7. Coolant procedures
7.6
Cooling liquid visual check
Ensure the chiller is turned off before connecting the open-end hose to the bypass tube. If not, spillage will
occur.
How to perform
1. Connect the bypass tube to the main cooling circuit quick couplers as illustrated.

Connecting service hose to lower quick coupler
2. Insert the open end of an open ended hose (included in the service kit) into a container and connect the other end to the bypass
tube.

Note:
Ensure you
fi
rst place the open-ended hose in the container before connecting it to the bypass tube. If not, there is a big
chance you will spill
fl
uid.
3. Switch on the power.
The chiller will notice a pressure difference due to the open-ended hose and the pump will activate. As a result, cooling
fl
uid will
fi
ll the container.
4. Switch off the power after collecting about 1l of cooling liquid.
Note:
If the power is not switched off, the pressure pump will continue to pump cooling liquid in the tank in bursts of 30 seconds.
5. Perform a visual check. The cooling liquid should be blue (azure/cerulean) with only minor levels of particles being present.
-
If the cooling liquid is okay, add the coolant back to the tank. See procedure "Adding coolant to the tank", page 31.
-
If the cooling liquid shows unacceptably high levels of contamination or has changed color, the cooling liquid must be replaced
entirely. See procedure "Draining the coolant circuit", page 26.
