TO FLUSH THE PURE WATER UNIT
Step 1:
For Units with Manual Freshwater Flush Valve Assembly:
Turn
ON
your water pressure and watermaker breakers on main electrical panel. Turn the High
Pressure Bypass Valve to
CLEANING
(ensuring zero pressure in system). Verify the gray Cleaning
Valve is positioned to
NORMAL/REVERSE OSMOSIS
position. Turn the Flush valve to freshwater
position to start flow through the unit.
For Units with Automatic Freshwater Flush Valve Assembly:
Verify the gray Cleaning Valve is positioned to
NORMAL/REVERSE OSMOSIS
position. Verify the
isolation valve before the carbon filter is open.
Step 2:
Verify the freshwater supply pressure on the Vacuum/Pressure Gauge of micron filter assembly (Refer
to Figures 4.1, 4.3, 4.4) does not exceed 35 psi. If it does, install a regulator in the fresh water supply
branch.
Step 3:
Press the
FLUSH
pushbutton located on the Master Control Center on the electronic instrument panel
(or the Remote Control Center, if equipped). This will automatically begin the freshwater flush cycle
within the RO system. The electronic flush will automatically start the Low Pressure Boost Pump, then
the High Pressure Pump, and begin the flushing process for a period of two minutes. Discharge
overboard should be visible during flush.
After flushing the unit for two minutes, the High Pressure Pump and Low Pressure Pump will shutdown
respectively. A confirmation of completion of the Freshwater Flush is displayed on the Master Control
Center, reading STANDBY.
Step 4:
For Units with Manual Freshwater Flush Valve Assembly:
Turn the Freshwater Flush Valve to
SEAWATER
position. Leave RO unit in standing condition, for up to
three weeks. Then reflush or preserve.
For Units with Automatic Freshwater Flush Valve Assembly:
Leave RO unit in standing condition, for up to three weeks. Then reflush or preserve.
