Every degreaser is provided with specific operating instructions for safe, economical, and efficient operation of the unit. Since these instructions vary with design, type, and work cycle of the unit, it is essential that the operator be familiar with specific instructions pertaining to his unit. Operating instructions should be posted in a conspicuous place on the degreaser. All degreasers are designed to process a maximum load rated in pounds per hour based on a specific heat input to vaporize sufficient solvent. If the work capacity of the unit is exceeded, vapor level fluctuations will be encountered. These fluctuations increase solvent consumption and may also cause poor cleaning and longer cleaning cycles.
