To connect the roughing pump:
Warning:
To avoid skeletal or muscle injury associated with lifting heavy objects, at
least two persons must lift the pump.
Warning:
To avoid burn injuries, allow the pump to cool before touching it or its tubing
connections.
1. To ensure proper ventilation, install the pump in a location that allows these clearance
distances for each side:
• 100 mm or more at the front, rear, and top of the pump
• 50 mm or more at each side of the pump
2. Connect the roughing pump's vacuum hoses and electrical cables according to the figures

squarely.
