6. Make the electrical connections of the pump as indicated by the manufactur-
er’s instructions.
7. To avoid leaks, make sure that the drain plug (10) 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 filtering sand.
4. On four-way valves, wait 1 minute.
On six-way valves, 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/cm²),
the 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 trou-
ble-free operation of your filtration system.
