To avoid potential for rusting:
Do not
use bleach or cleaners with high chlorine content.
Do not
use paper clips, safety pins, staples, coat hangers, etc., in, on, or near the unit.
Do not
clean the unit with carbon steel wool or a carbon steel brush. Use only soft cloth, Scotch-Brite™ type
scouring pads of green, blue, or white abrasiveness, or stainless steel wool if absolutely necessary.
Do not
use abrasive cleaners which tend to disturb the grain in the finish, especially on the exterior of the
unit. For exterior cleaning, use only non-abrasive stainless steel polish.
Water level is critical: Add water daily, if necessary, to keep unit full.
Regularly clean and drain the tank
(every two weeks)
. Failure to properly maintain the unit will cause
premature wear and will void the warranty.
Remove all deposits from interior surfaces and parts. The deposits are concentrations of minerals that will
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. Exercise extreme care if cleaning
the element or thermostat(s). These components can be easily damaged without proper care or caution.
If you suspect that you have “hard water”, you may need to change the water and clean the unit more
frequently. Salt deposits are an indication of hard water that will eventually cause rust.
Cleaning Tips
The interior of the unit should be cleaned, at least every two weeks, using a low abrasive bathroom cleaner
with a soft cloth or green, blue, or white Scotch-Brite™ type scouring pad. Stainless steel wool may be used if
necessary, but not regular carbon steel wool. Check for low or no chlorine content in your cleaner and make
sure that the residue is thoroughly rinsed away with water.
A strong solution of vinegar and water may be used to dissolve away deposits, which then must be
thoroughly rinsed away. Results may vary.
For exterior cleaning, use stainless steel polish and a soft cloth only. Numerous industrial stainless steel
polishes are available from various supply companies. Use of any cleaner except stainless steel polish on the
exterior of the unit is not recommended. Abrasive cleaners and scouring pads can damage the finish of the
unit.
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; 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.
