Draining the internal cooling circuit
The modules in each cubicle can be drained through the drain valves without draining the
whole internal cooling circuit.
WARNING!
Hot, pressurized coolant can be present in the cooling circuit. Do not work on the
cooling circuit before the pressure is released by stopping the pumps and draining
coolant.
1.
Attach hoses to each drain valve in the cubicle to be drained. Lead the hoses into a
suitable container. Make sure the ends of the hoses are not immersed in coolant at any
point so that air can displace the coolant in the system.
2.
Open the drain valves. Wait until all coolant has drained.
Note:
Draining coolant into the sewer system is not allowed.
3.
If required, dry the piping with compressed oil-free air of less than 6 bar.
4.
If the drive is to be stored in temperatures below 0 °C (32 °F),
•
dry the cooling circuit with air,
•
fill the cooling circuit with coolant specified under
Coolant specification (page 170)
•
drain the cooling circuit again.
Maintenance intervals
As a general rule, the quality of the coolant should be checked at intervals of two years.
This can be done by distributors of Antifrogen® L (see
) if a 250 milliliter
sample is provided.

Coolant specification
Coolant type
Antifrogen® L (by Clariant International Ltd,
) 25% or 50% mixture, available
from Clariant distributors and ABB Service representatives.
Note:
Do not dilute the coolant. It is ready to use.
Antifrogen® L 25% mixture is usable in storage temperatures down to -16 °C (3.2 °F).
Antifrogen® L 50% mixture is usable in storage temperatures down to -40 °C (-40 °F).
Note that operation below 0 °C (32 °F) is not permitted regardless of the freezing point of
the coolant.
