Note
It goes without saying that equivalent products from other manufacturers may be used. Our
recommendations should be considered as such. We cannot accept any liability for the
quality and properties/features of third-party products.
Service and maintenance
It is recommended that the filling level and discoloration or turbidity of the coolant is checked
at least once a year. Further, every year it must be checked as to whether the coolant still
has the permissible specification.
If the coolant level has dropped, the loss should be corrected on closed or semi-open circuits
with a prepared mixture of deionized water and inhibitor or Antifrogen N.
3.2.4

Coolant connection

The motor is connected to the cooling circuit by means of two female threads on the rear of
the motor. Which one is the inlet and which one is the outlet can be freely connected.
Coolant connection for 1FT7: G 1/4 "
The units should be connected with hoses to provide mechanical decoupling (refer to the
table "Materials and components of a cooling circuit").
