Exchanging the Purge Valve Frit or the

 

Purge Valve

 

 

When required

Frit – when plunger seals are exchanged or when contaminated or blocked (pressure drop of

 

> 10 bar across the frit at a flow rate of 5 ml/min of H20 with purge valve opened)

 

Purge valve – if internally leaking

Tools required

Wrench 1/4 inch

 

Wrench 14 mm

 

Pair of tweezers or toothpick

Parts required

PFTE frit (pack of 5) 01018-22707

 

Purge valve G1311-60009

 

 

1Using a 1/4 inch wrench disconnect the pump outlet capillary at the purge valve.

2Disconnect the waste tube. Beware of leaking solvents due to hydrostatic pressure.

3Using the 14 mm wrench unscrew the purge valve and remove it.

4Remove the plastic cap with the gold seal from the purge valve.

5Using a pair of tweezers or a toothpick remove the frit
