by resetting standard controls.
2. Operation below 25°F requires the Optional Low Ambient Kit
(Minimum recommended operating temperature is 0°F).
3. Operation above 115°F requires Optional High Ambient Kit (Maxi-

4. The evaporator is protected against freeze-up to 20°F with an
electrical heater cable standard.
