Notes:
1. Magnetic contactors are standard.
2. Units with electric heat are available with or without door interlocking disconnect switch.
3. Units with electric heat are available with or without line fuses.
4. Units with electric heat must not be run below the minimum cfm listed. Refer to the General Data section for more information.
5. Electric heat is balanced staging: 1 stage = 100 percent, 2 stages = 50 percent/50 percent.
