Page 13: Mode Of Operation
User Manual Mode of Operation When the fan of the NPU is running, air is sucked through the filters of the machine caching airbourne dust particles near the filter system. The large air flow through the NPU creates a flow of air and dust particles directed towards the filter system. -
Page 14: Start-Up
User Manual Start-up When the NPU has been correctly assembled and connected, it can be switched on and off at the start/stop switch (1) on the fan housing. The filter load is indicated by the manometer (2) Fan adjustment switch (3) (1-2-3 step of operation) Continuation of grounding (4) in case of using tools that require potential equalization for the NPU. - Page 15 User Manual RONDA NPU can be connected to an inlet hose. Using an inlet hose will make it easier to catch dust from specific processes (drilling, sanding, cutting etc.) If an outlet hose is not connected, the outlet air can raise dust from the floor resulting in risk of dust exposure.
-
Page 16: Hose Connection
User Manual Hose Connection The use of inlet/outlet hoses will reduce the air flow inside the NPU depending on diameter, length and how the hoses are laid out (bendings and winding). The air outlet of the machine should always be lead outdoors, if possible. Handling, operation and storage Always lift by the handles on both sides of the machine. -
