Follow the instructions in the programming section of this service manual to setup the timer.
Check the FreshPoint™ For Leaks
Ensure that all new plumbing connections, the three ports from the housing, and the two end cap perimeters
have no leaks. Correct if needed.
Manually initiate a flush cycle by pressing the Extra Cycle button. Ensure the drain solenoid valve opens and
that a robust flow goes to the drain, and that the drain can handle the flow.
Flushing
Flush the membranes prior to placing the system in service to remove the membrane storage solution.
NOTE: If installed, the backflush tank isolation valve should be closed. If there is a tank and no isolation
valve, ensure that each flush cycle fills and empties the backflush tank.
NOTE: If installed with the backflush kit, the inlet solenoid valve should not be connected to the wiring
harness for flushing, as it will not permit easy removal of air from the system if operating.
Rinse the preservative solution from the membrane as follows:
Close the bypass valve of the bypass plumbing arrangement.
Open the outlet valve of the bypass plumbing arrangement.
Slowly open the inlet valve of the bypass plumbing arrangement. This will fill the module with water without
creating a water hammer effect.
To expel air from the feed side of the membrane initiate at least two successive flush cycles by pressing the
Extra Cycle button on the timer.
Rinse Cycle 1:
Open the service water faucet closest to the FreshPoint™ installation to permit a flow of five gallons per
minute. Allow the system to flush for twenty minutes.
Initiate two successive flushes to drain by pressing the Extra Cycle button on the timer.
If a backflush tank is installed and not isolated, ensure that it is emptied by initiating successive flushes by
pressing the Extra Cycle button on the timer.
Rinse Cycle 2:
Allow the service water to continue to flow at five gallons per minute. Permit the system to flush for an
additional twenty minutes.
Initiate two successive flushes to drain by pressing the Extra Cycle button on the timer.
If a backflush tank is installed and not isolated, ensure that it is emptied by initiating successive flushes by
pressing the Extra Cycle button on the timer.
Rinse Cycle 3:
Allow the service water to continue to flow at five gallons per minute. Permit the system to flush for an
additional twenty minutes.
Initiate two successive flushes to the drain by pressing the Extra Cycle button on the timer.
If a flush tank is installed, ensure that it is emptied by initiating successive flushes by pressing the Extra Cycle
button on the timer.
While the system is flushing check all plumbing connections for any possible leaks.
