Ƒ

1. install a manual valve upstream of the installation (to be able to cut off the water supply);

2. connect the humidifi er to the water supply. On models

UE001 to UE0018, use a hose with 3/4’’G fi ttings (see par.

11.2 “Technical specifi cations” , compatible CAREL hose: code

FWH3415000). On models UE025 to UE065 connect the hose with the non-return valve supplied (code FWHDCV0000) to prevent the water inside the humidifi er from coming into contact with the mains water;

3. install a mechanical fi lter to trap any solid impurities (to be connected downstream of the tap);

4 connect a section of non-conductive pipe or hose for draining

(resistant to temperatures of 100 °C (212 °F) and with a minimum inside diameter of 40 mm/1.6”);

5 prepare a funnel to interrupt continuity in the drain line;

Fig. 2.a

Ƒ

Ƒ

6 connect a drain trap to prevent the return of bad odours

(minimum inside diameter 40 mm/1.6”);

7 in models UE025 to UE0065: connect a drain hose from the bottom tank of the humidifi er (this can run into the drain funnel).

Important

: when installation is completed, fl ush the supply hose for around 30 minutes by piping water directly into the drain, without sending it into the humidifi er. This will eliminate any scale or processing residues that may block the drain pump and cause foam when boiling.

Important:

•

•

• do not treat the water with softeners, this may cause the entrainment of foam, aff ecting the operation of the unit; do not add disinfectants or anticorrosive compounds to the water, as these are potential irritants; the use of well water, industrial water or water from cooling circuits and, in general, any potentially chemically or bacteriologically contaminated water is not recommended.

2.2 Drain water

•

•

• this contains the same substances dissolved in the supply water, however in larger quantities; it may reach a temperature of 100 °C (212 °F); it is not toxic and can be drained into the sewerage system.

Important:

1.

2. fi t the distributor at a slight incline (at least 2°, to prevent the return of condensate); the “L”-shaped mounting support (see part 1 Fig. 3.c) is supplied with steam distributor models from DP085* to DP025*. For shorter lengths, the support can be supplied as an option (code 18C478A088).

3.2 CAREL linear distributors for air ducts

(DP***DR0)

Install away from obstacles (curves, branches, changes in cross-section, grills, fi lters, fans).

Minimum distance between the distributor and the obstacle: 1/1.5 m

(3.3/4.9 ft). Increase the distance if:

•

• the air speed increases in the duct, the relative humidity of the air increases before and after

• humidifi cation, the turbulence decreases.

See page 33 for installation examples.

•

•

Assembly instructions (see Fig.3.b

):

• make a series of holes on the wall according to the distributor drilling template (included in the packaging with the distributor); insert the distributor with the steam holes facing upward; fasten the fl ange using 4 screws.

3.3 CAREL steam blowers (VSDU0A*, models

UE001 to UE018 only)

Steam distributors for humidifi ers with fl ow rates up to 18 kg/h (39.7 lb/h). Can be connected on top of the humidifi er, or separately in another location (see the fi gure below).

3.4 Steam hoses

•

•

•

•

• use CAREL hoses (max. 4 m long, see “Models of steam hoses”, page 3 0).

Rigid pipes may break and cause steam leaks; avoid the formation of pockets or traps (causes of condensate); avoid choking the hose due to tight bends or twisting.

fasten the end of the hose to the connectors on the humidifi er and the steam distributor using metal clamps, so that these do not detach due to the high temperature.

avoid solicitations involving stress on the shank out of steam cylinder.

3.5 Condensate drain hose

During the operation of the humidifi er some of the steam may condense,

To drain the condensate, connect a drain hose with a drain trap and a minimum slope of 5° to the bottom of the humidifi er (see Fig. 3.d). CAREL condensate drain hoses: code 1312353APG

Important : he drain trap in the condensate drain hose must be fi lled with water before starting the humidifi er.

Example of correct and incorrect installation of the steam hose and condensate drain hose.

4.2 Power cable connection

Before making the connections, ensure that the machine is disconnected from the mains power supply.

Check that the power supply voltage of the appliance corresponds to the value indicated on the rating plate inside the electrical panel. Insert the power and ground connection cables into the electrical panel compartment using the tear-proof cable gland supplied, or through the cable gland with cable stop, and connect the ends to the terminals (see

Fig. 4.c). The humidifi er power line must be fi tted, by the installer, with a disconnecting switch and fuses protecting against short circuits.

Table 11.a lists the recommended cross-sections of the power supply cable and the recommended fuse ratings; note, however, that this data is purely a guide and, in the event of non-compliance with local standards, the latter must prevail.

Note: to avoid unwanted interference, the power cables should be kept apart from the probe signal cables.

Depending on the type of signal used, steam production can be enabled and/or managed in diff erent ways (ON/OFF or modulating)..

Steam production is enabled by keeping terminals M2.4 and M2.5 closed.

1. Enable steam production using:

HUMIDISTAT (ON/OFF action)

•

•

• connect inputs M2.2 and M2.3 (production request) to a humidistat; jumper inputs M2.4 and M2.5 (enable); set parameter A0=0 to enable the ON/OFF action.

9.3 Cleaning and maintenance of the cylinder

Replacement

Important: he cylinder must be only be replaced by qualifi ed personnel, and with the humidifi er unplugged from the power supply.

In normal conditions, the disposable cylinders should be replaced after one year (or 2500 hours of operation, if cleaned periodically), while the openable cylinders last 5 years (or 10,000 hours of operation, if cleaned periodically). They must be replaced immediately – even before the specifi ed intervals – if any anomalies occur. For example, when the lime scale inside the cylinder prevents the correct fl ow of electric current.

7.

Replacement procedure::

1.

2. empty all the water (see chap. 6); turn off the humidifi er (switch “0”), and open the mains disconnect switch on the power supply (safety procedure); wait for the humidifi er and the cylinder to cool down; remove the front cover; disconnect the electrical cables from the cylinder; release the cylinder from the locking device and lift it to remove it; insert the new cylinder (make sure that the model and the power supply of the new cylinder correspond to the rated data); fasten the cylinder; reconnect the electrical cables to the cylinder; replace the front cover; switch on the humidifi er; reset cylinder operating hour counter (see parameters da & db, chap. 7);

Activate the wash new cylinder procedure, pressing ENTER + DOWN for 5 seconds

Periodical checks

•

•

After one hour of operation: check for any signifi cant water leaks.

Every 15 days or no more than 300 operating hours: check operation, the absence of signifi cant water leaks, the general conditions of the casing. Check that during operation there are no arcs or sparks

• between the electrodes.

Every 3 months or no more than 1000 operating hours:

disposable cylinders: check operation, the absence of signifi cant

water leaks and if necessary replace the cylinder; openable cylinders: if there are signifi cantly blackened areas, check the deposits on the electrodes and clean them, using the specifi c electrode and gasket kit.

•

Every year or no more than 2500 operating hours:

disposable cylinders: replace;

openable cylinders: if there are signifi cantly blackened areas, check the deposits on the electrodes and clean them, using the specifi c electrode and gasket kit.

After 5 years or no more than 10,000 operating hours: replace the

• openable cylinder.

After extended operation, or when using water rich in salts, the solid deposits that naturally form on the electrodes may grow until attaching to the inside wall of the cylinder. If these deposits are conductive the heat generated may overheat the plastic until it melts, with the risk of very hot water being released.

Important: In the event of water leaks, disconnect the power supply from the humidifi er as the water may conduct electricity.

9.4 Mechanically draining the water in the cylinder

Drain due to gravity without activating the humidifi er, recommended if:

•

• humidifi er decommissioned; to empty the cylinder without switching the humidifi er on.

Mechanical drain:

• make sure that the humidifi er is not powered;

• remove the cover;

• activate the mechanical device under the cylinder (see part A, Fig. 9.e).

9.6 Cleaning and maintenance of the other components

•

• when cleaning plastic components do not use detergents or solvents; scale can be removed using a solution of 20% acetic acid and then rinsing with water.

Maintenance checks on other components:

Ƒ fi ll solenoid valve. After having disconnected the cables and the tubing, remove the solenoid valve and make sure the inlet fi lter is

Ƒ clean; if necessary, clean with water and a soft brush; manifold with drain pump. Check that there are no solid residues in the cylinder attachment, remove any impurities. Check that the gasket (o-ring) is not damaged or cracked, replace if necessary. Check that there are no solid residues in the drain hose;

Ƒ drain pump. Disconnect the power supply, remove the pump and clean any impurities. Clean the tank from any deposits and check that the water fl ows freely from the tank to the drain (corresponding to the drain pump);

Ƒ fi ll tank. Check that there are no obstructions or solid particles and that the conductivity measuring electrodes are clean, remove any impurities and rinse;

Ƒ internal tubing kit. Check that the pipes and hoses are free and clear of impurities, remove any impurities and rinse.

Important : after having replaced or checked the water circuit, make sure that the connections are tight. Restart the unit and run a number of fi ll and drain cycles (from 2 to 4), after which, applying the safety procedure, check for any water leaks.

Controlling production using variables I62 and I63

1. Via network, immediately after start-up, set D2 = 0 (D2 does not need to be set again if the board is not switch off ).

2. Set I2 = 0 for ON/OFF control (A0 = 0), I2 = 1 for proportional control

(A0 = 1)

3. Set I62 = 4 to send the request via variable I63. If A0=0, if I63 ≤50: OFF; if I63≥51: ON

4. Write the production request to variable I63, format 000 to 100 (0% to

100%).

Loss of network communication

If there is a loss in network communication, CPY stops the KUE unit by opening the contactor; CPY then goes into standby, without producing steam, and alarm E3 is displayed. Steam production resumes as follows:

•

Communication is restored with the external controller: CPY

• automatically responds to the request from the external controller, and alarm E3 disappears.

CPY is switched off and on again: CPY responds to the request from the external controller (if communication has been restored) or from the external signal (0-10 V, 4-20 mA, etc.) sent to terminals M2:1-2-3. In this way, if communication with the external controller is interrupted, steam production can be started again by switching CPY off an on again and sending the request using an external signal, 0-10 V (4-20 mA, etc.).

12. ADVANCED FUNCTIONS

12.1 Operating principle

Immersed electrode humidifi ers manufacture steam by boiling the water contained inside the cylinder. The heat required to boil the water is produced by passing an electrical current through the cylinder. This is done by applying a voltage to the electrodes immersed in the water.

Initially, when the cylinder is new or has just been cleaned, the current depends almost exclusively on the type of supply water: the more salts in the water, the higher the current, and the required steam production is achieved quicker. Over time the salt deposits in the cylinder increase

(these do not evaporate with the water), helping achieve the rated production. In steady operation, the level of production required is maintained automatically by controlling the current input, adjusting the level of water in the cylinder.

The salts that deposit over time cause the progressive depletion of the cylinder. To avoid excessive accumulation, the humidifi er automatically drains and replenishes a certain quantity of water at set intervals.

12.3 Supply water conductivity

Conductivity measurement and alarms

The conductivity of the supply water is measured by the conductivity meter when the fi ll solenoid valve is opened.

Two programmable alarm thresholds are available:

• b5: warning threshold (signal only without activating the alarm relay, automatic reset when the condition is no longer present);

• b6: alarm threshold (unit shutdown with activation of the alarm relay).

The alarm is activated when the reading exceeds one of the two thresholds continuously for 60 minutes, or alternatively instantly if the value read is 3 times higher than the threshold.

To disable the alarm signal, simply set the thresholds above the maximum value of the reading.

12.2 Control principles

ON/OFF control

The action is all or nothing, activated by an external contact that consequently determines the control set point and diff erential.

The external contact may be a humidistat, whose status determines the operation of the humidifi er:

• contact closed: the humidifi er produces steam if the remote ON/OFF contact is also closed;

• contact open: the production of steam ends.

Proportional control

The production of steam is proportional to the value of a signal “Y” from an external device. The type of signal can be selected between the following standards: 0 to 10 Vdc, 2 to 10 Vdc, 0 to 20 mA, 4 to 20 mA.

The entire range is indicated as the proportional band. The maximum production of the humidifi er, corresponding to the value maximum of the external signal, can be set from 20% to 100% of the rated value of the humidifi er (parameter P0).

The minimum production has an activation hysteresis, hy, equal to 5% of the proportional band of the external signal “Y”.

12.4 Automatic draining

The humidifi er automatically drains and replaces some of the water contained in the cylinder, to prevent an excessive concentration of salts following the evaporation process.

The drain pump is opened for a set time whenever the conductivity exceeds the maximum limit; this situation is measured indirectly by evaluating the evaporation speed.

During the automatic draining phase, the electrodes are off , so as to prevent the drain water from carrying current (the display shows “dr”).

Drain due to excess foam

With certain types of supply water, foam may form during the production of steam just above the water. This situation must be resolved, as it may cause water to be released together with the steam. For this purpose, two electrodes are fi tted on the top of the cylinder. When these electrodes detect the presence of foam, the humidifi er activates a series of repeated drain cycles. If the situation persists, the complete washing of the cylinder is activated.

Drain due to inactivity

In humidifi er does not operate for an extended time (it remains on but does not produce steam), the water in the cylinder is drained automatically, to avoid stagnation and hygiene risks. The inactivity time is set using parameter “bF” (default 3 days). The function can be disabled by setting parameter b1 ( see paragraph 11.6).

Powered draining

When running an automatic drain cycle due to excessive salt, the electrodes are not powered and the production of steam is thus reduced.

To keep the electrodes powered during the drain cycle set parameter b1

( see paragraph 11.6).

Draining due to a signifi cant reduction in the request for production

In the event of a signifi cant reduction in the request for steam production, the humidifi er, rather than wait for the level of water (and thus the production) to decrease due to the eff ect of the production itself, performs a drain cycle. The reduction in the request for steam production is considered signifi cant if the current is 33% higher than that relating to the requested level. This function can be disabled.

Set parameter b1 ( see paragraph 11.6)

41 “UE BASIC” +030220630 - rel. 2.1 - 30.05.2008

ENG

Periodical drain

When using water rich in substances such as humus and lime, a periodical drain cycle should be set for the cylinder to avoid accumulating residues.

To enable the periodical drain, set parameter b1 to 64. In this way, every

24 h the humidifi er will drain all the stagnant water in the cylinder, and the display will show code “dP” (periodical drain). If the periodical drain is enabled, the number of hours between two periodical drain cycles can be set using parameter “bE”.

Note:

For the manual drain function, see chap. 6, for the mechanical drain see paragraph 9.4.

12.7 LEDs on the control board

There are three LEDs fi tted on the expansion board, located above the control board (near terminal M15.1):

management

The humidifi er checks whether there is no supply water or the fl ow-rate of supply water is too low, by controlling if the current at the electrodes increases after opening the fi ll solenoid valve.

•

•

In this case, the humidifi er:

• displays alarm “EF” activates the alarm relay, opens the contactor and closes the fi ll solenoid valve for 10 minutes.

After the 10 minutes, the fi ll solenoid valve is opened, the contactor closed and the phase current measured: if it increases the alarm is deactivated, otherwise the procedure is repeated.

NOTE: the alarm is reset automatically and is managed according to the procedure described above.

12.6 Alarm relay switching

Once the operating hours corresponding to the cylinder maintenance request have been reached (“CY” alarms), the alarm relay (if there are no other alarms active) will switch for 10 seconds every 12 hours, until reaching the “Mn” alarm.

This function is activated using parameter b1 (see paragraph 11.6); normally disabled
