5. Installation
5.1 Pump position
Fig. 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.

6. Electrical connection
The electrical connection should be carried out in
accordance with local regulations.
The operating voltage and frequency are marked on
the pump nameplate. Make sure that the motor is
suitable for the power supply on which it will be used.
The motor must be connected to a motor-protective
circuit breaker.
We do not recommend operation via frequency
converter.
Terminal box positions
The terminal box can be turned to another position.
●The terminal box can be turned to another
position after delivery.
(●) The terminal box cannot be turned to another
position after delivery. The pump must be
ordered with the terminal box in position 3
o'clock.
Fig. 7 Terminal box positions (top view)
Proceed as follows:
1. Remove the bolts securing the motor to the
pump.
2. Turn the motor to the required position.
3. Refit and tighten the bolts securing the motor to
the pump.
The electric motor should be connected to the supply
as shown in the diagram inside the terminal box
cover.
Warning
Never make any connections in the pump
terminal box unless the power supply has
been switched off.
