1. SAFETY PRECAUTIONS Warning & Cautions Warning Never operate equipment near combustible gases/fumes. Do not install or operate SM series unit near flammable or explosive gases/fumes. Unit is NOT fire or blast resistant. Negligent use could cause a fire/explosion. See “List of Hazardous Substances” (P.40). - Page 7 1. SAFETY PRECAUTIONS Warning & Cautions Equipment under pressure. DO NOT open unit lid until pressure gauge reads “0” (zero) psi. Opening while pressurized will allow high temperature, high pressure steam to abruptly escape chamber, possibly causing serious burns or other personal injury. When opening unit, always confirm pressure gauge reads “0”...

2. PRE-OPERATION PROCEDURES Installation Precautions 1. Opening lid. OPEN Before opening unit lid, be sure that the pressure gauge reads “0 psi". Then, proceed to open slowly. If lid is opened while unit is still under pressure, hot steam will abruptly escape chamber, possibly resulting in burns or other serious personal injury, caused by sudden reflexive movements. - Page 16 2. PRE-OPERATION PROCEDURES Installation Precautions 4. Caution: HOT! During and following operation, areas surrounding the lid become very hot. Do not touch these areas. ◆ Areas in gray signify HOT surfaces, in illustration to the right. 5. Chamber lid seal.
