Section 2 - Minimum Installation Requirements
(E-Compact ATSC Transmitters)
2.4.3 Cooling
The air conditioning system should always be operated in the "recirculation" mode, with the
room temperature being reduced without outside air coming in. For improved cooling system
performance, the air conditioner should be installed in series with the transmitter's cooling cycle.
I.e., the air conditioner's outgoing flow must be directed to the front part of Hitachi Kokusai Linear
TV transmitter.
The transmitter's installation layout should contemplate a free space around the transmitter for
higher cooling efficiency and access for maintenance. Refer to the table below for details:
Note: If the transmitter is installed in a rack, the transmitter front and rear must be entirely
unobstructed.
