IER Positioning & Mounting
General guidelines for positioning
IER electric steam humidifier should be posioned 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 malfuncon due to vibraon. Do Not mount IER electric steam
humidifier directly on venlaon 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; installaon of a water leak detector is required in
order to prevent any flooding in case of abnormal operaon or service.
IER steam humidifier should be installed in a well-venlated and dry environment.
If local is subject to below freezing point temperature, acvaon of ant freezing funcon of the
IER steam humidifier is required.
For outdoor installaon please contact your steamOvap representave to order and install special
RT outdoor enclosure for IER.
IER maximum ambient condions:
Temperature: 41°F to 113°F [+5 to +45°C]
Relave Humidity: 90%RH max (non condensing)

Clearance guidelines
There is no minimum clearance on both side of the IER humidifier, however it is a good pracce to
allow a clearance of 4 to 8 in [100 to 200mm] for ease of installaon 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 ease of steam line connecon.

Front clearance of 80in [2000mm] is required for steam absorpon.
A 24in [600mm] top clearance above SB – space blower is required for access and for steam
absorpon to avoid any condensing on the ceiling.

General guidelines for Mounting
CAUTION. Risk of malfuncon. IER electric steam humidifier must be levelled
in X & Z axis.
Installaon on wall (without mounng bracket)
1. Verify that wall structure and strength is appropriate to support the operang weight of
the IER electric steam humidifier.
In case, the wall is not solid enough to support operang weight of IER electric steam
humidifier, install humidifier on the floor stand (FS opon is available to your steamOvap
representave).
2. Mark the wall or support according to the above holes locaon, 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 boom 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 direcon X and Z axis.
5. Re-install the front cover to the humidifier.
6. Oponal Mounng bracket (opon MB) is available to your steamOvap representave in
order to ease up wall mounng process.

I N S T A L L A T I O N
Installaon on wall (with mounng bracket – opon MB)
1. Oponal Mounng bracket (opon MB) is available to your steamOvap representave in
order to ease up wall mounng process.
2. Verify that wall structure and strength is appropriate to support the operang weight of
the IER electric steam humidifier.
In case, the wall is not solid enough to support operang weight of IER electric steam
humidifier, install it on a floor stand (FS opon is available to your steamOvap
representave).
3. Mark the wall or support according to the mounng bracket holes locaon, Drill holes to
the wall or support to aach the bracket to the wall as per the size of anchors and/or
screws.
Distance between the 2 holes in mounng bracket is 15in [381mm]

4. Use anchors of sufficient size (at least 1/4in [6mm]). Install the mounng bracket to the
wall or support.
Ensure that the mounng bracket is properly levelled.
5. With front cover removed, hung the IER electric steam humidifier onto the mounng
bracket.
6. Install the 2 supplied screws to avoid the IER humidifier to move up from the mounng
bracket.
7. Re-install the front cover to the humidifier.
Installaon on Floor Stand (opon FS)
1. Ensure that the floor structure and strength is appropriate to support the operang weight
of the IER electric steam humidifier.
2. Aach 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 aach 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.

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 addives such as scale inhibitor or corrosion inhibitors, disinfectants or other can impair
the normal operaon of the humidifier and are not allowed.
Water supply conducvity: 1 to 1500µS/cm
Water supply hardness: 0 to 16grains/gallon [0 to 15°gH][268mg CaCO3/l]

Water supply connection:
1. Install a manual shut off valve (supplied by others) on the water main line.
2. If IER humidifier is supplied with tap water it is recommended to install a 10µ sediment
filter (supplied by others) on the line.
Alternavely steamOvap can provide a 2 stages pre-filter 5 + 1μ PP filter as extra
protecon and filtraon (model WF-51).
3. A flexible braided hose is supplied for an easy and secure connecon to the humidifier
water supply inlet.
This flexible braided hose will ease of the installaon and act as shock absorber and
protecon for the internal water fill valve.

Risk of overflow.
✔A minimum slope angle of 5 degree of the drain hose or pipe and a minimum length of
24in [60cm] must be provided between IER’s module drain outlet and building’s open
drain inlet.
✔Do not reduce diameter of the drain line. Drain line between IER’s module drain outlet and
building’s open drain inlet must be 1-1/4in [DN32] diameter minimum
✔18in [45cm] minimum vercal run before P trap or obstrucon must be provided.
✔Do not install P-trap directly (or any other obstrucon) at the IER’s drain outlet.
Installation steps:
Important note: There is one drain outlet per IER module.
So there are 2 drain outlets for models IER24, IER34, IER44 and IER62.
1. Ensure that an Open drain with a P-trap is installed offset from the IER humidifier.
Main building drain diameter should be
◦1-1/2in [DN40] for single module IER
◦2in [DN50] for two modules IER (model IER24, IER34, IER44 or IER62)
in case such drain diameter is not available (i.e. in old building), increase the diameter or
height of vercal run before to enter the main building drain.
Refer to informaon of full cylinder volume above for volume calculaon.
2. Drain line can be made either with flexible hose or hard pipe.
Supplied connecon sleeve 1-1/4 [32mm] allow for ease of connecon to IER’s module
drain outlet to the drain pipe, and secure it with the supplied 2 collars.
✔Drain line must be slopped - 5° minimum slope from IER module to building’s open
drain inlet.
✔Do not reduce 1-1/4in [DN32] diameter at any point of the drain line
✔Avoid short 90° elbow
✔a minimum 18in [45cm] vercal run pipe must be provided upstream any P-trap or any
other obstrucon.
