Step 3: Set Up the Vacuum Pump
Initial connections require access to the rear of the Detector and the vacuum
pump. Follow the installation instructions for either the RV5 Edwards pump
or the oil-free dry piston pump, depending on your configuration.
Installing the Edwards RV5 Pump Oil-Sealed Vacuum Pump
1 Install the chemical trap mounting bracket to the top of the pump with the
screws and provided wrench. The chemical trap is a white plastic cylinder
approximately 1 foot (30 cm) in length by 1.5 inches in (3.8 cm) diameter
fitted with a barbed fitting on both ends (see Figure 11).
2 Remove the protective cap from the pump inlet port.
3 Install the metal conical screen and black centering o-ring into the pump
inlet port (see Figure 13).
4 Attach the aluminum 1/2-inch barbed adapter to the pump inlet port with
the metal clamping ring.
5 Slide the 2 inches Tygon vacuum hose over the pump inlet barbed adapter
and secure with a hose clamp.
6 Slide another hose clamp over the 2 inches Tygon vacuum hose.
7 Remove the plastic caps from the barb fittings on the ends of the chemical
trap.
8 Press the trap into the mounting bracket and the 2 inches of Tygon vacuum
hose (see Figure 11 and Figure 12).
9 Tighten the hose clamp.
10 Locate the Oil Return Line Kit.
WARNING
Exhaust gases from the pump should be vented to a fume hood to eliminate any potential
hazard.
WARNING
The normal surface temperature of the pump body at ultimate vacuum (operation) at
ambient temperature of 20 °C is 50 °C to 70 °C. If you use the pump at a high ambient tem-
perature, the temperature of the pump body may exceed 70 °C, and you must fit suitable
guards to prevent contact with hot surfaces. For more information refer to the pump oper-
ating manual.
WARNING
Do not operate the vacuum pump with the oil level below the minimum oil level mark or
above the maximum oil level mark.
