Introduction; Safety Precautions; Terminology - EVAPCO ESW Series Operation And Maintenance Instruction

Introduction

Congratulations on the purchase of your EVAPCO evaporative cooling unit. EVAPCO equipment is constructed of the highest quality
materials and designed to provide years of reliable service when properly maintained.
Thoroughly clean road salt, dirt and debris from unit immediately after delivery. Residue left on product surfaces can cause damage that is
not covered by any warranty.
Evaporative cooling equipment is often remotely located and periodic maintenance checks are often overlooked. It is important to
establish a regular maintenance program and be sure that the program is followed. This bulletin should be used as a guide to establish a
program. A clean and properly serviced unit will provide a long service life and operate at peak efficiency.
This bulletin includes recommended maintenance services for unit start up, unit operation and unit shutdown and the frequency of each.
Please note: the recommendations of frequency of service are minimums. Services should be performed more often when operating
conditions necessitate.
Become familiar with your evaporative cooling equipment. Refer to the isometric drawings located on pages 31-52 for information on the
arrangement of components in your equipment.
If you should require any additional information about the operation or maintenance of this equipment, contact your local EVAPCO
representative. You may also visit www.evapco.com or www.mrgoodtower.com for more information.

Safety Precautions

Qualified personnel should use proper care, procedures and tools when operating, maintaining or repairing this equipment in order to
prevent personal injury and/or property damage. The warnings listed below are to be used as guidelines only.
This equipment should never be operated without fan screens and access doors properly secured and in place.
A lockable disconnect switch should be located within sight of the unit for each fan motor associated with this
equipment. Before performing any type of service or inspection of the unit make certain that all power has been
disconnected and locked in the "OFF" position.
The top horizontal surface of any unit is not intended to be used as a working platform. No routine service work is
required from this area.
Building water systems receive potable and non-potable water from either a public or private entity for their water
supply. This water supply for the building water system can contain various waterborne pathogens, including
Legionella bacteria, which can cause or contribute to various illnesses if aspirated, ingested or inhaled. Since
evaporative cooling equipment uses the same building water, there is some potential that these pathogens might
propagate in the equipment. Therefore, careful consideration should be undertaken with respect to equipment
location and the implementation of effective water management, inspection and cleaning protocols. (See Control of
Biological Contaminants in these Operation and Maintenance Instructions.)
