System Activation and Flushing
System Activation
1. Check all tubing connections to ensure they are firmly seated. CHECK TO SEE THAT THE CARTRIDGE
RETAINER CLIPS AND LOCKS ARE PROPERLY ENGAGED. Failure to keep the retaining clips in place could
result in accidental leaks and flooding.
2. Open the dispensing faucet at the sink. Close the tank shut-off valve.
3. Open the feed water valve to the system. Observe all tubing and connections for several minutes to detect
any leaks. In approximately 5 minutes, (assuming normal feed water pressure) the dispensing faucet should
begin dripping.
4. Place a pan or other tempo rary water basin near the drain 'P' trap. Loosen the connector nut holding the 3/8"
tube in the drain saddle connec tor. Pull the tube out of the connector and use the pan to catch any water that
may spill. Brine water should be flowing from the tube. Reconnect the tube to the drain saddle and hand-tight en
the connector nut.
5. Allow the faucet to run for up to 15 minutes, then close the faucet.
6. Check connections for leaks.
7. Open the tank shut-off valve.
Initial Flushing Procedure
1. Before the system can be used for drinking water production it must be adequately flushed. Each reservoir
tank is dosed with a small amount of powdered chlorinated sanitizer before shipment in order to ensure tank inter-
nal cleanliness. Also, the carbon filter cartridges will release a small amount of carbon fines during the first tankful
of flow. This flushing procedure will allow any sanitizer or carbon fines to pass from the system.
2. Initial tank filling will take approximately two and one half hours (based on average feed pressure). When the
tank is full, the water pressure will have risen to the point where the automatic shut-off valve inside the unit will
stop the feed flow through the system. Actuation of the automatic shut-off valve can be determined by checking
for a lack of brine flow to the drain saddle. When the tank has filled for the first time, it should be left undisturbed
for at least 8 hours to ensure proper sanitization.
3. After 8 hours have elapsed, open the dispensing faucet fully and allow the product water to run out to drain
at maximum flow. The initial discharge will be dark with the bulk of the carbon particle wash out. There may also
be the scent of chlorinated water from the sanitizing agent. When the flow has diminished to a fast drip or small
stream, close the dispensing faucet.
4. Fill and flush the tank at least three times prior to use. If necessary, repeat until the chlorination scent has
disappeared. It is important that the flush be done at maximum flow (e.g. the tank must be full) to assist in rapid
wash out. After this flushing procedure the system is ready for normal use.
