PRESSURE TEST THE SYSTEM
NOTE: Complete the sanitizing procedures on the
preceding page before pressure testing.
To pressure test the system, complete the following
steps.
1
. Open the water supply valve to the Reverse
Osmosis system.
2
. Purge air from the house plumbing by opening sev-
eral house faucets. Close faucets when water runs
smooth, with no spurting.
3
. Pressure will start to build in the RO system. In
about 2 hours check all fittings and connections.
Check for water leaks. Fix leaks if any are found. If
problems exist, refer to the troubleshooting chart or
call the toll free number below).
NOTE: When the system is first pressurized, water
may ''spurt'' from the faucet air gap hole until air is
expelled from the RO system.
Please review the following operating features
before using your Reverse Osmosis system:
4
. When the storage tank is empty (the water flow from
the RO faucet will slow to a trickle), close the RO
faucet and allow the storage tank to fill again.
5
. Purging is complete, and your Reverse Osmosis
system is ready for use.
NOTE: As with all other water system applications,
leaks may occur. Because the system pressure
builds slowly, leaks may not be immediately appar-
ent. Recheck for leaks 24 hours after purging the
system is complete.
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 24 hours. Water flow
from the faucet 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 RO faucet after the 24 hour period is
complete, and allow the storage tank to fill. This
may take several hours.
3
. When the storage tank is full (you will no longer
hear water trickling into the drain), open the RO
faucet and allow the storage tank to empty.
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.
