Emergency Operations; Preventive Maintenance; Heat Exchanger Coils - S&P UTBS Serie Manual De Instalación. Instrucciones De Uso

• With the unit running, test the current drawn by each electrical component, checking to
make sure that the current does not exceed the limits for each component. Also make
sure there are no phase lags between the currents circulating on each line, except when
single-phase electrical components cause this.
• Test the total current drawn by the unit as a whole, also checking to make sure there are
no phase lags between the currents on the different lines.

8. EMERGENCY OPERATIONS

• If any problems are noted on the unit, turn it off using the emergency shut-off device.
• These emergency operations will generally be the result of some problem with the elec-
trical circuit, in which case you may have problems with the motors. You will therefore
need to disconnect the power to locate the fault, which may be inside the unit (short
circuit) or external to it (problems with the power supply, voltage variations, etc.).
• In the event of fire, it must be extinguished using suitable extinguishers. Extinguishers
should be appropriate for use on electrical fires.

9. PREVENTIVE MAINTENANCE

• Preventive maintenance is a preset programme of checks that is followed regularly to
prevent equipment breakdowns.
• The supplemental Building Facility Technical Regulations are applicable at all times to
maintenance standards, except when justified otherwise for technical reasons.
• The maintenance supervisor should keep a copy of the preventive maintenance recom-
mendations given below on file, making as many copies as needed for use.
• According to the equipment's operating needs, it is crucial to make a list of those ele-
ments that are needed to quickly resolve equipment faults. This list will serve to deter-
mine the spare parts inventory needed to be able to perform repairs quickly.
• A maintenance log should record each component serviced during maintenance, as well
as activities performed or repairs made.
• Maintenance staff must have access to a specific training programme.
• Before starting maintenance operations on the unit, turn off the unit's main switch. Elec-
trical shock can cause personal injury.
• Keep the following in mind when performing maintenance operations:
9.1. WATER COILS
• We recommend cleaning the coils once a year.
• Don't use abrasive cleaner.
• Brush off the fins that need it.
