3.4 Functional description

The Condair CP3 D is a pressureless steam generator that utilizes an electrode heating. The Condair
CP3 D is designed for steam generation in a steam bath.

Steam generation

Any time steam is requested, the electrodes are supplied with voltage via main contactor. Simulta­neously, the inlet valve opens and water enters the steam cylinder from the bottom via water cup
and supply line. As soon as the electrodes come in contact with the water, current begins to flow
between the electrodes, eventually heating and evaporating the water. The more the electrode surface
is exposed to water, the higher is the current consumption and thus the steam capacity.
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).

11

Level monitoring

A sensor provided in the steam cylinder cover detects when the water level gets too high. The mo­ment the sensor comes in contact with water, the inlet valve closes.

Drainage

As a result of the evaporation process, the conductivity of the water increases due to an escalating
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 periodically drained from the
cylinder and replaced by fresh water.

Control

The steam production is controlled steplessly (continuous control) by the KTY temperature sensor
supplied (or an 0-10V temperature sensor) and the integrated continuous controller.

Below a minimum controllable steam output a two-point control (On/Off) is used.

The installation site of the steam generator depends largely on the location of the steam distributor
(see chapter 5.4). To ensure proper functioning of the steam generator and to obtain an optimal
efficiency, the following points must be considered and observed when choosing the location for
the steam generator:

– Install the steam generator so that the

length of the steam hose is kept as short as possible
(max. 4 m) and that the minimum bend radius (R= 300 mm) and up-slope (20 %) or down-
slope (5 %) of the steam hose is observed (see chapter 5.4.5).

– The steam generators Condair CP3 D are designed for wall-mounting. Make sure that the construc

tion (wall, pillar, floor-mounted console, etc.) to which the steam generators are to be mounted,

max. 4 m) while observing the minimum
bend radius of 300 mm. Important! Allowance must be made for a pressure loss of 10 mm
water column (approx. 100 Pa) per meter steam hose.
Note: If your particular installation exceeds the maximum steam hose length of 4 m contact

your Condair representative. In any case, steam hoses longer than 4 m must be insulated in
their entire length.

– Reductions in the cross section such as kinks should be avoided throughout the entire length of

the hose. The installation of a stop cock in the steam hose is not permissible.

– Steam hoses must be prevented from sagging (condensate pockets); if necessary, support with

pipe clamps, trough, or wall brackets, or install a condensate drain in the steam hose.

–

Important! When deciding on the length and layout of the hose, it should be noted that the
steam hose may become somewhat shorter with progressive ageing.

Securing the hose

The steam hose must be secured to the steam distribution pipe and the steam outlet of the steam
generator by means of hose clamps.

Caution! Do not overtighten the hose clamp on the steam connector of the steam generator.

Steam line with fixed piping

For steam lines with fixed piping, the same instructions apply to the laying of the piping as already
described. The following additional notes should be observed:

27

– The

– Use exclusively Cu pipe or stainless steel (min. DIN 1.4301).

– To minimize the condensate formation (=loss), the steam pipes must be insulated.

– The minimum bend radius for solid pipes is 4-5 x internal diameter.

The steam generator carries out a system test, during which all the
LEDs light up and the opposite display is shown.

If a failure occurs on the system test, a corresponding error message
is shown in the display.

After the system test the operating display is shown.
Note: The contents of the operating display and the setting of the keys
depend on the actual operating status and on the configuration of the
Condair CP3 D and can differ from the opposite display.

Depending on the selected operating mode of the Condair CP3 D,
the steam generator must manually be started via the Start/Stop
button of the display and control unit or via an external Start/Stop
button or the operation runs time-controlled via the day timer or the
week timer. As soon as the steam generator is started, the heating
current is switched on. The inlet valve opens (slight delay) and the

steam cylinder fills with water. As soon as the submerged electrodes
heat the water up the green LED lights up and after a few minutes
(approx. 5–10 minutes, depending on the conductivity of the water)
steam is produced and the steam bath cabin is heated up. As soon

as the set temperature in the steam bath cabin is achieved, the light
is switched on and the bath phase starts. During the bath phase the
fragrance pump (if available) is controlled in accordance with the se­lected operating mode and the fan (or the flap actuator) is controlled
in accordance with the set temperature and the actual temperature
in the steam bath cabin.

Note: If the Condair CP3 D is operated with water of low conductivity it may happen that the
maximum steam capacity is not reached in the first few hours of operation. This is normal. As
soon as the conductivity has reached a sufficient level (due to the vaporisation process) the steam
generator will reach the maximum steam capacity.

1. Use a screwdriver to undo the two screws fixing the front panel to the unit, then remove the
front panel.

2.

Units with steam hose connector in housing top: release the two hose clamps on the rubber
sleeve using a screwdriver, then detach the rubber sleeve from the connection in the unit cover
and from the steam outlet connection of the steam cylinder.

Units without steam hose connector in housing top (not shown): release the hose clamp
on the steam hose using a screwdriver, then detach the steam hose from the steam outlet con­nection of the steam cylinder.

3 4

3. Remove all plugs from the electrodes and from the level sensor.

4. Loosen the two screws of the steam cylinder fixing device by a few turns, then push the fixing
device upwards until it comes loose and remove it.

52

5. Carefully lift steam cylinder away from the cylinder receptacle, then remove it to the front.

CAUTION!

Put steam cylinder down carefully to avoid damage to the lower connection
piece!

Installation of the steam cylinder follows the reverse sequence. Observe the following:

– Before installing the steam cylinder in the unit, check the O-ring of the cylinder receptacle for

damage and replace if necessary.

– Moisten the O-ring of the cylinder receptacle with water (do not use grease or oil), then insert

steam cylinder into the receptacle and push it down to the stop.

– Attach the electrode plugs and the level sensor plug to the respective electrode and sensor con

nections according to the following table.

cylinder.

2. Release clamp clips of the cylinder cover and raise cover.

3. Remove carefully electrodes by lifting upwards.

4. Remove O-rings from the electrodes.
Note: Intact O-rings can be reused.

The assembly of the cleanable steam cylinder follows the reverse sequence. Observe the following:

– Before assembling the steam cylinder, check the O-ring in the steam cylinder cover and the

O-rings on the electrodes for damage, and replace if necessary. Make sure to relocate O-rings
correctly.

– Insert electrodes into steam cylinder cover and push them upwards until the snap fasteners engage.

– Place the cylinder cover (with mounted O-ring) in the correct position (align the two cams on the

steam cylinder body with the corresponding grooves in the cylinder cover) on the cylinder body
and secure cover with the fastening clips.

7.3.3 Removal and installation of the water cup and the water hoses

To improve accessibility for removing the water cup and the water hoses we recommend to remove
the steam cylinder first (see chapter 7.3.1).

1. Release hose clamps using pliers, then disconnect all hoses from the corresponding connectors
and remove the hoses.
Note: The hoses connected to the water cup may also be removed together with the water cup
(see illustration) and then disconnected from the connectors of the water cup outside the unit.

2.

Carefully pull fixing clip of the water cup to the front, then push water cup down from the hold­ing device and remove it to the front.

The installation of the water cup and the water hoses follows the reverse sequence. Before fixing

8 Malfunctions

Important! Most operational malfunctions are not caused by faulty equipment but rather by improper

installation or disregarding of planning guidelines. Therefore, a complete fault diagnosis always
involves a thorough examination of the entire system. Often, the steam hose connection has not
been properly executed, or the fault lies with the humidity control system.
