MAINTENANCE

Hydrocollator® Heating Units

The Hydrocollator Heating Unit is equipped with an immersion type heating element and a hydraulic capillarytype thermostat which evenly maintains the HotPac temperature in the water and provides a ready supply of heated packs. It is critical to maintain the water level over the top of the HotPac to avoid damage to the heating element, the stainless steel, or the HotPac. Water is constantly lost during operation due to evaporation. Therefore, it is essential that water be added daily. The tank should also be drained and cleaned systematically, at minimum intervals of every two weeks. Always unplug the unit from the power source when emptying or cleaning the unit. Drain the unit by the drain valve located at the bottom rear of the unit. Either move the unit to a floor drain or attach the extension hose to it when draining. (E-1 units have no drain and can be emptied by turning unit upside down.)

WARNING • Chattanooga Group does not recommend the Hydrocollator Heating Unit be moved while filled with heated water. Tipping over could result in a burn to the user or others. If the Hydrocollator must be moved while filled, exercise extreme caution! It is recommended to allow the water to cool below 120° F (49° C) before moving the unit. • Always unplug the Hydrocollator Heating Unit from the power source before attempting to empty water from unit.

The Hydrocollator Heating Unit is made of high quality stainless steel that, with proper care and maintenance, could easily last a lifetime. Improper care could allow the stainless steel to wear prematurely. Follow these simple steps to ensure that the Hydrocollator Heating Unit remains in excellent condition. 1. Excessive chlorine can be detrimental to the stainless steel in the Hydrocollator Heating Unit . No bleach or any cleaner with high chlorine content should be used under any circumstance. 2. Clean regularly for optimal service and operation. NOTE: Failure to maintain the unit (including regular cleaning) will void the warranty. 3. Fill daily with water. Water is constantly lost during operation due to evaporation. 4. Chlorine in regular tap water may be present in high enough concentrations to damage the unit. If you suspect high levels of chlorine are detected in the Hydrocollator Heating Unit, the addition of a dechlorinator is recommended. 5. Certain additives (such as herbal teas, essential oils, etc.) will damage the HotPacs and components of the heating unit, including the stainless steel. The Hydrocollator Heating Unit was designed to heat water and HotPacs only. The addition of any such foreign substance (except dechlorinator) to the water in the unit will void the warranty. 6. Inspect heating element for pitting and other visible damage during regular cleaning intervals. 7. Inspect power cord for wear, fraying, and other visible damage during regular cleaning intervals.
