3.4 VENTILATION
3.4.1 MAINFRAME SH-1/2/3/4-BM
The ambient temperature during operation must not fall below + 5 °C or exceed
+ 35 °C (41 °F to 95 °F). Optimum operation is ensured at an ambient temperature
of 20 °C.
For ventilation of the mainframe, 3 fans are provided in the upper part. These blow-
ers serve to support air circulation in the unit and to lead the heated air into the
room. The air supply is made from the front and from the bottom. Fans blow the
heated air into the rear part of the cabinet.
In order to ensure continuous air circulation, make sure that the air slots in
the bottom part of the unit are not covered when mounting the mainframe.
Exhaust air exits from the rear at top
Air intake (both sides and front)
Note: The door is an integral part of the cooling airflow design.
For proper cooling keep the door closed during normal
operation.
Ensure that the air filter fitted to the SH-1/2/3/4-BM mainframe front door is clea-
ned periodically with a vacuum cleaner to ensure the adequate cooling. The color
of the filter (normally white) can be used as a guide to their condition.
