• The very first time the unit is switched on, we recommend setting the date and time in the Setup.

Standby

• The start-up display will look like the one below.
• Display for SB model with High- and Low pressure – Select either HP or LP using arrows up & down.

Run Mode

Single Booster with high and low pressure

The following screen displays will appear when the unit is in Run Mode.

• Screen display for High-pressure unit in Run Mode.
• Scroll down to return to STANDARD pressure.
• Screen display STANDARD pressure.
• Scroll up to choose HP and scroll down to choose LP.
• Screen display for Low-Pressure unit in Run Mode.
• Scroll up to return to STANDARD pressure.
• remain in HIGH or LOW-pressure Run Mode until otherwise is selected.

Overview of Main- and Sub-menus

Power Off

• When the unit is off the display will only show a small dot in the top right corner.
• In Off mode it is possible to access all menus without the pump running by pressing the OK button on the panel.

• In case of a warning, “WARNING” will appear on the display screen. When a warning is detected the machine will either stop or run with limited performance until the cause of the warning has been improved (eg. inlet pressure).
• To see further error/warning list and possible cause and remedy go to section 5.2.

Content of Main- and Submenus

• The control panel contains the below main menu screen displays.
• Scroll between the menus using the navigation buttons.
• Each main menu contains submenus which will be described subsequently.
