Checks before start-up

The heat transfer section is pressure-tested and the electric safety of the unit measured at the factory. The electric safety checking includes the steady-state and insulation resistance measurement of the protecting cable. The customer conducts all the measurements and tests (including the grounding resistance measurement), which are required in the operating country.

Before starting the unit
Ensure that none of the components are damaged.
Ensure that the unit is firmly in position.
Check the fixing of the mechanical parts.
Check the cleanness of the heat transfer section.
Check the suitability of the electric network.
Check the electrical connections.
Ensure unit grounding.
Fasten all the connection terminals correctly.
Check the fan tip clearance between the fan and fan collar.
IEC Fans: Ensure that the fan safe guards are installed.
Ensure that the fan heaters operate correctly: they are ON when the fan is not operating and OFF when the motor is running (Option).
After electric installations, check that the fans rotate properly and that the air flow direction is correct.
When the fans are running, check that there is no unusual noise, imbalance, etc. in the unit.
Ensure that there are no leaks.
