WARNING
Fiberglass Wool!
Exposure to glass wool fibers without all necessary
PPE equipment could result in cancer, respiratory,
skin or eye irritation, which could result in death or
serious injury. Disturbing the insulation in this
product during installation, maintenance or repair will
expose you to airborne particles of glass wool fibers
and ceramic fibers known to the state of California to
cause cancer through inhalation.
You MUST wear all necessary Personal Protective
Equipment (PPE) including gloves, eye protection, a
NIOSH approved dust/mist respirator, long sleeves
and pants when working with products containing
fiberglass wool.
Precautionary Measures:
•
Avoid breathing fiberglass dust.
•
Use a NIOSH approved dust/mist respirator.
•
Avoid contact with the skin or eyes. Wear long-
sleeved, loose-fitting clothing, gloves, and eye
protection.
•
Wash clothes separately from other clothing;
rinse washer thoroughly.
•
Operations such as sawing, blowing, tear-out,
and spraying may generate fiber concentrations
requiring additional respiratory protection. Use
the appropriate NIOSH approved respirator.
First Aid Measures:
•
Eye Contact - Flush eyes with water to remove
dust. If symptoms persist, seek medical
attention.
•
Skin Contact - Wash affected areas gently with
soap and warm water after handling.

Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
1. Remove power to the unit and gain access to the
electric heat elements by removing the horizontal
supply cover.
2. Visually inspect the heater elements for the following:
a. Elements that are no longer secured to the white
ceramic insulator.
b. Elements touching each other or touching metal.
c. Severely kinked, drooping, or broken elements.
3. If an element has detached from its ceramic insulator,
carefully put it back into place.
4. Replace the heater elements if they present symptoms
noted in the above Step 2.a and 2.c.
