INSTALLATION GUIDE

STEP 7 - Filter installation
Before you begin: Ensure the cold water valve is shut off and there is no pressure in
the System. Carbon (green caps with clear netting) and Claryum
blue netting) filter cartridges will come pre-installed in their cartridge sumps.
1
Attach Carbon sump to the First Stage
position on the inlet side of the System
Manifold. Ensure all connection points
are aligned and push the top of the
sump up and into the System Manifold.
Turn the sump towards the right until
it locks.

Repeat step 1 for the Second Stage
RO Membrane that fits in the center,
and for the Claryum cartridge in the
®
Third Stage position on the outlet side
of the System Manifold.
STEP 8 - Sanitize, Test & Purge
Sanitize
1
Disconnect white tubing from the
Manifold outlet labeled "Tank" .
2
Add 3ml household bleach (5.25%)
into disconnected end of white tubing
using eyedropper (included).
Note: Handle bleach according to
manufacturer's instructions.
3
Using the white tube, reconnect the
Tank to the Manifold outlet labeled
"Tank" . Push tubing in all the way.
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
In approximately 2 hours, pressure will
start to 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.
Note: When RO Filter System is first pressurized,
water may project from faucet air gap hole
until air is passed from RO Filter System.
Note: Sanitization is recommended
immediately after RO Filter System
installation and any inner-part servicing.
The person sanitizing must have clean
hands during this process.
IMPORTANT: Complete sanitization prior to pressure test.
Purge
1
Turn on RO 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.
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 automatically
when Tank is at capacity.
