4. Installation
The pump must be installed so that per-
sons cannot accidentally come into con-
tact with the hot surface of the motor.
4.1 Pump location
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 hexagon head screws through the
holes in the mounting flange. It is recommended to fit
a sealing gasket between the pump flange and tank.
Note: The pumps can only be mounted in vertical
position. The MTC 2 and 4 must have access to the
tank from the drain channel in the motor stool.

4.2 Suction conditions
The bottom of the pump strainer must be at least
25 mm above the bottom of the tank.
The pumps are designed to provide full performance
down to a level of A mm above the bottom of the
strainer.
At a liquid level between A and B mm above the bot-
tom of the strainer, the built-in priming screw will pro-
tect the pump against dry running.
