Model Number Description
Digits 1, 2, 3 — Unit Configuration
EXW = Water to Water Heat Pump
Digit 4 — Development Sequence
E = R-410A
Digits 5, 6, 7 — Nominal Size (Tons)
060 = 5 Tons
120 = 10 Tons
240 = 20 Tons
Digit 8 — Voltage (Volts/Hz/Phase)
1 = 208/60/1
2 = 230/60/1
3 = 208/60/3
4 = 460/60/3
5 = 575/60/3

Note:
Heat exchanger for the load side is
copper-water coil only.
7 = Insulated Copper Water Coil/Suction
Line
8 = Insulated Cupro-Ni Water Coil/
Suction Line
Note:
Insulated heat exchanger is
recommended when EWT<60°F.

Digit 12 — Open Digit
Digit 13 — Freeze Protection (Source
Side)
A = 20°F (For Glycol Loop)
B = 35°F (For Water Loop)
Note:
The load side will have a 35°F
freeze protection.
Digit 14 — Open Digit
Digit 15 — Open Digit
