Evaporative Cooling

Before using you cooler for the season, make sure the pads are in new condition. Replace them if

they are damaged or covered with calcium. The water pan should be wiped clean so the pump can

work at full capacity without blockage. The hoses should be checked inside the cooler to make sure

they are all connected to and from any fittings. After the cooling season has ended, the water should

be drained from the cooler to prevent rusting out of the water pan and the water supply line should be

turned off to prevent freezing. Upon winterizing, we recommend covering your cooler unit shield it

from the elements. For proper air flow and function of evaporative cooling it is recommended that a

window (bathroom for security purposes) be kept slightly open.

Helpful Hints on Air Conditioning

Draw shades on windows exposed to the sun. Sun shining through exposed windows adds

needless heat to the house. The cooling unit then has to contend with this stored heat as well as the

normal cooling load.

Keep all windows and doors closed. During the cooling excessive amounts of outside air add an

extra burden to the cooling system and waste electricity. Normal door opening and closing allows

sufficient air leakage to change all the air in the house about six times a day and is ample for ordinary

ventilation needs.

Don’t turn cooling system off. Part time cooling is usually poor economy. If the air conditioner is left

off during morning hours, the house has a chance to soak up heat from the sun. Your air conditioner

has little reserve capacity for handling this extra load of stored heat. You actually save money by

leaving your air conditioner on all the time, as the thermostat will turn the system on only when

cooling is needed.

Keep air conditioner blower on continuously. The blower gives refreshing air movement and

evens temperatures throughout the entire house. The air is constantly circulated through the filter,

thus removing dust, lint and certain pollen from the air you breathe. However, let the fan cycle with

the compressor in high humidity weather.

Avoid continuously changing the thermostat setting. When you have found the temperature you

prefer, it is best to leave the thermostat at the setting. Avoid “up and down” cooling by letting the

thermostat control the air conditioning system. If the unit is turned off wait approximately five minutes

before turning it on.

Use the kitchen exhaust fan when cooking. Turning on the exhaust fan the minute you start

cooking the fan removes excess heat, humidity and cooking odors. This keeps the hot air from the

rest of the rest of the house and lessens the cooling load.

Clean filters every three weeks and more often necessary. It is important that the filters be kept

clean, as a dirty filter hinders air flow. This will impair the operation of the unit and reduce the

effectiveness of the entire air conditioning system.

Power interruptions or lighting storms. Turn the unit off until the electrical service has been

restored or lighting ceases.
