WARNING
To ConvertMultiply ByTo Obtain
1.When servicing or repairing this equipment, use only
factory-approved service replacement parts. A complete
replacement parts list may be obtained by contacting
Modine Manufacturing Company. Refer to the rating plate
on the unit for complete unit model number, serial number,
and company address. Any substitution of parts or controls
not approved by the factory will be at the owner’s risk.
2.Disconnect power supply before making wiring connections to
prevent electrical shock and equipment damage.
3.Do not submerse the pump motor in water. The
evaporative cooler pump motor is not submersible.
CAUTION
Any original factory wiring that requires replacement must be
replaced with wiring material having a temperature rating of
at least 105°C.
important
1. To prevent heat exchanger failure, do not operate the
evaporative cooling unit in air streams with temperatures
below 40°F. Operating the unit in temperatures less than
40°F will cause icing. Normally ice will not harm the
media, but it can block the airflow and possibly crack the
plumbing.
2. Start-up and adjustment procedures should be performed by a qualified service agency.
3. The proper media direction must have the 45° flutes slope
down toward the air entering side. The 15° flutes must
slope down toward the air leaving side. See Figure 8.2 for
media direction.
4.To check most of the Possible Remedies in the
troubleshooting guide listed in Table 9.1, refer to the
applicable sections of the manual.

UNIT LOCATION RECOMMENDATIONS
1. When the unit is equipped with an evaporative cooler, the
module is factory installed and wired. Refer to Literature
5-572 or AIR5-572 - Installation and Service Manual for
recommendations.
2. When locating the unit, consider general space and cooling
requirements and availability of water supply/drain and
electrical supply.
3. Be sure the structural support at the unit location is adequate
to support the weight of the unit.
UNIT LIFTING
When the unit is equipped with an evaporative cooler, the
module is factory installed and wired. Four 3/4" holes at the
extended ends of the unit mounting channels are supplied to
facilitate lifting the unit. Refer to Literature 5-572 or AIR5-572 –
Installation and Service Manual for recommendations.
