SERIES 40 ELECTRIC INFRARED HEATERS
GENERAL INSTRUCTIONS AND WARNINGS
General
The inherent nature of electric heating products
presents safety hazards such as FIRE or
ELECTRICAL 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
The glass/ceramic heater face is fragile and will crack if
subjected to severe shock or vibration. Also internal
elements could move out of position if heater is hit on
the side. To reduce these risks, the heaters must be
adequately packaged and ALWAYS SHIPPED ON
THEIR BACK. If shipped on sides, damage can occur.
Upon receiving, immediately inspect glass/ceramic
face for damage, and verify the internal elements are
centered in the case and parallel with ¼” space
between them. If not, please consult factory
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
Long heater life and high heating efficiency will result
when heaters are properly installed with the following
guidelines.
Series 40 heaters should only be installed by
qualified personnel.
Series 40 heaters can be mounted vertically,
horizontally, or any position.
The end of the heater with the electrical connection
must be mounded 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.
CAUTION: When installing a thermocouple, properly
insert it straight into the ceramic sleeve inside the
heater until it touches the backside of the glass face.
When correctly installed, it should drop in without any
force. If it stops part way in or if there is any
resistance, it is not in the ceramic sleeve and should
be removed and inspected. Incorrect installation will
result in an inaccurate reading and may damage or
short out the heater or any connected devices. Any
damage from an improperly installed thermocouple will
not be covered by the warranty.
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. Liability 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 with a broken or cracked glass face
plate. If any object contacts and breaks the glass,
disconnect and lock out all sources of power before
attempting to remove the items. Electrocution and
permanent heater damage may result.
Long 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, the output may periodically be set to
a high setting for a short time to burn off any build up
on the glass/ceramic face. Use 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. Do not get liquid in glass/ceramic face seams.
