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.
It is important to establish a regular maintenance program and
be sure that the program is followed.
A clean and properly serviced unit will provide a long service
life and operate at peak efficiency.
If you should require any additional information about the
operation or maintenance of this equipment, you can consult
Bulletin 116-E or contact your local EVAPCO representative.

Safety Precautions / Remaining Risks
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.
WARNING: Evaporative cooling equipment is considered as “Partly completed machinery”. “Partly completed machinery” is
a totality which almost forms a machinery but in itself cannot fulfil any particular function. The considered cooling
equipment is missing the components to safely connect it to the source of energy and motion in a controlled way.
The considered cooling equipment is custom made but is not designed to address the specific needs and safety
measures for a specific application. Each application requires a unique designed and integrated operational,
control and safety strategy that links all components of the installation and eventually a back-up system in a safe
and controlled way.
WARNING: This equipment should never be operated without fan screens and access doors properly secured, locked and
in place.
WARNING: For assembling or disassembling the unit or unit sections, please follow the rigging instructions or the
instructions on the yellow labels on the individual unit sections.
WARNING: During maintenance operations, the worker must use adequate personal protection equipment (PPE - A
minimum, but not limited list of PPE are safety shoes, glasses, gloves, respiration protection, helmet) as
prescribed by local authorities.
WARNING: For any exceptional, non routine work to be carried out, protection and adequate safety measures should be
considered and a Last Minute Risks Assessment (LMRA) must be made by an authorized person in accordance
with safety requirements of the country.
WARNING: A lock-out / tag-out procedure, integrated with the Process Control System, must be foreseen by the
customer. 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.
WARNING: 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. For any exceptional, non routine work to be carried out on top of the
unit, use ladders, PPE and adequate safety measures against the risk of a fall, in accordance with safety
requirements of the country in question.
WARNING: The recirculating water system may contain chemicals or biological contaminants including Legionella
Pneumophila, which could be harmful if inhaled or ingested. Direct exposure to the discharge airstream
and the associated drift generated during operation of the water distribution system and/or fans,
or mists generated while cleaning components of the water system, require respiratory protection
equipment approved for such use by governmental occupational safety and health authorities.
WARNING: To avoid water and air contamination as a result of biological fouling, the cooling equipment must be
maintained in accordance, but not limited to the operating and maintenance instructions. All local
legislation related to evaporative cooling equipment must be respected.
WARNING: Accessories like platform and ladders are optional. In case these options are not taken in consideration, the
customer must design the installation to comply with local safety and access requirements and legislation.
WARNING: Sound reducing options are available. In case these options are not taken in consideration, the customer
must design the installation to comply with local sound requirements and legislation.
WARNING: 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.)
