5. Installation Requirements
(1) Selection of a place which does not receive direct sun-
light or radiation from hot substances
If such a place cannot be found, a roof or cover should
be prepared for protection.
(2) Avoidance of a place under heavy vibration
(3) Selection of a place where atmospheric air is clean
