WARNING!
Always wear safety goggles when working with refrigerant. Use only autho-
rized refillable refrigerant tanks. Disconnect hoses with extreme caution!
All hoses may contain refrigerant under pressure. Read and follow all
warnings at the beginning of this manual before operating the unit.

system and that the high and low side valves are open.
