This manual describes how to install, operate, and troubleshoot the Agilent G6011B Quiet
Cover MS for LC/MS rough pumps.
Your rough pump fits in the Quiet Cover MS to significantly reduce noise, while an internal fan
ensures that your pump will not overheat. There is an easy-to-use kickstand and a full-size oil tray
to facilitate changing the oil. There are also multiple access panels for easy access to the pump
for routine maintenance.
The Quiet Cover MS is only compatible with the Agilent MS40+ and MS40S Rotary-Vane Pump
used with electron microscopy and mass spectrometry including the LC/MS.

3Install the rough pump into the Quiet Cover MS. Orient the rough pump support foot into the
front mounting cup inside the Quiet Cover MS and between the Quiet Cover MS mounting tabs
so that the pump oil level window sight glass faces the front access door (Figure 7).
•The rough pump should fit against the Quiet Cover MS motor air duct when the pump feet are
positioned between the mounting tabs and inside the one mounting cup. A slight gap is
acceptable. If the support feet do not align with the mounting cup and mounting tabs, the
rough pump orientation is incorrect.
•Pump should be slightly touching both the motor air duct and the electrical panel access door.
4Connect the pump power cord to the rough pump through the EBox opening (Figure 8).
5Set the power switch to the On position through the EBox opening (Figure 8 on page 17).
NOTE
The pump is controlled by the MS and should always be left on.
6Install the clear PVC exhaust hose included with the quiet cover to the MS40 exhaust port.

2Lock the casters to avoid unwanted movement of the Quiet Cover MS.
3Turn the Power Switch to the off position.
4Plug the G6011B Quiet Cover into an external power outlet. If the instrument is receiving
power, the Power Switch (Figure 1) should light up orange.
5Turn the Power Switch on. If the instrument is turned on correctly, the Power Switch (Figure 1)
should light up green.
If the ambient temperature is < 35 °C, the temperature alarm and the fan should be off, and
the status indicator should light up green.
If the Quiet Cover internal temperature exceeds 35 °C, the fan should turn on, and the status
light will light up orange. This is the normal operating mode.
NOTE
In normal operating modes, the status light will be either green or orange, depending on if the fan
is on or not.
