WARNING: For Modulating Humidifier, maintain the maximum power of the
electrical installations according to the information in Table 4 - Output and Power
Consumption.
Do not consider a possible reduction of steam output due to modulation.

Mechanical Installation
General Recommendations
WARNING: Risk of electric shock. Disconnect the appliance from electric supply before
commencing installation.
Note: Mechanical installation must conform to local codes and regulations.
Location
WARNING: The SKE4 series is designed for indoor installation only.
For outdoor installation, the SKE4 must be installed using a Neptronic weather proof
enclosure (see Positioning and Mounting - Weather Proof Enclosure Unit on page 17).
Failure to follow these guidelines will void the warranty.
Consider the following points before deciding the location for the SKE4 Steam Humidifier:
Plan a location that is easy to access and permits an easy inspection and servicing of the
humidifier.
Do not install the humidifier where failure of the appliance could cause damage to the
building structure or to other expensive equipment.
Ensure that the location is well ventilated and that the ambient temperature is less than
30°C.
Consider the total steam line length between the humidifier and the steam distributor
based on the steam line material type:
oFor flexible steam hose, total steam line must not exceed 5 meters. For longer
distances, use insulated hard piping.
oFor insulated hard piping, the total steam line is determined by the humidifier
capacity: 0.67 m for each kg/hr capacity of the humidifier, with a maximum of 15 m.
For longer steam line runs, consult factory.

SKE4-E Steam Humidifier
Installation Instructions and User Manual
www.neptronic.com
Page | - 12 -
Positioning
Ensure that the front panel, the left side (plumbing compartment) and the right side
(electrical compartment) are accessible in order to permit servicing.
Leave a clearance of at least 1.2 m to the front panel and 0.3 m on the left and right sides
of the humidifier.
Leave a clearance of at least 0.5 m on top of the humidifier.
For models SKE4-E05 to E80:
oMount the humidifier at a minimum height of 0.6 m above floor level.
oLeave a clearance of at least 0.25 m under the humidifier for installation of water
supply, drain piping and electrical connections.
For models SKE4-E90 to E120:
oThese models are designed to be installed directly on the floor. Adjustable legs
are provided in order to ensure proper level.
oProvide a level, solid foundation and ensure that the floor beneath the humidifier
is water proof to withstand any water spillage during servicing or in the event of a
problem.

Wall Mounting
CAUTION: Risk of malfunction. The humidifier must be placed at an equal level.
CAUTION: Risk of overheating. Do not block the ventilation openings located on
the cabinet.
Before proceeding, check the strength of the chosen support or wall (brick, concrete, stud partition wall)
on which the humidifier will be mounted. See the Dimensions and Weight section (page 7) to know the
weight of the unit.

To wall mount the humidifier, perform the following steps:
1. Place the top bracket (supplied) on the support or wall as per the dimensions specified in
Table 5 - Positioning Lines of Mounting Brackets.
2. Drill 4 screws (not supplied) into the slotted holes of the top bracket, to secure the bracket
to the support or wall.
3. Place the bottom bracket (supplied) on the support or wall as per the dimensions
specified in Table 5 - Positioning Lines of Mounting Brackets.
4. Drill 4 screws (not supplied) into the slotted holes of the bottom bracket, to secure the
bracket to the support or wall.

Positioning - Humidifier with SDU
The SDU must be installed in an environment where the air is relatively clean. This will
prevent the blower from getting clogged with dust.
The humidifier must be mounted such that the SDU fan section is at least 2 m above the
floor.
Allocate a minimum clearance of 0.45 m from the ceiling to avoid ceiling and wall
condensation.
If additional ventilation is not present, ensure that the fan has a clearance of at least 1.35
m from the ceiling. Proper ventilation must be observed to avoid ceiling and wall
condensation.

Steam Dispersion System
Steam Dispersion System Selection
In order to prevent the accumulation of condensation in air ducts, Neptronic has designed four basic
configurations of steam distribution systems to provide the most economical solution for any particular
application.
Steam Absorption Manifold (S.A.M.) Horizontal Duct
The S.A.M. system is suitable for installations where absorption distances are short, less than 1500
mm, and/or low duct temperatures are in effect.
Illustration 13 - Steam Absorption Manifold (S.A.M) Horizontal Duct
Steam Absorption Manifold (S.A.M.E2) Horizontal Duct
The S.A.M.E2 system is suitable for installations where absorption distances are short, less than 1500
mm, and/or low duct temperatures are in effect. S.A.M.E2 are used in applications with restricted duct
dimensions.

Steam Absorption Manifold (S.A.M. or S.A.M.E2) Vertical Duct
S.A.M. or S.A.M.E2 systems for vertical ducts are used when the absorption distances are normal and
the requirement is for an economical and efficient solution.
Illustration 15 - Steam Absorption Manifold (S.A.M. or S.A.M.E2) Vertical Duct
Multi-Steam System
The Multi-Steam system is used in critical locations in air handling systems, particularly where
absorption distances are very short, less than 900 mm, or where low air duct temperatures are present.
The Multi-Steam is custom made to the dimensions of the duct or AHU.
Instructions to install the Multi-Steam system are described in a specific installation instructions
manual enclosed with the Multi-Steam system.
