SE INDOOR INSTALLATION
LOCATING AND MOUNTING
SE Series humidifiers are designed to mount on an SE Stand (Included with all models) or floor. The clearance dimensions shown in this manual are for reference only and are the minimum required for maintenance of the humidifier. Local and National
Codes should be consulted prior to final location and installation of the humidifier. NORTEC cannot accept responsibility for installation code violations.
· Figure #1 shows the locations of all required connections to the Steam Exchange Humidifier.
Careful consideration should be given to all of these connections when choosing a location for the humidifier.
· For front and side clearance requirements (for access during installation, maintenance and troubleshooting), refer to pages 3 - 6.
· DO NOT locate humidifier any further than absolutely necessary from steam distributor location. Net output will be reduced as a result of heat loss through steam line. Also, increased static pressure (over 12" W.C.) will result in hot water going down the drain. Consult factory if this situation occurs.
· Where possible, mount humidifier at a height convenient for servicing.
· Ensure the humidifier is mounted level.
Figure #1
Primary Wiring to Humidifier
· Ambient temperature location for humidifier:
41ºF - 104ºF (5ºC - 40ºC).
· Relative humidity location for humidifiers:
5% rh - 80% rh.
· DO NOT mount humidifier on hot surfaces.
· DO NOT mount humidifiers in an area where freezing may occur.
· If humidifiers are mounted on roof, a properly ventilated, temperature controlled, (above freezing), weatherproof model should be used.
Consult your local representative for more information on NORTEC’s SETC Outdoor model.
· DO NOT mount humidifiers on vibrating surface.
Consult factory.
· The humidifier shall not be installed directly on carpeting, tile or other combustible material other than wood flooring.
· Some insulating materials may be combustible.
Prior to installing this appliance examine the area for insulating material. If this appliance is installed in an insulated space, it must be kept free and clear of insulating materials. If insulation is added after the appliance is installed, it will be necessary to examine the area again.
PRIMARY WIRING
All work concerning the electrical installation must be performed by qualified personnel.
- 13 -
ELECTRICAL
WARNING: The electrical parts inside the humidifier are very sensitive to electrostatic discharge.
Appropriate measures against electrostatic discharge
(ESD protection) must be taken when carrying out installation work.
· The humidifier should only be connected to primary power (main power) after all installation work has been completed.
· An external disconnect switch(by others) must be installed close to the unit to allow for power interruption during servicing and/or maintenance.
· Humidifiers require field wiring to primary voltage terminal blocks. Power requirement must be
110-120/1/60Vac, 15A or 20 A for SETC Outdoor
950 &1050 separately fused circuit, single phase.
Wiring can be fed through a 7/8" hole on the bottom or the top of the control compartment.
· When installed, the appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National
Electrical Code, ANSI/NFPA 70, and/or the CSA
C22.1 Electrical Code, if an external electrical source is utilized.
· External wiring sizes must be in accordance with
NEC and/or CEC and existing local electrical codes and by-laws.
LOW VOLTAGE CONTROL WIRING
(See Page 14 for details)
All SE models require at least one type of input control signal for unit operation. Refer to the sections below that detail the types of controls that can be used with each model.
Low voltage control terminal strips are provided in the electrical compartment. Refer to the specific control wiring diagram supplied with each unit.
Field wiring from humidistat to humidifier and between devices should be shielded 18 AWG or heavier and kept as short as possible.
Controls are available from NORTEC as accessories and can be ordered with the humidifier.
Controls by others may also be used as long as they meet the criteria noted below. The following is a summary of the common types of controls that may be used with NORTEC SE Humidifiers.
A – Wall or Duct Mounted Control On/Off
Humidistat: Wired to make on drop in humidity, break on rise to set point. Set to desired RH. Can be a make/break set of contacts from a Building
Management System.
B – Duct Mounted Safety High Limit On/Off
Humidistat: Wired to make on drop in humidity, break on rise to safety set point. Set to approximately 85%
RH as a safety to prevent saturation and wetting in the duct. Highly recommended for ducted applications.
C – Duct Mounted Safety Air Proving On/Off
Switch: Wired to make when sensing air flow, break when no air flow. Used as a safety to prevent saturation when there is no air flow. Highly recommended for ducted applications.
D – Wall or Duct Mounted Modulating Humidistat:
Provides a modulating signal to the unit that represents the output (up to 100%) required from the humidifier. Signal type can be changed in the field via dip switch settings on the logic control board. Refer to
SETC Setting section.
The SETC can accept a single or dual control signal. The SEP can only accept a single control signal:
0-20 mA
4-20 mA
0-10 VDC
2-10 VDC
0-5 VDC
1-5 VDC
ON/OFF
SETC
4-20 mA
0-10 VDC
ON/OFF
SEP
The unit must be ordered from the factory for the desired signal type and number of channels. If no signal type was specified, ON/OFF control signal will be set as default. When configured for 2-channel modulation the humidifier will generate steam only if both channels indicate a demand (see D). If both channels are demanding steam the humidifier will satisfy the lower demand signal.

CONTROL INSTALLATION
· Mount any wall humidistat (control or high limit) over standard electrical box at height similar to typical thermostat. Any wall humidistat should be in location representative of overall space being humidified and not in path of blower pack or air supply grille. Do not mount on an outside wall where temperature fluctuations can affect control response. (Windows, sky lights, sinks, coffee machines, etc.)
· Mount duct humidistat in location representative of overall air humidity, usually in return duct. Do not mount it directly in front of steam distributor or in turbulent or mixing zone. Mount humidistat where air’s humidity and temperature are uniform and representative of spaces being humidified.
· Mount duct high limit humidistat downstream of steam distributors far enough that, under normal humidity and air flow conditions, steam will have been fully absorbed (typically at least 10 feet). It must be located to sense high humidity only when uniform and representative air is over-humidified or approaching saturation.
· Mount duct air-proving switch so that it is able to sense air flow or lack thereof it. Wire it to make when air flow is sensed and break when air flow fails.
· Check operation of all on/off controls before starting humidifier.
· Calibration of controls (on/off or modulation) in the field may be necessary due to shipping and handling. Verify humidistat accuracy before commissioning system.
PLUMBING
NOTE: All water supply and drain line connections should be installed in accordance with local plumbing codes.
WATER QUALITY
· The humidifier is intended to operate on cold water.
· DO NOT use a hot water source to supply the humidifier. Minerals will adhere more easily to surfaces and the fill valve’s small flow regulating orifice could become plugged.
· Consider using a water softener. Longer operating times between tank cleaning will be achieved with softened water.
· Reverse osmosis (RO) water can provide very long periods before cleaning is required since it is cleaner than softened water. Deionized (DI) water may be used with all models with the stainless steel water supply option. Consult your
NORTEC representative for a quote on a water treatment system.
FILL WATER SUPPLY LINE
· Each unit is supplied with an adapter for the fill valve (½”NPT ). The SE 50-675 has a fill rate of
10l/min (2.6 gpm) and the SE 950-1050 of
17l/min (4.5gpm). Size of piping is a minimum ½” copper, recommend ¾” up to within 4 feet of unit.
· Standard fill valves are sized for water pressure ranging from 30 to 80 psig (ideally 55 to 60 psig).
For other pressures, consult factory. This pressure should be measured at the humidifier if the water pressure is suspect.
· It is recommended to have a faucet installed close to the humidifier to allow quick filling of the system on initial start up. This can also be very useful for mandatory cleaning of the unit.
· ALWAYS supply and install a shut-off valve and union in the water supply line dedicated to the humidifier to facilitate servicing.
Figure #2
Installation
- 17 -
DRAIN LINE
· The humidifier is equipped with a ¾”O.D. drain outlet connection on the side of the humidifier. A vacuum break valve is installed internal to the unit on the drain line. The drain water line must be piped to a drain funnel to provide an air gap before connection to the building drainage system.
· 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. Internal drain water tempering will ensure a maximum of 140ºF
(60ºC) exiting water temperature.
· Keep drain lines as short as possible. Keep drain lines sloped down, not level and not up since low spots in drain lines will accumulate sediment and cause backup. The drain line should be 1-1.5"
O.D. or larger. Consult local codes.
· When the drain pump is activated, the tank drains at a rate of 7-8 gal/min (18-20 l/min).
STEAM CONDENSATE OUTLET
MODEL OUTLET
SE 50, 100, 175, 250 and 375 ¾” NPT
SE 475, and 675 1” NPT
SE 950, and 1050 1 ¼” NPT
· The SE humidifier has a condensate return line connection for removal of the condensate formed in the heat exchange.
· Condensate line after the steam trap(s) must be atmospheric and lower than the traps at all times.
If required, a condensate pump (by others) can be used to return condensate to the humidifier.
AUXILIARY DRAIN OUTLET
· An auxiliary drain port is also provided on the side of the humidifier. It can be used to manually drain the unit, if required. The unit is shipped with this connection plugged. It is recommended to install a shut off valve on this line.
· The auxiliary drain port is used when the freeze protection option is required. Install a shut off valve on this line and pipe to the drain funnel.
The manual shut off valve must always be in the open position when the unit is operating but can be closed for servicing of the unit.
- 18 -
STEAM LINES AND CONDENSATE LINES
For steam line installation between the humidifier and distribution system, consult the distribution system installation manual. Steam Distributor Installation
Manual - Form #XX-231 and SAM-e, Short Absorption
Manifold - Form #XX-249.
The SE series of Steam Exchange humidifiers can develop steam pressures up to 12” w.c. to overcome duct and steam line pressures. An enclosed trap on the drain line prevents steam from going to drain.
Duct pressures above 12” will cause steam to exit through the drain line. Consult factory.
PRESSURIZED STEAM CONNECTIONS
Proper design and sizing of steam supply lines should be preformed by a qualified firm.
STEAM SUPPLY PIPING
The steam valve, actuator, wye strainer, and shut-off valve should be installed by a qualified technician.
Steam supply to the unit must be taken from the top of the supply main. Do not take from the sides or the bottom. The steam shut-off valve (supplied by others) should be installed on the supply line at the unit, followed by the wye strainer.
The steam valve and Actuator must be located as close as possible to the humidifier. Further than 6”
(15cm) away may result in lower output.

SETC OUTDOOR
INSTALLATION
SETC Outdoor units come complete with internal ventilation (cooling) for the electronics, and optional heaters for freeze protection in cold climates.
All installations must conform with local building codes. NORTEC can not accept responsibility for installation code violations.
MOUNTING
· A typical rooftop installation is shown on page 19.
· The SETC Outdoor unit comes standard with cut-outs in the base to allow for lifting by a forklift.
When lifting by this method, ensure that the forks extend across the entire base to prevent tipping or damage to the unit.
· The enclosure also comes complete with four (4) removable lifting lugs fastened to the base. All four lugs must be utilized if moving the unit in this manner. Protect the cabinet from damage from the lifting cables/chains during lifting. The lifting lugs should be removed from the base once the unit has been correctly positioned on the curb mounting.
·
The SETC Outdoor models have a zero” clearance to combustibles. However, choose the location for the humidifier to allow for side and frontal clearances for access during installation, maintenance and servicing.
· The integral base of the SETC Outdoor model is designed to mount on a curb. The curb must be built to structurally support the entire weight of the humidifier when in operation.
· Ensure that the humidifier is mounted level.
·
The pan in the bottom of all outdoor models has a pipe chase for routing of services into the humidifier from below.
· It is not necessary to make the hole in the roof the same size as the curb. The curb drawing shows the location and size of the pipe chase required. The pipe chase should be sealed when the installation is complete to ensure positive or negative pressure from the building.
· The panels of the outdoor model have louvers to provide ventilation for the electronics and air for the combustion process. Locate the unit so that
- 21 louvered panels are a minimum of 10 ft (3m) from any mechanical exhaust outlet.
·
When mounted on the curb, the lowest air intake louvers must be a minimum of 12” (30.5cm) above any surface where snow or ice could accumulate. In areas where normal snow accumulation is higher, mount the unit accordingly.
·
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of the humidifier.
PRESSURE STEAM SUPPLY
·
Steam Lines are to be routed through the pipe chase located on the floor of the unit.
·
The steam valve and actuator must be located as close as possible to the unit.
·
A wye strainer must be installed prior to the valve.
· Please refer to Actuator Installation Section.
ELECTRICAL INSTALLATION
· Power and control wiring is to be routed into the humidifier through the pipe chase in the base pan of the outdoor models located in the heat exchange area.

Typical SETC Outdoor Installation
· A field supplied NEMA rated disconnect switch must be mounted external to the SETC Outdoor unit to allow for power interruption during servicing and/or maintenance. A mounting plate, located on the front of each outdoor model above the electrical access door, is available for mounting of the disconnect switch. Two electrical conduits are provided for routing the primary wiring to the disconnect switch and then back inside the enclosure to the main power terminal strip. See Electrical Disconnect Installation
Figure for details.
FILL WATER SUPPLY LINE
· Each unit is supplied with a ½” NPT male connection to the fill valve. Refer to Installation
Figure for connection details. A minimum fill rate of 10 l/min (2.6 gpm) is required for the SE
100-675 and 17 l/min (4.5 gpm) for SE 950-1050.
Allowable pressure range is 30-80 psig.
· Always install a manual shut off within the building to allow isolation of the water to the unit.
A union must be installed on the fill line prior to the fill valve to allow for servicing.
· Heat trace fill line piping above rooftop from the pipe chase up to the fill valve.
DRAIN LINE
· SETC Outdoor units have an integrated 12” (30.5
cm) w.c. trap and vacuum break valve on the drain line.
·
Route the drain hose to a drain funnel in the building to provide an air gap before entering main building drain/sewage system.
· When the drain pump is activated, the tank drains at a rate of 18-20 l/min (7-8 gpm).
· Internal drain water tempering will ensure a maximum of 140 °F (60°C) during normal operation.
AUXILIARY DRAIN
· Standard SETC Outdoor units come with a capped ¾”NPT auxiliary drain connection at the bottom of the tank. It is recommended to install a manual shut-off valve on this connection and route to drain (provide an air gap).
· SETC Outdoor units equipped with a freeze protection package have a normally open drain valve mounted at the auxiliary drain connection and piping that terminates at the pipe chase in the base pan. This valve opens and will drain the contents of the tank in the event of a power failure. Install a manual shut off valve on this line and pipe to the drain funnel. This valve must always be left in the open position when in operation but can be closed for servicing of the unit.
· Drain pipe should be capable of withstanding
200
°F temperatures.
STEAM LINES
· The steam outlet connection is located at the back of the SETC Outdoor unit. Steam hose(s) and clamps are supplied with the unit and are intended to provide a flexible coupling outside of the unit to the building steam lines.
· SETC OUTDOOR models can develop steam pressures up to 12” (30.5 cm) w.c. to overcome duct and steam line pressures. Pressures above
12” (30.5 cm) w.c. will cause steam to exit through the drain line.
· Steam lines can be routed to an air handler on the roof or pipe chase (external to the unit) through the rooftop to enter the building.
·
All steam lines must be insulated to reduce losses.
· For steam line installation guidelines, consult the distribution system installation manual (Steam
Distributor Installation Manual Form #XX-231 and
SAM-e Short Absorption Manifold Form #XX-249
END OF SETC OUTDOOR
OPERATION
WATER MANAGEMENT
- 23 -
The SE Series is equipped with a unique float chamber water level monitoring device. Two magnetic floats measure 5 different water levels on the SETC models, and 2 different water levels on the SEP models for proper operation. The float chamber and board are located away from the boiling action to increase reading accuracy and reduce mineral build-up.
The float chamber is connected to the tank under the water level and above the water level to ensure equalization of pressure between the tank and float chamber. In addition, cooling water is introduced in
Pressure
Equalizer
Figure #9
Plumbing Connections

Vacuum Break
Main Fill to System
Dual Fill Valve
Drain Outlet
Internal Trap
Drain Pump
Aux. Drain the float chamber to reduce scale build-up. The unit also includes an internal 1” air gap and a vacuum breaker to prevent siphoning effect.
On initial start-up, the solenoid operated fill valve fills the tank. The water level reaches the backup float first and then the main float. If the backup and main floats do not read the same water level during the operation of the unit, the unit will shut down on a fault.
The unit will continue to fill to the top yellow position.
The drain pump will then be energized to drain the water level down to just below the bottom red position and then the fill valve will energize again to fill the unit to the middle green position. During this time the software is performing a test on the fill valve and drain pump.
If a demand signal is present, the unit will then begin to open the steam valve. As the unit operates, the fill valve will be pulsed to maintain the water level between the yellow and green positions. During steam production the unit will also check if the floats and drain pump are operational by activating a drain sequence every 24 hours. (adjustable to time of day)
INSPECTION AND START UP
PROCEDURE
START-UP CHECKLIST
Before the SE humidifier is operated for the first time, a complete inspection must be performed to ensure that the installation and all water, pressure steam, atmospheric steam lines, and electrical connections to the humidifier conform to the guidelines
- 24 in this manual. Complete the checklist on pages 24 &
25 before commissioning the unit.
Qualified personnel must correct any deficiencies with the installation before commissioning takes place.
Prior to starting the humidifier, it is necessary to ensure that no dirt or dust has accumulated in the electronics compartment. A build up of dust on the electronics can cause overheating and early failure of the components.
FILLING THE SYSTEM
Before the SE unit will open the steam valve, it must be filled with water and the internal controller must have completed a self-test to verify that the water fill system, level controller, and drain pump are functioning correctly.
· Close the shut-off valve in the pressure steam supply line.
· Remove any demand signal to the unit.
· Open the shut-off valve in the water supply line.
· Switch the humidifier on.
· The fill valve will energize and the tank will begin to fill (fill time is approximately 10 to 30 minutes depending on the SE model). Once the float chamber has registered low water level, the unit will perform an internal test of the fill and drain system as described in the Water Management section.
· At the completion of the test, the float chamber will indicate middle float position (green LED) and the unit will go into standby mode until a demand signal is received.
STARTING THE HUMIDIFIER
Once the tank has been filled, the humidifier is ready to be put into operation.
· Verify that the inspection checklist has been completed and all deficiencies with the installation have been corrected.
· Open the shut-off valve in the pressure steam supply line.
· Open the shut-off valve in the water supply line.
· Ensure all external controls connected to the security loop are closed.
· Verify that the building demand signal is connected to the humidifier.
· Install and secure all cabinet service doors.
· Switch the humidifier on.
· At the completion of the float test, the humidifier will begin to open the steam valve and warm up the water.
· Depending on the system demand, the actuator will open or close to control the amount of steam injected into the heat exchangers.
· The water in the tank will heat up and begin to boil, delivering steam to the distribution system.
· During the boiling sequence the water fill valve will periodically activate to replenish water that has evaporated from the tank.
· Once the humidity requirements have been satisfied (demand drops below minimum %) the steam valve will be de-energized and will be shut off.
· The humidifier will go into standby mode until the next call for humidity.
TAKING OUT OF OPERATION
If it is required that the humidifier be taken out of operation (e.g. for service or end of season shut-down), proceed as follows:
· Remove the demand signal or open the security loop, allowing the steam valve to shut off.

SCALE MANAGEMENT
The steam exchange humidifier will periodically
“blowdown” water from the tank to reduce the concentration of total dissolved solids that accumulate during long term operation.
Steam Exchange Humidifiers are shipped factory set with a blowdown of 25%. This setting ensures that scale build-up will be minimized for all water conditions.
Once the water conditions are known, the blowdown rate can be adjusted by software (SETC models) or by using dip switches on the logic control board (SEP models).
Another effective means of controlling the amount of scale in the tank is with the use of the Full Tank
Blowdown (FTBD) built into the software. When this feature is activated, the drain pump will be energized to drain the entire contents of the tank and then the tank will be refilled with fresh water, thus keeping the amount of total dissolved solids to a minimum. The feature can be programmed in the software to occur after a specific amount of operating time and can also be triggered by a signal sent to the humidifier from a building management system.
WATER QUALITY
Due to the wide range of water conditions found throughout North America it is important that the blowdown is set according to the local water conditions. By water conditions we are referring to the hardness of the water supplied to the humidifier. The hardness is measured in grains per gallon. It is also important to test for silica content. Silicates may cause foaming and contribute to scale buildup in the humidifier tank and float chamber.
If you are unaware of the hardness or silica content of your water supply, there are many “do it yourself” kits which can be purchased, or there are several companies that will perform the tests for a reasonable price. You can even contact your municipality for your water condition or order the
NORTEC water test kit.
Note: Water quality conditions resulting in component failures are not covered under
NORTEC’s standard warranty.
· Silica Test: Measured in ppm (parts per million)
Follow the directions with the kit. A high reading will
Figure #10
Site Water Test Kit P/N 1507214 decrease the performance of your system. The recommended operating range for silica is 0 ppm to
14 ppm. Note: A high silica content along with a high hardness content may increase the service intervals of the system . Consult the factory if this condition exists at the site.
· Hardness: Measured in gpg (grains per gallon).
Follow the instructions on each individually wrapped test strip and use the colour chart provided. The recommended operating range for hardness is 0 gpg to 12 gpg. Note: High hardness along with high silica may increase the service intervals of the system. Consult the factory if this condition exists at the site.
· pH: Follow the directions on the test strip bottle.
The recommended operating range for pH is 6.5
to 7.5 on the colour scale. Consult the factory if outside these parameters.
· Chlorides: Measured in ppm (parts per million).
Follow the directions on the test strip bottle. The recommended level for chlorides is not to exceed
25 ppm. High levels of chlorides will attack stainless steel. Add an in-line carbon filter that will remove up to 99% of the chlorides. Consult the factory for additional information if your water contain high levels of chlorides.
· Conductivity: Measured in micromhos. Follow the directions for the conductivity pen found inside the box. Multiply the digital reading by 1.5.
The recommended operating range for conductivity is 0 - 1500 micromhos. Consult the factory if you measure outside these parameters.

· NORTEC recommends performing a semi-annual water analysis to ensure optimal performance.
· The humidifier is intended to operate on cold potable tap water.
· DO NOT use a hot water source to supply the humidifier. Minerals will adhere more easily to surfaces and the fill valve's small flow regulating orifice could become plugged.
· Consider using a water softener. Longer operating times between tank cleaning will be reached on softened water.
· Reverse osmosis (RO) water can provide very long times before cleaning is required since it is cleaner than softened water. Deionized (DI) water may be used with all models.
· Consult your NORTEC representative for a quote on a water treatment system.
MAINTENANCE
To ensure proper performance and long operating life of the SE humidifier, a proper maintenance schedule should be followed. Since the amount and type of maintenance required is generally a result of how much the humidifier operates, all SE humidifiers monitor the amount of steam produced over time, and will indicate when service is required. All units come factory set with a service interval of 500 hours. This service interval can be adjusted through software
(SETC models) or by jumpers settings (SEP models) on the logic control board. Refer to the maintenance schedule for maintenance guidelines and intervals.
All maintenance work must be performed by experienced and trained personnel.
NOTE: Use only NORTEC original parts to replace damaged or defective components. Failure to do so may cause improper operation of the humidifier and will void warranty.
- 29 -
DRAINING THE TANK
During extended periods of inactivity such as offseason, it is advisable to drain the water from the tank.
On all models this is accomplished by switching the unit to “Drain”.
Do not remove the front or top clean out port on the tank until the unit is completely drained and cool.
The SETC model includes a pre-cleaning sequence feature. When activated (through the keypad), the unit will flush the humidifier, refill with cold water, and flush again reducing the scale accumulated at the bottom of the tank.
CLEANING THE STAINLESS STEEL TANK
& FLOAT CHAMBER
CAUTION: Water and scale may be hot enough to cause burns. Turn off humidifier and allow it to cool before cleaning.
It is recommended that the tank be cleaned at least once every season to maintain optimum operation. It may be necessary to increase the frequency of cleaning or increase the blowdown setting in areas of hard water or prolonged annual usage (see the “Blowdown Setting section of this manual).
Cleaning of the humidifier is mandatory and must be performed on a regular basis.
To reduce cleaning time, use the pre-cleaning sequence on the SETC model to help evacuate mineral debris from the unit. Check the controller operation to activate this feature.
The heat exchanger walls are usually self cleaning. The mineral build-up flakes off, due to the expansion and contraction and boiling action during on/off cycles, and settles to the bottom of the tank. The end block will have scale build-up. These surfaces must be cleaned at regular intervals.
Most cleaning will be done through the front door of the unit. Remove cabinet door on the left of the
LCD display using a Philips screwdriver. Remove the side tank port opening, by removing the 3/16” nuts (½” key or socket is needed).
Additional cleaning ports are available on the top of the SE 475/675 and SE 950/1050 models. To access these ports, remove the top cabinet panel using a Phillips screwdriver. Remove the top cleaning ports by removing the nuts.
Removal of the heat exchanger(s) is not necessary to clean the inside of the tank.
Scoop out loose scale with a small shovel such as those used for gardening. Once loose scale is removed, use a scraper such as a plastic windshield scraper to remove scale adhering to the tank or heat exchanger walls. DO NOT use a metal scraper that will scratch the stainless steel surfaces of the tank.
Once all large pieces of scale have been removed, vacuum the tank out with a shop vacuum, fill part way with water, and flush remaining sediment from the tank through the drain.
Due to the presence of polymer gaskets around the heat exchanger, do not use any harsh cleaning chemicals. Please consult NORTEC prior to using any chemicals. Once the lid has been replaced, fill the unit with water and examine for leaks.
Inspect the drain and fill lines assembly for scale build-up and if necessary, remove them from the humidifier for cleaning. If the blowdown assembly becomes blocked, scale build-up in the tank will be accelerated and damage to the humidifier could result.
The drain pump may be opened and cleaned. Consult
NORTEC for proper procedure.
Re-assemble the drain and blowdown if they were removed. Re-install tank top and side lids making sure tank cover gasket is intact. Do not over tighten nuts. If using a torque wrench do not exceed 50 in-lb ( 5 ft-lb).
Re-seal all cabinet lids.
Cleaning the float chamber is accomplished by removing the screws to access the floats and using a small brush to gently clean the scale from the floats and chamber. Ensure that floats are back in place and o-ring is properly seated before tightening screws on float chamber. Special attention must be used when removing or re-installing the float chamber. The switch board must be replaced into the same position as before cleaning and the tie-wrap must be used to hold the float chamber in position.

The customer can select the type of drain water tempering they require (depending on local plumbing codes)
The customer can select ON, OFF, or SMART.
ON – whenever the drain valve is activated through software, the fill valve will automatically activate. This is the factory default setting, but is the most wasteful of water since it will activate even if the drain water is cool.
OFF – The drain water is never tempered. This can be used where plumbing codes permit. Some process waters are very expensive, so the customer may choose to temper the drain water through other means.
SMART – The humidifier has a tank sensor that communicates the water temperature to the controller. If the water is hot during drain cycles the fill valve will be activated. This is the most “water smart” of the settings.

DRAIN NOT
WORKING
DRAIN IS BLOCKED
There are many time windows in the GS software. If, during a drain cycle, the time window for the water level to drop is exceeded, this fault is generated
-Ensure that pump is being energized
-Check for blockage in all aspects of the drain system
-Float board defective
-Consult factory

MAINTENANCE
TIME
HAS ELAPSED
Once every 24 hours (provided the unit is powered and in an operating or standby condition) the controller will test the water level detection circuit. If the test fails this fault is displayed
If the controller detects two or more float level readings, which are not expected (ex. Switch 1 and 3 ON or switch 1, 2, and 3 ON) this fault will be recorded.
The controller monitors the water level as it fills and drains. It expects to see the levels increase logically (1-2-3-4-5). If the water level increases and jumps a step (1-2-4-5) this fault will be generated. The same holds for water level decreasing.
During a keep warn cycle, if the tank temperature sensor does not open within a certain time window, this fault is generated.
-Ensure the proper operation of the fill valve and drain valve via the diagnostics screen
-Float board is defective
-Consult factory
-Miswired float board
-Defective float board
-Consult factory
-Float board defective
-Contact agent for replacement float board
-Ensure that the thank temperature sensor is connected
-Defective tank temperature switch
-Contact agent for replacement switch.
In the user menu the user sets the maintenance time. Once this time expires a warning is displayed. 72 hours later the warning changes to this fault. The maintenance time is measured in weighted operational hours.
With switch 5, #4 deactivated, this fault is enabled
-Perform tank cleaning and all other maintenance requirements outlined in the manual.
