SAFETY INFORMATION
READ THIS MANUAL CAREFULLY before
installing or servicing this product. Improper
installation, operation, or maintenance can result
in death, severe injury, or property damage!
NOT FOR INDOOR RESIDENTIAL USE!
FOR INDOOR COMMERCIAL/INDUSTRIAL USE.
FOR PROTECTED AND UNPROTECTED OUTDOOR USE.
NOT FOR USE IN HAZARDOUS OR EXPLOSIVE
ATMOSPHERES!
INSTALLATION AND SERVICE OF THESE
PRODUCTS MUST BE CONDUCTED BY TRAINED
PERSONNEL EXPERIENCED WITH ELECTRICAL
EQUIPMENT.
CLEARANCES TO COMBUSTIBLES A S
DOCUMENTED IN THIS MANUAL AND ON THE
HEATER MUST BE MAINTAINED AT ALL TIMES!
Combustibles: Failure to maintain minimum
clearances to combustible materials can result in
serious re hazard. Locations used for storage of
combustible materials must have signs posted to
specify maximum permissible stacking heights such
that required clearances are maintained. These signs
must be conspicuously located or adjacent to heater
thermostats.
Vehicles: These heaters must be installed such that
the minimum clearances described in this manual are
maintained from vehicles parked below the heater.
Suspension: The use of appropriate mounting
hardware (beam clamps, chains, rods, turnbuckles,
etc.) are a must. The weight of the heater must
be entirely supported from a permanent part
of the building structure having adequate load
characteristics.
Do not attach ductwork to this heater or attempt to
use it as a make-up air heater. Such use voids the
warranty and may create unsafe conditions.
Do not insert ngers or foreign objects into the heater.
Do not block or tamper with the heater while it is in
operation. Do not touch heater while it is in operation
or just after it has been turned off, as some parts may
be hot enough to cause injury.
Make certain that the power source conforms
to the electrical requirements of the heater.
Disconnect power before installing or servicing.
If the power disconnect is out of sight, lock
it in the open position and tag it to prevent
unexpected application of power. Failure to do
so could result in fatal electric shock.
WARNING: DO NOT DEPEND UPON A
THERMOSTAT OR OTHER SWITCH AS THE SOLE
MEANS OF DISCONNECTING POWER WHEN
INSTALLING OR SERVICING THE HEATER. FOR
CE APPLICATIONS AN ALL POLE DISCONNECT
WITH CONTACT SEPARATION OF AT LEAST
3mm MUST BE USED. ALWAYS DISCONNECT
BREAKER AS DESCRIBED ABOVE. FAILURE
TO DO SO COULD RESULT IN FATAL ELECTRIC
SHOCK.
This heater is intended ONLY for permanent
installation in accordance with the National
Electric Code (NEC), all applicable local codes
and ordinances, and all sections of this manual.
Any variance voids the warranty and may create
unsafe conditions.
USE COPPER WIRING ONLY
Special attention must be given to any bonding*
(grounding) information pertaining to this
heater. To prevent the risk of electrocution, the
heater must be securely and adequately bonded.
This should be accomplished by connecting a
conductor between the service panel and the
green grounding screw provided on the heater.
To ensure a proper bond, the bonding means
must be tested by a qualied electrician.
Check branch voltage. Heaters should be
operated at voltages no higher than the heating
elements and the heater are designed for. (Lower
voltages, however, pose no problem other than
a loss of wattage). Heaters are not intended for
process heating applications.
In cases where property damage may result from
malfunction of the heater, a back-up system or a
temperature alarm should be used.
*Bonding is the term that describes the completion of the
electrical circuit back to its source, which allows a breaker or
fuse to clear if a short occurs in the line.
