LEGEND AND NOTES FOR FIG. 1-9
LEGEND
NOTES:
1. Factory wiring is in accordance with the National Electrical
Codes. Any field modifications or additions must be in compli-
ance with all applicable codes.
2. Use 75° C min wire for field power supply, use copper wires for
all units.
3. All circuit breakers “Must Trip Amps” are equal to or less than
156% RLA.
4. Compressor and fan motors are thermally protected three
phase motors protected against primary single phase conditions.
5. Red jumper wire must be added between R, W1, and W2 for
space temperature sensor and all VAV units with heat and tem-
porarily during service-test mode when the heaters need to
operate.
