Filters; Standalone Steam Humidifier - CIAT Climaciat Instruction Manual

Direct starting possible for motors below 5.5 kW.
Use star-delta or inverter starting for motors with a power above 5.5 kW.
For units installed in Europe, a frequency inverter must be fitted to conform to regulations (ErP directive).
If the frequency inverter is not supplied by us, we accept no responsibility for any damage to the motor, fan or unit.
Precautions must be taken, in particular:
- Comply with the local regulations and standards governing safety,
- Comply with the EMC levels for the installation environment required by the local regulations and standards. If necessary,
fit a filter upstream and/or downstream of the variator,
- Select the power cables based on the local regulations and maximum operating conditions to withstand
the nominal current indicated on the data plate of the variator and the motor. The cable must withstand a
temperature of at least 70°C in continuous operation. For the cable between the variator and the motor, use a
600 V AC shielded cable with 360° shield connection ("pig tail" shield connection not permitted). If necessary, fit a filter to
prevent bearing currents on the motor,
- Limit the frequency to avoid exceeding the maximum speed for the different rotating components (motor, impeller, etc.) and
the maximum permissible flow rate and pressure values for the various elements of the unit,
- A device should protect the motors if the fans are overloaded or jammed,
- Make sure the isolation dampers are open before authorising the ventilation,
- Ensure a fan delay when the electric heaters or GGS are stopped,
- Fit a minimum air flow control device if there is an electric heater or GGS.

7.6 Filters

Warning!
Follow the safety instructions (see § 2 - SAFETY INSTRUCTIONS).
The filter cells are flammable products, and the fire risk may increase depending on the elements filtered by the medium. Keep
the filters away from flames.
Mounting, cleaning and replacement of filters pose risks of allergies and irritation of the skin, airways and eyes. When working on
the filters, always use suitable Personal Protective Equipment.
ƒ Connection phases:
- 1. Clean all the components upstream of the filters and the duct networks.
- 2. Clean the filter support frames.
- 3. Warning: the filters may be packaged and not installed at delivery.
- 4. Unpack the filters.
- 5. Check the condition of the filters and the sealing gaskets.
- 6. Fit the filters in the frames provided.
- 7. Lock with the runner screws or hooks, depending on the assembly.
- 8. Clean the inside of the filtration box. Remove any impurities using a vacuum cleaner and/or a cleaning product
- 9. Make sure there are no foreign objects inside the box.
- 10. Install pressure drop measuring instruments if the unit is not equipped with this option.
ƒ Precautions:
- Keep a spare set of filters in a clean, dry place.
Filters are regulated components. Comply with the regulations, directives and standards in force at the installation site.

7.7 Standalone steam humidifier

ƒ This section only covers the connection of the steam diffusion rails.
ƒ Follow the instructions in the manufacturer's manual supplied with the unit when installing the hydraulic and electrical
connections on the standalone steam production unit.
7.7.1 Condensate drain pan connection
ƒ Refer to your dimensional drawing for the diameters of the connections and their positions.
ƒ Outlet on the front panel under the rails: threaded gas type steel connector.
ƒ Fitting the siphon (see § 7.1 "Condensate drainage siphons").
7.7.2 Connecting the steam and condensate hoses:
ƒ The air handling units are supplied with diffusion rails installed inside the unit.
ƒ Depending on their length, the ends of these rails rest on supports. Make sure the supports are in place. To add rails to the
unit at a later date, please contact your agency, who will provide you with the relevant materials.
ƒ Connect these rails to the production unit.
