Installation
The motor must be connected to the drain line connection on the connection block; see Fig.
.0.
The flushing connection F on the connection block should be connected to the low pressure con-
nection. With bi-directional drives, use the connection with lowest average pressure. (Connection
to high pressure will increase the motor drain flow). This gives flushing of the radial lip seal. It is
advisable to fit the nipple and the hose to the motor before fitting the torque arm.
3.2.2 Draining and venting the motor
Horizontal mounting
When the motor is installed with the shaft in the horizontal plane, it can be drained without special
provisions for venting. The highest of the three drain outlets D1, D
or D must always be used;
see Fig. .8.
Drain line must be connected direct to the tank with a minimum of restrictions, to ensure that the
maximum housing pressure is not exceeded.

Vertical mounting
When the motor is mounted vertically, one or the other of the vent holes must be connected to the
drain line. Which of the holes that is to be used depends on whether the motor shaft is pointing
upwards or downwards.
Motor shaft pointing downwards
The motor must be connected to the drain connection in D1 or D and F, F or F4. See figure
.9.
