About this task

Procedure

After the system runs for about 30 minutes, check each of the paper towels for evidence of a coolant leak.

Note: A coolant leak shows as blue. Normal condensation is clear.

Notice

Do NOT turn off the Variable Frequency Drive (VFD) from the circuit breaker unless the VFD is stopped (display shows dashed lines '---').

Stop the VFD from the HEC control panel before powering down the circuit breaker.

If a leak is found, turn off the pumps at the bottom of the HEC. For each tank, hold down the keys (shown in Table 1) simultaneously on the HEC control panel. This sequence toggles the pumps on and off.
