TANDEM Pump Tube Installation
Open the TANDEM pump head by moving the black loading lever 180
°
to the left. If using the upper
pump channel, slip the tubing into the upper channel; this is over the pump roller cage. If the lower
pump channel is used, feed the tubing through the lower channel; this is under the pump roller cage.
Do NOT mount or dismount the pump tubing while the ChemTec II is running.
NOTE: When using both upper and lower pump channels simultaneously, the same type of tubing
should be used in each channel.
Lock the tubing in place by pushing the loading lever 180
°
to the right. The tube retainer spring will
automatically place the correct tension on the pump tubing to prevent tube “walking”.
With the TANDEM pump head closed, lightly pull the two ends of the tubing in opposite directions and
away from the pump head. This pulling action insures that the pump tubing is taut and within the
pump channel.
TANDEM Pump Tube Replacement
The pump tubing section located in the TANDEM pump head should be advanced at regular time
intervals if the ChemTec II is heavily used. Only use high-quality Parker or Masterflex
™
pump tubing.
NOTE: When advancing pump tubing, the used pump tube section must be moved to the pump
discharge side, i.e. dispensing side. The used pump tube section is weakened and tends to collapse
when placed on the suction side of TANDEM pump head.
