Replacement of the Drain Pump Tubing
The drain peristaltic pump tubing may need to be replaced due to wear
or damage. If liquid is not being drained from the glassware, first adjust
the tension on the peristaltic pump tubing. If any adjustment does not
solve the drainage problem, then the tubing should be replaced.
To replace the drain pump tubing, perform the following steps:
1 Turn the AC power switch to off (0) and disconnect the AC
power cord.
2 Remove the 1/16 inch O.D. PFA Teflon® tubing (3 lines) from the
top inlet side of the drain pump. Then remove the 3 longer lines
of FEP-lined Tygon® tubing from the outlet side of the pump.
3 Release the tension screws for all three channels of the drain
pump.
4 Carefully pull out the connector fittings from the drain pump
tubing holder.
5 Remove the tubing from the fittings and replace with new
tubing.
6 Reattach the drain tubing with the connector fittings to the
drain pump tubing holder (inlet and outlet).
7 Reconnect the 1/16 inch O.D. PFA Teflon® tubing (3 lines) to the
top inlet side, and the longer tubing to the outlet side (3 lines) of
the drain pump.
8 Secure the tension screws for all three channels of the drain
pump.
9 Adjust the tension screws as needed for a steady flow of drain
liquid.
