Before switching on the hydraulic unit:
• Check the electric wiring.
• Check the refrigeration circuit and make sure the gas
supply has been performed.
• Check the pressure of the hydraulic circuit (1-2 bar),
check that the heat pump is purged, and the rest of the
installation.
• Make sure that ALL DIP SW are OFF before starting
up
