are designed for water pressure from 30 to 80 psi and are protected by the built-in strainer. WATER SUPPLY AND PLUMBING 1. The fill valve is sized for an extended water pressure range of 30 to 80 psi. 4. For inlet water pressure outside this range, the factory should be contacted. (See Water Supply and Plumbing section of this manual.) 2. For cases below 15 psi add a pressure boost pump, notify the factory and a fill valve with an oversized orifice will be supplied. START-UP AND OPERATION 3.
Figure #4 MES-P Adjustable Pot The red light simply acts as a safety to shut off the fill valve and prevent over-filling. With the red light on, the water in the cylinder will continue to heat and, after a few minutes, start to boil. After the boiling action of the water has lowered the water level below the sensor at the top of the cylinder, the red light will go out and the fill solenoid will again open until the cylinder is again full.
dependent on water supply conditions and humidifier usage. Failure to replace the cylinder at the end of cylinder life may result in unit damage. NORTEC is not responsible for any damages resulting from, or attributable to, the failure to replace a used cylinder (see Manufacturer’s Warranty). INSTALLING THE NEW CYLINDER 1. The reverse procedure should be followed to install a new cylinder. The main disconnect is to be left open until the cylinder is completely installed and reconnected.
FOAMING: The phenomenon which can occur in water when the impurities, already in the water reach an excess concentration as a result of boiling away pure water and the continued boiling action agitating the contained water. The humidifier electronics are designed to prevent this occurrence although in extreme cases, water will foam with little concentration making it necessary to have the drain time of the water, contained in the cylinder, increased.
Water remains at high level and won’t concentrate: This is normal on cold start-up and can be accelerated by adding maximum 1/2 tsp. of dissolved salt to the cylinder (through the plastic fill cup) on fill cycle. See “Low Water Conductivity” section of this manual. If unit has been operating extensively, observe for normal fill-boil-fill-boil cycle; no drain should be occurring. If drain occuring, check for leaking drain valve or back pressure.
DIAGNOSTIC PROCEDURES - TROUBLESHOOTING GUIDE Unit Status Lamp Yellow On Green On Symptom Corrective actions Maximum water level This usually happens on initial start-up after replacing the cylinder inside cylinder. (normal). Water is concentrated with minerals inside the cylinder. Let unit run, yellow light will disappear when the unit is at full output. This may take a day or two. Off Off No power to the board. Check for main power supply fault. Turn power switch to ‘Drain’ position.
