Congratulations on the purchase of your EVAPCO air cooled 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 aer delivery. Residue le on product surfaces can cause damage that is
not covered by any warranty. All new cooling equipment and associated piping should be pre-cleaned and flushed to remove grease, oil,
dirt, debris and other suspended solids prior to operation. Any pre-cleaning chemistry should be compatible with the cooling equipment’s
materials of construction. Alkaline formulations should be avoided for systems which include galvanized materials of construction.
Closed hydronic systems connected to a dry fluid cooler should be pre-cleaned and flushed to remove debris, grease, flash rust, oil, and
other suspended solids prior to operation. EVAPCO recommends the use of inhibitor chemistry or inhibited glycol to minimize corrosion
and scale during normal operation.
Air cooled equipment is oen remotely located and periodic maintenance checks are oen 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 and maintenance intervals for unit start up, unit operation and unit shutdown. Please
note: the maintenance intervals are minimums. Maintenance should be performed more oen when operating conditions necessitate.
Become familiar with your air cooled equipment. Refer to the isometric drawings located on pages 21-23 for information on the arrange-
ment of components in your equipment.
If you should require any additional information about the installation, 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.
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.
Never operate this equipment without fan screens and access panels properly secured and in place.
Each coil in this unit ships from the factory with a nitrogen charge on the coils. Verify that the nitrogen charge is
still applied before installing unit. Release pressure in each coil before installing heat transfer fluid piping.
An optional factory provided disconnect switch may be located on 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.
Closed hydronic systems connected to either a closed-circuit cooler or dry cooler should be pre-cleaned and
flushed to remove debris, grease, flash rust, oil, and other suspended solids prior to operation. EVAPCO recom-
mends the use of inhibitor chemistry or inhibited glycol to minimize corrosion and scale during normal operation
EVAPCO requires that all external piping and fittings be externally supported, the supplied connections are not
designed to support external piping or fitting weights. Additional weight to the connections or coil in any way
could cause damage to the unit not covered under warranty.
