SPECIAL PRECAUTIONS

THE INSTALLATION AND MAINTENANCE INSTRUCTIONS
IN THIS MANUAL MUST BE FOLLOWED TO PROVIDE SAFE,
EFFICIENT AND TROUBLE-FREE OPERATION. IN ADDITION,
PARTICULAR CARE MUST BE EXERCISED REGARDING
THE SPECIAL PRECAUTIONS LISTED BELOW. FAILURE
TO PROPERLY ADDRESS THESE CRITICAL AREAS COULD
RESULT IN PROPERTY DAMAGE OR LOSS, PERSONAL
INJURY, OR DEATH. THESE INSTRUCTIONS ARE SUBJECT
TO ANY MORE RESTRICTIVE LOCAL OR NATIONAL CODES.
HAZARD INTENSITY LEVELS
1. DANGER: Indicates an imminently hazardous situation
which, if not avoided, WILL result in death or serious injury.
2. WARNING: Indicates a potentially hazardous situation
which, if not avoided, COULD result in death or serious
injury.
3. CAUTION: Indicates a potentially hazardous situation
which, if not avoided, MAY result in minor or moderate
injury.
4. IMPORTANT: Indicates a situation which, if not avoided,
MAY result in a potential safety concern.
DANGER
Units must not be installed where they may be exposed to a
potentially explosive or flammable atmosphere.
WARNING
1. Disconnect power supply before making wiring connections
to prevent electrical shock and equipment damage.
2. All appliances must be wired strictly in accordance with
wiring diagram furnished with the appliance. Any wiring
different from the wiring diagram could result in a hazard
to persons and property.
3. Any original factory wiring that requires replacement must
be replaced with wiring material having a temperature
rating of at least 105°C.
4. 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 appliance for complete appliance 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.
CAUTION
1. Do not reuse any electrical component which has been
wet. Such component must be replaced.
2. Do not operate the units within steam pressure greater
than 10 psig. Steam pressure must be 10 psig. or lower
to avoid excessive discharge air temperatures that could
cause burns or personal injury.

UNIT LOCATION

Units must not be installed where they may be xposed to a
potentially explosive or flammable atmosphere.
1. Units should not be installed in atmospheres where
corrosive fumes or sprays are present.
2. Be sure no obstructions block air intake or air discharge of
unit heater.
3. Columns, machinery, partitions, and other obstacles should
not interfere with air streams from unit heaters.
4. Unit heaters installed in a building exposed to a prevailing
wind should be located to direct a major volume of heated
air along the windward wall of the building.
5. Vertical delivery unit heaters should generally be located in
the central area of the space to be heated. Place horizontal
delivery units along the walls of the same building where
heat loss is usually greatest.
6. Arrange horizontal delivery units so they do not blow
directly at occupants.
7. When only vertical delivery units are installed, they should
be located so exposed walls are blanketed by their air
streams.
8. Mounting height is critical for optimum performance. Refer
to Mounting Height on page 4 before installation.

IMPORTANT

Start-up and adjustment procedures must be performed by a
qualified service agency.
