Code (NEC latest edition).
Location of the applicable electric ser-
vice entrance for HIGH (line voltage)
may be found on the unit submittal at
the front of this manual (pages 7
through 9).
The high voltage connection is made
at the 1TB1 terminal block for the 20-
ton equipment, and at 1K1 for the 2-
