10 - OPERATION
10.1 - First commissioning
■ Read the guides for commissioning any accessories very carefully and follow all advice.
■ Check that the supply voltage corresponds to that given on the data plate.
■ Retighten the connections of the electrics box.
■ Switch the unit on and check that all the fans are turning in the correct direction (direction of rotation shown on the labels).
In the event of abnormal noise coming from the fan motor assemblies, immediately switch off the power supply and contact us.
■ Ensure that the hydraulic circuit(s) are clean.
■ Start charging by bleeding the air remaining in the circuit using the vents provided in the top section.
■ Start increasing the pressure, then check that the pipe connections are fully sealed.
10.2 - If anomalies occur..
Please contact us if you require any help. Before contacting your CIAT agency, please check the following points:
- Are all fans turning in the correct direction? (check this against the labels)
- Is the supply voltage correct?
- Are the motors running at the correct speed? (check the input current)
- Has the uid direction been reversed during connection of the coil?
- Are the ns of the coil clogged?
- Are there any issues relating to air recycling or a poor air supply?
10.3 - Recommendations for use
Scaling and corrosion have a very negative effect on the operation and service life of the units. Therefore, only use treated
water or authorised uids (check the compatibility of any additives with the drycooler's materials).
