Initial Start-Up - Pentair Triton TR 100HD Installation & User Manual

6
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. 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.
