3. START-UP
1. Take the cover(s) off the housing in order to begin the start-up. Unscrew the 6 screws that join the cover
to the hinge, before lifting it off.
2. Open the filter and fill with water half way up. Protect the diffuser inside the filter so that no sand can get
into it.
3. Fill the filter with silex sand of a 0.4–0.8 grain size with the amount shown on the label or 2/3 of the way
up the total filter height.
4. Assemble the pressure gage, the seal and the air bleed cap. It is not necessary to use Teflon seal tape, as
the seal makes this joint watertight. Do not use any tools to tighten the pressure gage's T-piece. Tightening
it by hand will suffice.

5. Clean any remaining sand off the opening and the cover, as well as off the seal housing and close the filter.
For further information, see the filter's manual.
6. If the housing were above the pool's water level, the pump must be primed by opening the prefilter and filing
it with water.
7. If the housing were below the pool's water level, just open the pressure and check valves, and open the air
bleed valve until the filter and pump are full of water.
8. Place the valves in the following positions.
- SKIMMER: OPEN
- MAIN DRAIN: OPEN
- POOL CLEANER: OPEN
- CHECK VALVE: OPEN
- SELECTOR VALVE: BACKWASH
9. Turn the filter on and backwash it. Backwash until crystal clear water can be seen through the selector valve's
sight glass.
10. Turn the pump off. Put the selector valve in the rinse position and turn on the pump for 15 seconds. Turn the
pump off again and put the selector valve in the filtration position.
