Special Design Requests
Modine Manufacturing Company will sometimes build units
with special features as requested by the customer. This
manual only covers standard features and does not include any
changes made for special feature requests by the customer.
Units built with special features are noted with an SPO (Special
Product Order) Number on the Serial Plate
Storage Prior to Installation
If the unit is stored outside prior to installation, the unit should
be covered.
IMPoRtANt
eventually causing the drain pan to fill. To prevent
damage to the building or unit, a drain pan float switch
is included as standard and will disable the unit if the
maximum condensate level is reached.
3. To prevent premature heat exchanger failure, the input
to the appliance, as indicated on the serial plate, must
not exceed the rated input by more than 5%.
4. To prevent premature heat exchanger failure, check to
be sure the blower has been set to deliver the proper
airflow for the application. Refer to page 17 for Blower
Adjustments.
5. Start-up and adjustment procedures must be performed
by a qualified service agency.
6. All scroll compressors requires the correct supply power
phase rotation. Phase reversal may result in compressor
failure not covered under warranty. Refer to the Start-Up
Procedure section.
7. All refrigeration checks must be made by a qualified
R-410A refrigeration technician.
8. Do not release refrigerant to the atmosphere. When
adding or removing refrigerant, all national, state/
province, and local laws must be followed.
9. On units with the electric preheat option, to prevent
premature heat exchanger failure, check to be sure the
blower has been set to deliver the proper airflow for the
application. Refer to page 17 for Blower Adjustments.
10. The exhaust fan is not designed for high temperature
or smoke control exhaust applications. Exhaust air
temperature must not exceed 104°F. Operating the
exhaust fan above 104°F will result in failure of the
exhaust fan.
