Bhp — Brake Horsepower

TXV — Thermostatic Expansion Valve

*Circuit 1 uses the lower portion of condenser coil and lower portion of evapora- tor coils; and Circuit 2 uses the upper portion of both coils.

†Rollout switch is manual reset.

**The 579F300 units requires 2-in. industrial-grade filters capable of handling face velocities of up to 625 ft/min (such as American Air Filter no. 5700 or equivalent).

NOTE: The 579F units have a low-pressure switch (standard) located on the suc- tion side.
