2) Replacing the Air Filter
A. The air filter is located underneath the dispenser. While wearing sanitary gloves, slide the air filter out of the
dispenser.
B. Slide in a new air filter into the dispenser.
3) Replacing the 2 external All-in-One filters (HS-5441) and the internal alkaline
chamber (HS-5442)
Replace the two external All-in-One filters (HS-5441) and the alkaline chamber (HS-5442) when the filter life green
LED indicator blinks (i.e. it means that 6,000 gallons have been dispensed by the DWM-20A dispenser) or every 6
months, whichever comes first. Instructions are also found on the label of the All-in-One filter (HS-5441) and on the
label of the alkaline chamber (HS-5442). Follow this procedure step-by-step:
A. Locate the main water shutoff valve (the angle stop valve).
B. Shut off the water line valve (i.e. the angle stop valve) and relieve the water line pressure by selectively touching
the dispensing buttons until no more water comes out from the dispenser.
C. Locate the two All-in-One filters HS-5441.
D. Hold the head of each filter firmly. Rotate the cartridge clockwise, ΒΌ turn, and pull it out.
E. Insert a replacement cartridge by rotating it counter-clockwise, 1/4 turn, until it clicks and stops. The arrow on the
top collar should align with the arrow on the head.
F. Get a bucket or sink to flush filters: remove the water line from the back of the dispenser and re-open the water
supply so that the HS-5441 filters can be flushed out in a 5 gal. bucket or in the sink. Flush the filters for 5
minutes or until the water runs clear. DO NOT flush the filters through the dispenser.
G. When the two new HS-5441 filters have been flushed, shutoff the main water valve (angle stop valve) again and
locate the alkaline chamber HS-5442 inside the side panel door on the right side of the dispenser.
H. Unscrew and remove the panel to reveal the alkaline chamber.
