Replacement Instructions for the Air Bleeder Valve HP Modular Cooling System

Replacing the fan unit
1. Align the fan unit to the sliding rails.
CAUTION: The fan unit weighs 16.8 kg (37 lb).
Use extra caution when removing and replacing the
top fan unit because it might be higher than your
shoulders and is heavy and awkward to lift.
2. Slide the fan unit onto the sliding rails inside the
MCS unit.
3. Tighten the two thumbscrews to secure the fan unit to the
MCS frame.
NOTE: The number of horizontal brackets varies
depending on the position of the fan unit (top,
middle, or bottom).
4. Using a T-25 Torx driver, secure the horizontal shipping
bracket to the MCS unit by inserting four Torx screws.
5. Complete the operation checklist.
Operation checklist
1. If water was disconnected, restore water flow to the
MCS unit at the facility-side valve.
2. Clear all old logs from the web interface to ensure that
any additional alarms are current.
3. Confirm that no additional warning or alarm messages
have been detected by looking at the operator display.
Returning the failed component
Instructions are provided on the return label supplied with the
