*Maximum number of stages using accessory low-ambient kit or head pressure control device and low-ambient kit.

NOTE: Heaters are rated at 240, 480, and 600 v. Use the Multiplication Factors table below to determine heater capacity for your particular voltage.

NOTE: The following equation converts kW of heat energy to Btuh:	EXAMPLE: 34 kW (at 230 v) heater on 208 v
kW x 3.413 = Btuh.	= 34.0 (.751 mult factor)
	= 25.5 kW capacity at 208 v.
