Prior to assembly, inspect all components for damage. Report any damage to the shipping company. Check the packing list to be sure all parts are included.
Select a mounting location in accordance with the guidelines in the IM1000 Installation Manual (supplied with the generator set). The generator set must typically be mounted on a rigid, flat surface above a strong structure, such as the vessel’s stringers, to minimize vibration transference to the hull. CAUTION: THE BASEBOARD
IS A NON-STRUCTURAL MATERIAL AND MUST BE FULLY SUPPORTED TO MINIMIZE FLEX.
Note that the generator set is designed for single side service. When viewed from
Install the base board (item 1) in the vessel in as near a level attitude as possible. Observe the arrow symbol on the board’s topside surface. This indicates the top and forward end orientation of the genset / soundshield. Make sure arrow is correctly positioned or the unit will not mount correctly within the shield.
Install toe bracket (item 15) to each corner of the base board with screws (item 14) into pre-drilled holes. See figure 1.
Note that there are pre-drilled “through” holes on each side of the baseboard. Use these holes as guides to drill into the supporting substructure for through-bolting.

Place the generator set onto the baseboard. Note that there are lines present on the base board at the front and the sides; position the genset base pan to conform with these alignment markings.
Install the hold down clips to the pre-drilled through holes along both sides of the genset base pan. Use 3/8” or 9 mm bolts of appropriate length to secure the genset and baseboard to the underlying structure. Loosen lifting eye mounting bolt and tip
