Disinfecting The Tub Using The Closed Loop System - Invacare 3600 Owner's Operator And Maintenance Manual

Disinfecting the Tub Using the Closed Loop System

• 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.
• 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 3.1.
NOTE: Ensure that the whirlpool jets and whirlpool inlet fitting are closed before starting this procedure.
1. Clean the entire tub surface to remove visible tissue residue and fluid.
2. Depending on the type of whirlpool jets that are in your tub, close all jets by performing one of the following:
• Turn the center of the jet clockwise to a full stop.
• Push the center of the jet in.
3. Close the whirlpool inlet by gently pulling the plug in the center of the inlet cover outward until it stops.
4. Open aerator by rotating aerator knob two turns counter‐clockwise.
5. Open disinfectant cabinet.
6. Ensure that disinfectant siphon tube is placed in disinfectant container.
7. If tub is equipped with a disinfectant wand, hold the wand over the interior of the tub.
8. Adjust water temperature to 105°F (40°C).
9. Turn disinfectant On/Off valve to the On position.
NOTE: Liquid will begin flowing from the disinfectant wand into the tub (if so equipped).
10. Turn the adjustment knob on the flowmeter until the floating ball rises to a level of 35 cc/min.
NOTE: At 35 cc/min., disinfectant is being mixed with water at the proper ratio.
11. Continue to hold the disinfectant wand over the
interior of the tub (if so equipped).
NOTE: When disinfectant has totally filled the interior plumbing,
liquid will begin to flow from the burp fitting located inside the tub
bowl near the rim or from the disinfectant wand.
NOTE: Invacare recommends that you thoroughly scrub all
interior surfaces of the tub with disinfectant. The use of a long‐
handled brush will make this operation easier.
12. Perform one of the following:
• Allow some liquid to pool in the bottom of the
tub. Scrub all interior surfaces of the tub,
including the whirlpool jets, overflow fitting and
whirlpool inlet fitting with disinfectant.
• If the tub is equipped with a disinfectant wand,
spray the interior surfaces of the tub, including the
whirlpool jets, overflow fitting and whirlpool
inlet fitting with disinfectant. Scrub all interior
surfaces.
13. Turn the disinfectant valve to the Off position.
14. Return disinfectant wand to its holder (if so equipped).
15. After scrubbing the interior surfaces, leave the
disinfectant in the loop and on the tub surfaces for ten
minutes.
16. Reverse STEPS 2 and 3 to open the whirlpool jets and
inlet.
17. Set the shower/massage wand to the pulse setting and
direct the spray into both whirlpool jets to back flush
until the water discharging from the whirlpool inlet is
clear.
18. Rinse all interior tub surfaces.
