1. Measuring the Electrolyzed Water Concentration
Adjust so that the electrolyzed water concentration is within the prescribed range in order to maintain the
performance of the space cleaning system.
(1) Preparing to measure the concentration
After replacing the Virus Washer element and scale filters, and after cleaning the electrolyzed water tray, fill the
water tank with water and install it in the unit. Next, press the ON/OFF button and turn the system ON, then
OFF. Cleaning operation will begin immediately. Wait approximately 20 minutes, until the circulating pump stops

the electrolyzed water tray. Add the water into the container that is supplied with the residual chlorine
concentration meter.
Add the water sample into the
container supplied with the
residual chlorine concentration meter.
Sampling the circulation water
(3) Use the syringe (for purified water) and obtain 9 mL of purified water. Add this purified water into the container
that is supplied with the residual chlorine concentration meter, and mix it with the water sample.
Add the purified water into the
container supplied with the PDP.
Obtaining purified water
(4) Insert the provided container into the residual chlorine concentration meter, and press the “ZERO” button.
