RO-QUICK90 System Filter Change Instruction
How To Replace Stages 1, 2 Pre-Filters:
Turn OFF cold water supply to RO system. Turn OFF tank’s ball-valve. Turn ON the RO faucet briefly to
relieve the built-up pressure inside the RO system. This will make opening the housings easier.
*Please remove red locking clips from Stage 1 & 2 tubing connection parts before replacing Stage 1 & 2
filters.
The Stage-1 Sediment filter is tucked between stage 2 & 4 CT-24CAB filters (see Fig. 1). For ease of ac-
cess, please tilt the filters to a convenient position then do the following:
Step 1. Disconnect tubing from Point A & Point I, discard used filter.
Step 2. Snap on the new filter onto the 2 holding clips. Make sure the Flow direction “arrow ”
on the filter is pointing toward the output direction Point I. Re-connect tubing securely to both ends
of the new filter.
The Stage-2 Pre-Carbon filter is located above the 3rd stage membrane filter (See Fig. 1). For ease of
access, please tilt the filters to a convenient position then do the following:
Step 1. Disconnect tubing from Point B & Point K. Discard used Filter.
Step 2. Snap on the new filter onto the 2 holding clips. Make sure the Flow direction “arrow ”
on the filter is pointing towards the output direction Point B. Reconnect tubing to both ends of the
new filter.
*Please re-install red locking clips from Stage 1 & 2 tubing connection parts after tubings are connected to
the filters.
