APEC R.O. Lite Commercial System Filter Change Instruction

How To Replace Stages 1, 2, 3 Pre-Filters: (FILTER-SET-LITE)

1) Turn OFF cold water supply to RO system. Turn OFF tank’s ball-valve. Lift up RO faucet lever briefly

to relief the built-up pressure inside the RO system. This will make opening the housings easier.

2) Open housing: Have the RO standing upright. Slip the plastic wrench onto the #1 housing. Looking

down from a top view, you should open the housing turning clockwise. If necessary, lay the RO down

on the floor to get a better leverage. If the housing is too tight, use a hammer and tap on the wrench

handle to help turn the wrench.

3) Discard 3 used filters, wash housings with mild soap, rinse off. Put 3 new filters into their respective

housing: sediment filter in stage-1, carbon block filter in stages 2 & 3.

4) Close up the housing. Make sure each housing has a black O-ring in the thread groves. Use wrench

to tighten each housing.

5) Remember: Turn ON the cold water supply and OPEN the tank valve after you finished

changing filters!

6) Check for leaks!

How to Replace Stage-4 Membrane: (MEM-90)

There are several membranes (2 to 4 depending on model) provided with your system. Please

insert the membrane into each housing one-by-one to prevent mis-connecting the tubing.

The number of housing matches with the number of membranes provided. Each housing is

labeled as: “MEM-1”, “MEM-2”, “MEM-3”, “MEM-4” depending on your RO model.
