SAFETY PRECAUTIONS
! Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can cause
frostbite.
! Follow the RR750X operating procedures sequentially to avoid prematurely disconnecting hoses
or opening valves which may release refrigerant to the atmosphere.
! Do not expose the RR750X to moisture or operate in wet areas.
! Use the RR750X in locations with mechanical ventilation that provides at least four air changes
per hour or locate the unit 18 inches above the floor.
! Service hoses used with the RR750X must have shutoff devices within 12 inches of the
connection point to the system being serviced to minimize the introduction of non-condensable
gases into the recovery unit and the release of refrigerant when being disconnected.
! Disconnect power before performing any maintenance or service on the RR750X.
! Avoid using an extension cord with the RR750X. If necessary, use a good condition, UL listed,
3-wire grounded, #14 AWG extension cord of the shortest possible length.
! Do not introduce refrigerant in the liquid state into the RR750X from any source having greater
than a 4.5 lb. capacity. Steady introduction of large amounts of liquid refrigerant may cause the
RR750X to malfunction.
! Connect RR750X to grounded and protected 115 VAC - 60 HZ power source.
! Recover R-12 refrigerant only.
