2 Mounting position The pump is designed for tank mounting in vertical position. The pump is positioned in a hole cut into the cover of the tank (upper side) and is secured to the tank by four or two hexagon head screws through the holes in the mounting flange. We recommend to fit a sealing gasket between the pump flange and tank. Provide a clearance of minimum

50 mm above the motor to ensure cooling of fan-cooled motors (MTA 120,

200 and 100H). The pump is designed for indoor operation only. Pump Rated P2 [W] LpA [dB(A)]
