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.
