Step 8: Sanitize, Test and Purge
SANITIZE
(
Note: Sanitization is recommended immediately after RO Filter System installation and any
inner-part servicing. The person sanitizing should have clean hands during this process.)
1. Shut off water supply to RO system.
2. Open faucet. If tank is not empty, allow
to drain until empty.
3. With included eyedropper and house-
hold bleach (5.25%), disconnect white
tubing from the manifold outlet labeled
“TANK”. Note: Bleach needs to be
handled according to manufacturer’s
instructions.
4. Add 3ml bleach into open end of tank
white tubing.
5. Reconnect the tank from the tube into
the manifold outlet labeled “TANK”.
Be sure to push tubing in all the way.
6. Sanitation will be completed during the following pressure test and purge. Important:
Bleach must be completely removed from system before drinking water. See Purge
instructions below.
PRESSURE TEST
(
Important: Complete sanitization prior to pressure test.)
1. Open cold water supply valve to RO Filter System.
2. To purge air from the plumbing system, open kitchen faucet. Close faucet when water
runs smooth.
3. Confirm RO faucet is closed.
4. Within approximately 2 hours, pressure will start to build in the RO Filter System. Care-
fully inspect all connections and fittings while this pressure buildup occurs.
5. Check for leaks. If leaks are found, fix by ensuring all tubing is cut squarely and fully
inserted. Also confirm there are no scratches, dents or notches at tubing end. If there
are, squarely cut 1” off and re-insert.
Note: When RO Filter System is first pressurized, water may project from faucet air gap hole until air is
passed from RO Filter System.
PURGE
1. Open RO faucet and let water flow through system for 24 hours.
Note: Flow rate will be slow during this time.
2. Close RO faucet after purge is complete.
Note: Your RO Filter System is ready for use when purge is complete, however, you will not have filtered
water immediately. It takes 1-3 hours to completely fill the tank. The flow rate will be less than your
kitchen faucet. Water will run to the drain while the RO Filter System is filtering water – even when not in
use. This is normal. Water going to drain will stop
