Prior to assembly, inspect all components for damage. Report any damage to the shipping company. Check the packing list in the back of this manual

to be sure all parts are included.

Select a mounting location in accordance with the guidelines in the IM1000 Installation Manual. The generator set must typically be mounted on a

rigid, at surface above a strong structure, such as the vessel’s stringers, to minimize vibration transference to the hull.

Note that the generator set is designed for single side service. When viewed from the rear, the left hand side is the service side and should be exposed

for easy maintenance access.

Install the generator set in the vessel as near to a level attitude as possible. Ensure that the enclosure’s right hand side and rear are at the

recommended distances (6 inch recommended, 4 inch minimum.) from the vessel’s bulkheads.

Note: The Generator set may still possess original factory lifting points. These lifting points will need to be loosened and rotated down, below the highest

point of the engine. Be sure to tighten these bolts before installing generator set.

AVOID POSITIONING THE ENCLOSURE INTO CORNERS WITH OVERHEAD BLOCKED TO REDUCE CHANCE OF INTAKE/EXHAUST AIR

RECIRCULATION OUTSIDE THE SHIELD.

STEP 12

CONNECT GENERATOR SET TO THE VESSEL. SEE PICTURE BELOW AND LEGEND.

a. Connect the exhaust elbow of the diesel engine to the exhaust system of the vessel. Pass the three inch exhaust hose through the opening provided in the

right side of the rear panel.

b. Connect the sea water pump to the vessel’s water inlet. Pass a 3/4” ID hose from the vessel’s sea water strainer, through the bottom hole on the right side

of the rear panel to the sea water pump inlet tting.

c. Connect the vessel’s fuel supply and fuel return to the generator set using Coast Guard approved rubber fuel hose. Fuel connections are 5/16-37T JIC inlet

and 1/4-37T JIC outlet located at the fuel manifold on the base frame of the generator set’s left hand side, through the bottom hole in the left side of the rear

panel.

d. Connect the DC control panel harness to the genset engine harness plug through the middle hole on the rear panel’s left lower side.

e. Connect the 12 volt battery leads to the generator set using the top slot on the right side of the rear panel.

f. Connect the AC output leads from the generator junction box to the vessel’s power distribution panel. Pass the two leads through the top slot on the left side

of the panel.
