Notes:
1. Maximum permitted air temperature rise; 20-30 ton (UL
— 50 F) (CSA — 60 F), 40 — 60 ton (UL/CSA — 50 F).
2. Air temperature rise = kw x 3413 ÷ (scfm x 1.085)
3. All heaters on units provide 3 increments of capacity.
4. 200 and 230 volt electric heat rooftops require dual
power supplies to the control box. All other rooftops have single power connections. See
Electrical Data Section for electrical sizing information.
