14. SERVICE INDICATORS

Seven LED lamps provided on the front panel indicate the

functional status of the humidifier as shown in Figure 7 below.

Unplug the power cord from the 120 volt source for

S2000 (240 volt for S2020) and allow the water to cool for

at least 30 minutes prior to removal.

Turn off the water supply at the saddle tapping valve.

Remove the cable assembly wire plug from the top of the

plastic control housing.

Drain the water with the manual drain valve. NOTE: The

drain valve will be hot if the humidifier has not been

allowed to cool.

Disconnect the water and drain lines. NOTE: Some water

may drain out of the water line. Have a small container

ready to catch the water.

NOTE: Although the water has been drained, some water

may still remain in the humidifier reservoir along with

sediment. Be careful not to tip the unit over when

removing it from the duct.

Remove the eight (8) screws from the front mounting

plate.

Slide the humidifier out of the duct.

Remove the two (2) screws holding the tank baffle to the

pan flange and remove the baffle from the unit. Scrape all

mineral deposits from the baffle and wash baffle off as

described in step J. Remove the Anode from the baffle

plate and purchase a new one. Operating the unit without

the Anode will degrade the performance and increase

maintenance.

Use a putty knife to scrape the minerals from the sides and

bottom of the water reservoir. DO NOT scrape on the

small temperature probe, or the heater element. Use a soft

emory cloth or stiff nylon brush. If necessary, fill the tank

with vinegar and let it sit for several hours or even over-

night allowing the scale to soften and making it easier to

remove.

Carefully scrape the Water Level Probe to remove

mineral deposits. Use soft emory cloth if necessary.

Clean the Water Probe Insulator, inside the pan, with a

cloth and 50-50 mixture of water and vinegar, rinse with

fresh water. Inspect for any mineral deposits on the plastic

insulator. Repeat cleaning if necessary and thoroughly

dry. Use a small nylon brush to clean deposits off the

heater element and thermistor probe. Be careful not to

damage any of the components.

Rinse out the reservoir. Be careful to keep water off of the

wiring compartment and the front cover of the humidifier.

Allow the unit to dry thoroughly before using!
Reinstall the tank baffle and tighten the two (2) screws.

Re-install the unit in the duct and connect the water line and

the drain lines. Store the unit in this condition for the

summer, or continue to the next step.

START -UP

Turn on the water supply. Inspect the water connections and

drain fittings for leaks.

Plug-in the S2000 power cord to the 120 VAC (240 VAC for

S2020) grounded outlet. DO NOT use an extension cord.

1. The green POWER light should blink rapidly until it

detects a demand to humidify, then it will blink slowly.

2. If the humidistat is calling for humidity the water

valve will energize and the water pan will fill with water.

3. The Heater element will energize to heat the water, and

the Fan will start up to distribute the moisture

Maintenance and inspection of the unit requires removal

of the humidifier from the duct. This can be done

following these steps.

13. MAINTENANCE/SPRING SHUTDOWN

Proper maintenance and removal of mineral deposits is still

required on your steam humidifier in order to optimize

performance. Annual cleaning is a must and more frequent

cleaning may be necessary depending on the mineral content

of the water in your area.

A post winter cleaning and shutdown, will prevent hard

deposits from accumulating inside the bin, while the

humidifier is idle over the summer. Do not allow the unit to sit

idle for long periods without a proper cleaning and shutdown.

Failure to do so will affect the performance of your steam

humidifier.

MUST FILL WITH ABOUT THREE (3) TIMES THE AMOUNT OF WATER AS REQUIRED IN THE NORMAL

CYCLE OF FILLING. THE 'FILL TIMER' MAY TIME OUT BEFORE THE WATER LEVEL REACHES THE

WATER LEVEL PROBE CAUSING THE 'SERVICE CYCLE' TO BE STARTED. IF THE WATER FAILURE

ILLUMINATES, UNPLUG THE UNIT FROM ITS POWER SOURCE, WAIT ABOUT 15 SECONDS AND

RECONNECT THE POWER SOURCE. THE SERVICE LIGHT WILL GO OUT AND THE UNIT WILL

CONTINUE FILLING TO THE CORRECT LEVEL.
