Safety instructions

Please read and observe the operating instructions before fitting and

putting into operation.

Very important! The operating instructions should always be readily available and kept in

the immediate vicinity o the steam-bath generator.

All work must be done only by persons who are amiliar with the product

and are su iciently quali ied to per orm the work.

The AT 3000 D steam-bath generators have been designed and constructed

in accordance with the latest technology and the accepted sa ety

regulations. However, i misused, the steam-bath generator can present

a danger to both the user and third parties.

Apart rom these sa ety instructions, you should observe all national and

local regulations.

Proper use The AT 3000 D steam-bath generators are intended solely or indirect (via

a steam-distribution pipe in a ventilation duct) or direct (with either

a separate or a steam-bath generator-mounted an) humidi ication. Used in

any other way, or in a way that goes above and beyond the one described

above, is contrary to its intended usage. The manu acturer/supplier cannot

be held responsible or any damage resulting there rom. The user shall

bear the risk.

Alterations to the steam-bath generator Without NORDMANN’s written approval, no alterations may be made to

the steam-bath generator itsel , the components or the accessories.

The use o non-original spare parts may lead to our re usal to accept res-

ponsibility or any damage arising there rom.

Safety instructions Whenever you see either o these signs, particular care must be taken.

1.2 Fitting the steam-bath generator

All installation ork must be performed by trained personnel.

The customer himself is responsible for verifying their qualifications.

When itting the steam-bath generator, use only the material supplied

with the unit and observe the various minimum distances that have been

stipulated.

To open the steam-bath generator, turn the screw, using the correct

screwdriver, in an anti-clockwise direction; the door to the water

componentry or the electrics then opens. To close, simply push back into

place (no screwing down is necessary).

Positioning the steam-bath generator Ensure that there is su icient room to per orm servicing and maintenance

work, and that the unit is easily accessible. To acilitate such work, mount

the unit at eye level.

We recommend that you it the steam-bath generator as near as possible

to the steam-bath cabin. The highest degree o e iciency is attained when

the steam-bath generator is linked to the shortest possible steam hose.

1.3 Laying the steam hose

The steam hose should be kept as short as possible. It should not be pos-

sible to block or obstruct the steam supply lines in any way. Furthermore,

they must be protected rom outside inter erence (e.g. de ormities,

kinking etc.).

A ter the hose has been laid, it is advisable to re-check everything when

the hose is warm.

It is equally important to avoid condensation pockets in the hose. Any

curves should have as large a radius as possible.

Installation material I a hose is used or the steam line, it must be the original one supplied

by NORDMANN. I other hoses are utilized, NORDMANN cannot be held

responsible or any damage that may occur.

When laying the steam hose in pipes, cable ducts etc., you must veri y their

resistance to high temperature (min. 100 °C). All insulation material must

also be checked or its resistance to high temperature.

I the steam line installed is o copper, small radii should be avoided

wherever possible. Every bend causes an additional resistance. A steam line

o copper must have the same diameter as the hose.

I the steam lines are long with a lot o bends, water may be continuously

orced out o the steam cylinder, which impairs per ormance.

Correctly installed

1.4 Perfume injection

The per ume should be injected in a vertical steam pipe as near as possible

to the cabin. A T-piece should be used there ore.

2.1 Quality of the ater

NORDMANN steam-bath generators use ordinary tap water or the

production o clean steam. The electrical conductivity should be between

125 and 1250 microsiemens per cm.

The hardness o water is measured in accordance with the international

unit millimol, calcium and magnesium ions per litre (mmol/l), previously

the degree o German hardness (DH):

So t water: up to 1.3 mmol/l; up to 7°DH

Fairly hard water: 1.3 to 2.5 mmol/l; 7 to 14°DH

Hard water: 2.5 to 3.8 mmol/l; 14 to 21°DH

Very hard water: over 3.8 mmol/l; over 21°DH

Other international units: 1°DH = 1.79° (French hardness)

1°DH = 1.25° (English hardness)

1°DH = 1.05° (American hardness)

1°DH = 10 mg/l CaO

1°DH = 17.9 mg/l CaCO3(ppm)

NORDMANN’s electrode steam-bath generators allow you to use water

ranging rom so t to very hard, without the need or prior treatment.

However, or airly hard water and above, we recommend the use o

the SC-System (NORDMANN’s sel -cleaning system), since this greatly

reduces the amount o maintenance required or the cylinder.

2.2 Water intake and drainage

All installation ork must be performed by trained personnel.

The customer himself is responsible for verifying their qualifications.

Please observe local regulations concerning the connection o appliances

to the pressure and drainage systems.

The steam-bath generators are designed to operate on ordinary tap water.

I you intend using treated or de-mineralized water, consult your

NORDMANN representative be orehand.

Connecting to the cold- ater supply, ith stop cock

Where the water pressure is between 1 and 10 bar (0.1 to 1 MPa),

the unit can be connected directly to the water supply. I it is over 10 bar

(1 MPa), connection must be via a pressure-reduction valve

(set to 4–6 bar, = 0.4–0.6 MPa).

2. Water connections

In any case, the water eed pipes that you have laid

must be lushed thoroughly be ore connecting

them to the steam-bath generator. You should use

copper piping only.

Note that the drainage acility should provide the

possibility o per orming cleaning and maintenance.

The drainage pipe should have a decline to the

drainage system o at least 5%.

A ine ilter should be itted at the water intake

to the steam-bath generator; this prevents the rapid

build-up o impediments in the inlet ilter o the

inlet valve.

3.1 Safety instructions

All ork pertaining to the electrical installation must be carried out

by qualified personnel only. The customer is responsible for verifying the

qualifications of the technicians concerned.

Be ore per orming any electrical work, all power to the steam-bath

generator must be disconnected.

Please observe local regulations concerning electrical installations.

The installation must be itted with a device which disconnects the unit

(with a contact opening o at least 3 mm) on all phases rom the mains

power supply.

NORDMANN steam-bath generators are designed to be connected

to the earth lead and are categorized as belonging to Protection class 1

or electrical equipment.

The connection details are provided in the wiring diagrams or each type

o unit. Each unit is supplied with the appropriate wiring diagram.

External fuses per phase (A):

3.2 Control voltage

The standard control voltage is 220–240 V. A use (F1) 6 A and a spare use

located in the terminals o the use holder, are incorporated in the steam-

bath generator. The electronics and the accessories have a 24 V power

supply which is protected by a use (F2) 1.6 A. A spare use is situated in

the terminals o the use holder.

N.B.: When performing cleaning and maintenance ork on the unit,

all po er to the steam-bath generator, including the control voltage,

must be disconnected.

The cross-section o the electrical wires and the minimum use size should

be chosen in accordance with the connection requirements (c . technical

speci ications) o the type o steam-bath generator employed. The electric

supply cables must be connected to the unit’s terminals correctly.

We recommend that the screw terminals be re-tightened a ter a ew days.
