Installing the Model VR2K: *IMPORTANT SAFETY NOTES: - The VR2K inlet assembly is connected to the back of the vacuum regulator by means of a lead gasket seal (lead gasket part# LGA-3) and four (4) socket head cap screws. Prior to use and during any periods of significant change in ambient temperature, these screws should be checked to make sure they are tight.

NOTE: Vent tubing should always be connected and run to a safe location (outside of any building). A vent screen (provided with every Archer Instruments vacuum regulator) should be fitted over the end of vent tubing to prevent insects from entering.

VR2K, gas feed will begin when the ejector is put into operation. NOTE: If the gas supply to the VR2K is exhausted, the guide pin will retract into the front body. This indicates that gas is no longer flowing and that increased internal vacuum has caused the diaphragm to fully open the inlet valve.

9) When reassembling, new o-rings should be given a thin film of the Fluorolube grease. SAFETY NOTE: The inlet valve assembly is a critical component of the VR2K. Improper handling or reassembly can result in dangerous leakage of chlorine gas. Archer Instruments recommends that only trained personnel or those familiar with vacuum regulator maintenance service the VR2K.
