Model VR3 Vacuum Regulator

General:

The Archer Instruments Model VR3 vacuum regulator is designed for use in

vacuum gas feed systems. The VR3 incorporates an integral graduated meter tube, which

provides a local indication of gas flow rate. The VR3 can be provided with or without an

integral rate control valve. *Note: For systems using an automatic switchover module, the

VR3 vacuum regulator should be plugged (rate valve removed) as the integral rate valve

can cause improper switchover operation.

Safety:

When working with chlorine, always use caution and follow applicable safety

procedures. General safety considerations:

* Store chlorine separately from ammonia.

* When using chlorine, avoid locations that expose the cylinder and equipment to direct

sunlight.

* Do not apply heater or heat source directly to chlorine cylinders.

* 150lb (upright) cylinders: Always keep cylinders upright and ensure the steel valve cap is

in place when moving cylinders. Once cylinder is in place, a safety chain should be used to

secure the cylinder.

* Ton Containers: Use appropriate handling equipment when moving ton containers. When

readying ton container for use, ensure valves are aligned vertically. The top valve accesses

gaseous chlorine and the bottom valve accesses liquid chlorine. The bottom valve should

never be touched unless your system employs a chlorine heat exchanger (evaporator)

designed expressly for use with liquid chlorine. When drawing gas from ton containers an

appropriate ton container adapter & drip leg must be used (also available from Archer

Instruments).
