tion should be such that if the internal components overheat and melt / dislodge due to

of the unit on to a combustible material and cause a fire hazard. The size of openings
has been limited as per the safety requirements to prevent the above possibilities when
the unit is mounted in the recommended orientations. In order to meet the regulatory
safetyrequirements,themountinghastosatisfythefollowingrequirements:
- Mount on a non-combustible material.
- The mounting surface should be able to support the weight of the unit
- Mount horizontally on a horizontal surface - above a horizontal surface
(e.g.tabletoporashelf).
- Mount horizontally on a vertical surface – The unit can be mounted on a vertical
