stream of water
emerges.
11. The lter has now started its ltering cycle. You should ensure that water is returning to the pool and take note
of the operating pressure when the lter is clean.

Section 3
Maintenance
This section describes how to maintain your Triton® Fiberglass Sand Filter.
Filter Care
The lter 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 lter of dust and dirt, wash with a mild detergent and water then hose off. Do
not use solvents.
2. If internal maintenance is required, sand may be removed by removing the sand drain from the bottom of the
lter and ushing with a garden hose. Pentair Water Pool and Spa, Inc. Sand Vacuum P/N 542090 may also
be used.
3. If after a number of years, the lter 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 seperate and could cause severe bodily injury or property damage.
4. The lter closure on your Triton Sand Filter was manufactured with high quality corrosion resistant materials.
This part should be carefully inspected whenever servicing your lter. If excessive leakage is noted coming
from the closure/tank interface, the closure and o-ring should be carefully inspected and replaced if any
signs of deterioration exist.
5. Your lter is a pressure vessel and should never be serviced while under pressure. Always relieve tank
pressure and open air bleeder on the lter closure before attempting to service your lter.
6. When restarting your lter, always open the manual air bleeder on the lter closure and stand clear of the
lter.
Cleaning Frequency
1. The lter 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 lter needs backwashing.
a. The most accurate indicator on pool systems with a ow meter is to backwash when the ow decreases
30% from the original (clean lter) ow. For example, if the original ow was 60 GPM, the lter should
be backwashed when the ow 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 owing from the ow
directionals located in the wall of the pool. The lter should be backwashed once it is detected that the
ow has been reduced by about 30%.
c. The most commonly used but less accurate indicator is to backwash when the lter gauge reading
increases 10 PSI over the initial (clean lter) reading.
3. It is important not to backwash the lter solely on a timed basis such as every three days. It is also important
to note that backwashing too frequently actually causes poor ltration. 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 inuences.
4. If at any time the starting pressure after backwashing the lter indicates 4 to 6 PSI higher than normal starting
pressure, it is time to perform a chemical cleaning procedure.

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 ow 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 lter and start pump.
4. Backwash lter 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 lter and start pump.
7. Rinse lter for approximately 30 seconds.
8. Stop the pump and set valve as follows:
a. If using a Multiport Valve, set valve to lter position.
b. If using a Two Position Slide Valve, raise handle to lter position and engage valve lock by twisting
handle.
9. Ensure that pool return line is open so that water may freely ow from the pool back to the pool.
10. Open manual air bleeder on Triton closure. Stand clear of lter 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 lter has now started its ltering cycle. You should ensure that water is returning to the pool and take
note of the lter pressure.
13. The lter pressure, in the above Step 12, should not exceed the pressure originally observed on the lter
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.

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 lter as outlined on page 8.
4. If the lter is below pool level, shut off the pump and close appropriate valving to prevent draining the pool.
5. Shut off pump, open lter drain and let lter drain. Place valve in backwash position.
6. After lter has drained, close lter 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 lter in backwash position. Allow lter 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 lter.
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 lter. On the
TR100, TR100HD, TR100C, TR100C-3, and TR140, TR140C, TR140C-3, remove the 1½” drain plug cap.
The lter 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 attemptto adjust orservice withoutconsulting your dealer, or aqualified 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-UPINSTRUCTIONS
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.
