You have just become the owner of a sand filter, his base and his valve (see figure 1).
Your filtration system uses a 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.
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 (16), and the drain plug (14) 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 manufacturer's instructions.
3. Filling the filter
The sand is put in through the opening in the top of the filter.
a. Remove diffuser (7) and pull aside air relief tube (12). Cover the opening in the top of the elbow (8) with the cap provided
for this purpose, to prevent any sand getting in it during filling. Make sure that the drain plug (14) is in place. All laterals
(10) 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).
The surface of the sand should be levelled and reach the middle of the filter.
c. Remove the cap .
d. Replace diffuser (7) on top elbow.
e. Replace air relief tube (12). Place O-Ring (4) on dome (3), install manual air relief cap (1) with his O-Ring (2) and place
dome, once complete, on top of the filter.
f. Fix dome (3) on valve with the clamp (5). There should be around 5 mm of space left between the two parts of the clamp.
4. Assembling the valve
a. Make sure that the «PUMP» outlet of the valve its towards the pump. Align the two valve pipe connections, with O-Rings
in place, with the two openings in the side of the filter tank and press in firmly. Secure the assembly to the tank connec-
tions with the two bulkhead locknuts (17).
b. Remove the black plastic screw on the side of the valve and replace it with the pressure gauge (18). Screw in by hand
without forcing.
c. Connect the «PUMP» outlet (P) of the valve to the top outlet of the pump as indicated 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
prefilter side, the discharge pipes to the valve port marked «RETURN» (R), and the drain connection to the valve port
marked «WASTE» (W).
6. Make the electrical connections of the pump as indicated by the manufacturer's instructions.
7. To avoid leaks, make sure that the drain plug (14) in place and that all connections are tight.
Note 1: Do not force when screwing the connection end fittings into the valve unions.
Note 2: Coat the male threads with Teflon.
IMPORTANT: ALWAYS STOP THE PUMP BEFORE OPERATING THE MULTI-WAY VALVE.
1. Check that all connections are tight and that the filter contains just the right amount of sand.
2. Set the valve to «BACKWASH». Always lower the handle before turning.
3. Start the pump as indicated by the manufacturer's instructions. Check that water flows normally in the circuit.
WARNING: All suction and discharge valves must be open when the pump is started. Otherwise, there is a risk
of property damage, grave injury, or death.
Once the water flows smoothly, let the pump run for at least another 2 minutes. This backwash is recommended to elimi-
