INSTALLING THE SIPHON
It is important to ensure the siphon is correctly fitted, as per the diagram below. For a depression H in the condensate drain, the
sizing of the siphon must incorporate dimensions of 2H

5. SYSTEM START-UP
Commissioning must be performed by qualified personnel, trained in air handling technology. Keep all
inspection doors closed while the unit is operating.
Once the electrical, hydraulic and refrigerating connections have been carried out, proceed with system start-up for the unit,
checking the steps below:
• For units with DX coil, the refrigerating machine must be operational (system start-up of the refrigerating machine not provided
by CIAT).
• Check the tightness of all connections,
• Make sure that the inside of the unit is clean, and that there are no foreign bodies inside it,
• Check the wiring
• Check the electrical supply voltage and the ratings of the overload protections against the current ratings of each component,
• To configure the setpoints, refer to the control system manual,
• Simulate activation of the various electric components, controlled components and alarms,
• Check the currents:
-
Temperature alarm,
-
Air flow alarm,
-
Fan motor assembly
• Check the air flow rates
• After a few hours' operation, check the filter fouling condition.
CONTROL
For adjustment and configuration of the control system, refer to the corresponding manual provided with the unit.
