INSTALLATION RECEIVING & UNPACKING EQUIPMENT 1. Check packing slip to ensure ALL material has been delivered. 2. All material shortages are to be reported to NORTEC within 48 hours from receipt of goods. NORTEC assumes no responsibility for any material shortages beyond this period.
LOCATION & MOUNTING HUMIDIFIERS NH Series humidifiers are designed to mount on a suitable wall or vertical surface. Do not sit on floor due to clearances required for plumbing, electrical, and control entrances. The clearance dimensions shown in this manual are for reference only and are the minimum required for maintenance of the humidifier.
safety thermostat to turn off the humidifier if the blower pack gets overheated. Control thermostat, mounted on the steam distributor, starts the fan when steam is generated. When supply voltage differs from voltage required to run blower motor, blower pack will contain a proper transformer.
has been improved to prevent backup despite long or gently sloped drain lines but it can not compensate for flat or uphill runs. 2. The drain line should not end in a sink used frequently by personnel, or where plumbing codes prohibit it. Route to a floor drain or equivalent for safety reasons, since drain water from humidifier can be very hot.
LOW VOLTAGE CONTROL WIRING On-Off Controls Controls are available from NORTEC as accessories. If controls were not ordered with humidifier, they must be purchased supplied by others. The following information is relevant to all controls, factory supplied or otherwise.

5. Field-wiring connections for modulation control are to be made to external side of terminals 26, 28, 30 and 32 on humidifier’s control terminal strip. Always refer to the external control’s wiring diagram factory supplied with each NORTEC modulation control option.

USER LEVEL The keypad has four keys: MENU, é , ê , ENTER. Each time the user presses the menu key, the microcomputer will display on the LCD the next operating parameter on the menu.
MANUAL CAPACITY ADJUSTMENT The NHB humidifier is rated in lbs/hr of steam output capacity. Set to 100%, it will operate at full output until the humidistat has sensed that the humidity has reached setpoint. Then it will stop the humidifier by breaking control circuit 8-10.
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).

messages, instead of two, as summarized in Figure #14. 5. When both the yellow and the green status lamps are on, the water level is detected as being at the top of the cylinder. This is normal on start-up, but as the contained water concentrates, the water will stabilize at a lower water level and the yellow lamp will be off.
6. Remove snap-fit red cap from coil assembly and slide coil off the actuator. 7. Loosen actuator with wrench and unscrew from plastic valve body. 8. Clean the exposed core and spring and plastic drain valve port. 9. Important: Tapered end of spring must be installed toward the solenoid.
This feature will reduce the possibility of corrosion of the electrodes and the possible accumulation of algae and bacteria growing in the cylinder. BUILT ON AND REMOTE MOUNTED BLOWER PACKS (BOBP’s / RMBP’s) FAN MOTOR OILING: The blower pack fan motor requires occasional oiling of motor bearings.
Clean the drain valve; start with a fresh cylinder. Then measure the manual drain time with and without the external drain connected. Is the external drain impeding flow? NORTEC recommends an open external drain line.
Response: See Figure #2, NHMC/NHP System Messages 4. Max. Filling Time - Error 3 Symptom(s) Diagnosed: Time dependent. Neither Maximal Level (full cylinder) is detected, nor is there enough current drawn to meet capacity demand. Current monitored on primary lead to cylinder is greater than zero and not decreasing.
1. No current being drawn on the monitored primary lead to the cylinder, or the actual current is not being sensed. 2. Water does not reach the electronics due to a restricted water supply line or due to a constantly open/leaking drain valve preventing a water level increase.
9. Phase Interrupt - Error 8 (NHMC only) Symptom(s) Diagnosed: The 24 VAC to the main PCB, across terminals 44 and 46 is interrupted. Probable Cause(s): a) A wiring problem leading to an interruption of the 24 VAC to terminals 44 and 46 of the main PCB.
2. Max. Filling Time Symptom(s) Diagnosed: The fill valve has been “on” for a longer time than is normally required for non-zero current to flow between the electrodes or for water level in the cylinder to reach the high water sensor pin.
Supply water pressure is too low (less than 30 psig). 7. Electronics Symptom(s) Diagnosed: When on/off/drain switch is switched on, green status lamp does not come on. Probable Cause(s): Green status lamp is damaged. (Long life LED should never burn out.
high water sensor board has a primary voltage side. One leg connects to the primary leg; one leg connects to the short sensor pin in the top of the cylinder. A potential, somewhat less than primary, is picked up by the sensor at high water level, which “makes” the red/black circuit on the low voltage side.
