Installation
Mount the Fluid Regulator
See F
. 1. Mount the fluid regulator (C) in a location 
close to the fluid dispense device. A mounting bracket 
(D) is supplied. See Dimensions on page 14 for mount-
ing information.
Grounding
The equipment must be grounded. Mount the regulator 
to a conductive mounting surface (E) which is con-
nected to a true earth ground. Follow local code. Graco 
Part No. 222011 Ground Wire and Clamp is available as 
an accessory. See F
Air Supply
The regulator’s air inlet fittings accept 5/32 in. (4 mm) 
OD tubing. Air pressure can be controlled manually or 
with electronic pressure controls.
Connections can be made in two ways:
Use separate high (A) and low (B) air pressure sup-
ply lines, connected as shown in F
Use a single air supply line and connect it to the 
high or low pressure air inlet fitting alternately, as 
desired.
Fluid Inlet Line
See F
. 1. Connect the fluid inlet line (G) between the 
1/4 npt(m) fluid inlet fitting and the fluid supply.
Install the following accessories in the order shown in 
F
. 1, using adapters as necessary.
Fluid filter (H): to filter particles from the fluid 
before it passes through the fluid regulator. 
Fluid drain valve (J): required in your system, to 
relieve fluid pressure in the fluid regulator. 
Fluid shutoff valve (K): shuts off fluid flow.
Regulated Fluid Outlet Line
See F
. 1. Connect the regulated fluid outlet line (F) 
between the 1/8 npt(f) fluid outlet port and the system’s 
fluid dispense point.
NOTE: All components located downstream of the fluid 
regulator must be rated for the maximum fluid inlet pres-
sure sent to the regulator. Do not use the regulator as a 
fluid shutoff valve.
Flush Before Using Equipment
The equipment was tested with a rust inhibiting test 
fluid. To avoid contaminating your system, flush the 
equipment with a compatible solvent before using the 
equipment. See Flushing, page 7.
