Floor Stand Reactors PREFACE Safety Information Scope To avoid electrical shock, always: 1. Use a properly grounded electrical outlet of correct voltage and current handling capability. 2. Ensure that the equipment is connected to electrical service according to local national electrical codes. Failure to properly connect may create a fire or shock hazard. 3. For continued protection against possible hazard, replace fuses with same type and rating of fuse. 4.

If present on the product, the user must consult the appropriate part of the accompanying product literature for more information. This CAUTION symbol indicates that the surface may be hot. Protective Earth (PE) terminal.
Floor Stand Reactors User’s Responsibility All Parr Reactors and pressure vessels are designed and manufactured with great care to assure safe operation when used within their prescribed temperature and pressure limits. But . . . the basic responsibility for safety when using this equipment rests entirely with the user; who must: 1. Select a reactor or pressure vessel which has the capability, pressure rating, corrosion resistance and design features that are suitable for its intended use.
Floor Stand Reactors INSTALLATION Pressure and Temperature Limits The working pressure and temperature at which any reactor or pressure vessel can be used will depend upon the design of the vessel and the materials used in its construction. Since all materials lose strength at elevated temperatures, any pressure rating must be stated in terms of the temperature at which it applies. The standard material of construction for Parr Instrument Company is Type 316 Stainless Steel.
Floor Stand Reactors This knob is attached to the upper drive shaft and the universal coupling. Lifting the knob will allow the alignment of the universal coupling and the drive adapter attached to the magnetic drive. Turn the knob to align the slot in the drive adapter with the universal coupling. Parr Heating Only: The Parr Heating output connector is to be used only with Parr Instrument Company heater assemblies supplied with the appropriate heater power cord.
Floor Stand Reactors IDENTIFY THE VALVES Gas Inlet Valve The gas inlet valve is easily identified when the bomb is open by noting that it is connected to a dip tube that extends to a point near the bottom of the bomb cylinder. This is an angle valve with an attached fitting which provides a socket for attaching the A495HC pressure hose furnished with the reactor. Gas Release Valve The gas release valve is connected to an opening that will not have any fitting installed on the underside of the head.
Floor Stand Reactors OTHER VESSEL HEAD FITTINGS Safety Rupture Disc There is a safety rupture disc attached to the head that is intended to rupture and release the pressure before it reaches a dangerous level. A metal tag wired to the safety head identifies the burst pressure at room temperature for that particular disc. A similar tag is furnished with each replacement disc. This tag must remain with the apparatus at all times so that both present and future operators will be aware of the disc rating.
Floor Stand Reactors HOW TO USE THE VESSEL Fixed Head Vessels First, lower the heater and push it aside before attempting to remove the split ring and cylinder. Raise the cylinder support holder to the bottom of the cylinder. Open the gas release valve to discharge any internal pressure. To open the Vessel Remove the split rings. For vessels with a confined, flat PTFE gasket, loosen the six bolts. For vessels with an O-ring closure, loosen the latches on each side of the split rings.
Floor Stand Reactors be used at ambient temperature for all non-corrosive gases at pressures up to 2500 psig. For operations involving corrosive gases, this hose should be replaced with an A490HC hose which has a PTFE lining and a braided stainless steel outer covering. Both of these hoses have the same fittings. The A506HC all metal hose is also available in stainless steel and other corrosion resistant materials.
Floor Stand Reactors ACCESSORIES Internal Cooling Coils Cooling coils can be installed in any of these reactors. Reactors purchased without a coil can have this feature added. Standard cooling coils are made in serpentine configurations. A serpentine coil offers a smaller but effective cooling area and it does not interfere with the use of a liner.
Floor Stand Reactors EXPLOSION PROOF OPERATION If the local safety code requires that equipment installed in the user’s laboratory must be explosion proof, there are four possible ignition hazards to be considered: 1. The Motor The standard adjustable speed motor is not explosion proof, yet these motors are not unduly hazardous if operated in a well ventilated location where care is taken to prevent the accumulation of explosive gases or vapors.
Floor Stand Reactors GENERAL MAINTENANCE NOTES 1. Periodically inspect all electrical wiring and pressure connections for excessive corrosion. Suspect parts should be replaced by components only supplied by Parr Instrument Company. 2. Always use appropriate wrenches on all fittings and valves. Never use pliers or pipe wrenches. 3. Head and cylinder service fixtures are available for convenience and protection of components during maintenance of your reactor. 4.
