1The heat recovery and efficiency values are those for rated output in standard atmospheric conditions.
2The operating sound levels are maximum values measured in 4 directions at a point 1m from the side of the unit and 1.2m above the ground in an anechoic room simulation. The sound levels during actual operation are usually higher than the simulated values due to ambient noise and echoes.
3The values for the external dimensions do not include piping, piping connections, or protruding parts.
4The amount of fuel consumption is based on lower calorific values.
*1 Power consumption is included
*2 Max of +5%; 25.5l/min
*3 Tolerance +5% is not included

When the unit is installed indoors, a syphon (option) should be installed.
If the back pressure of the exhaust-piping extension exceeds 500Pa, use a long syphon and make the height of the base from F.L. to 250mm or more.

Notes:
1For use of box-out L-type/LA-type bolt.
When laying the concrete for the base, provide a box-out for fixing the anchor bolts, fix the anchor bolts and then secure them in the concrete.
2It is sometimes necessary to change the thickness of the base depending on the foundation strength, so carry out the work after consulting construction engineers.
3Earthquake-resistance strength: Horizontal seismic coefficient of 0.6 (Numeric values with * show the dimensions in the case of a horizontal seismic coefficient 1.0).
4When using a smaller base, join the base and the structure with reinforcing bars.

Notes
1.When surrounding the unit with soundproof walls, attach openings (louvres or the like) to the bottom of the soundproof walls. (To prevent the short circuits of radiating air).
2.Decide installation space after consideration of the piping space.
3.If the distance of retention is specified by local-government fire prevention ordinances and enforcement regulations, secure the installation space according to these regulations.
4.Give consideration not to cause problems for neighbouring houses due to operating noise, radiating air, or hot ventilation air.
5.Depending on the situation, the site may be filled with radiating air and this has an effect on performance. Prevent the short circuits with the optional wind direction boards, etc.

Electrical output is based on output at the generator terminals at a power factor of 0.95. Energy quantities subject to reduction when modulating in response to external conditions. We reserve the right to alter the Engine Type, at any time, to meet the system specifications. Performance figures are subject to original Engine manufacturer’s declared performance, tolerances and test conditions. Output figures are based on operation at ISO3046 conditions with the exception of the exhaust output, temperature stated above. Technical Datasheets are subject to change, without notice, due to our commitment to on-going product improvement.
