a

The Humidifier ELMC can run with 3 different water
qualities:

TAP WATER

The water TH should be between 0 and 40° French
grade for a conductivity between 1000 and 350 µ/s.

For the maintenance frequency of the cylinder see
the maintenance curve. The ELMC incorporates a
time counter (hours, steam KG...) and shows
maintenance messages when appropriate.

SOFTENED WATER

The ElectroVap MC humidifier may be used with
softened water : 0°<TH< 2°.
IMPORTANT: Softeners must be programmed
correctly. Failure to programme the softener
correctly may lead to excessive salt concentration in
the steam cylinder. For assistance contact the
Softener Manufacturer. The use of duplex softeners
is recommended.

Reverse Osmosis and

Steam output

Installation

Use steam hose from our supply only.

This steam hose is able to withstand 100°C.

The humidifier should be located within 3m of the
steam distribution pipes if hose is to be used. If
the humidifier is located higher than 3m from the
steam distribution pipe/s, insulated copper tube
should be used.
The maximum recommendable length for steam
pipe, including elbows, is 6m.

IMPORTANT:
1 elbow = 1 m equivalent length of steam pipe.
There should be NO HORIZONTAL RUNS of
steam hose or pipework. All steam pipework
must fall either back toward the unit or toward the
steam distribution pipe at an angle of 15°C to
prevent condensation being trapped.

The drain operates under gravity only. Ensure
drain pipework has a pitch of at least 15°C to
allow the unit to drain efficiently.

The Devatec recommended steam hoses should
be used for connecting the humidifier to the drain
network. Regular replacement is recommended.

The temperature of the water discharged from the
humidifier is between 60°C and 100°C. Ensure the
pipe work used is capable of withstanding such
temperatures.

The discharge hose must be free from any obstacle.

It is recommended that each steam cylinder has its
own drain pipe and tundish arrangements. This will
permit fast and easy identification of a fault within a
cylinder.

The discharged water should be offset from the
underside of the unit as shown. This will prevent
any steam and/or condensation from getting into
the cabinet.

The ventilation units may be top or remote
mounted. In remote mounting applications, the
distance between the ventilation unit and an
opposite wall should be no less than 3 m. Where
the output of an individual cylinder exceeds the
the capacity of a single ventilation unit, two units
should be used equally distant from the ELMC
humidifier (X). (X1=X2).

T = is suitable tee, available from supplier (see
option list). Connection of room ventilation

Steam pipe positioning

Installation

Positioning the recommended template
profile for cut-out in DUCT/AHU (at the end
of the brochure)

A minimum distance of 300mm between the
center of the steam distribution pipe and the top
of the duct should be allowed. Where the
distribution pipe is installed at an angle of
between 30°C and 45°C, this may be reducted
to 150mm.

d: Minimum distance between the steam
distribution pipe and any obstacle in the duct
(filter, bend, constriction. etc) should as far as
possible, be no less than 2000 mm.

In the case where a steam pipe is installed after a
bend, it should be positioned in the main air flow.

In vertical ducts where air flow is upward or
downwards, the steam distribution pipe should be
mounted at an angle of 15°C from vertical.

Calculation of the evaporation distance

Installation

In order to determine the evaporation distance, the
enclosed calculation table can be used with :

RH1 = relative humidity of the air before humidification

Before or after ventilation area

After expansion or before constriction

Vapor trail = 0.5 D

Before control sensor allow

3 – 5D for evaporation

RH2 = Relative humidity of the air after humidfication in %

RH Max = maximum difference between RH1 & RH2

HOW TO USE THE CALCULATION
TABLE

Determine the difference between the relative humidity
after the humidification (RH2) and the relative humidity
(RH1) before humidification. The intersection between the
deducted maximum RH value and RH2 gives the
evaporation distance in meters (or in inches).

The tables show the D distance (in meter/inches) that
should be between the steam pipe and the first obstacle
(s.a. pipe positioning drawings on the lelft hand side).

If the require distance cannot be obtained on site, it is
possible to install two pipes in parallel to have a better
steam distribution.

NOTA : the evaporation distance shown in the

enclosed tables are for temperature between 10°C (50°F)
and 25°C (77°F) and for an air velocity of 2.5 m/s (8.20
ft/s).

If accurate values cannot be reached, a distance of 2 m.
(78 ft) should be considered as a minimum distance
between pipes & obstruction.

Optional temperature control sys

tem

INSTALLATION

For sanitation : this system holds the water in the cylinder at a temperature of 65°C

(150°F) to prevent bacteria or mold from forming in the cylinder if there is no humidity

demand.

For fast boiling : when there is a demand for humidity, the water boils more quickly than

with cold water. This produces a faster response to the humidistat and more accurate

control.

For freeze protection : can prevent freeze-up if the humidifier is subject to cold

environments. (Additional protection required for the water feed and drain lines). The

optional temperature control system overrides the automatic pre-set draining time where

the cylinder(s) is (are) drained after x hours of stop.

Note : the humidifier temperature must be switched on for this system to operate.

Set supplied in parts :
T° sensor, X4 connector, stainless steel tube x
Ø40mm or Ø25mm (according to ELMC model) &
clamps.

300mm

The electrical wiring of the temperature sensor is
made on terminals n° 15 & 16 of the X4 connector of
the main board ref : 500100/03.

For boards with reference inferior to 1_22963
(programm : V2-11-), a 5,11 K.ohm resistance should
be put between terminal 15 & 17 of the X4 connector.

The ELMC steam humidifiers can be run as a master and slave system. You have to connect the regulator
signal on (Connector x5 terminals 18-19-20) and servo control (terminals 1-2) to a master unit ( ex: the closer to
the regulation system ) and to send back this wiring on the other units (slaves).

IMPORTANT:

All the units must have the remote circuit board built-in.

WITH A REGULATION 0 – 10 V

With a 0-10V signal, the number of the units is limited by the regulator power only.

Cylinder maintenance

Maintenance

The ElectroVap ELMC is delivered with disposable cylinder(s) in standard which
can be replaced by cleanable ones, however, without any modification, according
to the choice of the user. Drain the steam cylinder using the manual drain key.
When the cylinder is fully drained switch off the unit and isolate the power. The

steam cylinder may be very hot. Allow it to cool down before removing.

Remove front panel from the humidifier to access the cylinder compartment.
Disconnect the steam hose from the top of the steam cylinder. Remove power and
high water level electrodes from top of the steam cylinder.

Lift the cylinder upwards until it is clear of the drain valve. Ensure that the gasket
remains in the drain valves. The disposable cylinder will be merely replaced by
new ones.

Cleanable cylinder:

Mark the edge of the cylinder halves so the can be matched up when
reassembled.

Note:
The constant heating and cooling of the cylinder may cause distortion.
Consequently the cylinder halves must be assembled in the same relative position.
Remove nuts and bolts around the centre of the cylinder. Open up cylinder. It is
important that the strainer in the bottom half of the cylinder is also cleaned.

Clean the electrodes by scraping off the mineral deposits. Alternatively, this can be
done using weak descaling solution. Rinse the electrodes and the body of the
cylinder. IT IS IMPORTANT TO AVOID DISTORTION THE CYLINDER IN
ATTEMPTING TO REMOVE ANY MINERAL DEPOSITS FROM IT. Relocate the
strainer in the cylinder base. Replace the cylinder gasket on the rim of the bottom
half of the cylinder and then locate the upper half of the cylinder on the gasket,
TAKING CARE THAT THE MARKS ARE ALIGNED. Refit the nuts and bolts.
Clean the O-ring on the drain valve and if necessary, change it. (every 2-3 cylinder
cleanings). Locate the steam outlet of the cylinder in the retaining clip.Position the
base of the cylinder over the drain valve and push downwards. Reconnect the
power cables.

General:

The humidifier requires regular maintenance to ensure efficient operation and to
prevent breakdown.
The exact maintenance frequency is variable and will depend on water quality,
hours run and level of demand for humidification.
New installations should be inspected / serviced every 2 to 4 weeks. This may be
too frequent, but it will enable a suitable maintenance routine to be established.

Routine inspection:

The following is a guide to work that should be undertaken in a routine inspection.

1 - Inspect water and steam installation for leaks and damage.
2 - Inspect electrical installation for any loose cables and or damages.

Components.
3 - Inspect the steam cylinder for scale deposits. If the scale in the cylinder is
half way up the stainer in the lower half of the cylinder it should be
replaced / cleaned (see changing steam cylinder).
4 - Inspect the inlet valve. The drain valve may become blocked with scale
from the steam cylinder. This will cause water to continually run to drain.
