Step 3. Install the Rough Pumps inside Mass Spec Bench
The rough pump(s) must be oriented correctly when installed. The rough
pumps have either multiple cooling fans or a single fan. If the pump contains
oil, the sight glass (used to check the oil level in the pump) must face the door.
Otherwise, oil level in the pump will be difficult to determine. If the pump is
an oil-free design (dry pump), the main cooling fan must face the rear of the
Mass Spec Bench

1 Unpack and prepare the rough pumps as described in the LC/MS or GC/MS
System installation manual.
Preparation includes the installation of the oil mist filters (Edwards
pumps) and exhaust adaptors (Edwards and Agilent pumps).
2 Put the rough pumps on the metal oil drip tray (part number G1946-00064)
while the pumps are on the floor.

For this step, the castors must extend to keep the Mass Spec Bench in place. Otherwise,
the Mass Spec Bench can move around while the pumps are being installed.
