Mechanical joining between sections 

 
Each ordered section is already provided with anti-vibration support plates, like the basic unit. Lay sections and basic unit 
according to the right sequence of air treatments and to the right airflow direction. As best as possible, depending on how 
many sections and their weights, connect first the premounted sections as described above and then fix these parts to the 
supports (see previous “Machine positioning”). 
With referement to the 

figure 5

, the following are instructions to join the selected sections each other : 

Apply the adhesive airproof gasket, supplied with the section, on the joining surface 

Put the sections to be joined close to each other 

Pass the screw M8 x 25 (1) through the holes, while paying attention to the washers (2) 

Screw the bolt (3) by hand 

Fix the bolt with a suitable key 

Fix the upper plates, supplied apart together with the section. 

 
 
 

Air duct connections 

 

 

 

 

Size the air duct according to the plant purpose and to the unit air performance. 

 

Adjust unit sound level according to the required target, eventually by installing suitable sound attenuators. 

 

Fit insulated ducts as best as possible to prevent water condensation. 

 

Fit an antivibrating joint at air intake and air outlet in order to avoid any transmission of unit vibrations into the room. 

 

Ensure the electrical continuity between the ducts and the apparatus via a ground cable. 

 

 

Water connections 

 
The installation and connecting of the piping is an operation that must be done correctly, otherwise it may compromise the 
performance of the system. At worst it may cause irreversible damage to the machine. These operations are to be 
effectuated by 

qualified personnel.

 

 

Condensation outlet connection 

 

The system of drainage must provide an adequate trap able to allow the condensation run off on underpressure 
conditions. 

 

The trap must be designed as shown on the  

figure 6

 

 

The trap must have a tap for correct cleaning of the lower part, and must allow an easy disassembly. 

 

The path of the condensation drainage tube must always have a gradient toward external. 

 

Insure that the condensation run-off tube does not interfere with discharge of the unit. 

 

Water coil connection 

 

The water heating or cooling coil is supplied with GAS “female” threaded headers. 

 

The tightening must be carried out with extreme care to avoid damage to the copper collectors of the coil. 

 

The path of the tubes must be studied in a way to avoid obstacles should it be necessary to extract the unit coil. 

 

Water inlet and outlet must be so that the heat exchange is under counterflow condition. Follow instructions found 
on the WATER INLET and WATER OUTLET plate. 

 

Provide an air valve at the top of the unit, and a water discharge valve at the bottom. 

 

Reinforce sufficiently the units external tubes to avoid offloading the weight onto the coil. 

 

Once connection has been effectuated, fix the external seal flush against the control panel, in this way avoiding the 
passing of air. 

 

The insulation must not rest against the panelling, as this may provoke burning. 

 

For control purposes, organize the interception of the tube side coil when the fan is off, to avoid internal overheating 
and possible damage to internal components. 

 

Provide an anti-freeze system. 

 

Provide a cut out switch to isolate the coil from the rest of the circuit in case of extensive maintenance needs. 

 

Should the unit be installed in particularly cold areas, drain completely before plant shut-off long periods. 

 
 

IMPORTANT: IT IS IMPORTANT NOT TO PLACE IN OPERATION THE UNIT IF THE FAN OUTLETS ARE 
NOT DUCTED OR NOT PROTECTED BY A SAFETY NET ACCORDING TO THE ACTAUL REGULATION.
