Calibrating the Disinfectant Flowmeter
Maintenance Instructions
For Invacare Continuing Care Group Tubs
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.
NOTE: For this procedure, refer to FIGURE 1 on page 2.
