INSTALLATION SERVICE MANUAL

OUTDOOR ROOFTOP EVAPORATIVE COOLING UNITS

*Unit Type (EV) - Capacity (CA) - (10-40)

Evaporative Cooling systems meet a wide range of heating and ventilating requirements. The Evaporative Cooler may be purchased as an individual unit in four sizes from 800 CFM to 8500 CFM (0.4 to 4.0 m3/s) or, it can be combined with Rooftop Packaged Units (Natural or Power Vented), Air Handlers, or Make-up Air Handlers. In any combination, the Evaporative Cooler will replace the need for 100% Outside Air Inlet Hood.

Evaporative Cooling is the simplest and most-cost effective cooling method without the use of mechanical refrigeration.

FPO

ATTENTION: Read This manual IIEVC, manuals RISM* and RBM*, submittal/data sheets, and all labels attached to the unit carefully before attempting to install, operate, or service the Evaporative Cooling Unit! Retain this manual for future reference.

Maintain water in sumps by proper microbicidal water treatment to minimize the risks of illness caused by Legionella Pneumophila (the bacteria that causes Legionnaire's Disease) and other bacteria. Refer to local codes regar ding any additional treatment or restrictions regarding water supplies and usage.

The following terms are used throughout this manual, in addition to the other requirements, to bring attention to the presence of potential hazards or to important information concerning the product:

Indicates an imminently hazardous situation which, if not avoided, will result in death, serious injury or substantial property damage.

Indicates an imminently hazardous situation which, if not avoided, could result in death, serious injury or substantial property damage.

Indicates an imminently hazardous situation which, if not av oided, ma y result in minor injury or property damage.

NOTICE: Used to notify of special instructions on installation, operation, or maintenance which are important to equipment but not related to personal injury.

Failure to comply with the General Safety Information may result in extensive property damage, severe personal injury, or death.

GENERAL SAFETY INFORMATION

Unless otherwise speciﬁ ed, the following conv ersions may be used for calculating SI/metric unit measurements: 1 lb. = 0.453 kg 1 cubic foot = 0.028m

1000 Btu per hour = 0.293 kW 1 foot = 0.305 m 1 inch water column = 0.249 kPa 1 inch = 25.4 mm 1 gallon = 3.785 L 1 psig = 6.894 kPa 1000 BTU/cu. ft. = 37.5 MJ/m

1liter/second = CFM x 0.472 meter/second = FPM ÷ 196.8

– 2 –

Disconnect all power before installing or servicing the unit. If power disconnect is out of sight, lock it in the open position and ta g it to prevent unexpected application of power. Failure to do so could result in fatal electrical shock or severe personal injury.

Do not alter the unit in any way, or damage to the unit and/or severe personal injury or death may occur.

Do not depend on a thermostat or other switch as a sole means of disconnecting power when installing or servicing unit. Always disconnect power at the main circuit breaker as described above. Failure to do so could result in fatal electrical shock.

CELdek® EVAPORATIVE MEDIA

The Evaporative Cooler utilizes high efﬁ ciency CELdek® media. CELdek® is made from a special cellulose paper, impregnated with insoluble antirot salts and rigidifying saturants. The cross ﬂ uted design of the pads induces highly-turbulent mixing of air and water for optimum heat and moisture transfer. The evaporative coolers are available with standard 8 or optional 12 inch media which produce high efﬁ ciency and high face velocities, along with a 2" distribution pad to disperse the water evenly over the pads.
