Fig. 8-13: Connecting the coolant hose (example)
When mounting the coolant hose, proceed as follows:
1. Remove the protective caps from the coolant port threads on the motor
and screw in the pre-assembled quick coupling.
2. Push the tube onto the connection piece (threaded adapter). Do not
bend or damage the motor-sided screw connection.
3. Screw the tube end with the mounting clamp tightly above the connec‐
tion piece.
● In service cases, the quick coupling can be disconnected from the
lock nipple by means of the coupling. It is not necessary to discon‐
nect the tube connection.
If a different connection method is used on the tube side, other mounting
steps may be required. Mounting instructions can be obtained from the man‐
ufacturer.
To supply MAF motors with coolant, other installation materials
are also required, for example, tubes and mounting clamps (these
are not included in the scope of delivery).
The maximum coolant supply pressure of 6 bar applies to all MAF motors
based on the effective current pressure directly at the coolant connection on
the motor.
Please observe that additional screw connections or junctions in the cooling
circuit can have a negative influence on the flow and supply pressure of the
cooling medium.
