With the raw water pump primed, the discharge hose will quickly fill and harden with pressure. Check the hose and
the media inlet/outlet pressure gage (1) to assure pressure has been established.
If pressure is not observed check the raw water hose for kinks, sharp bends, or leaks.
Check that control panel and valves are set up properly.
Push CHEMICAL PUMP START (6).
When media inlet/outlet pressure gage (1) reading steadies, push BOOSTER PUMP START (3), and slowly close
feed valve (4) until feed flowmeter (5) reads 100 gpm.
If 100 gpm cannot be obtained check as follows:
· Check discharge hose for kinks restricting the water flow.
· Check valves for proper position.
· Check suction hose connections to assure tightness.
· Refer to Troubleshooting.
Open media filter vent valve (2), close, when a steady stream of water is seen.
Hold steady condition (no control operations) for 10 minutes.
Fully open cartridge filter block valve (7) and feed valve (4).
Fully open system pressure control valve (12) by turning handle counterclockwise until it stops turning.
Push MEDIA FILTER FORWARD FLUSH (8) to close this valve. The FEED PRESSURE low light (9) should come
on and the booster pump will shut off.
Open cartridge filter vent valve (10); close when water is seen.
Product shut-off valve should be in the open position.
Check product shut-off valve (11). It must be open.
If the RO vessels am empty or there is not enough pressure in the vessels, the FEED
PRESSURE low light will come on, and the booster pump will shut off.
When the media inlet/outlet pressure gage (1) reads between 35 and 40 psig (241 and 276 kPa), the FEED
PRESSURE low light (9) will go off. When the light goes off, push BOOSTER PUMP START (3).
