Calibrating the Disinfectant Flow Meter

SECTION 4—SAFETY INSPECTION/TROUBLESHOOTING

WARNING

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 disinfect- ing, cleaning and rinsing procedures. In case of eye or skin contact, follow proce- dures on disinfectant container.

NOTE: For this procedure, refer to FIGURE 4.1 on page 33.

NOTE: Equipment needed:

•Bucket or Pail, at least 1 Gallon

•Graduated plastic bottle, at least 16 ounces

•Felt Tip Pen

1.Open the whirlpool aerator by rotating two turns counterclockwise.

2.If the tub is equipped with a disinfectant wand, hold the wand over the interior of the tub.

3.Pour exactly one gallon of water into the bucket/pail.

4.Mark the bucket/pail at the gallon level using the felt tip pen.

5.Empty the bucket/pail.

6.Pour a whole number of ounces of disinfectant into the graduated plastic bottle.

NOTE: For example, pour 2 or 3‐ounces, but not 2½‐ounces, otherwise the results will be skewed.

NOTE: DO NOT use water instead of disinfectant. This would cause a false reading.

7.Note the number of ounces in the graduated plastic bottle.

8.Open the service access cabinet door.

9.Insert the disinfectant draw tube into the graduated plastic bottle.
