Maintenance

When 90% of the setting service time has accumulated, the “STATE” LED on the control panel will

blink in yellow. (Refer to EOL settings, for bed life duration settings). If the HumidiClean is not serviced

at this time; the unit will continue to operate for the remaining 10% of the service life setting. When

100% of the bed life setting has been reached, the “STATE” LED will be on in red. The unit will drain

the tank and not respond to a call for demand.

Note: Service Life can be adjusted based on water quality. If Ionic Beds are relatively free of scale

deposits or scale is forming on tank walls and elements because beds are saturated with scale, please

consult the factory for Service Life adjustment procedures.

A. Servicing the Unit

1. Save the settings, consult the OPERATION SETUP menu

2. Go to Steam Gen. Menu

a. Drain tank by changing from “STEAM GEN.” to “MANUAL DRAIN” in the Operation

Setup Menu.

b. Once the tank is drained, shut power off to unit and allow the tank to cool.

c. Remove the cabinet access panel and tank access panel, located on left side of

humidifier.

3. Ionic Bed Inspection

Remove and inspect one of the ionic beds and inspect the drain screen at the bottom of the

tank. If the bed does not appear to be saturated with mineral deposit (a full bed will

weigh 1.1 kg (2.42 lbs) dry and if the drain screen is clear, you can reset the Ionic Bed life

timer and either change that timer or leave it as it was. Continue on to Step 4.

If the beds are saturated, remove all of them. Remove any large pieces of scale from the

tank. See Page 19 (Replacing the Ionic Beds) for complete instructions.

4. Cleaning the Unit

a. Chemically clean the unit with Rite-Qwik. (If desired.)

i. Pour 3.75L (1 gallon) of Rite-Qwik into tank followed by 3.8 L (1 gallon) of

fresh water. The HC-6500/6700 model requires 7.6 L (2 gallons) of Rite-Qwik

and 7.6 L (2 gallons) of water.

ii. Allow the solution to work until the bubbling action ceases, not to exceed 1

hour. While waiting you can proceed with Steps b, c and d.

iii. Fill the tank with water and drain. (Perform this step several times.)

b. Clean the water level electrodes, using an emery cloth. See Page 21 for complete

instructions.

c. Ensure drain lines are free of leaks and secure.

d. Check inlet screen on fill valve and remove any debris.

e. Install the new Ionic Beds once you flushed the tank out.
