f) Place new filters in the plastic holding clips. Make the tubing connections into
the fittings. BUT DO NOT CONNECT THE OUTLET TUBING OF THE
2ND STAGE CARBON FILTER.
g) Open ball valve and let water flow through filters into a bucket or pan to push
out air and any carbon fines. When water runs clear, turn off ball valve and
connect 2nd stage filter to outlet line (orange).
h) After all connections are made, turn on ball valve and water flow to the water
dispenser will resume. Wait a few minutes to assure there are no leaks.
Replace front panel.
8.2 Stage 3 Reverse Osmosis membrane replacement, RO versions (R) (every 3 years)
a) Use the same procedure as in para. 8.1 above sec a-d.
b) Remove the RO stage from the clips. Disconnect the orange tubing from the
RO housing cap.
c) Remove the cap from the housing by unscrewing it.
d) Using a pair of pliers, remove the RO element from the housing by grasping
the tube end and pulling it out.
e) Use RO filter replacement P/N ma-4203 (50gpd TFC membrane). Insert the
element into the housing with double “o”-ring end going in first–toward the
bottom of the housing. Make sure the “o”-rings are sealed. Replace the cap.
Reconnect the orange tubing. Proceed as in para. 8.1, h.
F) Model PWC-3000 uses RO filter replacement P/N mh-4206 (75gpd TFC
encapsulated Membrane). This membrane is disposable, the housing and
membrane are integrated. To replace simply disconnect the tubing from the 3
quick connect fittings, (See pg. 9 figure 7) remove membrane from mounting
clips and discard old membrane. Install new membrane into mounting clips
and re-connect tubing to the quick connect fitting built in membrane housing.
NOTE: For mh-4206 Orange line connects to Green fitting- Feed water in.
Black line connects to the Yellow fitting - brine water out to drain, White
line connects to Blue fitting - clean product water to cooler tank
