Qualication of personnel
All work described in this addendum manual may only be carried out by specialists who are well
trained and adequately qualied and are authorized by the customer.
For safety and warranty reasons any action beyond the scope of this manual must be carried out only
by qualied personnel authorised by the manufacturer.
It is assumed that all persons working with the submerged UV system and the Condair ME Control are
familiar and comply with the appropriate local regulations on work safety and the prevention of accidents.
Intended use
The submerged UV system is intended exclusively for the operation in the evaporative module of the
Condair ME Control. Any other type of application, without the written consent of the manufacturer, is
considered as not conforming with the intended purpose and may lead to the submerged UV system
becoming dangerous.
Operation of the equipment in the intended manner requires that all the information contained in this
addendum manual as well as in the installation manual and operation manual of the Condair ME
Control are observed (in particular the safety instructions).
Danger that may arise from the submerged UV system
DANGER!
Risk of electric shock!
The optional submerged UV system contains live mains voltage. Live parts may be exposed
when the junction box and the Condair ME control unit is open. Touching live parts may cause
severe injury or danger to life.
Prevention: Before commencing any work on the optional submerged UV system disconnect the
mains supply voltage to the Condair ME control unit via the electrical isolator in the mains supply line,
and secure electrical isolator in “Off” position against inadvertent switching on.
WARNING!
The UV lamps used in the submerged UV system emit harmful UV-C rays that can cause lasting
damage to eyes and skin.
Prevention: The lamps must be installed underneath the banks of the evaporative cassettes out of
direct line of sight. Never operate the UV lamp outside the evaporative module.

6For your safety
Warning!
Risk from mercury contaminated glass!
The lamps used on the submerged UV system are constructed and operated with technology similar
to that of domestic, uorescent lamps. The lamp is lled with gas and mercury vapour at low pressure
and will not explode. However, if broken there will be a risk from mercury contaminated glass.
Prevention: Dispose broken lamps separately in accordance with your local recycling laws and regul
ations.
Safety reporting
All persons working with the submerged UV system are obliged to report any alterations to the submerged
UV system that may affect safety to the owner without delay and to secure such systems against
accidental power-up.
Prohibited modications to the unit
No modications must be undertaken on the submerged UV system without the express written
consent of the manufacturer.
For the replacement of defective components use exclusively original accessories and spare parts
available from your Condair representative.

7System Overview / Principle of Operation
3 System Overview / Principle of Operation
Submerged UV System consists of the following components:
– Power distribution box
– 1, 2 or 3 UV lamps in waterproof sleeves (depending on size of the evaporative module)
– 2 mounting brackets per lamp
Fig. 1: Scope of delivery
Principle of Operation
The UV lamps are positioned in the tank underneath the banks of the evaporative cassettes.
When the water level in the tank reaches the lower operating level the lamps switch on. UV light is ef-
fective in killing bacteria in water systems. However the Condair ME system should always be supplied
with a clean water supply (refer to installation manual and operation manual).

8Installation work
4 Installation work
4.1 Installing the UV lamp(s)
The installation procedure is dependant on whether the submerged UV system is retrotted on an exist-
ing Condair ME Control system or on a new Condair ME Control system.
Note: Steps 1 to 4 must be performed only, if the submerged UV system is retrotted on an existing Con-
dair ME Control system. If the submerged UV system is installed on a new system proceed with step 5.
1. Isolate the water supply (close shutoff valve in the water supply line).
2. Drain the tank fully.
3. Isolate power supply to the control unit.
4. Dismantle droplet separator banks (if applicable).
5. Attach mounting brackets into corresponding slots of the cross bar.

10 Installation work
4.2 Installing the power distribution box
The power distribution box is supplied with a ying lead already connected to the corresponding termi-
nals inside the power distribution box. The power distribution box can supply up to three separate lamps
and is to be installed on the airoff face of the tank using the bracket provided. Placement of the box will
depend on what space is available and the direction of the inlet and drain pipe runs.
1. Select the position for the power distribution box to be placed, the attached bracket is designed to
t over the folded edge of the airoff face of the tank. The box must not be placed at the ends of the
tank and should be positioned away from the power and water connections of the hydraulic module.
Note: if required the power distribution box can be positioned away from the tank, although the length
of cable from the UV lamp to the box must be taken into consideration. The standard length of this
cable is 2 metres, alternative positioning may not be possible on systems with more than one lamp.
2. Connect UV lamp cable(s) to one of the available plugs on the side of the power distribution box
(which one does not matter).
Note: number of plugs depends on the number of lamps on system
3. Run the 3 core connecting cable out the AHU to the Condair ME control unit.
Note: The cable feed through must be done by the customer and must be equipped with cable glands.
4. Secure 3 core connecting cable with cable ties at suitable intervals along the cable run to the Condair
ME control unit.
Note: ensure 3 core connecting cable is placed in such a way that the insulation is not damaged
by sharp edges and so that it does not create a trip hazard or hinder correct maintenance of the
components.

11Installation work
4.3 Connecting the 3 core connecting cable to the terminals in the control unit
1. Isolate power supply to the Condair ME control unit.
2. Remove the front cover of the control unit.
CAUTION!
Electronic components are very sensitive to electrostatic discharge. Before proceeding with the
next step, appropriate measures (ESDprotection) must be taken to prevent damage to electronic
components.
3. Open the control unit inner door.
4. Lead 3 core connecting cable across the rectangular cable leadthrough into the control unit and cut
cable to length required.
4. Connect earth, live and neutral wires of the 3 core connecting cable to terminals “U.V.” according to
the wiring diagram below and the applicable local regulations. Ensure the cable between the AHU
and control unit is secured and tidy.

13Submerged UV lamp replacement
6 Submerged UV lamp replacement
In order to ensure continued disinfection, it is important that the UV lamp is replaced every 12 months.
Although the lamp may still be emitting UV light, the performance may have deteriorated to less effec-
tive levels.
To avoid risk of leaks at the sealing grommets from incorrect assembly, Condair Plc only offer complete
lamp assemblies. These include the cabling and plug for quick and easy replacement.
Safe disposal and risk through damage to lamps
Please dispose of used lamps separately in accordance with your local recycling laws and
regulations. Waste electrical and electronic equipment may contain hazardous substances,
which, if not treated properly, can be harmful to the environment and human health. Specic
treatment of waste electrical and electronic equipment is therefore essential.
Warning!
Risk from mercury contaminated glass!
The lamps used on the described system are constructed and operated with technology similar to that
of domestic, uorescent lamps. The lamp is lled with gas and mercury vapour at low pressure and will
not explode. However, if broken there will be a risk from mercury contaminated glass. Dispose broken
lamps separately in accordance with your local recycling laws and regulations.
