Danger that may arise from the unit Danger: Some components of the Nortec MH are mains powered.
One may get in touch with live parts when the control unit or the distribution boxes are open. Touching live parts may cause severe injury or danger to life.
Prevention: Before carrying out any work set the Nortec MH out of operation
(switch off the unit, disconnect it from the mains and stop the water supply) and secure the unit against inadvertent power-up.
Warning: The UV lamp used in the water treatment unit (option) emits
harmful UV-C rays.
If the UV lamp is operated outside the housing, the emitted UV-C rays may damage the eyes.
Prevention: Never operate the UV lamp outside the housing.
Warning: Badly maintained humidifiers can endanger the health.
If the unit is not properly maintained germs may grow in the water tub which can cause illness and the humidification boxes (and the mist eliminator) of the Nortec MH and may affect the air passing through the humidifier.
Prevention: The Nortec MH must be cleaned in the prescribed intervals
according to the information given. The cleaning works must be carried out correctly and the humidification boxes and the mist eliminator boxes must be replaced after their prescribed lifetime has elapsed.

• if the Nortec MH is no longer operating correctly
• if connections and/or piping are not sealed
• if electrical cables are defective
All persons working with the Nortec MH must report any alterations to the unit that may affect safety to the owner without delay.
Prohibited modifications to the unit
No modifications must be undertaken on the Nortec MH without the express written consent of the manufacturer.
For the replacement of defective components use exclusively original accessories and spare parts available from your Nortec supplier.

Functional description
The MHB Flow model provides On/Off control by means of the MHB control unit and an external On/Off humidistat. In case of a humidification/cooling request the supply valve opens and the water flows via the pressure reducing valve (accessory), the water filter (accessory) and the manually adjustable volume controlling valves to the distribution pipes above the humidification boxes.
The distribution pipes evenly supply the water to the entire surface of the humidification boxes where it flows down and humidifies the air flowing through the humidification boxes. The excess water not used for humidification flows to the water tub and then directly to the drain.

3.5.2. MHTC Flow System Overview
Figure 4. System Overview – MHTC Flow
Functional description
The MHTC Flow model provides multistep control by means of the MHTC Total Control unit and the step valves (1, 2 or 3 step valves depending on the humidifier capacity). The MHTC Total Control unit (for wall mounting) processes analog sensor/control signals and uses them to control the step valves. This allows multistep control (1 to 3 steps depending on the humidifier capacity) which improv es control accuracy compared to the MHB Flow model.
In case of a humidification/cooling request one, two or all three step valves open (depending on the request). The water flows via the manually adjustable volume controlling valves to the distribution pipes above the humidification boxes.
The distribution pipes evenly supply the water to the entire surface of the humidification boxes where it flows down and humidifies the air flowing through the humidification boxes. The excess water not used for humidification flows to the water tub and then directly to the drain. If the MHTC Flow model is equipped with the optional UV water treatment (installed in the water supply) the water is continuously sterilized during the humidification process.

3.6.2. MHB Reflow System Overview
Figure 6. System Overview – MHB Reflow
Functional description
The water tub is filled up to a preset upper level via the level-controlled supply valve. When the water level in the tub drops below a certain limit, the level-controlled supply valve opens until the upper limit is reached again. The pump is activated whenever the float is high and continues to operate for a preset time after the float level drops.
The MHB Reflow model provides On/Off control by means of the MHB control unit and an external On/Off humidistat. In case of a humidification/cooling request the pump is activated. The water flows via the manually adjustable volume controlling valves to the distribution pipes above the humidification boxes.
The distribution pipes evenly supply the water to the entire surface of the humidification boxes where it flows down and humidifies the air flowing through the humidification boxes. The excess water not used for humidification flows to the water tub. To prevent accumulation of mineral residues and the formation of germs in the water tub, the tub is completely drained periodically (interval or time controlled).
