KR2i / KMPi TFF Systems
Pump Head Setup and Operation
pump head should be tilted about 30° counterclockwise from the intended installed
orientation. Press pump head firmly against the drive and rotate clockwise until no more
rotation is possible (see Figure 4). The bayonet lock lever will automatically snap toward the
back of the pump, locking it to the mounting plate
3. Remove the pump head from the drive by holding the bayonet lock lever forward while
rotating the pump head as far as possible in the counterclockwise direction, then pull the
pump head away from the drive to detach it. The actuator lever should be in the far right
position when removing the pump head (see Figure 5)
KR2i Tubing
WARNING: Stop the pump drive before installing or removing tubing from the pump head.
1. To load tubing, open the pump head by moving the actuator lever counterclockwise (see
Figures 5 and 6). Insert a loop of tubing into one open tubing retainer, between the
occlusion bed and the rollers and into the other tubing retainer (see Figure 7). Position the
tubing so that it is firmly centered against the rollers. While holding the tubing ends, move
the actuator lever back to the far clockwise (right) position, as shown in Figure 5. The pump
head will automatically grip the tubing. Approximately 5 pounds of force must be applied to
the actuator lever to fully close the pump head and place the lever in its locked position (far
right position) or to fully open the pump head (far left position)
NOTE: It is unnecessary to have an end of the tubing free to load or unload tubing from the pump
head. A length of tubing may be loaded into the pump without disconnecting it from adjacent
devices.
1. Before unloading tubing from the pump head, first turn off the drive. Open the pump head
by moving the actuator lever counterclockwise (left), as described above. This will
automatically open the tubing retainers, as well as lift the occlusion bed away from the
tubing. Pull the tubing away from the pump head
NOTE: When pump is not being used, store with actuator lever half way between far left and far
right positions (see Figures 5 and 6).
