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.
The motor must not be exposed to direct
Caution
water/liquid sprays.
