STARTING UP
Before running, this Manual must have been carefully read and the instructions followed; wrong
settings and operations are thus prevented that could cause operating faults.
After performing the operations described in the INSTALLATION chapter, the inverter can be
started. Before starting the system, the pumps must be primed (filling and air bleeding).
Switch-on
When the appliance is energised, it enters the initialisation phase, which lasts just a few seconds, after
which DGBOX begins the STARTING phase, which lasts 5 sec, after which DGBOX returns to the same
operating conditions in which it was when it was last switched off (in WORK mode or OUT OF
SERVICE mode). The STARTING phase is a standby during which DGBOX can be switched to OUT OF
SERVICE mode by pressing the START/STOP key.
Three possible situations are shown below which can occur at switch-on:
1. If DGBOX was in ON condition at last switch-off , after initialisation and the STARTING phase,
the system switches to WORK mode, and starts the pumps if a pressure is detected below that
set (see fig. below).

During initial setting of the base parameters (BASE SETUP) it is best for DGBOX to be in OUT OF
SERVICE condition; check to make sure the display screen appears as in the illustration below:
