Installation Note for Solvent

Selection Valve Upgrade Kit

(G1360A)

This note describes how to install the solvent selection valve upgrade kit into

an Agilent 1100 Series binary pump.

General Information

The programmable solvent selection valve combines two out of four solvents

for binary pump formation or selects a different solvent for flushing the

column. It cannot be used as an gradient valve. When installed the solvent

selection valve can be activated from the set-up screens of your user

interface. For channel A you can select between A1 and A2, for channel B you

can select between B1 and B2. Position 1 is the upper connection of the

valve, whereas position 2 is lower position of the valve. The valve outlet is the

middle position of the solvent selection valve.

delivery checklist is shown in Table 1. Please report missing or damaged

parts to your local Agilent Technologies sales and service office.

Safety Information

WARNING The following procedures require opening the main cover of the binary

pump. Always make sure the binary pump is disconnected from the line

power when the main cover is removed. The security lever at the

power input socket prevents that the pump cover is taken off when

line power is still connected.

WARNING To disconnect the binary pump from line, unplug the power cord. The

power supply still uses some power, even if the switch on the front

panel is turned off.

WARNING When opening capillary or tube fittings solvents may leak out. Please

observe appropriate safety procedures (for example, goggles, safety

gloves and protective clothing) as described in the material handling

and safety data sheet supplied by the solvent vendor, especially when

toxic or hazardous solvents are used.

NOTE The electronics of the binary pump will not allow operation when the top

cover and the top foam are removed. A safety light switch on the main board

will inhibit the operation of the binary pump. Always operate the binary pump

with the top foam and top covers in place.

CAUTION Internal components may be sensitive to electrostatic discharge (ESD).

Always use an ESD kit (shipped with the standard accessory kit of your pump)

when handling internal parts.

Upgrade Kit

The following procedure concentrates mainly on installation of new parts

and gives only basic information about preparation steps, such as top cover

removal, and so on. Refer to your Reference Manual in section “Repairing

Your Pump” for detailed descriptions of these procedures.

Tools required

Screwdriver Pozidriv #1

Wrench 1/4 inch

Wrench 14 mm

Wrench 7 mm

Wrench 5 mm

Before beginning this procedure:

❏Switch off binary pump at the main power switch.

❏Disconnect the solvent inlet tube and the adapter at the active inlet valve.

Beware of leaking solvents due to hydrostatic flow.

❏Remove the solvent cabinet from the binary pump.

1Remove front cover, top cover, metal plate

and top foam section. Remove the cover plate

that covers the position of the solvent

selection valve.

2Disconnect capillaries, tubes and connectors

from the two pump heads and the damper.

Remove the mixing chamber from its holder.

3Disconnect the connectors of the active inlet

valve and the damper from the main board

(J19, J24, J28), loosen the Z-panel screws and

take out the damper. Remove the Z-panel.

4Disconnect both pumps from the main board

(J16, J17, J12, J27) and lift them out of the

foam.

5Remove the HPM board, for help see

“Exchanging the HPM Board”in your

Reference Manual.

6Push the leak sensor cable through the

bottom of the foam and lift the foam out.

7Push the connector plate of the SSV cable

assembly into the slit of the bottom foam.

8Place the cable in the slit of the lower side of

the foam and lead it through the hole in the

foam.

9Slide the leak sensor cable through the

bottom foam (underneath the newly installed

SSV connector plate). Replace the bottom

foam and fix the leak sensor cable in the

foam.

10 Reinstall the main board and reconnect all

cables. The SSV cable will be connected to

J30 on the board.

11 Slide the SSV block with the two selection

valve into its position and fix with the two

screws.

12 Replace the two pump units and connect to

the main board (J16, J 17, J12, J27).

13 Place Z-panel into its position and replace the

damper. Fix the Z-panel and reconnect the

cables at the main board (J19, J28, J24).

14 Reconnect all capillaries, tubes and cables to

the pump heads and the damper. Fix the

mixing chamber in its holder.

Installing the Solvent Selection Valve Upgrade Kit

15 Connect the two connecting tubes between

the middle positions of the SSV’s and the

active inlet valve.

16 Replace top foam, metal plate and top cover.

Reinstall the leak funnel with the waste tube

and re-locate the waste tube in the holder in

the leak pan.

On completion of this procedure:

1Place the binary pump back to its position in

the stack, replace the solvent cabinet. Add the

two additional bottles with the bottle head

assemblies to the cabinet and connect the

tubes to the solvent selection valve.

2Connect the power cables to the pump and

turn on the instrument.
