APEC Reverse Osmosis (RO)-45 System Filter Change Instruction

Changing Stages 1, 2, 3 Pre-Filters:  (should be changed at least every 12 months)

  1. Turn OFF cold water supply to RO system.  Turn OFF the tank 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 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 housings:  sediment filter in stage-1, carbon block filters in stages 2 & 3.
  4. Close up the housings. 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 finished changing filters!
  6. Check for leaks!

Changing Stage-4 Membrane:   (should be changed every 3-4 years)

  1. Turn OFF the cold water supply to RO system.  Turn OFF the tank 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. See Fig. A. Locate the Membrane housing on the system (labeled “Membrane”).  Remove the RED tubing from the housing’s cap at point D.  Do so by unscrewing the plastic nut (not the L-shape fitting) and pull out tubing. Open up the cap (turn counter-clockwise).  Remove the used membrane. Discard. Insert the new membrane using a pair of pliers. Push membrane into housing tightly. Avoid touching the Membrane with your hands to prevent contamination!
  3. Important!  Make sure the “double-ring” end of the membrane goes into the housing first as shown in Fig. B. below. The membrane cannot filter water if it’s inserted in the WRONG direction!
  4. Close the housing cap. Reconnect the RED tubing to the cap. Turn on the cold water supply and open the tank valve.  Let the RO system run to re-fill the tank (takes about 2-3 hours).
  5. Check for leaks!
  6. Drain the first tank of water (through faucet) to flush out the new membrane! The 2nd tank of water is ready for use.

Changing Stage-5 Carbon TCR Filter: (should be changed every 3-4 years with Membrane)

  1. Remove the OLD filter: See Fig. A. Disconnect the output tubing from point H.  Remove the fitting from the filter’s Right hand port. Remove the T-fitting from filter’s Left hand port (Points G & F). You will put these 2 fittings on the new filter. Discard the used filter.
  2. Sanitize: Use some mild bleach solution to rinse the 2 plastic fittings, the 2 tubing ends, and the 2 ports of the new filter. This is to prevent contamination.
  3. Connect the 2 fittings and tubing to the new filter as before.  Make sure the “FLOW –> on the filter is pointing to the pure water output direction. NOTE: Only this filter change needs bleach sanitizing.  Do Not apply chlorine/ bleach in anyway to Membrane for it will damage the membrane!
  4. Check for leaks!
