IER Positioning & Mounting
General guidelines for positioning
IER electric steam humidifier should be positioned so that:
 Length of the steam line (or hose) is as short as possible,
 In case steam hose is used, the bend radius of 12in (300mm) is ensured
 Humidifier is easily accessible for service
CAUTION. Risk of malfunction due to vibration. Do Not mount IER electric steam
humidifier directly on ventilation duct.
CAUTION. Risk of flooding. Ensure that the local where IER electric steam humidifier
will be installed is equipped with floor drain.
In case of no floor drain is available; installation of a water leak detector is required in order to
prevent any flooding in case of abnormal operation or service.
IER electric steam humidifier should be installed in a well-ventilated and dry environment.
If local is subject to below freezing point temperature, activation of ant freezing function of the
IER electric steam humidifier is required.
For outdoor installation please contact your steamOvap representative to order and install
special outdoor optional enclosure for IER.
IER maximum ambient conditions:
Temperature: 41°F to 122°F [+5 to +50°C]

Clearances
Figure 6 – minimum clearances
Clearance guidelines
There is no minimum clearance on both side of the IER humidifier, but it is a good practice to
have a clearance of 4 to 8 in [100 to 200mm] for ease of installation and service
Allow a minimum clearance of 24in [610mm] with floor to allow for proper drain slope and
drain pipe column.
Front clearance of 30in [762mm] is required for access to the IER humidifier
Top clearance is required of 12in [304mm] for access and proper steam connection

General guidelines for Mounting
CAUTION. Risk of malfunction. IER electric steam humidifier must be levelled in X & Z
axis.
Installation on wall (without mounting bracket)
1. Verify that wall structure and strength is appropriate to support the operating weight of
the IER electric steam humidifier.
In case, the wall is not solid enough to support operating weight of IER electric steam
humidifier, install it on a floor stand (FS option is available to your steamOvap
representative).
2. Mark the wall or support according to the above holes location, and drill 4 holes to the
wall or support as per the size of anchors and/or screws.
3. Use anchors of sufficient size (at least 1/4in [6mm]). Insert those anchors and the 2 top
screws, ensure that the screw heads extends 1/4in [6mm] from the wall, so that the IER
electric steam humidifier will be able to be hung on those 2 screws.
4. With front cover removed, hung the IER electric steam humidifier onto the 2 top screws.
Insert the bottom screw through the back plate of the humidifier and into the anchors
in the wall.
Ensure that the humidifier is properly levelled.
Tighten the 3 screws. Re verify the level in the 2 direction X and Z axis.
5. Re-install the front cover to the humidifier.
6. Optional Mounting bracket (option MB) is available to your steamOvap representative
in order to ease up wall mounting process.

Installation on wall (with mounting bracket – option MB)
1. Optional Mounting bracket (option MB) is available to your steamOvap representative
in order to ease up wall mounting process.
2. Verify that wall structure and strength is appropriate to support the operating weight of
the IER electric steam humidifier.
In case, the wall is not solid enough to support operating weight of IER electric steam
humidifier, install it on a floor stand (FS option is available to your steamOvap
representative).
3. Mark the wall or support according to the above holes location, Drill holes to the wall or
support to attach the mounting bracket to the wall as per the size of anchors and/or
screws.
Distance between the 2 holes in Mounting bracket is 15in [381mm]
Figure 10 – Installation with Mounting bracket
4. Use anchors of sufficient size (at least 1/4in [6mm]). Install the mounting bracket to the
wall or support.
Ensure that the mounting bracket is properly levelled.
5. With front cover removed, hung the IER electric steam humidifier onto the mounting
bracket.
6. Install the 2 supplied screws to avoid the IER humidifier to move up from the mounting
bracket.
Installation on Floor Stand (option FS)
1. Ensure that the floor structure and strength is appropriate to support the operating
weight of the IER electric steam humidifier.
2. Attach the floor stand to the floor or structure to avoid any movement of the IER
electric steam humidifier.
You can use bolt or screws to attach this one to surrounding structure or to the floor.
3. Install Humidifier (with front cover removed) on the floor stand and secure it with
supplied bolts.
4. Re-install the front cover to the humidifier.

Installation – step 2
Water supply installation
Water supply specification & quality:
Water supply pressure: 15 to 80PSI [1 to 5bar]
Water supply temperature: 37 to 105°F [3 to 40°C]
IER electric steam humidifier can accept a wide range of water quality.
Untreated water will lead to scale deposits that will need to be regularly removed from steam
chamber.
Use of additives such as scale inhibitor or corrosion inhibitors, disinfectants or other can impair
the normal operation of the humidifier and are not allowed.
Water supply conductivity: 1 to 1500µS/cm
Water supply hardness: 0 to 16grains/gallon [0 to 15°gH][268mg CaCO3/l]
Water supply PH: 6.5 to 7.5
Water supply chloride content: 0 to 50ppm
Figure 11 – water supply connection

I N S T A L L A T I O N

Water supply connection:
1. Install a manual; shut off valve on the water main line.
2. If IER humidifier is supplied with tap water it is recommended to install a 10µ sediment
filter on the line. This filter will protect internal water fill valve from clogging.
3. A flexible braided hose is supplied for an easy and secure connection to the water
supply inlet.
This hose is equipped with 1/2in [12mm] female swivel connection at both ends.
Installation – step 3
Drain installation
Water drained specification:
Drained water maximum temperature: 120°F [60°C]
Drained water flow rate: 6.6 GPM [25 l/min]
Drain outlet dimension: IER04 to 31: (1x)1-1/4in [32mm]
IER44 & 62: (2x) 1-1/4in [32mm]
Figure 12 – water drain connection
Installation steps :
1. Ensure that an Open drain with a P-trap is installed offset from the IER humidifier.
IMPORTANT: Risk of malfunction. A minimum slope angle of 5 degree of the drain hose
or pipe and a minimum length of 24in [60cm] must be provided between the drain
outlet of the IER humidifier and the open drain inlet and P-trap.
2. If required, install a connection sleeve 1-1/4 [32mm] at the drain outlet of the IER to the
drain pipe, and secure it with the supplied 2 collars.
