Chapter 6: Installing the Valve/Pump Module
69
Install the 6-Port Valve
If the 6-port valve is not already installed on the valve/pump module, you need
to install it as described in this section. If the 6-port valve is already installed,
you may need to change its orientation (see “Replacing or Reorienting the 6-
Port Valve” on page 121).
It is important to minimize the length of the tubing between the valve/pump
module and the instrument's nebulizer.
You can place the valve/pump module so that the valve is toward the top, or
toward the bottom, as needed.
During operation, the valve/pump module must be placed on one of its ends. The
valve/pump module is not hermetically sealed. Placing it with the valve facing up
may result in the introduction of liquid into the electronics of the box.
1 Place the valve/pump module on its back.
2 Insert the valve at the desired angle. Rotate it so that the nebulizer port will be
as close as possible to the nebulizer.
3 Press down on the valve so that it is completely seated.
4 Inspect the valve to verify that there is no gap between the valve and the collar
on the valve/pump module.
