Outdoor Storage (Up to 5 Years)
NOTE
Rodents and other animals in search of warm surroundings or food, like to house inside motors. Some of them attack the insulation materials. Their access to the motor should be prevented.
Inland Dry Climate
Conditions Usually Encountered
Dust, sand, heat from the sun, and occasional rain or snow.
Requirements
If the ambient temperature exceeds 140°F (60°C), the space or structure should be enclosed but ventilated. If the ambient temperature is below 40°F (4.5°C), the space heaters, if the motor is so equipped, should be energized. Cover the motor completely to exclude dirt, dust, moisture and other foreign materials. At a bare minimum, a heavy waterproof cover should be slipped over the motor.
After the motor is covered as described, a shed of some sort should be erected to protect it from direct rain, snow and excessive direct sun heat. Proper wrapping will protect the motor from blown sand and dirt.
If the motor can be moved, it is suggested that the entire motor be encased in a strong, transparent plastic bag. Before sealing the bag, a moisture indicator should be attached to the side of the motor and several bags of silica- gel desiccant placed inside the bag around the motor. When the moisture indicator shows that the desiccant has lost its effectiveness, as by a change in color, the bag should be opened and the desiccant replaced with fresh material. Take care in placing the bags of desiccant so that none is in contact with the heater element.
When a motor cannot be sealed for effective use of a desiccant, and the relative humidity is greater than 50% or where there are large daily swings in temperature the space heaters
If the motors are not equipped with space heaters, consult the factory for proper size of external heaters to be used.
