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. 20 lbs of torque is recommended. The LGA-3
lead gasket should be replaced once each year, but only after the pressure manifold has
been properly evacuated.
- The VR2K is equipped with a drip leg and heater, which is designed to trap any solids
entering the unit and also to trap any chlorine that might have re-liquefied inside the
pressure manifold. The drip leg heater should be hot prior to operating the system.
- Pressure manifolds must include an adequate number of heated drip legs to trap the liquid
chlorine discharged from each ton container during initial use. It is also recommended that
the pressure manifold be constructed so that the line entering the VR2K is higher than the
rest of the pressure manifold, so as to prevent the possibility of excessive liquid chlorine
entering the VR2K vacuum regulator body.
1) Wall-mounting: After selecting the best location, mount the VR2K to the wall using the
wall-mounting hardware provided, connecting onto the VR2K as shown in Figure 1. The
VR2K must be installed vertically (as shown) with the drip leg down.
2) Gas inlet: The gas inlet connection on the VR2K is a 2-bolt 3/4" NPT union, which is
sealed with one lead gasket. Using proper PTFE thread treatment, connect the gas manifold
to the Archer union and using one LGA-3 lead gasket (included), bolt the union together. 20
ft/lbs of torque is recommended. Do not overtighten.
3) Vacuum: The VR2K vacuum connection is a 1" sch. 80 PVC union. Archer recommends all
vacuum lines be sch. 80 PVC 1" pipe.
4) Vent: All Archer vacuum regulators are equipped with a vent tubing connection for
directing and venting chlorine gas to a safe location. Tubing (1/2" O.D.) is also provided.
5) Heater: Prior to startup of the system or prior to placing any new ton container on
suction, the drip leg heater(s) must be powered for at least 15 minutes. This will ensure
any trapped chlorine liquid is evaporated before reaching the VR2K inlet valve. The heater
must always be powered during operation.
6) Refer to Figure 2 for proper gas feed system configurations.
