Do not perform any service on or near the fans, motors, or drives or inside the unit without first ensuring that the fans and pumps are disconnected, locked out, and tagged out.
Check to ensure the fan motor bearings are set well to prevent motor overload.
Openings and/or submerged obstructions may exist in the bottom of the cold water basin. Be careful when walking inside this equipment.
The top horizontal surface of the unit is not intended for use as a walking surface or working platform. If access to the top of the unit is desired, the purchaser/end-user is cautioned to use appropriate means complying with applicable safety standards of governmental authorities.
Spray pipes are not designed to support the weight of a person or to be used as a storage or work surface for any equipment or tools. Use of these as walking, working or storage surfaces may result in injury to personnel or damage to equipment. Units with drift eliminators should not be covered with a plastic tarpaulin.
Personnel exposed directly to the discharge airstream and the associated drift/mists, generated during operation of the water distribution system and/or fans, or mists produced by high pressure water jets or compressed air (if used to clean components of the recirculating water system), must wear respiratory protection equipment approved for such use by governmental occupational safety and health authorities.
The basin heater is not designed to prevent icing during unit operation. Do not operate the basin heater for extended periods of time. A low liquid level condition could occur, and the system will not shut off which could result in damage to the heater and unit.
Please refer to the Limitation of Warranties in the submittal packet applicable to and in effect at the time of the sale/purchase of these products. Described in this manual are the recommended services for start-up, operation, and shutdown, and the approximate frequency of each.
SPL units are typically installed immediately after shipment and many operate year round. However, if the unit is to be stored for a prolonged period of time either before or after installation, certain precautions should be observed. For instance, covering the unit with a clear plastic tarpaulin during storage can trap heat inside the unit, potentially causing damage to the fill and other plastic components. If the unit must be covered during storage, an opaque, reflective tarp should be used.
All electrical, mechanical, and rotating machinery are potential hazards, particularly for those not familiar with their design, construction, and operation. Therefore, use appropriate lockout procedures. Adequate safeguards (including the use of protective enclosures where necessary) should be taken with this equipment both to safeguard the public from injury and to prevent damage to the equipment, its associated system, and the premises.
Do not use oils containing detergents for bearing lubrication. Detergent oils will remove the graphite in the bearing sleeve and cause bearing failure. Also, do not disturb bearing alignment by tightening the bearing cap adjustment on a new unit as it is torque- adjusted at the factory.
This equipment should never be operated without all fan screens, access panels, and access doors in place. For the protection of authorized service and maintenance personnel, install a lockable disconnect switch located within sight of the unit on each fan and pump motor associated with this equipment according to the practical situation.
Mechanical and operational methods must be employed to protect these products against damage and/or reduced effectiveness due to possible freeze-up.
Never use chloride or chlorine based solvents such as bleach or muriatic (hydrochloric) acid to clean stainless steel. It is important to rinse the surface with warm water and wipe with a dry cloth after cleaning.
General Maintenance Information
The services required to maintain a piece of evaporative cooling equipment are primarily a function of the quality of the air and water in the locality of the installation.
AIR: The most harmful atmospheric conditions are those with unusual quantities of industrial smoke, chemical fumes, salt or heavy dust. Such airborne impurities are carried into the equipment and absorbed by the recirculating water to form a corrosive solution.
WATER: The most harmful conditions develop as water evaporates from the equipment, leaving behind the dissolved solids originally contained in the make-up water. These dissolved solids may be either alkaline or acidic and, as they are concentrated in the circulating water, can produce scaling or accelerate corrosion.
lThe extent of impurities in the air and water determines the frequency of most maintenance services and also governs the extent of water treatment which can vary from a simple continuous bleed and biological control to a sophisticated treatment system.
