SETTING THE SYSTEM PRESSURE
1.  To setup and use the F/R unit after installation you need to turn on your air supply.

system for leaks.  Make sure the modular 
clamps are tight.
3.  To adjust and set the pressure, lift the gray 
knob on the top of the Filter/Regulator unit, 
so the orange ring is showing.  (See Fig. 22)

 AUTO DRAIN OPERATION
This Filter/Regulator is equipped with an auto drain.  This auto drain is normally 
open, therefore when you start your compressor in the morning and your pressure 
starts to rise, a small amount of air will come out of the drain and remove any 
condensation from the bowl.  
Once the system pressure rises above 15 PSI, the auto drain will close.  When the 
system is at operating pressure and the bowl fi lls up with water, the fl oat will rise and 
open the drain, this will release...

 INSTALLATION AND ADJUSTMENT 
Warning: Note arrow on the front of the 
3-Port Relief Valve, only clean and fi ltered air 
should be supplied to Port 1.  Port symbols are 
cast into the housing (See triangle in Fig. 24) 
  CAUTION!
The valve must be switched to each position instantly and securely. Stopping the 
knob between the extreme positions may cause a malfunction.

 BOWL AND AUTO DRAIN CLEANING
The F/R unit is equipped with a NO (normally open) auto drain.  When pressure is 
turned off to the unit, the drain will open and water will drain out the bottom.  
When you turn on your compressor and the pressure starts to rise air will vent any 
condensation out of the drain until the system pressure rises above 15 PSI. 
If you do not hear this venting when starting, your auto drain should be checked 
and cleaned.
 MANUAL DRAIN

 CLEANING THE BOWL
If the water in the bowl is rising above the fl oat your drain is clogged and needs to 
be cleaned.  Turn the air off to the assembly and depressurize the system.  
When the pressure gauge reads zero, remove the bowl and rinse with soap and 
water to remove the sediment at the bottom of the bowl.  
Because the auto drain is normally open water should fl ow through the drain.  If 
water is still not draining try blowing air into the bottom drain port to clear out the 
clogs and...
