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

	WA R N I N G	The normal surface temperature of the pump body at ultimate vacuum (operation) at
	WA R N I N G	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.

	WA R N I N G	Do not operate the vacuum pump with the oil level below the minimum oil level mark or
	WA R N I N G	above the maximum oil level mark.
		above the maximum oil level mark.

1Install 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).

2Remove the protective cap from the pump inlet port.

3Install the metal conical screen and black centering o-ring into the pump inlet port (see Figure 13).

4Attach the aluminum 1/2-inch barbed adapter to the pump inlet port with the metal clamping ring.

5Slide the 2 inches Tygon vacuum hose over the pump inlet barbed adapter and secure with a hose clamp.

6Slide another hose clamp over the 2 inches Tygon vacuum hose.

7Remove the plastic caps from the barb fittings on the ends of the chemical trap.

8Press the trap into the mounting bracket and the 2 inches of Tygon vacuum hose (see Figure 11 and Figure 12).

9Tighten the hose clamp.

10Locate the Oil Return Line Kit.
