etc.). Customers must assembly the extension hoses themselves, as
described below:
1. Shorten the heat exchanger hose to the required length.
2. Attach the connector with hose sleeve at one end using a hose
clamp.
3. Using a funnel, fill the hose with the cooling medium provided.
Connector and couplings have self-closing valves.
4. Attach the coupling with hose envelope at the other end of the heat
exchanger hose using the hose clip.
Connect the drive converter to the heat exchanger using the heat
exchanger hoses which have been filled with cooling medium. The valves
of the connectors and couplings are self-closing which means that no
liquid leaks-out when the heat exchanger hoses are connected or
withdrawn. In order to vent the cooling system, the drive converter should
be powered-up several minutes, so that the pump circulates the water in
the cooling circuit. Smaller air bubbles in the cooling medium, which form
when the extension hoses are connected-up, collect in the equalization
chamber. After the air has been vented, check that the cooling liquid level
is at the center of the equalization chamber. If this is not the case, cooling
liquid must be added to the equalization chamber. The sheet steel cover
of the heat exchanger must be removed to do this.
If the heat exchanger was connected up as described above, then it is no
longer necessary to add liquid in the equalization chamber.
Servicing the cooling medium circuit
The cooling medium circuit is an enclosed cooling system and has neither
to be serviced nor checked. If the "unit overtemperature" fault occurs in
operation then the level of the cooling liquid should be checked to ensure
that it is still at the center of the equalization chamber.
WARNING
If other anti-freeze agents are mixed, this can
result in deposits which could accumulate and
destroy the cooling system!
⇒
Do not mix the cooling medium with other anti-freeze
agents!
⇒
If other anti-freeze agents are mixed, this can result
in deposits which could accumulate and destroy the
cooling system!
