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 (15) in in place and that all connec-
tions 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.
STARTING UP
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 eliminate any impurities or fine particles from the fil-
tering sand.
4. Stop the pump and set the valve to «RINSE». Restart the pump and let run until the
water becomes clear in the valve circulation telltale (about a minute).
5. Stop the pump and set the valve to «FILTER». Restart the pump and filtering starts.
Adjust the inlet and outlet valves for the desired water flow.
6. Carefully note the pressure reading at that time and the position of the needle on
the pressure gauge. As the filter operates, impurities are retained and the pressure
increases in the tank.
When it exceeds the initial pressure (clean filter) by 10 PSI (0.7 bars or kg/cm
filter must be backwashed.
Note 1. When your pool's water is cleaned for the first time, it may be necessary to
backwash the filter frequently: the quantity of impurities is likely to be large.
Note 2. Clean the pre-filters of the pump and skimmers regularly to ensure trouble-free
operation of your filtration system.
Note 3. Installations including heaters or cleaning systems with nozzles or tentacles
protruding from the walls are highly sensitive to hydraulic rams because they operate
at high pressure. The installer must do everything necessary to prevent hydraulic rams
in the installation.
