Replacement Instructions for the Water Group Controller HP Modular Cooling System

4.
Using a T-25 Torx driver, remove the four Torx screws
securing the AC transfer switch chassis to the water
group controller chassis. The transfer switch chassis
cannot be completely removed yet because the cables
are still connected.
5. Disconnect the green and yellow ground bonding wires
from the water group controller.
6. Disconnect the electrical power cables from the rear of
the AC transfer switch.
a. Disconnect the three large cables, starting from the
left and moving to the right, by inserting a small
flathead screwdriver in between the cable connection
and the latch, and pulling the cable out from the
connector.
b. Disconnect the three small cables, starting from the
left and moving to the right, by pressing the small tab
on the bottom of each small cable and pulling it out
from the connector.
After you have disconnected all of the cables, the transfer
switch chassis is free from restraint and can be removed from
the water group controller chassis.
To replace this component, see "Replacing the AC transfer
switch (on page 5)."
