MS2000 MiniSteam Residential Owner’s Manual Installation - Mounting the Humidifier 1. Open the carton and carefully remove the humidifier and accessories. 2. Open the humidifier, using a flat blade screwdriver, and remove the mounting hardware and accessories. 3. Remove the plastic steam cylinder by loosening the clamp on the top left of the cylinder and lifting the cylinder while twisting it up out of its base. a.
MS2000 MiniSteam Residential Owner’s Manual 4. Locate where you will install the duct steam nozzle in the duct (if used), and then decide on a convenient location for the humidifier, that will permit the hoses to be sloped properly. 5. Use the mounting bracket to mark the wall for drilling. Use a level to insure the unit will hang level. (See Figure 4 at right) CAUTION: make sure that the screws will go into wall studs to support the weight of the humidifier. Figure 4 Figure 5 Figure 6 6.
MS2000 MiniSteam Residential Owner’s Manual Figure 7 9. Remove the mounting bracket from the back of the humidifier Mount the humidifier unit as close to the steam distributor pipe as possible to minimize condensate. Mount the humidifier unit below the steam distributor pipe whenever possible. Insure that a slope can be maintained in the steam hoses.
MS2000 MiniSteam Residential Owner’s Manual 10. Hang the humidifier unit carefully on the mounting bracket. (See Figure 9 at right) Figure 9 11. Secure the bottom of the humidifier unit to the wall using the third screw. (See Figure 10 at right) Figure 10 Systems, L.L.C.
MS2000 MiniSteam Residential Owner’s Manual Installation - Mounting the Steam Nozzle 12. Locate a suitable position for the steam nozzle per Figure 11 at right. a. Locate the nozzle at least 18" upstream of any duct takeoffs or elbows. b. If the steam nozzle is installed from the bottom of the duct, locate it in the center, and cap off the condensate outlet nipple. 12. Cut or drill a 2-1/2" hole in the side of the duct to fit the steam nozzle. Figure 11 Figure 13 14.
MS2000 MiniSteam Residential Owner’s Manual Installation - Running the Steam Hose Figure 14 CAUTION: 90% of all operational problems with the MiniSteam humidifier can be traced to improper installation of the steam hose. It is very critical that steam be allowed to flow freely from the humidifier unit to the steam nozzle, and that condensate can flow back. A 20% slope must be maintained from the humidifier unit to the steam nozzle.
MS2000 MiniSteam Residential Owner’s Manual 18. Bring the end of the steam hose through the hole in the top of the humidifier cabinet and slip the end over the steam cylinder outlet. Secure the hose using the stainless the steel hose clamp supplied. (See Figure 17 at right) Figure 17 Figure 19 20. Bring the end of the condensate hose through the smaller hole in the top of the humidifier cabinet and cut it so it ends in the drain pan of the humidifier. (See Figure 19 above) Figure 18 18.
MS2000 MiniSteam Residential Owner’s Manual Installation - Plumbing IMPORTANT: Softened water with conductivity less than 250 micromhos may be used. Raw water is always recommended. Demineralized water may NOT be used. 21. Run 1/4" OD copper tubing from the water source to the bottom of the humidifier unit. 22. Attach the 1/4" OD copper water tubing to the compression fitting mounted in the plastic water fill fitting. (See Figure 20 at right) Figure 20 Figure 21 Figure 22 23.
MS2000 MiniSteam Residential Owner’s Manual Installation - Power Wiring 25. Feed power wires through one of the electrical inlets located on the bottom of the humidifier unit, and tighten the strain relief. (See Figure 23 at right) 26. Insert the wires into the proper power wiring terminals and tighten all wires carefully. Figure 23 CAUTION: loose wires can cause fires. Make sure power supply matches unit label. (See Figure 24 at right) Figure 24 11 Systems, L.L.C.
MS2000 MiniSteam Residential Owner’s Manual Installation - Control Wiring 27. Mounting the airflow switch: Mount the airflow switch in the supply or return duct using the screws supplied. Mount the device so that the diaphragm is in a vertical position as shown in Figure 25 below. Put no more than 2" of tubing into the duct. Caulk around the tubing where it enters the duct. The low pressure tap is left open to atmosphere. Reverse the taps if on the return duct.
MS2000 MiniSteam Residential Owner’s Manual 29. Run control wiring from the humidistat and air flow switch, to the humidifier unit and enter one of the electrical connection fittings on the bottom of the humidifier unit. 30. Tighten the strain relief connector around the wires. 31. Connect the wires per one of the following control wiring diagrams, directly to the bottom of the circuit board. Figure 26 is the standard wiring diagram.
MS2000 MiniSteam Residential Owner’s Manual Start up and Check out of the SD 2000 Humidifier Startup Checklist: ❑ 1. Water and drain lines are connected properly. Fittings are tight. ❑ 2. All power connections, including internal ones, have been checked to insure tightness. ❑ 3. Wires to the electrodes on top of the cylinder are tight. ❑ 4. Steam and condensate hoses are properly installed and supported to prevent sags. Hose clamps are tight. ❑ 5.
MS2000 MiniSteam Residential Owner’s Manual Operating your MiniSteam Humidifier Sequence of Operation. (Figure 28) On a call for humidification, the controller (R) will activate the power contactor (A) in the humidifier to put power to the electrodes in the steam generating cylinder (B). After a few seconds, the fill valve (C) will be activated for a minimum of several seconds to admit water to the fill cup (V) and read the conductivity (T).
MS2000 MiniSteam Residential Owner’s Manual The MiniSteam Controller Your MiniSteam humidifier has one of the most advanced controllers of any humidifier. It automatically controls drain and fill rates for the most efficient operation possible. The front of the controller provides a graphic to show unit operation, and three buttons to control functions. Setting Maximum Steam Output: Press the UP key (#2 fig 29) until the appropriate LED on the output graph lights up.
MS2000 MiniSteam Residential Owner’s Manual The Main Control Board Inside your MiniSteam humidifier is the main control board. It has similar functions to the keypad on the front of the unit. Figure 30 Setting Maximum Steam Output: Press the UP key until the appropriate LED on the output graph lights up. Once for 30%, two times for 50%, three times for 75%, and four times for 100%. This setting can be used to reduce the output of the humidifier for applications where the full output may not be needed.
MS2000 MiniSteam Residential Owner’s Manual Maintenance Although your MiniSteam humidifier is designed to take care of its normal operation, and even to provide you with diagnostic capability, good operation always means good maintenance. Periodic cleaning or replacement of the steam generating cylinder, and cleaning of the fill and drain valves is required as indicated by the controller with a “worn out cylinder alarm.
MS2000 MiniSteam Residential Owner’s Manual Cleaning the fill and drain valves: After shutdown and removal of the steam cylinder, shut off the water supply to the humidifier, disconnect the water supply and remove the fill valve from the humidifier. Remove the inlet strainer by reaching up into the fill valve inlet with a pair of needle nose pliers and pulling out the strainer by its tab.
MS2000 MiniSteam Residential Owner’s Manual Alarms and Fault Conditions When an alarm appears, it must be cleared by pressing the RESET button on the controller. If the alarm condition still exists, the alarm will continue.
MS2000 MiniSteam Residential Owner’s Manual ERROR POSSIBLE CAUSES POSSIBLE CORRECTIONS Lack of water: the fill valve has remained energized for more than 20 minutes without any increase in amperage - water turned off fill valve obstructed fill strainer obstructed no power to fill valve - Faulty drainage: the drain valve remains open for more than 2 minutes without a decrease in water level - drain valve obstructed mineral bridge in cylinder cylinder screen clogged no power to drain valve - check
MS2000 MiniSteam Residential Owner’s Manual Other Trouble-Shooting Hints: 1. The water in the cylinder turns black: This is usually an indication that the minerals in the cylinder have over-concentrated and the pH of the water has dropped causing a deterioration of the electrodes. Left unchecked, this will lead to a very short cylinder life. Check for low spots or kinks in the steam hoses that could cause a back pressure on the cylinder. Check the duct static pressure.
