Rubber
Seal
6. Insure rubber seal is in place in the
center of the flat stem (See Figure 11).
If the seal comes out, press it back in
place in the recess of the stem.
7. Replace the float cap (again, be certain
the rubber seal, Figure 11, is in place).
8. Slide float over float guide.
9. Snap float cover onto bottom piece.
10. Install automatic drain into bowl. Be
sure O-ring is in place (between the
drain and bowl). Tighten the plastic
retaining nut firmly by hand.
11. Monitor the automatic drain for proper
operation. If it fails to operate properly,
replace with a new unit.
Note
If the Float Guide inadvertently
came apart, refer to Figure 12 and
instructions.
3. Slide flat off flat guide (See Figure 9).
4. Using a knife edge, carefully pry off
flat cap (See Figure 10).
5. Clean inside of flat. Remove all traces
of water or dirt.
Note
The automatic drain includes a float.
If water gets into the float, the auto-
matic drain may not function properly.
Under normal conditions, water will
not enter the float. However, water
can get in the float if the filter bowl
is washed with the drain installed or
if air line contamination causes the
drain mechanism to stick.
You can confirm the automatic drain is not
operating if the water level in the plastic
bowl is higher than the top of the automatic
drain.
To remove water from the float, follow these
instructions. Be careful not to lose or damage
any internal parts of the automatic drain (re-
placement parts are not available - complete
drain replacement will be necessary).
1. Remove automatic drain from plastic
bowl by loosening plastic retaining
nut. Keep retaining nut and O-ring for
reassembly later.
2. Using a knife edge, carefully pry apart
the float cover and bottom piece (See
Figure 8).
