The pump is designed for tank mounting in the
(-50 to
vertical position. The pump is positioned in a
+70)
hole cut into the cover of the tank (upper side)
and secured to the tank by hexagon head
screws through the holes in the mounting flange.
We recommend to fit a sealing gasket between
pump flange and tank.
For ventilation and cooling, leave a clearance of
minimum 2" (50 mm) above the motor.
The pump is designed for indoor operation only.
Do not spray liquids directly on the motor.
