Cooler Installation
Installation with the cooler in the cooler housing:
1. Bolt in lifting eyes at all four corners of the cooler housing. Attach a chain to
the lifting eyes, and set the cooler hood on top of the drip tray assembly.
See Figure 6.
2. Install the fasteners that attach the cooler to the drip tray assembly. (If re
quired). Put Loctite 242 on the bolt threads. Tighten the fasteners to the torque
value in Table 2.
3.
Install the fasteners that attach the cooler hood to the generator. See Figure 5.
Tighten the fasteners to the torque value in Table 2.
4. Reconnect the cooler RTD’s and leak detector.
5. Reconnect the water input and output lines to the cooler.
Installing the cooler into the cooler housing:
1. Using a hoist and strap, lift the cooler and line it up with the cooler hood.
2. Slide the cooler into the hood. Insert the fasteners to hold the cooler to the
cooler hood.
3.
Attach the fasteners on the non inlet/outlet side and attach the cooler cover.
4. Tighten all fasteners to the torque value in Table 2.
5. Reconnect the cooler RTD’s and leak detector.
6. Reconnect the water input and output lines to the cooler.
Checking and replacing the cooler anodes (if present)
Remove the anode plugs and O-rings. When the zinc anodes on an anode plug have
dissolved to one-third their original size, remove them, thread on another set of zinc
anodes, and reinstall the anode plug and O-ring. Tighten the anode plug to the torque
value specifi ed in Table 2.
In the examples shown, the drip tray
is built into the cooler cover, and the
cooler does no bolt to it. Refer to the
specifi c drawings for you generator.
Use safe lifting practices to avoid dam-
age to the cooler or injury to personnel.

ings or the cooler plate
