  1. TrueSTEAM™ Humidification Systems Module 7: Maintenance and Service

  2. Module 7: Maintenance and Service • Maintenance • Understanding cleaning cycles • How to manually clean TrueSTEAM • How to replace the water filter • Service • How to identify fault root causes • How to fix faults

  3. Cleaning Cycles • Designed to dilute the concentration of water hardness in the TrueSTEAM tank • Automatic cleaning cycles • Remove concentration of dissolved minerals still in the water, which slows the accumulation of solid mineral scale and sediment • Manual cleaning cycles • Remove concentration of dissolved minerals • Allows user to clean out solid mineral scale and sediment

  4. Manual Cleaning Step 1: Indication • PRES • S EMPTY blinks to indicate manual cleaning is required • Note, TrueSTEAM will still operate even when this light is blinking • Press and hold the EMPTY button until the CLEAN TANK light begins blinking • This indicates a flushing cycle has initiated • When CLEAN TANK is on solid • Flushing cycle is complete and tank is empty • The tank is now safe to remove

  5. Manual Cleaning Step 2: Tank Removal • Turn red handle counter-clockwise to “Unlock’ position • Release solenoid by pushing back on grip • Grip tank bottom • With other hand, press down cover handle release, and pull handle forward

  6. 1. 2. Manual Cleaning Step 3: Cleaning • Tank cleaning • Use tap water to flush loose sediment from tank • Apply cleaning agent (list below) to cloth or paper and scrub residual scale from tank walls • Screen is removable for cleaning • Tank is dishwasher safe • Recommended cleaning agents • CLR • Lime-Away • White Vinegar • Do not use hydrocarbon oil based • Element cleaning • Apply cleaning agent and let soak for 10 minutes • Carefully rub scale off with cloth or paper

  7. Manual Cleaning Step 4: Reconnect Tank • Ensure sensor compartment fill holes are clear of debris. • Ensure gasket is properly seated in chassis before reconnecting tank.

  8. 1. 2. 3. Manual Cleaning Step 4: Re-Engage Tank • Attach the tank by securing the latch. • Engage the white water valve to the tank’s black spool, then turn the manual shut-off valve to the “Lock” position and plug in the power cord. • Check that TrueSTEAM is still mounted level and is securely in place on the mounting bracket.

  9. Changing the Water Filter • Replace the inline filter at least per season: • Turn the water supply off at the saddle valve or T-fitting. • Press down filter collar ring and pull out ¼” water line from each side. • Insert the ¼” lines into new filter. Apply modest pull to ensure a tight fit. • Secure the new filter in place.

  10. Inspect Water Level Sensor CAUTION: Electrocution hazard. TrueSTEAM must be unplugged before removing the cover. • Remove T20 Torx screw, then slide cover out front. • Remove T30 Torx screw and lift hinge and remove sensor assembly for inspection. • - If excessive debris is present, replace sensor pack: • Replacement sensor part #50027998-001 • Also available bundled with water filter #50042822-001

  11. Final Maintenance Steps • Clear duct from ventilation holes and debris from drain tube. • After cleaning, initiate a humidity call and check that there are no water or steam leaks on TrueSTEAM or the water lines. • While on vacation, it is recommended you turn the humidity control to ‘off’. • TrueSTEAM will drain and remain empty after 48 hours without a humidity call.

  12. Service and Diagnostics
