Check that the hose lines are connected correctly and tightly to prevent the coolant leak.	-	-
Check that power and signal cable for Water Chiller are connected correctly.	-	-
Check that all the breakers are OFF.	-	-

Observe that there is no leakage.
Check the Cabinet Monitor and leakage LED is not lit for each sensor.
Note:
There are three Leak sensor routes.
- Leak Sensor 1 (5142232, 5138563)
- Leak Sensor 2 (5151295, 5151296, 5151297, 5142231, 5138564)
- Leak Sensor 3 (5151297-2, 5142231-2, 5142224)
If the Leak Sensor1 detects the leakage, Main Breaker is tripped and System will be shut down.

If the Leak Sensor2 detects the leakage, LK2 LED is lit and error message is displayed on Host and Emergency Stop will work.

If the Leak Sensor3 detects the leakage, LK3 LED is lit and error message is displayed.
Figure 1. Cabinet Monitor Check
Remove cap of the reservoir.
1. For MCS, open front cover and access to the cap of the reservoir.
  
  Figure 2. MCS
2. For LCS, remove water filler cover on top of the unit to access the reservoir.
  
  Figure 3. LCS
Fill the reservoir. Check the float in the reservoir sight tube on the front of the unit to see the coolant level in the tank as you are filling. Fill the coolant so that the float reaches near the upper limit. Then, close the cap of the reservoir.

Figure 5. LCS Gauge
Restore the water filler cover on top of the unit to access the reservoir.
For LCS, read the water flow meters and check that the water flow satisfies the specification.
