If the base isunstable, reinforce with a concrete base.• The hot water module must be anchored on a levelsurface. Use a level to check after installation.• If the hot water module is installed near a roomwhere noise is a problem, using an anti-vibrationstand on the base of the unit is recommended.1. Fix the hot water module with M10 anchor bolts at 4positions. 15 mm projection is appropriate for ananchor bolt.(Unit: mm)1527-EN 28-EN
