You have just become the owner of a sand filter, his base and his valve (see figure 1).
OPERATION
Your filtration system uses special sand designed to trap impurities in the pool water.
The sand is poured into the tank and acts as a permanent filtration system. The
pump draws in the unfiltered pool water, which contains impurities in suspension
and feeds it to the multi-way control valve. When the water flows through the sand,
the impurities are trapped there and the water that returns to your pool is filtered.
INSTALLATION
1. Locating the filter
Find a clean, level spot. The top of the filter must be at least 1.5 m distant from
the water level. Place the filter so that the piping, the valve (1), and the drain
plug (10) are easy to reach. This will make servicing and winterizing easier.
2. Assembling the pump
Assemble the pump and its mount with the filter as indicated by the manufac-
turer's instructions.
3. Filling the filter
The sand is put in through the opening in the top of the filter.
a. Place the centre tube (6) on the bottom of the tank and cover the opening in
the top of the tube with funnel (5) provided for the purpose, to prevent any sand
getting in it during filling. Make sure that the drain plug (10) is in place. All lat-
erals (8) must be in the down position.
b. Half-fill the filter with water, then pour in the required quantity of sand (Cf. table
on label).
Check that the centre tube (6) remains straight.
The surface of the sand should be leveled and reach the middle of the filter.
c. Remove the funnel (5).
4. Assembling the valve
Place the valve (1), with its gasket (3), on the top of the filter.
a. Make sure that the "PUMP" outlet of the valve its towards the pump. Then
attach with the clamp (4).
b. Remove the black plastic screw on the side of the valve and replace it with the
pressure gauge (2). Screw in by hand without forcing.
c. Connect the "PUMP" outlet (P) of the valve to the top outlet of the pump as indi-
cated by the manufacturer's instructions
5. Connecting the valve
Then simply connect the pipes from the pool (cf. fig. 2) and from the skimmers
(S) to the bottom port of the pump, on the strainer side, the discharge pipes to
the valve port marked "RETURN" (R), and the drain connection to the valve port
marked "WASTE" (W)
