1. Ensure that you have selected the correct tubing size for the application.
WARNING: Turn off the system before removing or installing tubing. Disconnect the pump drive from the AC
source to prevent accidental starting of the drive mechanism. Fingers or loose clothing can be
caught in the pump mechanism, causing serious injury.
2. Make sure that the power switch is turned off and the pump drive is disconnected from the power source.
3. For the RD-1: Loosen the two knurled nuts holding the clear plastic cover, and slide the cover off the pump head.
For the RD-2: Remove and retain the four knurled nuts holding the clear plastic cover, and remove the cover from the
pump head. Remove and retain the two thumbscrews that secure the tubing clamp, and remove the clamp.
4. FOR TUBING LINKS:
NOTES: The tubing links for RD-1 and RD-2 come with washers that need to be placed outside of the pump. The
washers ensure a snug fit in the pump.
Tubing links are not available for number 18 (5/16 in. ID) tubing.
a. Refer to the instruction sheet that came with the tubing link. Refer to Figure 8, and align the tubing link to its path
through the pump head, ensuring that the mounting washers of the link are as close as possible to the outside of
the pump head.
NOTE: The male connectors on the tubing links are removable. Rotate each a half turn counterclockwise to remove
the connector, and a half turn clockwise to reinstall the connector.
b. Attach input and output ends of the transfer tubing to the connectors of the tubing link.

c. Manually rotate the roller assembly while guiding the tubing between the rollers and the pump head wall. Ensure
that the tubing is in the center of the channel.
5. FOR TUBING:
a. Insert tubing between the rollers and the pump head housing in the center of the channel, midway between the
clear plastic pump head cover and the pump head housing bottom. This ensures that the rollers depress the
entire width of the tubing as they turn.
b. Feed the tubing in, and manually rotate the roller assembly. Guide the tubing between the rollers and the pump
head wall.
c. Pull gently on the input and output sides of the tubing to create a gap between the tubing and the curved pump
head housing wall.
There should be a small but visible gap between the tubing and the pump head housing for about 1/3 to 1/2 of the
contact surface at any time.
NOTE: The clear plastic pump head cover is reversible on the RD-1 models. It has different size tubing retainers on
each face. If the tubing is smaller than 3/16 in. ID, place the cover so that the larger tubing retainers hold the
tubing. If the tubing is 3/16 in. ID or larger, reverse the cover.
