Changing Stage-6 PH Filter: (should be changed every 6 months).
NOTE: The QC fittings come with an End Plug that needs
to be removed before the tubing can be connected.
See Fig. C
1) Turn OFF cold water supply to RO system. Turn OFF tank ball-valve by turning the blue handle 90 degrees. Turn on RO
faucet briefly to relieve the built-up pressure inside the RO system. This will make removing the tubing easier.
2) Remove the CLEAR outlet tubing at point P See Fig. B. To remove the tubing, Push In and hold down on the collet ring
square against the fitting. With the collet held in this position the tubing can be removed. Once the outlet tubing is discon-
nected, please remove the inlet tubing at point O. Remove old filter and discard.
3) The new PH filter will come with 2 End Plugs. Please remove the plugs before connecting the tubing to the filter.
4) To reconnect the tubing to point O and P, push the tubing into the Quick Connect fitting, then gently pull back on the
tubing to make sure the connection was secure. Make sure “FLOW “ on filter is pointing to the drinking water faucet.

Changing Stage-5 Carbon TCR Filter: (should be changed every 2-3 years). The new stage-5 carbon filter
(5-TCR-QC) includes a new Tee Fitting on one end. The stage-5 filter is easily replaced by disconnecting the tubings
from the old filters, and connecting the filter.
1) Remove the OLD filter: See Fig. B. Disconnect the output tubing from point H and tubings at point G & F. To remove
the tubing, Push In and Hold Down on the collet ring square against the fitting. With the collet held in this position the
tube can be removed.
2) Unclip the old filter from the membrane housing and discard the used filter.
3) Sanitize: Use some mild bleach solution to rinse the 1 plastic port of the Tee fitting and the open port of the new filter. This is
to prevent contamination.
NOTE: Only this filter change needs bleach sanitizing. Do Not apply chlorine/ bleach in any way to Membrane for it will
damage the membrane!
4) Connect New Filter: See Fig. B. Attach the new filter onto the clips. Make sure the “FLOW ” arrow on the filter is
pointing towards the pure water output direction. Reconnect the tank yellow tubing and clear tubing from C4 back to point
G & F on the Tee fitting. Then, connect the output tubing to point H.
5) Check for leaks!
