Kenmore REVERSE OSMOSIS 625.38556 - Manual (Page 17)

Step 7 - Sanitize, Test and Purge System
PRESSURE TEST THE SYSTEM
NOTE: Complete the sanitizing procedures on the preced­
ing page before pressure testing.
To pressure test the system, complete the following steps.
1. Open the water supply valve to the Reverse Osmosis
System. See Figure 23.
2. Open the main water supply valve and several house
faucets. This will purge air from the house plumbing
and system. Close faucets when water runs smooth. See
Figure 23.
3. Pressure will start to build in the RO system in about 2
hours Carefully check all fittings and connections as the
system builds pressure. Check for water leaks. Fix leaks
if any are found. If problems exist, refer to the trou­
bleshooting chart or call the toll free number.
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:
You will not have filtered water immediately. It may
take 1-3 hours to completely fill the storage tank and
create maximum flow from the Reverse Osmosis faucet.
Water Pressure from the Reverse Osmosis faucet will be
less than your standard 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 for a cou­
ple of hours. Water going to the drain will automati­
cally shut off when the storage tank is full.

NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber and do not permit the
use of saddle valves.
If you live in the state of Massachusetts, review plumb­
ing code 248-CMR of the Commonwealth of
Massachusetts before proceeding with the installation.
PURGING THE SYSTEM
To purge the system, complete the following steps.
1. Open the Reverse Osmosis Faucet and let water
through the system for a 24 hour period.
NOTE: Water flow will be a slow trickle at this time.
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.
