Section 1 – INTRODUCTION
The Model 6020 DryIR® Infrared line heater is designed for drying applications that
requires a clean, responsive, non-contact heat source.
Typical applications for the Model 6020 include:
Water-based drying
Solvent-based drying
Adhesive curing
The Model 6020 includes the following major components:
Heater Module – The heater consists of a polished aluminum reflector that directs the
infrared energy generated by two 1000-watt medium-wave quartz halogen lamps, that are
included with the heater. Heated widths of one-half, one, and two inches (13, 25, and 54
mm) are offered for the Model 6020, with a heated length of 10 inches. Additional lamps

Section 4 – SAFETY
GENERAL: The Model 6020 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.
106920-001 Rev. 1 4-1
Page 11
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.
106920-001 Rev. 1 4-2

Section 5 – INSTALLATION
5.1 UNPACK AND CHECK FOR DAMAGE: Remove the Model 6020 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 6020 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. If a transport is being used in the application, the heater module
should be mounted so it is level with the transport and should be spaced from one inch
(25.4 mm) above the transport surface.
Figure 5-1. Model 6020 Pictured with Optional Mounting Kit
5.3 ELECTRICAL CONNECTIONS: The lamps of the Model 6020 are electrically
wired to an intermediate terminal block within the heater. An electrical schematic can be
found in the Appendix.
Each heater is supplied with an 8-foot (2.4 m) electrical cable. If ordered with the PC
option, this cable is directly hard wired into the Model 5620 power controller.

Section 6 – MAINTENANCE
The repair and maintenance of the Model 6020 includes replacement of the lamps and
cleaning of the reflector.
6.1 LAMP REMOVAL/REPLACEMENT/INSTALLATION: The lamps are
included with the Model 6020 heater, but are shipped separately to avoid breakage. The
following procedure details the process to install or replace the lamps in the Model 6020
(reference Figure 6-1):
Note:
• Remove all power from the heater BEFORE attempting to install/replace the
lamps.
• 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.
Figure 6-1. Model 6020 Spring Clip and Wire Nut Locations
1. Remove end-cover screws.
2. Remove end covers on both ends of the heater.
3. Pull the lead wires out of the wire nuts. (see Figure 6-1).
106920-001 Rev. 1 6-1
Page 14
4. Gently pull the lamp out of the lamp clips, and set aside for disposal.
5. While holding the replacement lamp by the 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.
6. Insert the bare wire of each insulated lamp lead into the wire nut that previously
held the old lamp.
7. Form a loop within each lead along its length. This loop will act as a strain relief
within the lead during normal operation of the heater.
8. Reinstall both end covers and secure each to the heater with the end cover screws.
6.2 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. This energy
is lost energy.
The following procedure should be used to clean the Model 6020 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 and the heater end covers as outlined in Section 6.1 – Lamp
Removal/Replacement/Installation.
