Drive Cooling Loop Hose Kit
What This Kit Includes
• Two hoses
• Two drive side couplings
• Two heat exchanger side couplings
• Two male 1 inch-to-1 inch elbows 37°
(only included with 20L-GHxx-A2 hose kits)
Tools That You Need
• Liquid soap
• Tightening wrench
• Backup wrench
Step 1: Attaching a 
Coupling to a Hose
A. Lubricate the inside of the hose end with a small amount of liquid soap.
B. Set the coupling down on a solid surface and push the hose onto the
coupling — in one firm push — until the hose end is flush against the 
plastic bushing. Stopping before the hose is fully on may make it 
difficult to push the hose completely onto the coupling. 
Step 2: Connecting an 
Elbow to a Pipe Nipple
(only 20L-GHxx-A2 Kits)
To use a 13 kW capacity PowerFlex 700L Liquid-to-Liquid Heat Exchanger 
(catalog number 20L-LL13K-P75A) with a PowerFlex 700L Frame 3A 
drive, the 20L-GHxx-A2 hose kit comes with 1-inch elbows that must be 
exchanged for the elbows provided with the heat exchanger.
A. Use a 1-3/8 inch or adjustable wrench to remove the 1 inch-to-3/4 inch
reducers and 3/4 inch elbows already assembled on the heat exchanger at 
the "TO DRIVE INLET" and "FROM DRIVE OUTLET" connections. 
(There is no need to use a backup wrnech on the pipe nipple.)
