17Product Overview
Functional description
The water tank is lled up to a preset upper level via the level-controlled inlet solenoid valve (NC). When
the water level in the water tank drops below a certain limit, the level-controlled inlet solenoid valve opens
until the upper limit is reached again.
The Nortec ME Control provides On/Off or stage control by means of the Nortec ME Control control unit
and the stage pumps. The Nortec ME Control control unit processes analog sensor/control signals and
uses them to control the stage pumps.
In case of a humidication/cooling request with activated On/Off control the inlet solenoid valve (NC)
opens and all stage pumps start and the water ows to the distribution headers above the evaporative
cassettes.
In case of a humidication/cooling request with activated stage control the inlet solenoid valve (NC)
opens, then up to ve stage pumps start (depending on the demand signal and evaporative module size)
and the water ows to the distribution headers above the evaporative cassettes.
The distribution pipes inside the distribution headers evenly supply the water to the entire surface of
the evaporative cassettes where it ows down and humidies the air owing through the evaporative
cassettes. The excess water not used for humidication ows to the water tank.
To prevent accumulation of mineral residues and the formation of germs in the water tank, the tank is
completely drained periodically (interval or time controlled). Additionally further hygiene functions can
be activated: Operation-dependent draining of the water tank (ll cycle, conductivity, temperature or
time controlled).

18 Operation
4 Operation
4.1 Important notes on operation
Qualicationofpersonnel
The Condair ME Control must be commissioned and op erated only by personnel familiar with the sys-
tem and adequately qualied for the respective tasks. It is the owner’s responsibility to verify proper
qualication of the operating personnel.
General notes
The instructions and details regarding commissioning and operation must be followed and upheld.
The initial commissioning of the Condair ME Control requires appropriately trained technical personnel.
It is strongly recommended that your Condair representative commissions your system. Part of this initial
commissioning process is a disinfection of the water tank, and if required the evaporative cassettes.
Please read this document in full before commencing any work.
Please pay attention to local regulations regarding working at heights and electrical work.
Safety and hygiene
DANGER!
The Condair ME Control must be operated in accordance with this manual. Failure to do so
could result in contamination that might cause Legionnaires’ disease, which can be fatal.
WARNING!
The Condair ME control unit should not be electrically isolated for periods exceeding 24 hours
as automatic drain and purge cycles will be disabled.

19Operation
4.2 Initial commissioning
The initial commissioning of the Condair ME Control requires appropriately trained technical personnel.
We strongly recommend that your Condair representative commissions your system.
Inspections
Prior to initial commissioning the complete system must be inspected for correct execution of the instal-
lations. Proceed as follows:
1. Switch off AHU.
2. Evaporative module installation: Check correct selection of evaporative module on rating plate if
multiple units on site. Check that the evaporative module has been installed level in all planes with
secure blanking plates to prevent air bypass. Check that there is sufcient access for cassette re-
moval during maintenance. Ensure assembly is securely xed, and that there is no visible damage.
Check that the evaporative module is installed in a waterproof section. Check evaporative module
(including tank) is free of dirt/ debris and clean as necessary.
3. Control unit installation: Check that the control unit is mounted in a convenient dry location outside
the AHU/air duct.
4. Supply water Installation: Ensure the water system in the building has been subject to a Risk
Assessment. The Condair ME Control must be connected to a clean, wholesome mains water
supply. It is the responsibility of the user to ensure that the water system complies with local regula-
tions and bylaws, particularly those for the control of Legionella microbes. The use of mains water
fed tanks and reservoirs is only permitted as part of a managed water treatment system. Check that
the evaporative module has a feed water supply in excess of 2 bar (29 psi) connected to the sup-
plied approved lling hose. Ensure that any hygiene options have been correctly installed. Check
all joints and ttings for leaks.
5. Drain installation: Check that the drain line is made according to the corresponding instructions
given in the installation manual. Ensure the drain line is connected to the main building drain and
that drain pipework is trapped to a suitable level for the applicable working duct pressure. Check all
joints and ttings. Ensure that the drain connection includes an air gap.
6. Distribution pipework: Check all water distribution pipework between the hydraulic module and
the distribution headers are securely tted.
7. Electrical wiring: Check all electrical connections with reference to the corresponding wiring diagram
in this manual. Check that a 100...240V / 10A single phase supply is connected to the control unit.
Ensure that this power supply is isolated with an electrical isolator within 1 m (39") of the control unit.
8. Optional controls: Check that appropriate controls connections have been made to the control unit.
Refer to the controls wiring section of the installation manual.
9. Flush water supply and test supply water quality: Disconnect water supply pipe from connector
on the hydraulic module. Fix hose to free end of supply pipe and lead hose to a drain. Carefully ush
supply pipe a suitable amount of time without creating splashing or aerosols.
Take a water quality sample to ensure that supply water meets the requirements specied in the
water quality guide. The sample should be tested using a dip slide to indicate the total number of
colony forming units per ml (cfu/ml). Generally, levels of 103 cfu/ml may be considered acceptable
for this type of humidier provided the species of microbes and/or fungi involved are themselves not
considered to be harmful. If you are unsure of the quality of your water please consult your Condair
distributor for advice.
Then reconnect the water supply pipe to the supply connector on the hydraulic module.
10. Perform pressure test: Turn on water supply and check for leaks. Ensure double check valve is
installed correctly.

20 Operation
After the system has been inspected and found correct proceed with the initial commissioning:
1. Ensure AHU is switched off.
2. Switch on electrical isolator, and then the <Control unit On/Off> switch on the control unit.
3. Enter the activation code (see chapter 5.5.2 – Performing maintenance functions – “Service” sub-
menu).
4. If the system is equipped with bre media evaporative cassettes (F75, F85, F95, C85, C95) perform
a matrix wash over cycle (see chapter 5.5.2 – Performing maintenance functions – “Service” sub-
menu).
5. Simulate full demand and check components are operating correctly.
6. Check correct water level and pump activation.
7. Check water can ow to drain correctly.
8. Allow system to ush until water is clean.
9. Test correct ow of water to distribution header.
10. Test any tted options (see relevant option addendum manual).
11. If evaporative cassettes have become dirty or damp, follow the disinfection procedure described in
chapters 6.3 and 6.9 of this manual.
12. Switch on fan of AHU and test operation with fans running and validate air conditions against the
design data.
13. From full saturation – time drain cycle (with fan in design condition).
14. Test control devices.
15. Correctly congure Condair ME control unit (setpoints, control settings, etc.) according to the situa-
tion on site (see chapter 5.4 – Conguration).
16. Drain tank, wipe tank clean, re-ll tank and add DISIFIN XL chemical according to tank volume.
