viously indicated herein, mounting of the unit on
the tank cover involves problems of proper asso

from the tank cover to the fan casing inlet which
opens to a vertical plane.
Thus for the purpose of horizontally mounting
the suction unit 22 on the cover l2, I form the
cover with a concave depression or -seat 26 gen

than thethickness of the fan casing of the unit

for seating a portion of the motor casing.
For the purpose of providing better lateral sup
port for the seated unit 22 I provide externally
ñlleted and internally concave risers 28 for seat
ing and laterally supporting the motor casing 24,
and I may further provide the cover with exter
nally convex elevated portions 29 extending from
the lateral end portions of the major depression
