Location. Temperate grasslands are located north of the Tropic of Cancer (23.5 degrees North) and south of the Tropic of Capricorn (23.5 degrees South).The major temperate grasslands include the veldts of Africa, the pampas of South America, the steppes of Eurasia, and the plains of North America.limate. Temperate grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer.
In summary, certain conditions can force a heat pump into a defrost cycle (or cooling cycle) where the fan in the outdoor coil is stopped, the indoor fan is stopped or electric heat is turned on, the frost melts and is removed from the outdoor coils.
The vibration from the wobbling fan blade will be transmitted to the water pump bearing which will cause it to wear out quickly. On the other side of the coin, a worn water pump bearing will cause the bearing in the fan clutch to wear out (again, due to the transmitted vibrations). If this water pump is replaced without replacing the fan clutch, then the worn fan clutch will cause the new water pump to fail.
