Operation and Maintenance Instructions

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.
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.
