Nortec NH Series installation manual NHTC/NHPC Components, Item Number Component Name Description

	Table 1.	NHTC/NHPC Components
Item Number	Component Name		Description
1	Steam Connector		Used to allow easy replacement of cylinders without disconnecting
			the steam line.
2	Condensate Return		This inlet is to return condensate to the unit.
3	Fill Cup		The fill cup allows isolation from the fill line by supplying an air gap.
			It will also overflow any water that cannot enter the cylinder to drain.
4	Float Chamber (Optional)		Detection OPTION – Used with the advanced foam detection
			setting.
5	Manual Drain Button		By pushing this button, manual drain is initiated with software
			support. Software support supplies drain cooling if enabled and will
			disable manual drain after 10 minutes.
6	Door Interlock		The door interlock prevents the unit from running when the front
			door is off. For startup and troubleshooting, pulling this interlock will
			overide this safety feature.
7	Back-up Drain		Back-up drain switch allows the draining of the cylinder without
			electronic support.
8	Fill Valve		The fill valve allows water to flow up to the fill cup. In units with
			Drain Water Cooling to 120 degrees option, this valve is a dual
			valve. The second valve is wired in parrallel with the drain valve to
			quench the water with fresh cold water everytime the drain is
			activated.
9	Drain Canal		The drain canal allows all drainable water to accumulate into one
			location to then be drained away.
10	Drain Valve		Drain valve when energized will allow water to flow down to the
			drain canal. When not energized, water flowing from the fill cup will
			flow up into the cylinder.
11	Transformer		The transformer converts the primary supply voltage to the required
			24 VAC to the unit electronics. It is protected by a fuse to ensure
			that the 24 VAC electronics are protected from surges or shorts.
12	On/Off Switch		Turns the unit power on and off. Be aware that high voltage will still
			enter the unit even though the 24VAC electronic are disabled. The
			contactor will not be energized. Main shut-off should be open before
			any servicing is performed.
13	Graphical Display and Menu		The graphical display and buttons are used to navigate through the
	Buttons		software. Use software flowchart as a reference.
14	Remote Relay Board (Optional)		The remote relay board is a set of 4 dry contacts, rated for 24 VAC
			1A, which activate in conjunction with humidifier on, steam
			production, service and error conditions.
15	NORTEC Cylinder		The NORTEC disposable cylinder contains electrodes that become
			energized when the contactor is closed. This allows current to pass
			through the water from one electrode to another, generating heat
			within the water. The water then boils and the output is clean pure
			steam.
