Note 1: The HR-20, HR-25 and HR-30 systems can provide 84 amps, 105 amps and 125
amps respectively on each of their two 120 volt circuits as long as the circuit-to-circuit
imbalance does not exceed the maximum recommended value of 20% (See page 21 for
more information and warnings).
Note 2: The recommended PTO ratio is 1.29 : 1 (129%).
The recommended engine idle speed with this PTO is 750 RPM.
This will result in a 968 RPM pump drive input, thereby insuring 5KW
of available power at engine idle. If full output is required at idle speed, then a higher PTO
ratio must be chosen to create 1200 RPM pump drive at idle speed; however care must
be taken to prevent higher engine speeds from creating a pump speed that exceeds the
pump’s maximum speed.
