BEFORE USING THE RHS730
Check for any shipping damage. Place a claim with carrier if damage is discovered. DO NOT USE A DAMAGED UNIT.
These general instructions describe normal operation and maintenance situations encountered with the RHS730. Failure
to read and comply with these instructions or any one of the limitations noted herein can result in serious injury and/or
property damage.
A few minutes spent reading these instructions can make an operator aware of dangerous practices to avoid and
precautions to take for his own safety and the safety of others. The instructions should not be interpreted to anticipate every
possible contingency.
The RHS730 should not be operated or serviced by any person who has not read all the contents of this manual.
It is the responsibility of the owner/user to operate the RHS730 in accordance with all specifications and laws which may
apply.
A regular schedule of inspection of the RHS730 should be established and records maintained with special attention given
to Hoses, Vacuum Pump Oil Level and Filters.
SAFETY PRECAUTIONS
Recycle and Charge only the refrigerant for which the machine is configured.
Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can cause frostbite.
Follow the RHS730 operating procedures sequentially to avoid prematurely disconnecting hoses or opening valves which
may release refrigerant to the atmosphere.
Do not expose the RHS730 to moisture or operate in wet areas.
Use the RHS730 in locations with mechanical ventilation that provides at least four air changes per hour.
Hoses used with the RHS730 must have shutoff devices within 12 inches (30 centimeters) of the connection point to the
A/C System to minimize the introduction of Non-Condensable Gas (Air) into the RHS730 and the release of refrigerant
when being connected or disconnected.
Disconnect power before performing any maintenance or service on the RHS730.
Connect the RHS730 to a properly grounded receptacle. Do not over load the circuit (20 amp minimum).
Avoid using an extension cord with the RHS730. If necessary, use a good condition three wire, grounded, #14 AWG (2.0
mm
2 ) or larger extension cord of the shortest possible length (maximum 25 ft. - 8 m).
Do not connect the RHS730 to the liquid side of any A/C System with a capacity greater than 4 lbs (1.8 Kg.) Refrigerant
in A/C Systems having larger capacities must be recycled from the vapor side only.
Never connect the Red or Blue Hose of the RHS730 to the Liquid Port of a Cylinder of Refrigerant to fill the Charge
Cylinder. Doing so may cause the Compressor to fail and void the warranty.
Avoid breathing refrigerant or lubricant vapor or mist. Exposure may irritate eyes, nose and throat. If accidental system
discharge occurs, ventilate work area before continuing.
Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.
SPECIAL CONSIDERATIONS WITH R134a
R134a has been shown to be nonflammable at ambient temperature and atmospheric pressure. However, tests under
controlled conditions have indicated that at pressures above atmospheric and with air concentrations greater than 60
percent by volume, R134a can form combustible mixtures.
While it is recognized that an ignition source is also required for combustion to occur, the presence of combustible mixtures
is a potentially dangerous situation and should be avoided.
Under no circumstances should any equipment be pressure tested or leak tested with air and R134a mixtures. Do not use
compressed air (shop air) for leak detection in R134a systems.
