Supine Bath Tub 28 Part No 1096926
Calibrating the Disinfectant Flowmeter
ƽ 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.
