2.7   Install Valve Pump Assembly

The pump assembly has a vacuum pressure system that:

l

Eliminates internal pump tubing

l

Uses significantly less reagent

l

Accurately moves fluids through the analyzer. 

Perform the following procedure to install valve pump assembly:

1.  Tilt pump assembly towards you.
2.  Align the hinge pins and sockets, and slide assembly tray as far as possible to right (see Figure 2­7).   

Carefully lay tray down into cabinet

3.  Plug in the two connectors to the back of the cabinet (6­position connector for heating bath; 9­position

connector for pump) (see Figure 2­8).

4.  Connect 16­pin connector from pump assembly to small connector on CPU board (yellow ejector) above

connector for keypad panel.

5.   Attach colorimeter inlet tubing on left side of pump to flowcell inlet (see Figure 2­1).
6.   Continue with procedure depending on whether system is single­stream or multi­stream.

6.  Thread tube labeled  Sample" through hole  0n bottom of shelf to the right of pump assembly, and out 

through hole on left side of cabinet.

7.   Connect Sample tube to top of overflow sample on left side of cabinet.
8.   Guide all other   tubes that are attached to valve pump assembly through reagent cabinet access hole. 

6.  Thread Sample tube from pump assembly through reagent access hole on the right side of the valve    

pump assembly, and connect to Common (C) on #1 multi­stream solenoid valve on left side of reagent   

cabinet.

Guide all other tubes that are attached to valve pump assembly through reagent cabinet access hole.
