INSTALLATION
M6, M6X, M18-M20
1. Unpack motor and pump tube from carton. Check for shipping damage. If damage is detected, save the packaging and notify
the carrier immediately.
2. Ensure motor and pump compatibility. I.E., labeling.
3. If motor and pump tube are boxed separately, the motor will need to be fastened to the pump tube.
4. Ensure no obstructions on the coupling of either motor or pump/mixer.
5. Position the pump tube upside down onto the motor. The ball valve & muffler should be aligned with the discharge spout
for ease of operation.
6. Slide pump/mixer down into motor until couplings mate and pump/mixer is seated properly.
7. For M6 & M6X, install 2 socket head screws and nuts in mounting holes and tighten securely. For M18, M19, and M20 tighten
set screws.
8. Check to ensure that the motor is secured to the pump/mixer before operating. If not, repeat steps 1-7.
9. ALWAYS use an automatic air line lubricator, moisture trap and filter in the airline ahead of an air motor. (Use detergent SAE
#10 in lubricator). Do not exceed 80 psi (551 kPa) on M6 and 100 psi (689 kPa) on all other air motors.
OPERATION
1. Turn the air motor ball valve to the closed position.
2. Attach the air motor to an air supply line.
3. Insert the pump tube into the fluid to be dispensed and the hose in the container to be filled.
4. While holding the air motor ball valve and hose, slowly turn the valve to the desired flow rate. (Note: Pump performance will
vary depending on air pressure & volume.)
1. Check the rotation direction of the LR motor (air and induction motors) before installing the motor onto the pump.
WARNING: Motor rotation must be clockwise when viewed from the fan end of the motor. Rotating the motor in the
wrong direction will cause damage to the pump.
2. Remove the motor adapter bolts (see Figure 2) and separate the motor adapter from the motor.
3. Thread the motor adapter onto the LR drive assembly. Hand tighten the motor adapter.
Note: Threads are left-handed. Also, thread lubricant is recommended to ensure smooth, bind free assembly.
4. The LR motor coupling consists of two 5/16” diameter pins welded to a hub. The LR drive assembly coupling has
two slots that receive these pins. Align the pins of the motor coupling with the slots on the drive assembly coupling
and slide the motor onto the drive assembly.
Note: Make sure the coupling is engaged properly and the motor adapter face is flush with the motor face.
5. Rotate the motor until the motor adapter mounting holes align with the threaded holes in the motor face.
6. Install the motor adapter bolts and torque to approximately 7 ft.-lbs. (9.5 N•M)
REMOVAL - HVDP-LR:
1. Remove the LR motor adapter bolts.
2. Remove the LR motor.
