Install Buffer Tubing
Apply plenty of buffer grease (included with the new buffer pump tubing) to the new buffer pump tubing. Only apply the
grease to the large diameter section of the tubing. Do not apply calibrator pump grease to the buffer pump tubing.
Insert the new pump tubing around the pump roller assembly and into the buffer pump. Make sure the small white fitting
with the small diameter tubing is on the left side of the pump.
Place the blue pump head cover onto the buffer pump and press until it snaps into place.
Connect Buffer Tubing
Connect the small diameter tubing from the Buffer Pump to the rear tube of the sipper pump.
8.4.6.2 Calibrator Pump Tubing
Apply plenty of calibrator grease (included with the new calibrator pump tubing) to the larger diameter section of new
calibrator pump tubing. Do not apply this calibrator pump grease to the buffer pump tubing.
Insert the new pump tubing around the pump roller assembly and into the calibrator pump. Make sure the short section of
tubing is on the left side of the pump. The tubing attached to this fitting connects to the fitting on the waste module.
