-Corrosive, or dusty.
Once at the place of installation, remove the wooden blocks.
-Di󰀨erent conguration options are possible:
• The unit can be placed directly on the oor. In this case:
The unit must be placed on a at, smooth surface which is as level as possible (ratio of approx. one to one thousand). The cabinet
frame must rest fully on its contact surface. The unit need not be anchored to the oor if it is operated under normal conditions.
• Or on one of the following bases:
Support base, cased base with grids, cased base with damper.
(See the technical characteristics for these options in paragraph 12.2).
It should be placed on a oor that is as level as possible.
Each base comes with feet, which allow the height to be adjusted (in the event of a raised oor) and the base to be levelled before
placing the unit on top.
Before placing the vertical unit on top, an adhesive seal (supplied with the option) is to be placed on the aluminium casing frame
to ensure its tightness.
The cabinet can also come with a plenum with grids or a free-cooling plenum.
(See the technical specications for these options in paragraph 12.2)
Before placing the plenum on the vertical unit, apply the adhesive seal (supplied with the option) to its tightness.
For practical reasons, when the CW 115 model unit is in its nal position, the
horizontal gussets (with round stamped holes), located at the bottom of the unit, can be removed (see photo).

10 - CONNECTIONS
When following these steps, please consult the dimensional drawing and connection diagram as well as the wiring diagram found
inside the vertical unit.
10.1 - Hydraulic connection
The hydraulic pipes must be routed through the plates provided for this purpose in the vertical unit frame. This is either done to
the right of the unit or directly underneath.
side plate
These plates must be drilled (water circuit + condensate draining) then retted in place before the hydraulic pipes are routed through
them.
For the CW115 model, the pipes on the right are routed through a xed insulated panel.
Foam panel
please see the dimensional drawing and connection diagram to locate the routing areas and connection positions.

Always use two spanners when connecting or tightening the hydraulic couplings to avoid twisting the pipes and applying stress on
the welds.
To avoid the risk of condensation, the hydraulic pipes and elements must be carefully insulated.
Before insulating, check the tightness of the couplings.
Warning: the operating pressure on the chilled or hot water network must not exceed 8 bar.
Once all the connections have been made, the access holes must be sealed.
Insulated exible connections are available on request for carrying out hydraulic connections. Ensure these are not bent too acutely
to avoid pinching the inner tube and restricting the ow of water.
Condensate drain
The condensate drain pan should include a siphon to avoid any risk of overowing. (See position and connection diameter on the
dimensional drawing).
In these vertical units, the pan is depressed due to its position in relation to the fan motor assembly.
To enable correct drainage, the height must be equal to at least twice the unit's depression.
MAGISTER®EN-10

A condensate drain pump option is available (see technical specications in paragraph 12), provided that the humidier option has
not been requested.
If the humidier option is selected, the discharge must not drain into the unit's drain pan. To have a single discharge for both,
connect the humidier drain downstream of the unit's drain pan.
Warning: the condensates from the humidier can reach 100 °C.
10.2 - Electrical connection
The electrical connections and wiring must be set up as shown on the wiring diagram included with the unit and in accordance with
applicable standards and regulations.
The unit's power supply cable must be determined according to the power of the unit, the length of the cable, the protection, and
the operating mode.
Check that the characteristics of the electrical power supply conform with the indications on the name plate.
Please ensure the unit is connected to earth, and that the power supply is always able to supply the necessary power.

11.2.2 - Electric heater
Operates in two on/o󰀨 stages or with TRIAC (modulating).
The latter allows the power of the electric heater to be varied to ensure it is as close as possible to the required heating capacity.
The connection is carried out in the factory. It is equipped with 2 safety thermostats, one with automatic reset
and the other manual.

11.2.3 - Humidier
Functions only with municipal water, and not with demineralised or softened water.
The humidier with immersed electrodes has a card known as CPY (mounted inside the box) to relay all information relating to the
humidier directly to the µAir Connect 2 controller. It adapts, within the allowable operating limits, to the physical and chemical
properties of the water used. Voltage is applied to the immersed electrodes, and an electrical current passes between them, heating
the water to boiling point. The water acts as an electrical resistor, ensuring continuity between the electrodes with a minimum of
dissolved salts.
(The water must have a conductivity of between 350 µS/cm and 125 µS/cm.)

Connection:
The humidier is supplied with a exible water supply tube at the back of the cabinet.
To drain it, carry out siphoning.
Warning: the water temperature can reach 100°C.
If the option without the µRC2.1 (CIAT) control has been chosen, there is a display in the cabinet which can be used to control
the humidier.

Connect a Ø 10 int (3/8") exible tube (not supplied by CIAT) to the pump discharge.
For OVER models (3 and 5), if using a spreader beam and slings, the PVC tube will not be directly connected to the pump,
for handling reasons. It must therefore be angled in the right direction and xed to the clamp, as shown below.
