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.
