Initial Startup Of Filter; Backwashing - Waterco Aquaswim Montage- Und Betriebsanleitung

INITIAL STARTUP OF FILTER

Be sure correct amount of filter media is in the filter vessel and that all connections are hand tightened.
1. Depress Multiport Valve handle and rotate to the BACKWASH position and open the air release valve
on the filter or Multiport Valve.
NOTE: To prevent damage to control valve seal, always depress handle before turning.
2. Switch on the Pump / Open the Inlet Valve allowing the filter vessel to fill with water.
NOTE: If a pump is installed, switch the pump on and off, instead of closing and
opening the Inlet Valve.
3. One a steady flow of water is running through the waste line, close the air release valve and let the
pump run until the waste water is clear. The initial backwashing of the filter is recommended to
remove any impurities or fine particles from the filter media until the sight glass is clear. This process
may take up to 3 minutes.
4. Turn the pump off, Multiport Valve to the RINSE position. Switch on the Pump / Open the Inlet Valve
until water in sight glass is clear — approximately 10 to 15 seconds .
5. Switch off the Pump / Close the Inlet Valve, set the Multiport Valve to the FILTER position and Switch
on the Pump / Open the Inlet. The filter is now operating in its normal filter mode.
6. Adjust pool suction and return valves to achieve desired flow. Check the plumbing and filter for water
leaks and tighten connections, bolts, and nuts, as required.
7. Record the pressure gauge reading (start up pressure) during initial operation. After a period of time,
the accumulated dirt and debris in the filter causes a resistance to flow, and the flow diminishes.
The pressure will start to rise and the flow of water will start diminishing. When the pressure gauge
reading is 50 kPa (7.2 psi) higher than the initial "Start up" pressure, it is time to backwash (clean) the
filter (see Backwashing).
NOTE: If the filter is connected to mains water, it is not necessary to record the "Start up" pressure,
as mains pressure tends to fluctuate.

BACKWASHING

The function of backwashing is to separate the deposited particles from the filter media grains and flush
them from the filter bed. Backwashing is achieved by reversing the flow of water through the filter bed
at a fairly high flow rate. This high flow rate expands the filter bed and the water flow carries the debris
out to waste.
