PURGINGTHESYSTEM
To purge the system, complete the following steps.
1. Open the Reverse Osmosis Faucet and let water
flow through the system for a 24 hour period. Water
flow will be a slow trickle at this time.
NOTE:DonotconsumewaterfromtheROsys-
temuntilpurgingiscomplete.
2. Close the Reverse Osmosis faucet after the 24 hour
purging period is complete.
3. When the purging is finished, your Reverse
Osmosis system is ready for use.
You will not have filtered water immediately. It may
take several hours to fill the storage tank and create
maximum flow from the Reverse Osmosis faucet.
Water will run to the drain while the Reverse
Osmosis system is producing water, even if you are
not drawing water from the Reverse Osmosis faucet.
You may hear a small quantity of water going to the
drain at times when water is not being used. This is
normal. Water going to the drain will automatically
shut off when the storage tank is full.
Water Pressure from the Reverse Osmosis faucet will
be less than your standard faucet.
