Set up operation/transport
The vacuum pumps supplied without electrical plug must be equipped with an electrical
triple-pole plug according to the norms and regulations of the country where the vacuum
pump will be used. The plug must be 󰊟tted by a trained professional. The electrical power
supply, with which the vacuum pump will be run, must be in accordance with the voltage
and frequency indicated on the rating plate of the vacuum pump. The vacuum pump must
only be connected to a fused electric installation.
The vacuum pump is supplied without oil 󰊟lling. Prior to the 󰊟rst operation the vacuum
pump must be 󰊟lled to half level of the oil sight glass (Pos. 20) with the oil provided (DV-
44/DV-45). The oil is being 󰊟lled in through the port of the oil mist 󰊟lter (Pos. 19).
m Only 󰊟ll oil up to half level of the oil sight glass. Re󰊟t the oil mist 󰊟lter (Pos. 19) after
󰊟lling.
m Remove the 󰊠are cap from the intake port to start the pump (with model RL-8 also turn
the ball valve to open position). Connect the charging hose to the intake port as soon
as the pump motor reaches full speed.
m Running the pump without being connected to a system and pulling vacuum will result
in extensive exhaust of oil mist through the oil mist 󰊟lter.
