SECTION 3—OPERATING INSTRUCTIONS
Part No 1118387 23 Side Entry Whirlpool Tub
Disinfecting the Tub Using the Closed Loop System
ƽ WARNING
Disinfect the tub after EACH use to avoid resident infection and contamination of the tub.
DO NOT disinfect the tub when it is occupied otherwise injury may occur.
Read and understand all information on Invacare brand disinfectant before use.
ALWAYS wear rubber gloves, an apron and a face shield when using disinfectant. In case of eye or skin contact,
follow procedures on disinfectant container.
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 before performing this procedure. Refer to
Calibrating the Disinfectant Flow Meter
on page 32.
DO NOT use the disinfectant wand for showering. The disinfectant wand is to be used for disinfecting ONLY.
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.
