7.  The Bowl assembly needs to be 
reversed so the “bowl lock” is located 
on reverse side.  Press down on 
the bowl lock tab and turn the bowl 
either to the left or right to loosen and 
remove. (See Fig. 19 and 20)
8.  Continue connecting all the components together (Filter/Regulator, 3-Port 
Relief Valve, Modular Piping Adapter, Black Anodized Manifold) using the 
Modular T-clamps. Go back to make sure each hex screw is fully tightened.  
The arrows on the F/R Manifold System now points in the direction Right 
to Left.
PROTECTING THE F/R MANIFOLD SYSTEM
NOTE:   If the unit is mounted 
in an area where water and 
stone slurry can contact the 
unit, it should be covered 
with plastic (See Fig. 21).  
The plastic fi lm below can be 
purchase from Alpha
® Part # 
1030-1140, size: 16”x16”.

SETTING THE SYSTEM PRESSURE
1.  To setup and use the F/R unit after installation you need to turn on your air supply.
2.  Open up the recommended ball valve in the supply line and check the manifold 
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) 
4.  Turn the knob clockwise to increase (+) the 
pressure, and counter clockwise to decrease 
(-).  When running an Alpha
® Air Polisher the 
regulator should be set to 90 PSI, with the line drop 
through the fi lter with the outgoing pressure to the air 
polisher to be 85 PSI.  
5.  Push the knob back down to lock the pressure at 
that point.
  CAUTION!
NOTE:  Alpha® recommends that you supply each AIR-680 polisher with 
15 CFM, and the PSC-150 with 32 CFM for them to run with the 
correct torque.  
If your system is sized correctly you will still see a 5 to 8 PSI drop 
in pressure for each AIR-680 polisher, and a 10 to 15 PSI drop in 
pressure when running the PSC-150 stone cutter, this is due to the 
pressure drop through a clean 5 micron fi lter element. 
If upon initial use you see a larger pressure drop than stated above, 
your air compressor is undersized and not able to supply the volume 
(CFM) of air needed. 
Over time you will see an additional 5-10 PSI drop in pressure when 
running 1-3 tools. as the fi lter element becomes dirty and needs to 
be replaced
.

 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 the standing water, and the drain will close again.  
At the end of the day when your compressor is turned off and the system pressure 
drops below 15 PSI, the auto drain will open again and allow any condensation in 
the bowl to drain out.
 3-PORT RELIEF VALVE
A 3-Port Relief Valve has been added to the system to allow you to quickly turn off 
the air and depressurize the manifold block and connected lines.  When your tools 
are not being used they should be disconnected from the system or the system 
should be depressurized.
1.  Turn the red knob on the top of the 3-Port Relief Valve to 
SUP (SUP = Supply), in the direction as indicated on top 
of the red knob.  SUP should show up in the window on 
the front of the relief valve.  Your system is now pressur-
ized. (See Fig 24)
2.  Turn the red knob on the top of the 
3-port relief valve to EXH (EXH = 
Exhaust), in the direction as indicated 
on top of the red knob.  EXH should 
show up in the window on the side of 
the relief valve.  Your system is now 
depressurized. (See Fig. 25)
NOTE:  An optional silencer can be added to port 3 to silence the exhaust during 
depressurization (silencer for the 3/8” assembly is part # 1030-1185, the silencer 
for the ½” assembly is part # 1030-1186).(Fig.24)
(Fig.25)
A lock can be 
added to 3-port 
relief valve 
during serving 
of downstream 
equipment 
to prevent 
accidental 
pressurization.

 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.
SYSTEM MAINTENANCE
 FILTER REPLACEMENT
Warning: Over time, your fi lter will get clogged and need to be replaced.  Replace 
the element every two years or when you see an additional 10 PSI drop in pressure 
when you are running a tool.  A dirty fi lter can also be indicated by the fi lter  turning 
red or yellow from contamination.  Please note: normal operating pressure drop for 
one tool can be 5 to 10 PSI, so when the pressure is dropping 15 to 20 PSI, the fi lter 
should be replaced.  Replacement fi lters should be ordered and kept on hand.  The 
unit should never be used without a fi lter.
To replace the fi lter, turn off the recommend ball valve installed in the supply line before 
the unit.  If a ball valve was not installed, you will need to shut down your air system 
and empty the line pressure.  When the pressure gauge reads zero, pull down on 
the bowl lock (circled on Fig. 28) and rotate Bowl left or right while pulling down.  The 
Bowl will separate from the housing in the position shown. (See Fig. 26)
Turn the fi lter lock (black part at bottom of fi lter (Fig. 27)) ½ turn counter-clockwise to 
unlock.  Remove and replace fi lter, reinstall fi lter lock, line up the pins in the slot and 
½  turn clockwise.  Filter should be tight in the housing.
Reinstall bowl and make sure bowl lock is recessed in the groove.

 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
If the auto drain is not working correctly, you can 
manually open the drain cock and release any 
condensation from the bowl.  
Turn the knob on the bottom half of the drain 
cock clockwise two to three turns to open.  This 
will manually open the drain, but if the drain 
ports inside the bowl are clogged the water and 
condensation may not be released.  (See Fig. 29)
(Fig.28)
(Fig.29)
  CAUTION!
(Fig 26) (Fig (27)
When the bowl is installed on 
the F/R, it should be so that 
the lock button lines up in the 
recessed groove on the front 
of the body to avoid the bowl 
being dropped or damaged 
when pressure is applied. 
						

							16
 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 sediment. 
If the auto drain is still not working correctly after cleaning, the bowl assembly 
should be replaced.  Alpha
® only sells the complete bowl assembly with auto drain, 
you cannot purchase the auto drain or parts separately.
