Chapter 5. Maintaining the heat exchanger

This chapter provides instructions for maintaining the heat exchanger.

Attention:

1. Because of the size and weight of the heat exchanger, three trained persons

are required to install or remove the heat exchanger.

2. You must remove the power from the rack and all components before you

connect or disconnect the water supply lines and drain or fill the heat
exchanger.

The following illustration shows the locations of components on the heat exchanger.

Note:

When you perform procedures on the heat exchanger, you might want to
place some water-absorbent material beneath the door assembly.

coupling (Female)

Return manifold
coupling (Male)
