The quality of water being used in the Condair ML Humidication System should be checked prior to
system commissioning and comply with the guidelines in the high pressure pump manual.

The Condair ML Humidication System must be monitored for hygiene as part of the maintenance pro­gram. Please refer to the maintenance section for further guidance.

8 For Your Safety

XXXXXXX_EN_1905 Condair MLP

Guidelines for a Hygienic System

• Carry out a risk assessment of the water system using a competent person, and implement an ap­propriate monitoring and control program.

• Initiate procedures for changing lters, disinfection etc.

• Enter into a service contract that suits your company.

• Stop the system if polluted drinking water is found in your area.

• Avoid water temperatures between 77 °F (25°C) and 113 °F (45°C), which favour the growth of

Legionella.

• Do not stop the system unless it is faulty or leaking (avoid water stagnation).

• Refrain from closing nozzles or sections, unless there is leakage or a fault (avoid water stagnation).

• Disinfect the high-pressure system at least once a year and after every maintenance or repair. Always

carry out a complete system disinfection if it has been turned off for more than 48 hours.

• Have water samples taken and tested for harmful bacteria at least once a year.

• Conduct follow-up measurements until the system is clean if bacteria have been detected in the system.

Disinfection

Depending on the system hygiene, it is advised that preventative disinfection uid be added to the ex­ternal RO water tank at an appropriate frequency, but at least once a year.

Condair Ltd. recommends using the disinfection uid HaloSpray or Sanosil S010 AG 5% (part number:

155404000) to the System via the high pressure pump, desired concentration 0.1%. HaloSpray or Sanosil

is safe, non-toxic and eco-friendly which provides a prophylactic, disinfection dose and is effective against
all types of microorganisms, including Legionella and E.coli.

Please read the pump manual for more information on disinfection.

If you are in any doubt about the suitability of water quality, please contact your Condair distributor who
will be happy to support you.

4 Site Planning

4.1 Prior to Starting

The basic principles for planning described below are theoretical ones. In practice, the necessary hu­midication capacity is inuenced by parameters that cannot be covered by this documentation. For
this reason, the values that were determined in theory have to be complemented by practical values or
corrected in many cases. Condair’s technical service team will be pleased to assist you.

Notes on the planning of direct room air humidication systems in one or more zones.

Proceed as follows when selecting and/or dimensioning the air humidication system:

• Determine the volume of the room and the air changes

• Determine the set points (temperature and humidity/relative humidity)

• Determine the humidication areas

• Calculate the maximum humidication capacity

• Dene the device requirements

• Determine the placement of zone valves and hygrostats

4.2 General Notes on Positioning

The positioning of a system is always determined during planning and noted in the system documents.

Prior to mounting the ML Direct Room Humidication heads, ensure that all hose layouts, distances
between heads and atomization clearances have been considered and adhered to, as per the ML Heads
Installation Guide.

The recommended hose layouts, distances between humidication heads and atomization clearances,
are shown in the ML Heads Installation Guide. Consult local and national installation regulations. Condair
does not accept responsibility for violations of the installation codes.

The following general positioning notes, however, have to be read and complied with in any case:

• Make sure that the construction (rafter, beam, wall, pillar, ceiling construction, etc.) on which the
devices and/or system components will be mounted disposes of a sufcient load-carrying capacity
and is suitable for xing

• Position the Condair ML Direct Room Heads in such a way to enable the atomized mist to spread
freely. When the mist is prevented from spreading by obstacles (e.g. ceilings, beams, ventilation
ducts, airow, machinery, etc.), turbulences can build up and condensation may occur as a result.

• ML Heads Installation Guide shows the recommended clearances, of the expansion of the atomi­zation stream, and the clearances that have to be maintained. These are ideal and recommended
maximum capacities using ML nozzles. Different weather, climate and indoor conditions can alter
the spread and distance of the mist.

Condair MLP

• As shown in ML Heads Installation Guide, when the nozzles and humidication heads are placed
one opposite the other, make sure that a minimum distances are adhered to. This will avoid the
streams to condensate each other.

• Pay close attention to the airow of the room. Do not install humidication heads or nozzles in the
immediate vicinity of a supply, return or exhaust system or of a cold-air inlet.

XXXXXXX_EN_1905

11Site Planning

• Do not point humidication heads or their nozzles at cold parts of a building, e.g. outside walls,
windows, etc. (risk of condensation).

• Insulate cold-water pipes in the area of the atomizing stream (risk of condensation).

• The evaporation process absorbs heat from the ambient air. For this reason, make sure that the

atomized stream is not directed on persons or on places directly above workplaces.

• In order to guarantee optimum humidication, ensure that the atomizers are sensibly distributed in
the room.

• The system components have to be mounted in such a way to provide enough space for operation
and maintenance.

Please contact Condair’s Technical Service Team in case you have questions on positioning and clearances.

4.3 Experts on Site

Condair has expert technicians employed by Condair who can provide:

• Pre-site analysis

• Positioning and site assistance or recommendations

• Installation support

• Start-up and commissioning

• Bacteriological troubleshooting on site *

• Cleaning and disinfecting

• Preventive maintenance

• Repair and fault nding

• Training and guidance

*Condair uses an industry leading method for measuring bacterial activity in the water; the approved
and patented BactiQuant test. This, unique to Condair, eld test takes water samples from critical project
locations. Thereafter, the bacteriological quality of the water can be read within 30 minutes, and the
system can be disinfected if necessary.
Condair follows the guidelines in VDI 6022 for colony forming units (CFU) counts in humidiers. The
CFU count in the humidication water must not exceed 150 CFU/ml, corresponding to a maximum BQ
value of 52. Please contact your local Condair representative for further information about our services.

5 Product overview

5.1 General description

The MLP series is a high-pressure pump station for direct room humidication it’s developed by Condair
Group AG with focus on reliable and hygienic humidication solutions.

The MLP comes in ve basic models, MLP 100, 300, 500, 800 and 1000. The number indicates
the maximum continuous water outlet (high-pressure) at 943 psi (65 bar). If a larger capacity than
264 gal/hr (1000 l/h) is needed the MLP’s is made in versions with double or triple high pressure pumps
called e.g. MLP 2x800 or MLP 3x1000.

Important:

All components exposed to water are made of corrosion-resistant material. All hoses are steel-reinforced
and drinking water-approved.

The high-pressure pump is directly mounted on the electric motor. Power is supplied to the 3-phase
asynchronous motor via a magnet-operated protective motor switch. The high-pressure pump is pro­tected against dry running by a pressure switch in the inlet manifold. A temperature sensor monitors the
temperature inside the pump and protects it from overheating.

The control unit consists of a touch display and a PLC mounted in the IP 65-rated electrical cabinet as
well as a power board for control of the high-pressure pump and connection terminals for power supply
(208...480 V/3N~/50-60 Hz).

From the touch screen, the operator can easily change humidity set point in each section, adjust alarm
limits and view hour counters, logged alarms, trend curves, etc.

The pump station is electrically wired at the factory. At the installation site, main power supply, humidity
signal, external safety chain, step valves and additional options must be electrically connected to the
control unit.

6.4 Water connection

WARNING!

Do not open and ll hoses, pumps, lters or tanks with water if the system is not to be started

immediately after installation (48 hours). Stagnant water acts as a breeding ground for potentially
dangerous micro-organisms.

Before connecting the MLP to the water supply it must be ensured that the incoming water is as clean
as possible. These is done by running a hose from the supply to the drain and open the shut-off valve
completely. Let the water run to drain for at least ten minutes. Shut off the water again and connect MLP to
the water supply with the supplied hose (3/4"/59.1" (3/4"/1.5 m)). Condair recommends that the in coming
water is tested for bacterial contamination please contact Condair for further information on the subject.

8.2 Equipment protection

Pressure switch (inlet water)

The MLP has a pressure switch which monitors the inlet water pressure.

If the inlet water pressure drops, the controller will stop the pump, thus protecting it against dry running.
If the water pressure drops, the screen will display ‘PM Water pressure too low’.

Max. hygrostat to protect against excessive humidication

A max. hygrostat can be connected to the control unit. If humidity levels rise to a value that exceeds
the value set on the max. hygrostat, the system stops and the alarm lamp ashes. The system will not
restart until the alarm is acknowledged by pressing ‘Alarm reset’.

Temperature switch

The high-pressure pump is protected against overheating by a temperature circuit that measures the
current temperature in the pump. The temperature limits can be set individually.

If the temperature exceeds 122°F (50ºC), the pump will stop immediately and must be reactivated via
the reset button once the temperature has dropped again.

Description of touch screen

The screen has four F keys. Each of the keys is used to navigate between the different screen images.
When these are used, the individual key function is indicated in the description directly above the key.

The actual touch screen can be operated by gently tapping the relevant screen ‘buttons’ with your nger.

If you want to change a numerical value, press the relevant number key. This will make a numerical
keyboard appear on which the new value can be entered. Remember to enter any comma that may be
needed.

9.5 Troubleshooting

Qualication of personnel

Have faults eliminated by qualied and trained personnel only. Malfunctions caused by the electrical
installation must only be repaired by authorised personnel (e.g. electrician).

Repair work on the high-pressure pump may only be carried out by your Condair representative’s service
technician.

Safety

When eliminating faults, the MLP must be taken out of operation and prevented from further inadvertent
operation.

Make sure the power supply to the MLP is disconnected (test with a voltage tester) and that the stop
valve in the water supply line is closed.

A.1 Siemens Scalence Router (option)

This describes how to set up the Siemens Scalance S615, in
order to create a connection between PLC and external com­munication (e.g. BMS system).

It is assumed, that the Siemens Scalance S615 is properly con­nected to the mains supply and the patch cables are connected
to the PLC and to the HMI (if applicable).

The PLC should be connected in port P2-P4.

A.2 Optional Modbus TCP/IP

MODBUS communication TCP/IP

ML-System humidication controls with PLC control is available with an option that allows connection
to CTS / BMS systems via Modbus TCP / IP.

The physical connection is made with a standard Ethernet cable that connects the PLC controller with
a standard RJ45 connector.

The option includes changes in the software, and a list of setup and the addresses of parameters to be
transferred between the PLC system and CTS / BMS.

The connection gives actual humidity for each section and gennerel information om the system status.
And it is possible to change setpoint from the BMS system. In addition, there is also a current "status"
integer that describes the plant's operational status so alarms can be transferred to the BMS.

The Modbus TCP / IP connection is set up with ML-System's PLC as Server/(slave) – and the
BMS as a client/(master).

A.3 Setpoint

The ON-time for the pump, when the humidity is between setpoint and (setpoint - proportional
band), can be calculated after the formula:

T(on) = Period time x (1 - (humidity level - Setpoint + Pro.band)/Pro.band)

Example: Period time: 3 min., Setpoint: 80% RH, Pro.band: 30%, Minimum ON-time 0,2 min.

With the values from the example above the ON-time for 78, 70 og 60% RH is calculated:

If the humidity level in the room is 78% RH, the ON-time for the pump is:

T(on) = 3 x (1 - (78 - 80 + 30)/30) = 3 x (1 - 0,933) = 0,20 min. = 12 sec.

If the humidity level in the room is 70% RH, the ON-time for the pump is:

T(on) = 3 x (1 - (70 - 80 + 30)/30) = 3 x (1 - 0,667) = 1,00 min.

If the humidity level in the room drops to 60% RH, the ON-time for the pump is:

T(on) = 3 x (1 - (60 - 80 + 30)/30) = 3 x (1 - 0,333) = 2,00 min.

------------------------------------------------------------------------------------------------------------

New Proportional band: If the proportional band in the above example is reduced to 20% instead, the
ON-time for the pump will change quicker when the humidity drops in the room.

Period time: 3 min., Setpoint: 80% RH, Pro.band: 20%, Minimum ON-time 0,2 min.

If the humidity level in the room is 78% RH, the ON-time for the pump is:

T(on) = 3 x (1 - (78 - 80 + 20)/20) = 3 x (1 - 0,90) = 0,30 min. = 18 sec.

If the humidity level in the room is 70% RH, the ON-time for the pump is:

T(on) = 3 x (1 - (70 - 80 + 20)/20) = 3 x (1 - 0,50) = 1,50 min.

If the humidity level in the room drops to 60% RH, the ON-time for the pump is:

T(on) = 3 x (1 - (60 - 80 + 20)/20) = 3 x (1 - 0,0) = 3,00 min. (100%).

If the humidity level in the room drops below 60% RH, (setpoint - pro. band) the pump will run all the
time - Minimum OFF-time (PAU).
Note that the running time of the pump changes quicker when the proportional band is lower.

---------------------------------------------------------------------------------------------------------------

67Appendix-A

New Period time: If the period time is changed, the ON- and OFF-times will change accordingly.

Example: Period time in the example changes from 3 to 5 min.

Period time: 5 min., Setpoint: 80% RH, Pro. band: 20%, Minimum ON-time 0,2 min.

If the humidity level is 70% RH, the ON-time for the pump will be:

T(on) = 5 x (1 - (70 - 80 + 20)/20) = 5 x (1 - 0,50) = 2,50 min.

Monitoring of humidity and status signals:

As an option the PLC system can through an integrated website be connected to the customer's computer
over TCP/IP so that the client can access a page, that shows the status of the system with monitoring
of the current humidity in each section.

This page can be opened with most standard browsers - We have tested.

The website in the PLC:

Condair MLP

XXXXXXX_EN_1905

73Appendix-A

The system displays the current humidity as the page opens - most browsers will then update every
10 seconds. - But you can also manually refresh at any movement by pressing F5.

Also shown is a pump station operating status:

• Humidication stopped

• Humidication active

• One or more operating warnings – System still running

• One or more operating alarms – System stopped

In order to obtain access to the data, use an Ethernet connection directly to the PLC system data switch
located in the control unit to the left of the PLC system.
Use a standard web browser and enter the PLC xed IP address xxx.xxx.xxx.xxx in the address eld.
This can be done through the company's internal Ethernet network – with separate cable or with a laptop
directly into the switch. Perhaps, use a router to get going at this address.
(It is important here to remember that the PC must be located in the same virtual network as the PLC
does).
