INSTALLATION SPACE
Installation Clearance Recommendations
Notes
1. Recommended clearance for service access is 1000mm on sides, 1250mm above, 1000mm at
front and 1500mm at rear (pipework connections end) although 1000mm is acceptable.
2. Consideration must be given on installation design as to whether acoustic treatment may be
required to fans etc. which may add height to the design although this is site specific.
3. Anti-vibration mounts are shown hidden as they may not be required on certain sites and are
removable for installation.
