2 For your safety

General

Every person working with the Condair EL must have read and understood the operation manual of the

Condair EL before carrying out any work.

Knowing and understanding the contents of the operation manual is a basic requirement for protecting

personnel against any kind of danger, to prevent faulty operation, and to operate the Condair EL safely

and correctly.

All icons, signs and markings applied to the components of the Condair EL must be observed and kept

in readable state.

Qualicationofpersonnel

All work described in this operation manual may only be carried out by specialists who are well

trainedandadequatelyqualiedandareauthorizedbythecustomer.

For safety and warranty reasons any action beyond the scope of this manual must be carried out only

by qualied personnel authorised by the manufacturer.

It is assumed that all persons working with the Condair EL are familiar and comply with the appropriate

regulations on work safety and the prevention of accidents.

The Condair EL steam humidier may not be used by persons (including children) with reduced physical,

sensory or mental abilities or persons with lacking experience and/or knowledge, unless they are super-

vised by a person responsible for their safety or they received instructions on how to operate the system.

Children must be supervised to make sure that they do not play with the Condair EL steam humidier.

Intended use

The Condair EL steam humidier is intended exclusively for airhumidicationviaasteamdistribu-

tororblowerpackapprovedbyCondairwithinspeciedoperatingconditions. Any other type of

application, without the written consent of Condair, is considered as not conforming with the intended

purpose and may lead to dangerous operation and will void any warranty.

Operation of the equipment in the intended manner requires that all the information contained in this

operation manual are observed (in particular the safety instructions).

8For your safety

DangerthatmayarisefromtheCondairELsteamhumidier

DANGER!

Dangerofelectrichazard!

The Condair EL is mains powered. Live parts may be exposed when the door panels of the

steamhumidierareromoved.Touchinglivepartsmaycausesevereinjuryordangertolife.

Prevention: Before carrying out any work set the Condair EL out of operation as described in chapter

4.5 (switch off the unit, disconnect it from the mains and stop the water supply) and secure the unit

against inadvertent power-up.

WARNING!

Hot water vapour - Danger of scalding!

TheCondairELproduceshotwatervapour.Thereisdangerofscaldingwhencomingincontact

with hot water vapour.

Prevention: Do not carry out any work on the steam system during operation (steam lines, steam

distributor, blower pack, etc.). If the steam system is leaky set the Condair EL immediately out of

operation as described in chapter 4.5. Correctly seal the steam system before putting the unit into

operation again.

WARNING!

Danger of burning!

During operation the components of the steam system (steam cylinder, steam distributor, etc.)

get very hot (up to 100 °C). There is danger of burning when touching the hot components.

Prevention: Before carrying out any work on the steam system set the Condair EL out of operation as

described in chapter 4.5, then wait until the components have cooled down sufciently thus preventing

danger of burning.

Preventing unsafe operation

If it is suspected that safe operation is no longer possible, the Condair EL should immediately be

shut down and secured against accidental power-up according to chapter4.5. This can be the case

under the following circumstances:

– if the Condair EL is damaged

– if the electrical installations are damaged

– if the Condair EL is no longer operating correctly

– if connections and/or piping are not sealed

All persons working with the Condair EL must report any alterations to the unit that may affect safety to

the owner without delay.

Prohibitedmodicationstotheunit

Nomodicationsmustbeundertaken on the Condair EL without the express written consent of Condair.

For the replacement of defective components use exclusively original accessories and spare parts

available from your Condair representative.

10 Product Overview

3.2 Functional description

The Condair EL steam humidier is an atmospheric steam generator. It operates on the electrode heating

principle and is designed for direct room air humidication (with blower pack) and indirect humidication

(with steam distributor) in venti lating and air-conditioning systems.

Water supply

The water is supplied via a lter valve (accessory "Z261") to the steam humidier. It reaches the steam

cylinder via the inlet valve and the open ll cup.

Steam generation

Any time steam is requested, the electrodes are supplied with voltage via the main contactor. Simulta-

neously, the inlet valve opens and the water enters the steam cylinder from the bottom via the open ll

cup and lling hose. As soon as the electrodes come in contact with the water, current begins to ow

between the electrodes, generating heat and increasing the water evaporation rate. The more of the

electrode surface area that is exposed to conductive water, the higher the current consumption and thus

steam production.

Upon reaching the requested steam capacity, the inlet valve closes. If the steam generation decreases

below a certain percentage of the required capacity, due to lowering of the water level (e.g. because of

the evaporation process or drainage), the inlet valve opens until the required capacity is available again.

If the required steam capacity is lower than the actual output, the inlet valve is closed until the desired

capacity is achieved by lowering of the water level (evaporation process).

Level monitoring

A sensor, provided in the steam cylinder, detects when the cylinder water level is at the maximum. When

the sensor comes in contact with water, the inlet valve will close after a short delay.

Drainage

As a result of the evaporation and rell process, the conductivity of the water increases due to an escalat-

ing mineral concentration. Eventually, an inadmissibly high current consumption would take place if this

concentration process were permitted to continue. To prevent this concentration from reaching a value,

unsuitably high for the operation, a certain amount of water is perio dically drained from the cylinder and

replaced by fresh water.

Control

The steam production can be controlled via the internal or an external continuous Proportional (P)/

Proportional-Integral (PI) controller or with an On/Off control via an external humidistat.
