INSTALLATION AND MAINTENANCE FOR THE FILTER/
REGULATOR MANIFOLD ASSEMBLY
The F/R manifold system comes in two sizes with two choices of threads and 
is designed for installation at point of use.  The system consists of a connection 
adapter block, a Filter/Regulator with auto dump valve for condensation, a 3-port 
pressure relief valve, an anodized aluminum manifold with quick disconnect cou-
plers and plugs.
The Filter/Regulator will allow you to set the pressure to the tools at 85 to 90 PSI, 
while the main system can run at 125 to 145 PSI, this helps reduce pressure drops 
when using a large volume of air.  The F/R unit will also remove any condensation 
from your air supply while fi ltering the air of contamination down to fi ve  microns.  
By only using brass and/or aluminum after the F/R unit you can eliminate any rust 
and contamination from getting into your air tools.  The F/R manifold confi gurations 
are as follows:

The smaller assembly (Fig. 1) has a 
3/8” air passageway and is capable of 
53 CFM.  These F/R assemblies come 
with three 1/4” NPT couplers and three 
1/4” NPT female plugs.  The larger assembly (Fig. 2) has a 1/2” 
air passageway and is capable of 106 
CFM.  These F/R assemblies come 
with four 3/8” NPT couplers, one 3/8” 
NPT female plug and three 1/4” NPT 
female plugs.

(Fig.3)
Drop LegBall Valve
The assemblies come completely assembled using three modular clamps.  The two 
outer modular T-clamps are designed for mounting the unit to the wall, so the weight 
of the unit is not supported by the connection pipe and adapter. 
Note:    Although the units ship with the layout direction of left to right, if the 
environment warrants it, the Filter/Regulator assembly can be setup to 
use in the opposite direction (from right to left). See Page 8 for detailed 
instructions on disassembly and re-assembly.
 TOOLS NEEDED
1.  4mm Allen key for 3/8” manifold assembly or 5mm Allen key for ½” manifold 
assembly
2. Pipe wrenches
3.  12” adjustable wrench
4.  2-1/4” concrete mounting screws or wall anchors
5.  Drill and drill bit needed for mounting assembly to wall
 PRE-INSTALLATION
1.  Before you start, verify the supply pipe is the same 
size as your adapter block.  It is also important 
that you have a drop leg in the supply line, (a 
drop leg is short pipe and end cap below the tee 
(black circle)) (See Fig. 3).  Also recommended is 
to have a ball valve added to allow the air supply 
to be shut off to the F/R manifold assembly for 
cleaning and maintenance.  
  CAUTION!
Turn off your air supply, so there is no pressure in the system.  
						

							6
  CAUTION!
The weight of the unit should not be supported by the supply piping.
If your piping is mounted fl at against the wall, and you cannot connect directly to 
the supply line, use one of the following options to install the Alpha
® F/R Manifold 
Assembly.
 OPTION 1:  ALPHA® ADAPTER AIR HOSE ASSEMBLY
The Adapter Hose Assembly can be used to make the F/R Manifold Assembly 
easier to install. (See Fig. 4)
NOTE:  Adapter Hose Assembly is only available for Part No. 1030-0022 (53CFM) 
and 1030-0023 (106CFM) F/R Manifolds.
The Adapter Hose Assemblies are made of ½” Flexzilla hose with ½” NPT male 
swivel fi ttings on both ends and come in 1ft, 2ft, and 3ft lengths.

 OPTION 2:  ALPHA®  MOBILE AIR HOSE ASSEMBLY
The F/R Manifold assembly can be mounted 
directly onto your stone layout frames and/or 
closer to the point of use with an Alpha
® Mobile 
Air Hose Assembly (See Fig. 5).
NOTE:  Mobile Hose Assembly is only available 
for Part No. 1030-0022 (53CFM) and 1030-0023 
(106CFM) F/R Manifolds.
The Mobile Hose Assemblies are made of ½” Flexzilla hose with ½” NPT male 
swivel fi ttings on both ends and come in 15ft to 40ft lengths.

OPTION 3: HARD PIPED 
(Unit can be hard piped for offset from the 
wall using two medium pressure brass 45° 
elbows and one hex or close nipple).
1.  Align unit to connect to the wall pipe. 
2.  Loosen the clamp connecting adapter block to 
the Filter/Regulator using an Allen key.
3.  Connect the adapter block to the supply line 
so it exits to the drop line and is parallel to 
the ground (See Fig. 6).  
NOTE:  The Adapter block should screw 
onto the pipe until it is tight and the bevel is on 
the top side. 
    
4.  Mark holes for the T-clamp screws. Disconnect 
System.  
5.  Drill holes per the enclosed template (template 
is located on the back cover of this manual) for 
your specifi c unit. (See Fig. 7)

Air Flow
(Left to Right) 6.  Place the Modular T-clamp onto the adapter block and align so it sits fl at 
against the wall.
7.  Level the Modular T-clamp and install a screw to support.  
8.  Check and make sure the rubber sealing ring is fl ush against the outsides. 
9.  Check and make sure the rest of the manifold assembly and clamps are 
fl ush to the wall.
10.  Install the remaining screws to secure the modular T-clamps.
11.  Connect to the air line. 
NOTE:  If using the Alpha® Adapter Hose Assembly, screw into the supply line 
and adapter block securely and rotate adapter block so the bevel is on the top 
side.
DISASSEMBLY & RE-ASSEMBLY 
All F/R Manifolds are assembled and shipped 
in the LEFT to RIGHT confi guration  (see 
photo) to be mounded on the right side of 
the air drop line.  F/R Manifolds which will 
be mounted to the left side of the drop line 
needs to be converted over to a RIGHT to 
LEFT confi guration.

1.  In order to mount the F/R Manifold on the LEFT side of the air drop line, you 
need to disassemble the unit and re-assemble. Using a 4mm or 5mm hex 
key, loosen up the hex bolts on the Modular Clamps (#2 and #4) which will 
allow you to remove all the components of the F/R Manifold.  (See Fig. 10)
 NOTE: 
1.  4mm hex required for the 3/8” Manifold Assembly               
2.  5mm hex required for the 1/2” Manifold Assembly
2.  After all components are de-
tached, line up all the components 
in the reverse direction as the 
original assembly.  (See Fig. 11)
3.  The Filter/Regulator and 3-Port 
Relief Valve have air direction 
indication markings, make sure 
when reassembling for a  RIGHT 
to LEFT confi guration that the air 
direction indication markings on these 
components matches the new air fl ow 
pattern. (See Fig. 12)
NOTE: The F/R gauge will get turned around to face up once the re-assembly is 
complete

CHANGING THE FILTER/REGULATOR TO A RIGHT TO LEFT 
CONFIGURATION
1.  Now that the Filter/Regulator Assembly has been changed to a RIGHT to LEFT 
confi guration, the pressure gauge needs to be removed and re-attached to the 
backside of the Filter/Regulator. 
2.  Remove the clear plastic cover by 
twisting it clockwise, remove the two 
screws securing the pressure gauge to 
the Filter/Regulator. (See Fig. 13)
3.  Remove the pressure gauge by pulling it 
out of the Filter/Regulator. (See Fig. 14)
4.  Turn over the Filter/Regulator and 
remove the back cover by removing the 
two screws securing the cover to the 
Filter/Regulator. (See Fig. 15)
5.  Insert the pressure gauge into the Filter/Regulator making sure the pin 
on the back side of the pressure gauge fi ts into the pressure release hole 
within the Filter/Regulator (See Fig. 16).  Secure the pressure gauge 
using the two screws.
6.  Re-attach the clear window cover turning 
counter-clockwise to tighten and re-
attach the back cover and secure with the 
two screws.  (See Fig. 17 and Fig. 18)
