2.2.8. Electrical Requirements
The CMA-180 comes standard factory, wired for 3-phase operation. Check the electrical data plate to confirm this. If the account requires 1 phase, refer to “Electrical Requirements”, Section 1-A, for proper wiring instruction for conversion. Also check the wiring diagram to properly wire the terminal power block, tank heater, and booster heater for 1 phase (or 1B diagram below).
SINGLE PHASE POWER
NOTE: 80 amp service is required when CMA-180 is wired for single-phase with the booster heater. See “Electrical Requirements” section for DUAL 1-phase power supply. Circuit breaker requirement (1) 50 amp & 30 amp.
