Read these instructions carefully and completely before using equipment.

Keep for reference. 

We could not possibly know of and advise the service trade of all conceivable procedures by which a service might be performed and of the possible hazards and/or results of each method. We have not undertaken any such wide evaluation. Therefore, anyone who uses a service procedure and/or tool, which is not recommended by the manufacturer, first must completely satisfy themselves that neither they, the product's safety, nor the area in which the work is being performed, will be endangered by the service procedure selected.

DO NOT OPERATE THIS EQUIPMENT UNLESS THE USER IS FULLY TRAINED IN THE SAFE USE OF PRESSURE REDUCING REGULATORS AND THEIR RELATED COMPONENTS. 

The safe and effective use of this equipment depends on the Technician fully understanding and carefully following practical time-tested safety and operating instructions to prevent and avoid unnecessary painful injuries and costly property damages and losses due to improper equipment use. Use the regulator only for the gas or gases and service for which it is intended. It is against the manufacturer's warranty and liability-promises to use or sell CO₂ regulators for dispensing of beer. For purging and pressure testing always use a pressure reducing regulator. 

USE PROPER EYE PROTECTION. 

NOTE: Per OSHA standards (29CFR 1910.252) a pressure reducing regulator shall be used with all compressed gas cylinders. 

Proper "head-to-toe" protection includes hair and head coverage, safety tempered lens eye goggles (shade 5 minimum), body coverage including gloves and shoes. Avoid wearing anything flammable or clothing that has been exposed to flammables (oil, grease, solvents, etc.). Sparks and molten materials have a way of finding the unprotected areas, so be properly prepared before starting work. 

Adequate ventilation must be provided, especially in confined work areas to remove harmful fumes and provide an adequate air supply for the user and the equipment. For safety sake double check all the equipment for leaks BEFORE entering a confined work area. Any leak in a confined space can cause serious problems. 

Important: Pure oxygen will rapidly increase burning of almost any ignited material especially oil and grease and must never be allowed to saturate a confined work area. Oxy-Fuel/Vapor or Air-Fuel/Vapor concentrations in confined unventilated areas can also be hazardous and explosive if ignited. 

DO NOT use a torch on containers or pipes unless they are properly cleaned, purged, and vented or if vapor gas fumes are present. Flammable gases and vapors can explode if ignited by using a torch on a container or pipe line. Fuel gases have an odor; if the user smells gas DO NOT use the equipment until the source of the leak is located and stopped, and until the surrounding area is properly ventilated and safe to continue work. 

Some solvents and chemicals may become toxic and hazardous when heated - 
DO NOT inhale fumes.

Never use a regulator to pressurize any tank, drum, or container above its manufacturer's recommended pressures. Be aware that regulator pressure relief devices are designed to protect the regulator only. Downstream equipment should be protected with its own pressure relief device of proper size and capacity. 

Fire protection must be provided for the work area. The user must be fully aware of the impact of the torch flame, sparks, and molten materials on both the immediate work area and surroundings including hoses and other equipment. 

 Sparks can fly over 35 feet. 

Remove all flammables where possible and carefully cover or shield anything that can possibly catch fire or explode (or both) with fireproof materials. Carefully check out the area after work is completed for places where sparks or molten material could light and smolder. Always have the proper fire fighting equipment available for immediate use. It is a good idea to have a bucket of water available in the work area at all times. A water bucket is also handy for leak testing torches and hoses, cooling work, or catching molten metal and slag. 

A fire watch is recommended for at least one hour after work is completed.

Keep hoses and everything that can burn or explode clear of sparks and hot metal. 

Keep cylinders clear of flames, electric arcs, and other dangerous situations.

DO NOT store cylinders and equipment in unventilated confined spaces, closed vehicles or trunks, rooms used for habitation or near any source of heat or ignition. Gas leaks can cause a fire or explosion when ignited. 

To ADJUST the REGULATOR turn the PRESSURE ADJUSTING SCREW CLOCKWISE (to the right) to INCREASE the pressure and COUNTER-CLOCKWISE (to the left) to DECREASE the pressure and turn OFF the regulator. 

DO NOT try to exceed the maximum pressure psig rating of the regulator or the gauges. The gauge mechanisms can be damaged. 

DO NOT use acetylene over 15 psig. 

Turn the regulator adjusting screw clockwise (to the right) for the proper delivery pressure. 

EXAMPLE: 125 psig rated delivery pressure regulator uses a 200 psig gauge and a 4000 psig gauge for 3000 psig maximum inlet rating at 125ºF. This provides a safety factor for the pressure gauge. 

AT NO TIME should the user exceed the manufacturer's recommended pressure setting or the WORKING pressure of the hose. 

The regulator pressure relief device is designed to protect the regulator outlet pressure gauge - NOT DOWNSTREAM SYSTEMS. 

All systems must have a proper capacity pressure relief device or other suitable means of excess pressure protection included downstream of the regulator when pressurizing a closed container or any system which requires excess pressure protection to avoid personal injury and equipment damage. 

Regulator plastic parts such as gauge lenses and flowmeter tubes or rubber parts like diaphragms and O-rings should avoid contact with solvents. Solvents can damage these parts. 

Flowgauge regulators must have the same outlet orifice size as printed on the gauge dial and Uniweld flowmeter regulators must be preset to 50 psig to operate properly. All flowmeters must have a properly set pressure reducing regulator between the cylinder and flowmeter. 

DO NOT USE THE EQUIPMENT UNTIL ALL CONNECTIONS AND EQUIPMENT ARE LEAK FREE.

Properly pressurize the system. To check for leaks close the cylinder valve and turn the pressure adjusting screw one turn counter-clockwise (to the left). If the high pressure gauge reading drops, there can be a leak in the cylinder valve connection or high pressure gauge connection. If the low pressure gauge drops, there can be a leak in the equipment valves, hose connections, hose, low pressure gauge connection, or check for diaphragm leak at the bonnet vent hole. Check for leaks using proper leak testing solution. If the high pressure gauge drops and at the same time the low pressure gauge rises, there is a leak in the regulator seat.

DO NOT USE THE EQUIPMENT UNTIL THERE ARE NO LEAKS IN THE SYSTEM.

 The regulator must be repaired by Uniweld or a Uniweld Authorized repair station, using Uniweld parts. Special technical training is required to service or repair cutting, welding, and ancillary equipment.

NOTE: Per OSHA standards (29CFR 1910.252) only properly instructed skilled personnel shall perform repairs on regulators.
