SERIES FH ELECTRIC INFRARED HEATERS
GENERAL INSTRUCTIONS AND WARNINGS
General
The inherent nature of electric heating products
presents safety hazards such as FIRE or
E ECTRICA SHOCK, that can result in personal
injury, property, or heater damage if used improperly.
The purchaser is responsible for proper installation,
use, and suitability of the heaters to their application
in accordance with NEC, NFPA, OSHA, and any other
state or local standards which may apply.
It is strongly recommended that anyone working with or
around this equipment should read and understand all
product literature and instructions and become familiar
with the heater operation and safety concerns prior to
use.
Users should install high temperature control protection
in systems where an over-temperature fault condition
could present a fire hazard or other hazard. Failure to
install temperature control protection where a potential
hazard exists could result in damage to equipment and
property, and injury to personnel.
Shipping & Handling
If heaters are to be re-shipped, they should be re-
packaged and shipped as received from the factory.
Heaters should always be shipped facing up with at
least 3” of protection on all sides, and securely
packaged or crated. We take a great deal of care in
packaging to assure safe delivery. Upon arrival,
please inspect and immediately report any damage to
the carrier. The customer will be responsible for any
damage or defect occurring after the contents have
been removed, reshipped, repackaged, or replaced.
Installation
ong heater life and high heating efficiency will result
when heaters are properly installed with the following
guidelines.
• Series FH heaters should only be installed by
qualified personnel.
• Series FH heaters can be mounted vertically,
horizontally, or any position.
• The end of the heater with the electrical connection
must be mounted at the lowest or coolest position.
• The supplied mounting brackets allow for heater
expansion. The brackets must be positioned from
the ends as specified below. The other brackets
must be evenly spaced between. The nameplate
end bracket must be rigidly fastened and the other
brackets must be loosely fastened to allow the
heater to expand or grow.

• Recommended distance of at least 2” between the
heater and the product.
• Heaters mounted face to face and closer than 6
inches are not recommended without having a
constant full target, or being controlled by an
automatic temperature controller.
DANGER HAZARD OF FIRE. Heaters are capable of
developing high temperatures; extreme care should be
taken to:
1. Do not mount heaters in an atmosphere
containing combustible gasses and vapors.
2. Keep combustible materials far enough away
to be free from the effects of high
temperatures.
3. Guard against contact between heaters and
combustible materials.
Wiring
CAUTION HAZARD OF ELECTRIC SHOCK. Turn
off and lock out all power to heaters before servicing.
To avoid electric shock and damage to property and
equipment, electrical sensors, or peripheral devices,
heaters must be installed by a qualified electrician in
accordance with National Electric Code and any other
national or local codes required. Failure to do so could
result in injury or death.
Properly rated hook-up wire must be used to connect
electrical power to the heater. The physical and
environmental conditions are determining factors for
the correct wire size, material, and insulation type to be
used. High temperature wire such as MG (mica/glass)
or TG(Teflon/glass) with nickel clad copper conductors
may be required.

Use the ground lead wire to make a good electrical
ground. Do not depend on the aluminum case to serve
as a ground path.
Warranty
The heaters are warranted to be free from defects of
workmanship and materials for 1 year or 4,000 hours,
whichever is first, from date received by customer.
Evidence of misuse, field modification or repair voids
warranty. iability is limited to repair, replacement or
refund of faulty material or workmanship.
Operation
CAUTION HAZARD OF ELECTRIC SHOCK. Internal
elements and hardware are live electrical conductors.
Do not operate without protective screen. Electrocution
and permanent heater damage may result.
ong heater life and high heating efficiency will result
when heaters are properly operated with the following
guidelines.
• Operate heaters at the rated voltage only.
• It is recommended to control the heater output with
SCR or SSR controllers. Controlling heater
temperature at below 100% output will
proportionally increase heater life.
• Do not operate heaters in chamber temperatures
exceeding 400 degrees F. Aluminum cases can
soften and distort.
• Product should not come into contact with or rest
on any part of the heater or it’s face.
• Do not operate heaters at high outputs for
extended periods of time without product present
to absorb the energy.
• Do not leave operating heaters unattended.
• Heaters should not be operated in environments
with factors that can oxidize or destroy the
elements or insulation inside the heater. Water or
water vapor, grease, oils or oil vapors, corrosive
liquids and vapors, noxious or reactive gases, and
contaminants can create leakage (shock) hazards,
permanent heater damage, or cause heater failure.
Maintenance
The heater must be allowed to cool completely, and all
power must be turned off and locked out prior to any
maintenance.
When replacing a heater, only install a heater of the
same style and voltage, and the same or less wattage.
Replacement glass and elements are available for field
repair. Call the manufacturer for details.
To clean a heater, ese only a dry cloth or only damp
with water or mild cleaner to wipe all external surfaces.
Never wash down with any sprayed liquid or solvent.
