Installing Kit 238–141 Kit 238–141 converts Model 236–465 airless sprayer into Model 238–140 air-assisted airless sprayer. NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the parts drawing on page 3. Read this entire manual before assembling the unit.
WARNING Separate manuals are supplied with the components of your sprayer. Read and understand all instruction manuals before operating. Never exceed the Maximum Fluid Working Pressure and Maximum Air Input Pressure for these sprayers, given in the Technical Data on page 7. Never exceed the maximum working pressure of the lowest rated component in your system. Be sure that all fluids and solvents used are chemically compatible with the wetted parts shown in the Technical Data on page 7, and in the separate component manuals.
WARNING If you are installing Kit 238–141 on a previously operated sprayer, be sure to follow the Pressure Relief Procedure in your separate pump manual before beginning the following procedure. 1. If you are installing the kit on a sprayer that has previously been operated, relieve the pressure.
2. Remove the nut and lockwasher (C) holding the air manifold (D) to the mounting bracket (E). Pull the manifold up off the bracket. 3. Remove the air manifold (D) from the pump air regulator (F). 4. Screw the tee (3) into the pump air regulator (F), as shown. Screw the air manifold (D) into the tee. Reinstall the air manifold on the mounting bracket (E) and secure with the lockwasher and nut (C). 5. Install the gauge (7) in the gun air regulator (6). Install the 1/2 npt nipple (5) in the regulator’s inlet port, and the reducing nipple (8) in the outlet port. 6. Install the 90 adapter (4) in the branch of the tee (3), and connect the gun air regulator nipple (5) to the swivel. Tighten securely. Use this air regulator to control air pressure to the gun. 7. Screw the gun swivel (12) onto one end of the fluid hose (10), then connect it to the gun (13) fluid inlet, as shown. Connect the air hose (9) to the gun air inlet. The hoses are tied together for ease of movement when spraying. 8. Connect the air hose (9) to the reducing nipple (8) at the gun air regulator outlet (A). 9. Connect the fluid hose (10) to the fluid filter outlet (B), using the reducing nipple (16). 10. Operate the sprayer as described in the separate sprayer, pump, and gun manuals.

Installing Kit 235–853 Kit 235–853 converts Model 237–399, 224–619, and 224–617 airless sprayers to Model 237–405, 231–303, and 231–302 air-assisted airless sprayers.
2. Remove the nut and lockwasher (C) holding the air manifold (D) to the mounting bracket (E). Pull the manifold up off the bracket.
NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the parts drawing on page 5. Read this entire manual before assembling the unit.
3. Remove the air manifold (D) from the pump air regulator (F). Disconnect the air hose (G) from the bleed valve (H).
WARNING Separate manuals are supplied with the components of your sprayer. Read and understand all instruction manuals before operating. Never exceed the Maximum Fluid Working Pressure and Maximum Air Input Pressure for these sprayers, given in the Technical Data on page 7. Never exceed the maximum working pressure of the lowest rated component in your system. The relief valve (supplied) opens automatically to relieve air pressure to the pump if the pressure exceeds a preset level. This valve prevents overpressurization of the hose and gun. Be sure that all fluids and solvents used are chemically compatible with the wetted parts shown in the Technical Data on page 7, and in the separate component manuals.
WARNING If you are installing Kit 235–853 on a previously operated sprayer, be sure to follow the Pressure Relief Procedure in your separate pump manual before beginning the following procedure. 1. If you are installing the kit on a sprayer that has previously been operated, relieve the pressure.
