Task
When there is sufficient amount of coolant in the piping, coolant begins to overflow from the bleed hose
of the drive cubicle. Drain some coolant to get all air out of the system, then close the bleed, inlet and
outlet valves in the drive cubicle.
Lead the bleed hose of the next drive cubicle to a bucket, and open the inlet, outlet and bleed valves of
the cubicle. Fill and bleed the drive cubicle. Repeat the procedure for the remaining drive cubicles.
Open the inlet and outlet valves of all drive cubicles and let the remaining air come out through the
automatic float air vent (VA-103) of the cooling unit. The pressure in the internal circuit starts to rise.
Monitor the pressure on the pressure gauge (PT-203). Increase the pressure up to 100...150 kPa by
pumping coolant in from the fill valve (V0012 or V0014
the fill valve and stop the fill-in pump. Keep the fill hose still coupled for later use.
Open the pump bleed valves somewhat and let the air out. Check the pressure again, and add some
coolant if necessary.
WARNING!
Do not fill in too much coolant. Ensure that the maximum permissible operating pressure (600 kPa,
indicated by pressure gauge PT-203) is not exceeded.
Starting the cooling unit and checking the pressure
Connect power to the cooling unit.
Close the door of the cooling unit.
Start the pump for one or two minutes.
• With the control panel: Switch the control panel to the Local control mode (Loc/Rem key). Start the
pump with the Start key of the panel.
• External control device: The remote start options depend on the control location selection. See para-
meter 20.03 and the delivery specific circuit diagrams.
Ensure that the flow control valve (V0016) is set to the design position which is shown on the label beside
the valve.
Monitor inlet and outlet liquid pressures of the pump (01.01, 01.02) on the control panel (Inside the cooling
unit, there is also pressure gauge PT-203).
Stop the pump by pressing the Stop key of the control panel: The pressure gauge should indicate pressure
100... 150 kPa when the pump is stopped.
Re-start the pump for couple of minutes.
Listen for a humming sound or feel the piping for vibration to find out if there is still air left. If these
symptoms appear:
• Make sure that the shut-off valve for automatic float air vent (VA-103) is open.
• Stop the pump, open the pump bleed valves and let air out. If necessary, add coolant (until pressure
of 150 kPa is reached). Repeat the procedure until all air is removed from the system.
Stop the pump. Check that all drain and bleed valves are closed. Remove the filling hose.

Task
Check that the number of pumps setting corresponds to actual number of pumps (20.04).
Two-pump unit ACS880-1007LC-0195: Activate and tune the delays of the automatic pump alternation
function (20.01, 20.05, 20.06).
If the drive and the cooling unit will be out of use for long time periods, activate the Standby function
(20.08).
