MAINTENANCE
Care and Cleaning
The Hydrocollator is equipped with an immersion type heating element and a hydraulic capillary type
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.
Your Hydrocollator Heating Unit is made of high quality stainless steel that should last a lifetime. You must
properly care for your Hydrocollator Heating Unit if you wish for it to last a lifetime.
Follow these simple steps to ensure that your Hydrocollator Heating Unit lasts.
1. Chlorine means rust to stainless steel. No bleach or any cleaner with high chlorine content should be used.
2. Clean regularly for optimal service and operation.
NOTE: Failure to maintain your equipment (including regular cleaning) will void your 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 your unit. If
you suspect high levels of chlorine in your Hydrocollator Heating Unit, we recommend the addition of a
dechlorinator.
5. Certain additives (such as herbal teas, essential oils, etc.) will damage the components of the heating unit
including the stainless steel. The Hydrocollator Heating Unit was designed to heat water and HotPacs only.
To avoid potential for rusting:
1. Do not use bleach or cleaners with high chlorine content.
2. Do not use paper clips, safety pins, staples, coat hangers, etc., in or on the unit.
3. Do not clean the unit with steel wool or a carbon steel brush.
4. Do not use abrasive cleaners which tend to disturb the grain in the finish.
5. Water level is critical: Add water daily and keep it full.
6. Regularly clean and drain the tank (every two weeks).
7. Remove all deposits from interior surfaces and parts (including heating element). The deposits are
concentrations of chlorine that allow rusting to begin. If allowed to accumulate on the heating element,
these deposits will lower the efficiency of the element and increase the power consumption of the unit.
8. If you suspect that you have “hard water”, you may need to change your water more frequently. Salt deposits
are an indication of hard water that will eventually cause rust.

Cleaning Tips
1. The interior of the unit should be cleaned, usually every two weeks, using a low abrasive bathroom cleaner.
Check for low or no chlorine content in your cleaner and make sure that the residue is thoroughly rinsed
away with water.
2. A strong solution of vinegar and water will usually dissolve away deposits, which then must be thoroughly
rinsed away.
Care of HotPacs
Always return the Hydrocollator HotPac to the hot water of the heating unit after each treatment. There it
is heated, kept clean and ready for immediate use. The HotPac may be boiled; however, this hastens the
deterioration of the pack. The pack may also be cleaned by scrubbing the pack with soap and water. The
simplified method of keeping the pack clean is to keep it immersed in water.
The Hydrocollator HotPac, under constant daily use, should have a useful life of at least one year. When the pack
begins to wear out, the filler oozes and leaks through the fabric of the cloth and sections of the pack appear to
be loose and empty and will not retain heat properly. The pack should be replaced when it reaches this state.
Original replacement Hydrocollator HotPacs may be ordered from an authorized Chattanooga Group dealer.
NOTE: If HotPacs are to be stored for extended periods, they may be placed - while wet - in plastic bags and
stored in a freezer.
