Startup and shutdown procedures
Check that the water filter is clean.
Check that all service valves are open.
Check the correct structure of the water supply.
Check that all pipes are filled with water and that air has been evacuated.
Check thermometers (not included from factory).
Check the pressure gauges (not included in the delivery).
If the hydraulic circuit contains air, it may compromise the operation of the unit.
CHECKING THE ELECTRICAL SOURCE
Verify that the circuit breaker is of the correct rating for the unit.
Check that all electrical connections are secure.
Check for false ground contacts as well as all wiring.
Check the internal control and power connections.
Measure voltage on all units, ground, neutral and 3-phase line.
Check that motor overload protection conforms to design requirements and is in automatic mode.
Check voltage (*Motor save), which is set to supply the correct supply voltage for the unit.
* The percentage of unbalance of the power supply must be calculated with the following formula, and adjusted with the UNBALANCE
command.
UNBALANCE PERCENTAGE = [(MAXIMUM AVERAGE DEVIATION) / (AVERAGE)] X (100)
Regular operation
Delayed start
Reverse phase
Phase unbalance
High/low voltage
NOTE: The units are factory set, however the power supply may vary in each installation and due to this imbalance must be
adjusted prior to start-up in order to protect the motors and electrical components of all units.
