Air Cooling – Clean, dry compressed air cooling must also be supplied to the heater for
proper operation if using a quartz window and at all times with the 5194-02 and 5194-04.
This cooling air removes excess heat from around the lamp end-seals. Flexible tubing and
matching plumbing hardware is included with each heater. Required airflow rates and
pressures are listed in the specifications.
Electrical Cable – The Model 5194 heater is electrically wired from the T3 lamp to
intermediate terminal block within the heater. An 8-foot (2.4 m) electrical cable is
supplied with each heater.
Optional Quartz Window – A quartz window can be ordered along with each size of the
Model 5194. When installed in the heater, the quartz window protects the aluminum
reflector and lamp from contaminants released in the heating process, resulting in
maximum efficiency of the heater.
Optional Ceragold End Reflectors – Ceragold end reflectors are available for
installation on the ends of the heater module. These reflectors prevent infrared energy
from radiating past the ends of the heater.
Optional Power Control System – The Model 5194 can be ordered with the ‘PC’
option. This configuration consists of the heater, the Model 5420 ControlIR® 5420power controller, and eight feet (2.4 m) of electrical cable connecting the heater to the

Section 4 – SAFETY
GENERAL: The Model 5194 heater is designed for safe operation. Nevertheless,
installation, maintenance, and operation of the heater can be dangerous for a careless
operator or maintenance person. For your safety and the safety of others, read the
instructions in this Instruction Manual and follow these safety practices to help prevent
accident or injury.
INFRARED RADIATION - CAUTION! Continuous exposure to high intensity
infrared radiation at close proximity could be harmful to eyes or skin. Although infrared
lamps emit negligible ultra violet electromagnetic radiation, harmful burns can still result
if an operator is in close contact with lamps being operated at high intensity.
Because of the brilliant light emitted by infrared lamps at full intensity, it is
recommended that eyes be shielded from the glare if observing the lamps for an extended
period of time. Use suitable shaded lenses or dark glasses.
HIGH TEMPERATURES: Parts of the heater may exceed 500°F (260°C). Contact
with the lamps, reflector, or metal parts near the lamps may cause severe burns.
WARNING!
NEVER place hands under or in front of the heating elements.
ALWAYS allow heating element to cool at least three minutes before touching the lamps
or adjacent parts.
ELECTRICAL SAFETY: There is danger of electrical shock when servicing the heater.
CAUTION! Observe all applicable local and national electrical codes and ensure that a
safe electrical ground system is installed before attempting to operate the heater. Refer to
the Section 5 for proper installation procedures.
WARNING!
ALWAYS disconnect the external power lines prior to servicing the heater.
ALWAYS disconnect the power lines AND any optional interlock circuits before
installing or changing lamps.
NEVER operate the heater with end covers removed.

FIRE SAFETY:
1. Obey the same fire-safety rules you observe when working with hot plates,
propane or acetylene torches, soldering irons, and other equipment that operates at
extremely high heat.
2. Remove all solids, liquids, and gases that burn easily from the area around the
heater.
3. Know where the nearest fire extinguisher is located and how to use it.
4. Know how to put out fire from all the types of material near the heater.

Section 5 – INSTALLATION
5.1 UNPACK AND CHECK FOR DAMAGE: Remove the Model 5194 heater
from its shipping container and associated packaging. Check the unit for any potential
damage due to shipping. In the unlikely event damage has occurred, keep all shipping
containers and materials in order to file a damage claim with the shipping company
responsible for shipping the unit.
5.2 MOUNTING THE HEATER: The Model 5194 heater should be mounted to a
framework or structure that is designed to support the weight of the heater and provide
stability to the unit. Four #10-32 threaded holes are located on the top surface of the
heater and are designed for mounting the heater (see Figure 3-2).
Note: All Research Inc. lamps associated with the Model 5194 heater are designed for
vertical operation, except for the lamps used in the 5194-02 and 5194-04.
Figure 5-1. Typical Model 5194 Installation.
106687-001 Rev. 2 5-1
Page 14
5.3 HEATER COOLING CONNECTIONS: Each Model 5194 is designed with
three ‘quick-disconnect’ fittings protruding from the top of the heater cover. The two
fittings located at the outer ends of the heater are the inlet/outlet cooling water ports. The
single fitting located at the center of the heater is the cooling air inlet port.
All three fittings accept 1/4-inch outer-diameter flexible nylon tubing. A 30-ft. (9.1 m)
length of tubing and three additional quick-disconnect fittings are shipped with each
Model 5194 heater. The tubing should be cut to specific lengths so that both cooling
water and compressed air can be supplied to the heater. The additional fittings should be
used for connecting the tubing directly to the cooling water and compressed air source.
Once cut to the appropriate lengths, each individual tube length should be inserted into
the appropriate fittings on both the heater and the cooling water and compressed air
sources. Figure 5-2 details a typical installation for the Model 5194 heater.
Proper coolant flow must be maintained during operation of the heater. See Section 3 –
Specifications for required cooling water and compressed air flow for each Model 5194
heater size.
5.4 ELECTRICAL CONNECTIONS: The T3 lamp of the Model 5194 is
electrically wired to an intermediate terminal block within the heater.
Each heater is supplied with an 8-foot (2.4 m) electrical cable. If ordered with the
controller option, this cable is directly hard wired into the Model 5420 power controller.

Section 6 – MAINTENANCE
The repair and maintenance of the Model 5194 includes replacement of the T3-style lamp
and quartz window and cleaning of the reflector.
6.1 LAMP REMOVAL/REPLACEMENT/INSTALLATION: The T3-style lamp
is installed into the Model 5194 heater when shipped from the factory. The following
procedure details the process to replace the lamps in the Model 5194 (reference Figure 61, 6-2, & 6-3):
Note:
• Remove all power from the heater BEFORE attempting to install/replace the
lamp.
• Allow a minimum of ½-inch (12 mm) of slack in the lamp lead so that the lead
is not taut when inserted into the lamp terminal block.
• Always take care to handle all lamps by the ceramic end seals and use clean
cotton or latex gloves to prevent contamination of the quartz lamp envelope.
1. Remove end-cover screws (2 per end cover).
2. Remove end covers on both ends of the heater.
Figure 6-1. Model 5194 End Cover Removal.
106687-001 Rev. 2 6-1
Page 16
3. If installed in the heater, remove the quartz window from the heater by sliding the
window out of the slots machined into the reflector body (see Figure 6-2). Take
this opportunity to clean the window using isopropyl alcohol and a clean, soft
cotton cloth (see Section 6-2).
Quartz Window
Figure 6-2. Model 5194 Quartz Window Removal.
4. Loosen (do not remove) the setscrews in the ceramic terminal block on each end
of the heater (see Figure 6-3).
106687-001 Rev. 2 6-2
Page 17
Figure 6-3. Model 5194 Lamp Removal.
5. While holding the lamp, gently pull the lead wires out of the ceramic terminal
blocks, out of the lamp clips, and set the old lamp aside for disposal. (Models
5194-02 and 5194-04 do not have lamp clips, but a half-circle groove that the
lamp fits in.)
6. While holding the replacement lamp by the ceramic end seals, place the lamp into
the lamp clips located on each end of the heater. Orient the lamp so that the gas
fill tip, formed into the quartz tube of the lamp, points out away from the
reflector.
7. Insert the bare wire of each insulated lamp lead into the ceramic terminal block
position that previously held the old lamp. Push each lead wire into the terminal
block far enough so, that when tightened, the setscrew will hold the lead securely.
8. Tighten the setscrews in each terminal block so the lead wires are held securely.
Note: tighten the terminal block set screws to a torque of 0.6 Ft.-Lbs. [0.82 N-m].
9. Form a loop within each lead along its length from the top of the cooling manifold
and the ceramic terminal block. This loop will act as a strain relief within the lead
during normal operation of the heater.
10. Reinstall the quartz window within the heater by carefully sliding the window into
the grooves machined into the heater reflector.
11. Reinstall both end covers and secure each to the heater with the two screws per
end cover.
Note: tighten the end cover screws to a torque of 1.7 Ft.-Lbs. [2.3 N-m].
106687-001 Rev. 2 6-3
Page 18
6.2Quartz Window Cleaning and Replacement: The optional quartz window can
be replaced or removed from the Model 5194 for periodic cleaning. Use the following
procedure to remove/reinstall/clean the quartz window:
1. Remove the two end-cover screws and the end cover from one end of the heater.
2. Gently slide the quartz window out of the grooves within the heater reflector.
Take care so that the quartz window does not bind and subsequently chip or crack
as it is removed.
3. If cleaning the window, use isopropyl alcohol and a clean, dry, lint-free cloth.
After cleaning, do not touch the inside surface of the window unless wearing
cotton gloves.
4. Reinsert the edges of the window into the grooves machined into both sides of the
reflector body.
5. Gently push the window into the reflector until it is completely seated against the
end cover mounted to the heater.
6. Reinstall the other end cover and secure with the two end cover screws.
6.3 Cleaning the Reflector: A clean reflector provides the greatest radiant efficiency.
If the reflector surface becomes contaminated, it reflects less energy. The energy that is
not reflected is absorbed by the reflector, and removed by the cooling water and air. This
energy is lost energy.
The following procedure should be used to clean the Model 5194 reflector:
1. Remove the lamp as described in Section 6.1 – Lamp
Removal/Replacement/Installation.
2. Clean the reflector with a mixture of warm water and common household
ammonia followed by a thorough wipe-down using a clean, water-dampened
flannel cloth.
3. Depending on the type of contamination present on the reflector, a suitable
solvent may be required to remove the contamination. The solvent must be
selected based on its inability to adversely affect the aluminum reflector.
4. Thoroughly wipe the reflector using the warm water/household ammonia mixture
followed by the dampened flannel cloth.
5. Replace the lamps, quartz window (if so desired), and the heater end covers as
outlined in Section 6.1 – Lamp Removal/Replacement/Installation.
