In lack of the foot valve, an hand operated or electric vacuum pump may be used to expel air from the pump and suction pipes (see par. 7.2).
Check rotation direction in installation equipped with electric motor. When pumping non homogeneous liquids like sewage with solids in suspen-
sion, it's necessary to mix the liquids by a suitable agitator in order to facilitate the pumping (
Start the pump with the delivery gate valve slightly opened and when pump is running correctly open gradually the gate valve until

TLK pump may be supplied, on request, with a mechanic priming vacuum pump. The manual vacuum pump (

and keep it in that position until the priming is completed. Transmission is disengaged by releasing the lever (
