Replacing The Pump Or Actuator Module
The rotospray pump consists of a pump module (part no. 983117) and an actuator module (part
no. 983116). In most cases, the pump module is the one replaced.
WARNING: Failure to correctly change out the pump module(s) will result in DAMAGE.
No tools are required to connect or disconnect the pump from actuator. If any forceful effort is
required, the assembly is not correct and the instructions should be reviewed.
To Disassemble
1. Shut off air supply and relieve pressure from air lines.
2. Disconnect the air lines and product feed lines from the pump module. Elevate the feed line
above the reservoir to prevent product leakage from the feed line.
3. Position and hold the pump assembly so that the stroke adjuster knob is facing you with air
line connectors pointing straight up (12 o’clock).
4. Rotate the stroke adjuster knob counterclockwise to the full open position.
5. Rotate the knurled black locking ring clockwise by hand until it bottoms out or stops turning.
6. Gently push the pump module towards the actuator module and rotate the pump module
clockwise approximately 90 degrees until it stops.
7. Disengage the pump module from the actuator module by pulling them apart.
To Assemble
1. Push stroke adjuster knob in to advance pin connector.
2. Carefully position a new pump module onto the actuator module; the feed line connector
should be at (3 o’clock) position, and push together until fully seated.
3. Rotate the pump module counterclockwise approximately 90 degrees or until it stops.
4. Rotate the black locking ring by hand counterclockwise until tight against face of the actuator.
5. Reconnect product feed lines and air lines to pump assembly and set stroke adjuster knob to
dispense desired amount.
