Description
The Hessaire® Evaporative Cooler is a natural way to condition the atmosphere. It cools by combining water evaporation with aire movement, through carefully designed and manufactured equipment, providing maximum efficiency and safety. This air conditioning system, in addition to being economical, gives more benefits than other air conditioning systems for homes and businesses. The system does not use refrigerants or compressors; it cools by simply moving air through moist filters. Air temperature drops when a liquid, in this case water, transforms into gas. Humidity is not perceived, since the air in the room is renewed approximately every two minutes, providing a comfortable cooling effect. Continuous air circulation is a vital aspect of the cooling process in this equipment, and gives it a distinct advantage over air conditioning by refrigeration.

5. Place the supports into their original position once maintenance has been performed.

NOTE: Never operate the unit without these parts in place. Doing this could generate an overload and damage the motor.

BELT ADJUSTMENT
The adjustable belt and pulleys are factory set. Any alteration to the air flow system should be done by an authorized technician. Before any adjustment is made, unplug the cooling system. The appropiate belt tension and alignment is an important factor for the effcient operation of the unit. Do not adjust the belt tension by changing the pulleys diameter. Adjust the brackets that hold the motor to the motor base only. Due to wear and use, the belt tends to loosen, therefore, chech for proper tension during maintenance. To adjust the belt tension, loosen the screws on the motor brackets (use a 7/16 inch or an adjustable wrench). Once loosened the motor can then be repositioned to apply more tension to the belt. Belt tension should be adjusted to allow for 1.2 cm (1/2”) to 2 cm (3/4”) of fiexing on each side of pulley. Once the required belt tension is reached, retighten set screws on the bracket. Align the belt in vertical position, and check the amperage of the motor.

PULLEY ADJUSTMENT
Incorrect pulley adjustment and alignment will affect performance by reducing airflow raising amperage or causing the motor to overheat.

Warning: Before make any adjustments deenergize your equipment to avoid personal risks.

To adjust pulleys loosen the set screw and align the motor pulley with the turbine pulley vertically by moving outwards or inwards on the shaft of the motor. A straight edge should be used when aligning pulleys. After adjustment retighten set screws. Turn the turbine pulley manually to make sure it misses the turbine box and that the motor pulley does not make contact with the motor. Motor maintenance

Warning: Always deenergize your cooler before working near or in the motor.

1. The motor can require periodical maintenance to avoid overheating due to dust accumulation on the windings and frame.
2. Lubricate the motor annually after fisrt year of use to extend bearings life.
3. Add 15 to 20 oil drops for electric motor or SAE grade 10, and turn the shaft.

Lubricating bearings
Always deenergize your cooler before any maintenance.

1. Add 6 drops of lithium oil or grease with lithium base.
2. Do this maintenance two times per year.
