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.

3 Install 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).
Figure 7. Mounting cup and mounting tabs on the Quiet Cover MS
• 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.
4 Connect the pump power cord to the rough pump through the EBox opening (Figure 8).

5 Set the power switch to the On position through the EBox opening (Figure 8 on page 17).
The pump is controlled by the MS and should always be left on.

Verifying the Installation
When the G6011B Quiet Cover is plugged into an external power outlet, the Power Switch (front
lower left-hand corner of the Quiet Cover) will light up orange. This indicates that power is
connected to the Quiet Cover.
To verify that you installed the Quiet Cover MS correctly,
1 Position the power cords so they do not interfere with the kickstand (Figure 2).
2 Lock the casters to avoid unwanted movement of the Quiet Cover MS.
3 Turn the Power Switch to the off position.
4 Plug the G6011B Quiet Cover into an external power outlet. If the instrument is receiving
power, the Power Switch (Figure 1) should light up orange.
5 Turn 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.
In normal operating modes, the status light will be either green or orange, depending on if the fan
is on or not.

Handling Temperature Alarms
In normal operation the Quiet Cover MS fan will turn off and on to maintain the temperature set
limits. The status light will be green when the fan is off. The status light will be orange when the
fan is on, but the temperature is still within set limits. Both statuses are normal operating modes.
If the air flow to the Quiet Cover MS is restricted or if the room temperature is above 35 °C (95 °F),
the red status indicator on the front panel lights and the temperature alarm sounds.
When this condition occurs, remove any items from around the Quiet Cover MS that could be
restricting air flow. Check that the fan is turning and that air flow to the Quiet Cover MS is not
restricted.
It is important that the Quiet Cover MS not recirculate hot air. Always position the front end of
the Quiet Cover MS where it can draw cool air.
You cannot turn the alarm off. It will stop when the temperature returns to an acceptable level.

Periodically, you must change the rough pump oil. The oil tray of the Quiet Cover MS is designed
to collect the oil as it drains from the pump. Please refer to your pump documentation for detailed
information regarding changing your pump oil.
To change the oil:
1 Properly prepare your system for release of primary vacuum.
2 Turn off the rough pump.
3 Turn off the Quiet Cover MS.
4 Unplug the power supply from the Quiet Cover MS.
5 Lock the locking casters to secure the Quiet Cover MS.
6 Open the front access door of the Quiet Cover MS.
7 Tilt the Quiet Cover MS by using the kickstand located at the back of the Quiet Cover MS
(Using the Kickstand on page 24.) This technique is the most efficient way to drain the pump
oil.
8 Be sure the oil tray is securely seated.
The pump sits close to the front of the Quiet Cover MS.
Pull the tray out 1 to 2 inches to avoid oil spillage.
