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.
WARNING —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.
WARNING —To reduce the risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
WARNING — 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 blow off and could cause severe personal
injury or death if they were to strike a person.
WARNING — Never exceed the maximum operating pressure of the system components. Exceeding these

Installation
Note: Before installing this product, read and follow all warning notices and instructions starting
on page ii.
Installing the Triton® 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.
Triton® 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 your Triton® Filter works
Your high rate sand filter 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 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.
The pressure will rise and the flow to the pool will be lowered as the dirt is collected in the filter. Eventually, the filter
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 filter. Backwashing is discussed further under 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
WARNING — 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 specialized
area and you should consult your local pool service specialist for specific 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.
WARNING — 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. Mount the filter 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 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 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.

Triton®Fiberglass Sand Filter Installation and User’s Guide
WARNING — 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
blow off 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
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 sand bed.) Fill the tank about half full of water. Pour
pea gravel first (if used) 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 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 filter closure. Wash away all sand around the threaded
opening at the top of the tank.
WARNING —For Threaded 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 blow off and could cause severe
bodily injury and/or property damage.
WARNING —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 blow off 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 blowing off 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. Assemble piping and pipe fittings 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 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, use the fewest possible number of fittings, 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
CAUTION —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 the Triton 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 an explosive situation 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 water level. In these cases, when the filter restarts after shut down, you may observe air being 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.
WARNING — Air entering the filter and the tank closure not installed properly can cause the closure to blow off 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.
CAUTION — 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. Closetheairbleederonthefilterclosurewhenallthe air is removedfromthe filter anda steady streamof 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 your Triton®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. If internal maintenance is required, sand may be removed by removing the sand drain from the bottom of the filter
and flushing with a garden hose. Pentair Water Pool and Spa®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.
WARNING — 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 blow off and could cause severe bodily injury or property
damage.
4. The filter closure on your Triton Sand Filter was manufactured with high quality corrosion resistant materials.
This part should be carefully inspected whenever servicing your filter. 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 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
WARNING —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
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,
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.
WARNING — 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.
Note: Turn off power to unit prior to attempting service or repair.
