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).
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. Continue with procedure depending on whether system is singlestream or multistream.
For singlestream, continue:
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.
8. Guide all other tubes that are attached to valve pump assembly through reagent cabinet access hole.
For multistream, continue:
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.
