15. Why Is Steam Better Than Evaporative The answer is: Both evaporative and steam have the same ability to humidify your home. The difference is basically in the manner in which the humidifier must be installed because of the arrangement, placement and operation of your heating and cooling system.

16. Positioning Evaporative humidification remains the best choice in the majority of installations and will remain a mainstream product. Easy to install. Reliability and long equipment life. Various consumer price points Steam humidification is an addition to our line for specific applications. Addressing these applications offer tremendous potential.

17. Its All Application Low Run Times Radiant of Hydronic Heating Ultra Dry Climates Crawlspaces Heat Pump Demands Small Equipment Closets Very Large Spaces ( High Capacity Needs) Or Any Situation Where An Evaporative or Powered Unit Can Not Be Installed.

18. Steam Expertise Electrodes are located in our canister. Electrical current flows between submerged electrodes. When the minerals* in the water within the canister come into contact with energized electrodes, current flows through that water. Resistance (of the sediments in the water) to that electric current excites (heats) the water molecules thus producing steam! Electrode Technology – How it works to make steam? * Dissolved sediments may include magnesium, iron, calcium carbonate, lime, sodium, etc.

19. 3 grains 36 grains Water is generally measured in grains of hardness 1 grain is equivalent to 64.8 milligrams of material. Grains of hardness are usually referring to calcium carbonate and or magnesium content. Very soft:0-70 ppm0-4 GH Soft:70-140 ppm4-8 GH Slightly hard:140-210 ppm8-12 GH Moderately hard: 210-320 ppm12-18 GH Hard:320-530 ppm18-30 GH Very hard:>530 ppm>30 GH

20. Water Water Everywhere More than 85% of American homes have hard water. The softest waters occur in parts of the New England, South Atlantic-Gulf, and Hawaii regions. Moderately hard and hard waters are common in many of the rivers of the Tennessee, Great Lakes, Pacific Northwest, and Alaska regions. Hard and very hard waters are found in some of the streams in most of the regions throughout the country. Hardest waters (greater than 1,000 ppm) are in streams in Texas, New Mexico, Kansas, Arizona, and California. USGS Survey Data

25. Mounting Simple mounting procedure, mount level, not required to be perfectly level. Mount on duct or remote with no additional accessories. 16.5 lbs unit weight 23 lbs when operating FrontBack Mounting Holes Do not mount in location where ambient freezing temperature may occur.

26. Remote Mounting Mount on duct or remote with no additional accessories. 6 ft of steam tube included with the unit. Cut to the length needed. Commercial Grade Steam Tube 90% of install problems are because the steam tubing was installed incorrectly.

27. Remote Mounting Steam hose will soften over time, be sure to support it properly. If water builds inside steam tube, it will create a p-trap, reducing steam that flows through and may effect overall unit capacity. Avoid a 90 degree angle

28. Remote Mounting Capacity changes with remote hose length. Recommendation is to use hard piping for distances over 6 feet, maximum combined distance is 20 ft

29. % Remote Mounting Up to 20 Ft. Portions of Supplied Hose Based on hose portions used: UP TO 18 FEET OF 1 COPPER TUBING Note: ¾ to 1 reducing coupler may be required on both ends of copper tubing. Insulating all tubing is required for maximum capacity

30. Remote Mounting Installation over an obstruction. Must install a drain line that forms a p-trap to keep the steam from escaping.

32. Duct Dispersion DRI-STEEM – Worlds leading expert on this topic. Dispersion Tube Technology at its Best Tubelets extend into the center of the dispersion tube, so only the hottest, driest steam is introduced into the duct. Any condensation forms on the outer walls of the tublet.

33. 5 Duct Dispersion This proven method is significantly better than competitive offerings; unique and different. Its easy to boil water, however precise distribution into the supply or return ductwork requires dispersion expertise. Dri-Steem is the worlds leading expert on dispersion technology. If it aint broke, dont fix it. Simply said…..

34. Cleaning No cleaning or scrubbing, simply replace! vs. SimpleNever deal with this again!

35. Canister Replacement 1.Turn power off at the unit, it will automatically drain. When draining water, inlet also opens flushing hot and cold water. NO SCALDING 2. When draining complete, kill electrical to the unit. 3. Remove the front panel. 4. Disconnect electrodes, water sensor, and hose clamp at top of canister. 5. Replace canister, strainer and o-ring (provided with new canister) Easy to Replace – Minutes Minimal maintenance – No cleaning, scrubbing at all.

36. Canister Life Canister replacement is recommended every humidifier season. Preventative Maintenance – Replace before the unit stops operating. When the canister cannot reach the correct conductivity, it will stop and wait for canister to be replaced. Failure Modes: Hard Water – Build up of calcium or deposits on the electrode. Soft Water – Zinc electrode plating will corrode. Abnormal water conditions may cause the unit to operate for months or years.

37. Fill valve Drain valve Fill cup Water supply line Power supply to electrodes Supply water enters cylinder from bottom Drain Removable canister Electrodes Steam outlet Sequence of Operation 1. Fill valve opens, flows through the fill cup and into the canister. 2. Electrodes energize, electricity travels through water causing it to boil. Fill valve opens and closes as needed to maintain operating level. 3. Steam created in the canister flows through steam hose to dispersion assembly. Fill Cup – Air gap, backflow protection, overflow protection if installed improperly Incoming water 25 psi to 80 psi

38. Power supply to electrodes Electrodes Water Conductivity Standard drinkable water is electrically conductive from the impurities, or ions in the water. Electrodes are not heating the water, as in resistive technology, the current passing through resistive water is causing it to heat. Conductive area through the water increases as more electrode is submerged in the water; therefore, current increases as water level increases. Controls water level at 11.5 amps, adjusting water to reach this level based upon conductivity of the water. +/- 10% of 11.5 amps

39. Operation and Water Conductivity Unit adjusts to the correct water level to reach nominal current (capacity). Fills and drains while steaming. Increase conductivity by increasing impurities in water. Unit boils off water and minimizes draining while continuing to refill Reduces conductivity by removing impurities in water. Drain unit and refill. or As electrodes coat with scale, more of the electrode is submerged in the water until water reaches top of canister. Control board logic makes decisions…….unit just operates.

40. Operation and Water Quality Unit operates with both hard and softened water. Recommendation is to install to hard water. Hard Water – Rule of thumb is it will operate from 3 to 36 grains of hardness. Softened Water – More conductive, minerals (scale deposits) will not build on the inside of canister, conductivity grows and it flushes more water. Reverse Osmosis/ De-ionized / Pure Water – Unit will not operate because no conductive impurities in water. Water filtration not required!

41. Draining Drain Valve Drain valve and fill valve open at the same time, always tempering water. Water temperature is under 140 degrees, on average, high temp condensate pump not required. Robust Design – Safety /Prevention If plenum pressure exceeds 4 W.C. or hose is kinked, water will push back into the fill cup. Install to cold water Condensate Pump available Part # 4856 (160 degree spec – no issues) 80% of water used goes to steam, 20% drained

42. Draining Designed to greatly reduce opportunity to plugging. Large drain opening Strainer in canister helps to catch debris Drain valve pulses to further reduce opportunity to plug. If unit is trying to drain and conductivity does not change, unit knows something is wrong, shuts down, and activates service light. Large drain pan for overflow and leak protection.
