Flush the water seal trap
Flush the water trap of the polymer delivery pump 1 time per week. Flushing
removes diluted polymer that may have passed through the water trap seals. Some air
bubbles in the water trap are acceptable and do not affect performance. Leave the trap
filled with either distilled or deionized water.
1.
Fill the 20-mL syringe from the Polymer Block Cleaning Kit (Cat. No. 4335860)
with distilled or deionized water. Expel any bubbles from the syringe.
Note:
Do not use a syringe smaller than 20 mL. A smaller syringe may generate
excessive pressure within the trap.
2.
Attach the syringe to the forward-facing Luer fitting at the top of the pump
block. Hold the fitting with one hand while threading the syringe onto the fitting
with the other hand.
3.
Open the Luer fitting by grasping the body of the fitting and turning it and the
attached syringe approximately one-half turn counterclockwise.
4.
Open the exit fitting at the top left side of the pump block by turning it
approximately one-half turn counterclockwise.
