Installation Drawings Summary
Detailed installation drawings are provided for the 48 kW and 60/80 kW models. These drawings illustrate overall dimensions, component locations (e.g., air intake, exhaust, oil fill, battery, control panel access), and mounting details. Key notes cover concrete pad requirements (e.g., minimum size and offset), service access, ventilation requirements (fresh air intake, discharge air), and compliance with applicable NFPA standards. Specific dimensions for various views (top, side, rear) are provided in millimeters and inches.
