7. COOLANT PROCEDURES
About this chapter
This chapter contains step by step procedures for the (partial) replacement and fi lling up of coolant (cooling liquid).
The Draining and fi lling procedures can only be triggered by the Chiller Service Tool while your computer is
connected to the chiller. Trying to do these procedures manually will have negative results. For more info on
the Service tool, see "Chiller service tool", page 9.
The most up-to-date instructions will be the software instructions. In case of difference in instructions, the
instructions of the service tool have priority over the service manual instructions.

7.1 First use of the Chiller service kit — Air removal procedure
About the Chiller service kit bypass tube
Ensure the bypass tube has no air particles inside by performing the following procedure. This procedure will extract all air particles
from the tube and released via the air trap of the Chiller.
The same procedure can also be used to remove air bubbles inside the chiller hydraulics circuits.
How to extract the air from the Chiller service kit bypass hose?
1. On a chiller that has a secondary (DMD) circuit, connect the bypass tube from the service kit to the secondary circuit connectors.
Or,
on a chiller without a secondary circuit, connect the bypass tube to the main circuit connectors.

2. Start the service tool and start the “ air removal ” wizard.
3. Follow the instruction of the wizard to extract all air bubbles from the tubing.
4. Once the wizard has completed, remove the tubing.
