  • Page 11: R134a Refrigerant Service Information

    R134a REFRIGERANT SERVICE INFORMATION This product uses R134a refrigerant. This refrigerant requires synthetic Ester Oil in the compressor. This cooling system does not tolerate contamination from any of the following: • Other Refrigerants • Moisture • Petroleum-based Lubricants • Silicone Lubricants •...
  • Page 12: Safety Precautions

    SAFETY PRECAUTIONS TREAT LIQUID AND VAPORIZED REFRIGERANT WITH RESPECT. IN CASE OF ACCIDENTAL RELEASE OF LARGE AMOUNTS OF REFRIGEANT: Vapors from the refrigerant can reduce the oxygen available for breathing and cause suffocation. Refrigerant decomposes rapidly and becomes toxic and corrosive when it reaches approximately 1100° F. Refrigerant can cause skin irritation and frostbite.
  • Page 13: Equipment And Tools

    EQUIPMENT AND TOOLS A separate set of hoses and hand valves must be maintained for use with sealed systems with R134a refrigerant. Equipment used with CFC refrigerants will contaminate R134a (HFC) sealed systems. EQUIPMENT DESCRIPTION ILLUSTRATION Tank of Liquid Refrigerant – Care should be taken to be sure the proper refrigerant is available.
  • Page 14 EQUIPMENT DESCRIPTION Purging Hose Configuration – This arrangement of three 4’ to 6’ hoses with low-loss fittings and a ¼” male flare Tee fitting can be used to purge a sealed system for both operating and non-operating compressor situations. No hand valves are required.
  • Page 15 EQUIPMENT DESCRIPTION Swaging Kit – A swaging tool kit may be needed to expand system tubing to fit replacement parts. (Fig. 19) Heat Gun – A heat gun can be used to heat a non-operating compressor or the evaporator during purge and the refrigerant tank to increase charging pressure. Many heat guns have a stand that allows continuous operation while other repairs are made.
  • Page 16 EQUIPMENT DESCRIPTION Inspection Mirror, Tubing Cutter, Triangular File and Steel Brush – The inspection mirror should be small enough to inspect in tight spaces around joints. A mini-cutter will be required to cut tubing in tight spaces where a standard cutter will not turn.
