SAVE THESE INSTRUCTIONS

WARNING

DO NOT use this product or any available optional equipment without first completely reading and understanding 

these instructions and any additional instructional material such as owner’s manuals, service manuals or instruction 

sheets supplied with this product or optional equipment. If you are unable to understand the warnings, cautions or 

instructions, contact a healthcare professional, dealer or technical personnel before attempting to use this 

equipment - otherwise, injury or damage may occur.
The disinfectant dispensing system has been factory tested and calibrated for use with Invacare disinfectant. The use 

of any disinfectant with a dilution ratio (½ oz per gallon) or viscosity level different than that of Invacare disinfectant 

will result in an improper mixture of disinfectant and water. This may cause your system to be improperly 

disinfected - or in some instances, not disinfected at all. If using any disinfectant with a dilution ratio or viscosity level 

different than that of Invacare disinfectant or if switching from one type of disinfectant to another type, the 

disinfectant flowmeter MUST be calibrated using this procedure before disinfecting the tub.
This procedure should only be attempted by qualified maintenance personnel. Failure to heed these precautions 

could result in injury to the tub operator or resident.
ALWAYS wear rubber gloves, an apron and face shield protection during disinfecting, cleaning and rinsing 

procedures. In case of eye or skin contact, follow procedures on disinfectant container.

CAUTION

NEVER use abrasive cleaners like scouring powder or liquid cleaners containing pumice stone. The use of these 

types of cleaners will make the gel-coat finish of your tub scratched and dull. NEVER use cleaners containing iodine, 

bromine, Betadine

®

 or methylene blue. The use of these types of cleaners will cause the tub to stain. Never use 

cleaners containing bleach. Use of these types of cleaners will dry out the rubber seals and gaskets and the tub will 

not function properly.
