● Make sure that all provided covers, guards, hoods, etc. are mounted. If the machine is installed at an altitude greater than 1000 meters above sea level: ● Contact your Busch representative, the motor should be derated or the ambient temperature limited.
● Busch recommends the use of the optional horizontal inlet filter and the water separator to col- lect the condensate and prevent it from flowing into the pump.
Risk of premature failure! Loss of efficiency! ● Only use an oil type which has previously been approved and recommended by Busch. For oil type and oil capacity see Technical Data [➔ 36] and Oil [➔ 37]. The oil level should stay constant over the lifetime of the oil. If the level does fall, this indicates a leak and the machine requires repair.
● If the machine is equipped with a power connector, install a residual current protective device to protect persons in case of isolation default. ● Busch recommends installing a type B residual protective device suitable for the electrical in- stallation.
