MAINTENANCE & OPERATION (continued)

Control Irrigation and Storm Run Off

•Control Irrigation: In regions were wells are used for irrigation, water quality is sometimes poor, and water spray can damage heater components. Regardless of water quality, it is important that irrigation be directed away from the heat pump.

•Prevent rain water runoff from pouring directly into the heater. The heater is designed to withstand normal rainfall, but solid streams of water from roof drip-lines may eventually damage heat pump components.

•If the heat pump resides beneath a roof edge, to promote heat pump longevity, a rain leader (gutter), or rain shield, will be necessary.

Maintain Proper Clearances Around Heater

•For maximum efficiency, proper air flow clearances around heater must be maintained.

•It is important to keep the area immediately adjacent to the heat pump clear of items such as shrubs and bushes, lawn furniture, chemicals containers, etc. These items can prevent air from circulating fully through the heater, and will result in inefficient operation or damage to the heat pump.

•In addition, do not place objects on top of the heat pump; doing so will lock the air from exiting the heater, and will result in damage to the compressor and fan motor.

•Proper clearances are also necessary in order to access the working parts of your heater. A heater that is easy to "get to," will be a heater that is easy to maintain; service and maintenance personnel will thank you for keeping the area around your heater unobstructed.

•Please see diagrams, below, for specific clearance requirements.
