NOTES:
1. Compressor motor thermally protected internally.
2. All wiring to the unit must comply with NEC and local codes.
3. Transformer is wired to 265 v lead (BRN) for 265-1-50 units. For 220/240 v
operation, disconnect BRN lead at L1 and connect ORG lead to L1. Insulate
open ends of BRN and RED leads. Transformer is energy limiting or may have
circuit breaker.
4. FP1 thermistor provides freeze protection for source water. When using anti-
freeze solutions, cut JW3 jumper.
5. Refer to or Thermostat Installation, Application and Operation Manual for con-
trol wiring to the unit. Low voltage wiring must be “Class 1” and voltage rating
equal to or greater than unit supply voltage.
