Mixing Module and PCD Installation
TOOLS REQUIRED
•
5/16” Spintite (P/N 0904A)
•
3/8” Open-End Wrench
•
5/8” Open-End Wrench
NOTE:
Always lightly grease threads
that come into contact with
chemicals.
1.
INSTALL THE MODULE- Without connecting the gun to the chemical hose,
connect the air supply to the gun. Move the safety to the “Open “ position. Holding
down the gun trigger, place the module over the tip of the valving rod. Align the
keying pin with the hole in the gun block and push in firmly. Install the module
retainer finger tight and release the trigger. Using the 5/8” Open-End Wrench,
tighten the retainer firmly (do not over tighten).
NOTE:
Tighten the PCD Retainer
finger tight only.
2.
INSTALL THE PCD- Using the 3/8” Open-End Wrench, loosen the Rear Seal
Retainer Assembly slightly. Remove the Safety Stop from the gun. Using the 5/16”
Spintite and 3/8” Open-End Wrench, loosen the Locknut and screw the Valving Rod
rearward as far as it will go. Place the PCD over the Mixing Module Retainer.
Install the PCD Retainer and tighten by hand. With the gun in the closed position
(air supply connected), insert the 5/16” Spintite through the rear of the gun and
advance the Valving Rod forward to engage the PCD. When you feel the rod contact
the PCD, tighten another 1/10 of a turn. While holding the rod in position, tighten
the Locknut against the piston shaft until snug. Retighten the Rear Seal Retainer
Assembly.
3.
CHECK ADJUSTMENT OF THE PCD- Hold down the gun trigger, loosen the PCD
Retainer, then release the trigger. Tighten the PCD Retainer and, while maintaining
the tightening torque, trigger the gun. The retainer should suddenly rotate
approximately 1/10 of a turn. Release the trigger. The adjustment is now complete.
Start-Up
TOOLS REQUIRED
•
5/16” Spintite (P/N 0904A)
IMPORTANT: Before attempting the following procedures, make sure the gun is
attached to the coupling block and air hoses, the proportioning unit is at the desired
temperature and pressure, and the system is ready for operation.
1.
ADJUST THE AIR CAP ADJUSTMENT VALVE- The knurled knob on the left
side of the Air Cylinder controls the amount of air that passes over the PCD. This
flow of air helps keep the PCD free of sprayed chemical. Too much air can
adversely effect spray pattern shape and create undesirable amounts of over-spray.
However, the airflow can be used to modify the spray pattern. Experiment to
determine what works best for the application.
Turn the knob Counter clockwise to open the valve and clockwise to close it.
2.
OPEN BOTH MANUAL VALVES- Using the 5/16” Spintite, turn each valve
counter clockwise approximately three full turns.
3.
DISENGAGE THE SAFETY STOP- Push in and turn the Safety Stop counter
clockwise to place the gun in the Open position (The Red Band will be exposed).
4.
TEST SPRAY- Trigger the gun on a disposable surface and evaluate.
