14.6 Connecting the machine to the hydraulic system
Connection to the main water supply
The Primus requires two separate connections:
• connect a tube (internal diameter 14mm) to the UHP intensifier inlet
• connect a mains water supply tube (internal diameter 25mm) to the valve inlet A for the
piece washing system (if there is a centralised cleaning system)
If there is no centralised cleaning system:
• connect a mains water supply tube (internal diameter 14mm) to the baffle valve B located
on the optional water collection basin. A tube (supplied) will connect the basin outlet with the
water pump inlet C (optional) for the piece washing system
