Replacement Instructions for the Air Bleeder Valve HP Modular Cooling System

Shutting off the water

1. Shut off the water flowing into the MCS unit at the

facility-side shut-off valve.

2. Confirm that no water is flowing into the MCS unit.

Required tools

To complete the following steps, you will need:

• T-25 Torx driver

• Pliers

• Water hose fitting wrench (included with your original

MCS unit)

• Counter hold fitting wrench (included with your original

MCS unit)

Removing the fan unit

1. Open the rear MCS door.

NOTE: The number of horizontal brackets varies

depending on the position of the fan unit (top,

middle, or bottom).

2. Using a T-25 Torx driver, remove the four Torx screws

securing the horizontal shipping bracket to the MCS

frame.

3. Loosen the two thumbscrews on the bottom of the

fan unit.

CAUTION: The fan unit weighs 16.8 k

(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.

4. Pull the fan unit out toward you, and remove it from the

MCS unit.
