Precisionâ Instruction ManualOPERATION (Contd.)For Model 180, place the stainless steel metal tray (corners turned downward) inside the bath chamber. The tray pro-vides a sample base and protects samples from touching the hot metal bath bottom. Fill bath with distilled water towithin 3/4" of top of bath, allowing for displacement by sample(s) to be immersed, and for expansion of the media uponreaching operating temperature.NOTE:To conserve energy and to reduce evaporation, use a coverthroughout the temperature range of the bath. Do not use aluminumfoil as a cover; it may cause corrosion to the stainless steel as a resultof an electrolytic reaction.Each bath is supplied with a thermometer holder (metal clip) fastened to the top of the bath and a thermometer and O-ring packed separately. Slip O-ring onto thermometer, then insert thermometer through metal clip until line indicatingimmersion depth is at or below the water surface. When the shelf is in its highest position, the immersion line may beabove the water line; however, the thermometer bulb should be located above the diffuser pan.CAUTION: Care should be taken to protect the thermometer fromaccidental breakage and spillage of hazardous mercury content.Insert line cord into the proper receptacle and turn line switch to the "On" position. This action will energize the heaterand cause the red pilot lamp to turn "On" and stay lit while the heater(s) is energized. Set thermostat dial, as explainedbelow, to obtain the desired temperature setting.CAUTION: Exercise care when using acidic or caustic solutions,as they will attack the stainless steel bath body if spillage into thebath should occur.Clean and remove any spillage and condensation from all sheetmetal surfaces after each test. If spillage into the bath mediumhas occurred, the liquid should be drained and the unit thor-oughly flushed.-4-
