STEP 8 Sanitize, Test, and Purge
Before you begin
Sanitization is recommended immediately after RO Filter System installation and any
inner-part servicing. The person sanitizing must have clean hands during this process.
Sanitize
1. Disconnect white tubing from the
manifold outlet labeled "Tank".
2. Add 3 ml household bleach (5.25%)
into disconnected end of white tubing
using eyedropper (I).
Note: Handle bleach according
to manufacturer's instructions.
3. Reconnect white tubing to system
manifold outlet labeled "TANK".
4. 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
1. Turn on COLD water supply valve
to RO Filter System.
2. Turn on kitchen faucet to purge air
from system. Turn off when water
runs smooth.
3. Confirm RO faucet is closed.
4. After 2 hours, pressure will build in the
RO Filter System. Carefully inspect all
connections and fittings while pressure
buildup occurs.
5. Check for leaks. If leaks are found,
ensure all tubing is cut squarely and
fully inserted. Confirm there are no
scratches, dents or notches at tubing
end. If so, squarely cut 1" off of
tubing and re-insert. If leaks are still
happening, refer to trouble shooting
guide.
Note: When RO Filter System is first
pressurized, water may project from
faucet air gap hole until air is passed
from RO Filter System.

Important: Complete sanitization
prior to pressure test.
Purge
1. Turn on designated faucet and let water
flow through system for 24 hours.
Note: Flow rate will be slow at this time.
2. Turn off RO faucet after purge
is complete.
IMPORTANT
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 the drain will stop
automatically when tank is at capacity.
