SPECIAL PRECAUTIONS
2 1-500.3
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 PROPERY 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
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
the 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. Ensure that the supply voltage to the appliance, as
indicated on the serial plate, is not 5% greater than the
rated voltage.
5. When servicing or repairing of 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 model and 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. All literature shipped with this unit should be kept for
future use for servicing or service diagnostics. Leave
manual with the owner. Do not discard any literature
shipped with this unit.
2. Consult piping and electrical instructions in this manual
before final installation.
CAUTION
3. Units are designed for use in heating applications with
ambient temperatures between 40°F and 100°F.
Heaters should not be used in applications where the
heated space temperature is below 40°F unless a glycol
anti-freeze solution has been added.
4. Units not approved for use in potable water systems.
5. Do not install units below 7' measured from the bottom
of the unit to the floor in commercial applications (unless
unit is properly guarded to provide user protection from
moving parts) and 5' measured from the bottom of the
unit to the floor in residential applications.
6. Do not reuse any mechanical or electrical components
which have been wet. Replace defective components.
7. Do not operate the unit with steam. The coil is not
designed for steam condensate removal which can
damage the unit.
8. Ensure the supply voltage to the appliance, as indicated
on the serial plate, is not 5% less than the rated voltage.
IMPORTANT
1. Start-up and adjustment procedures should be
performed by a qualified service agency.
2. Be sure no obstructions block air intake and discharge
of unit heaters. Do not attach ductwork or air filters to
this unit heater. Maintain a minimum of 6” clearance to
inlet openings.
3. When mounting the unit to the joists, do not compress
the vibration isolators by over tightening the lag bolt
screws into the joist. Doing so will greatly reduce the
ability of the isolator to dampen vibration.
4. No water-flow can cause a freeze condition resulting in
damage to the coil.
5. Never leave the unit filled with water in a building
without heat unless antifreeze has been added.
6. To check most of the Possible Remedies in the
troubleshooting guide listed in Table 7.1, refer to the
applicable sections of the manual.
