Warnings
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
NOTE: The following warning applies only to Models 214018, 208250, 214019, and 210097, which contain aluminum housings.
WARNING
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious chemical
reaction and equipment rupture. Failure to follow this warning can result in death, serious injury, or property damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material supplier for compatibility.

Installation
Installation
Connect the Fluid Hose
Regulators or Circulating Adapters
• Connect the fluid hoses to the 1/4 npsm(m) inlet and
return fittings.
Straight Adapter
• Connect a hose to the 3/8 npsm(m) inlet fitting.
Connect the Regulator or
Adapter to the Gun
Model 223622
• Screw the regulator union adapter onto the gun fluid
inlet.
Models with Twist-lock Couplers
• Screw the coupler stem onto the gun inlet. Connect
the twist-lock couplers by lining up the coupler slots
with the pins on the stem, pushing the coupler onto
the stem, then twisting the coupler clockwise to lock
it.
Service
To reduce the risk of serious injury, including
splashing in the eyes or on the skin, always shut off
the air and fluid pressure to the gun and trigger the
gun to relieve pressure in the hoses before
disconnecting hoses from the regulator or adapter.
To Clean or Service the
Regulator
1. Relieve the air and fluid pressures.
2. Disconnect the regulator from the gun and the
hoses from the regulator.
3. Disassemble the regulator. Refer to the Parts Drawing.
4. Clean and inspect the parts carefully.
5. Replace worn or damaged parts and reassemble
the regulator. Be sure the nylon side of the diaphragm (12) faces the fluid.
Torque Notes:
Models with Slip-ring Couplers
• Pull the slip ring back as you push the coupler onto
the stem.
Operation
NOTICE
To avoid damaging the regulator diaphragm, never
exceed 200 psi (1.4 MPa, 14 bar) Maximum Inbound
Fluid Pressure to the regulator.
To Adjust the Fluid Pressure
Trigger the gun. Turn the fluid regulator setscrew (2)
clockwise to the desired setting. Release the gun trigger, tighten the locknut (1), and install the acorn nut
(16).
Diaphragm Nut (3) onto Valve Stem (8):
6 to 10 in-lb (0.7 to 1.1 N•m)
Screws (5) into the Housing (18):
20 to 30 in-lb (2.3 to 3.4 N•m)
Cap (14) into the Housing (18):
10 to 15 ft-lb (13.5 to 20.0 N•m)
