2. Introduction
Thank you for choosing one of ILO North America’s innovative and class-leading IR heating products. It
is our intention that you experience many years of satisfaction. This product has been designed and
manufactured to the highest quality standards.
We hope you will be happy with your purchase and we believe it will simultaneously enhance your
living milieu whilst minimizing your energy bills. ILO North America heating products are designed to
provide thermal comfort through the use of ILO’s proprietary Infra-Red emission technology. Heat in
the form of invisible ‘light’ warms the user directly, without first having to warm up the whole volume
of air in the room. This is most efficient when the panels release most of their heat as Infra-Red, and
as little as possible by convection. Consequently, they are best installed on ceilings.
The health benefits of heating with Infra-Red have been scientifically proven. ILO’s products emit IR
in the safe and beneficial Far-IR end of the spectrum – see page 19 for more information. The Far-
IR heat penetrates deep into the skin and aids blood circulation.
Dust agitation and mold/mildew formation in the living space is minimized, whilst the occupant feels

warm in a room with a lower temperature setting (66.5°F or 19.2°C) than with a conventional heating
system. It is this lower temperature setting that is the primary energy saving when using IR heating.
Note – The dimensions and flatness of these heating panels are subject to change when at operating
temperature. It is also possible the panels make faint sounds as they heat or cool. This is normal and
need be no cause for concern.
WARNING – The ILO Heating Panel is not designed for use as a clothes dryer. Do not cover the
heating panel with any clothing, towels (wet or dry), rugs, curtains etc. These flammable items will
impair the correct operation of the heating panel and might lead to overheating of the panel and fire.
See the following section for guidance on the safe use of this heating panel.
The information in the following sections is designed to help you in determining how best to install
and use ILO North America’s products in your home, office, or workspace.

Model - The model number reflects the panels’ nominal sizes in inches. See Dimensions below
for the precise sizes. The panels are available in matte white (e.g., IHP2424W) as standard with
black (e.g., IHP2424B) as an option.

Initial Current - Denotes the maximumcurrentconsumed when first powered up. This start-up current
decreases as the heater warms up. This current will vary slightly depending on the line voltage.
These figures are given to help in choosing circuit breaker sizing.
5Average Current - Denotes the average current consumed when the heater is warm. The duty
cycle of the heaters is 100% - the heater is generating full power whenever it is on. The panel is
designed to self-regulate its surface temperature to ≈200°F or 90°C. This self-regulation is helped
by the natural heat loss (through IR radiation) of the panel surface (high emissivity) and the PTC
effect of the custom heating element. That is, as the temperature of the element increases, then
so does its electrical resistance which consequently limits the temperature increase.

1IP Rating - According to the International Protection Rating system, ILO Heating Panels are
rated at IP30. This means they are mechanically protected against solid objects greater than
2.5mm (0.10”) causing harm to the heater but have no protection against water spray. These
heating panels are designed for indoor use in non-wetted areas.
2
Protection Class - The ILO Heating Panels are rated as a Class I appliance. This means the
aluminum frame is connected to electrical earth (ground). If a live conductor contacts the frame
then current will flow through the earth (ground) conductor and will either trip the circuit breaker
or the RCD (GFCI) if fitted.
3
Infrared Spectrum - The type of IR energy released by the heater panel is classed as being in
the Far Infra-Red, Long wavelength Infra-Red, or IR-C area of the spectrum, according to the
limits defined by the International Commission on Illumination. Referring to Wien’s
Displacement Law, it can be proven that a body with a surface temperature of 90°C (363 K)
emits energy with a wavelength of approximately 8.0 microns. Refer to page 19 for more
information.

5. Operating Voltage
The ILO Heater Panel is designed for use on 120VAC 60Hz and uses a standard Type B (NEMA 5 -
15P) plug for the North American market. See Figure 5a.
It features Line (Hot), Neutral and Earth
(Ground) pins. Outlets must have a proper
ground connection.
The power cord is approximately 6½ feet
(2.0m) long and is made from heat and
abrasion resistant PVC material.
The plug is molded to the cord and is not user
serviceable. If there is any damage or tears in
the cord insulation then it must be replaced by
a licensed electrician or returned to ILO North
America for repair/replacement.
Figure 5a
Type B Plug (NEMA 5 - 15P)
If a legacy 2 pin outlet (NEMA 1-15R) is the
only type of receptacle available, then a
polarized grounding adapter plug must be
used. It is essential that the grounding lug on
this adapter plug is screwed to the grounding
point on the outlet. As this type of adapter plug
is illegal in some jurisdictions (particularly
throughout Canada), a safer and more reliable
alternative identified in the US and Canadian
electrical codes is to replace the outlet with a
Ground Fault Circuit Interrupter (GFCI)
breaker outlet.
Figure 5b – Grounding Adapter Plug
The cord has a plug as shown at (A) in Figure 5b. An adapter as shown at (C) is available for
connecting three-blade grounding-type plugs to two-slot receptacles. The green grounding lug
extending from the adapter must be connected to a permanent ground such as a properly grounded
outlet box. The adapter should not be used if a three-slot grounded receptacle is available.
For enhanced security it is recommended to install an RCD (Residual Current Device) or GFCI
(preferably with a 30mA tripping point) in the electrical circuit. This will protect the user if there is
current leakage to earth.

6. Installing in a Dropped Ceiling
In buildings with a suspended or dropped
ceiling grid, the panels (IHP2424 and
IHP4824) may be placed in the ceiling’s
grid.
They are sized to fit into standard
suspended ceiling apertures. Theseceiling
grids are available in a 24” square format
for small rooms or in 48” x 24” size for
larger spaces.
The IHP2424 panel is exactly 23.75” x
23.75” and will fit into the grid and be
supported by the main runner (T bar) and
cross tee. The IHP4824 panel is exactly
47.75” x 23.75” and will be uniformly
supported by the runner design of a typical
dropped ceiling structure. See Figure 6a.
Mounting the heating panel in a dropped
ceiling is easy as can be seen from Figure
6b on the right.
During operation, it is possible that the
heating panels curve up slightly. To
ensure the most aesthetically pleasing
installation, standard accessory hold-down
clips may be placed in the corners to keep
the panels level when these expand.
Please contact your ILO North America
representative to obtain a set of these
hold-down clips, if required.
To reduce heat losses in installations with
a large open space above the ceiling
panels, fiberglass (or similar non-
conductive) insulation capable of
withstanding temperatures of at least
200°F (or about 90°C) may be used to
cover the back of the unit.

7. Mounting Instructions
Owing to the relatively low operating temperatures, there are no minimum mounting height
requirements. The units may be placed at any practical height and may be mounted horizontally,
vertically or at any desired angle to blend in with the room’s décor. Ceiling mounting is best for
efficiency as there is virtually no convection. Each panel size has a pair of mounting brackets
supplied when purchased. These brackets are not required for suspended ceiling installations – see page
9. When wall mounting it is recommended to use these brackets. Type “A” brackets are for
the
IHP2424 panel, type “B” brackets are for the IHP4824, and type “C” brackets are for the IHP4141
panel.
Mounting Bracket Dimensions “A” IHP2424
♦ The ILO Heating Panel model 2424 is fitted with a safety latch mechanism that replaces the
need to use safety screws or security wire in wall and “on-ceiling” installations. Owing to the
design of the safety latch mechanism, the heaters can be removed from the mounting
brackets without the need of tools.
♦ The brackets may be mounted on the wall or ceiling.
♦ For the IHP2424, the primary fastener (hole) pattern is 13½” x 14” (343mm x 356mm).

8. ILO Heating Panels’ Mounting System
Please review the following procedure to install properly an ILO far infrared heating panel. Be sure
to space the brackets correctly, observing the notes on “critical dimensions” in the “Mounting
Instructions” section of this manual (see pages 10-12).
To install the IHP2424, IHP4824, and IHP4141 models, (mounting sizes A, B, and C), mark the
mounting locations using the dimensional information from the previous section and install the
mounting brackets (be sure the brackets face the same direction). Where possible (in joist ceilings
and/or stud walls)at least one of the brackets’ mounting holes should be over a stud or joist. The other(s)
should be installed using appropriate anchors. These anchors need to be chosen after reviewing the
local mounting requirements. This optional anchor hardware is not included as installations vary by
building and region.
Installation:
1. Locate an area near an active power
outlet, or employ an electrician to
provide a power outlet within 6½ feet
(2.0m) of the heating panel.
2. Install the two mounting brackets.
Wherever possible utilize the holds
which are closest to each end.
3. Using a flat blade screwdriver open
the safety latches. See Figure 8a.
4. Ensure that the intended power outlet
or relevant circuit breaker is switched
off.
5. While a helper holds the panel, route
the power cord to the outlet. Do not
activate the circuit breaker for this
circuit until the installation is
completed.
6. Plug the power plug into the outlet.
7. Place the panel near the mounting brackets and engage the right-hand (straight) hook.
See Figure 8b.
8. Slide the panel onto the bracket by holding it gently against the wall or ceiling to engage
the left-hand hook.
9. If wall mounted, pull the top of the panel away from the wall and engage the safety latches
(use a screwdriver or suitable tool if needed). If ceiling mounted, allow the panel to rest
on the brackets, slide it to the latch side and close the safety latches. See Figure 8c.
10. Plug in the panel or engage the circuit breaker and test the panel operation.

14
ILO North America • 5410 West Roosevelt Road • Unit 205 • 60644 • Chicago • Phone: [phone] • Website: http://www.ilo-international.com/
Note: Single person installation is possible by using temporary “s” hooks (obtained locally) in the
“boxed hook” (left-hand side) of the mounting bracket and the holes in the reinforcement
bars. These hooks replace the helper in step 5 above. These hooks temporarily suspend
one end of the panel while the electrical connections are made. To remove the hooks simply
shake the panel and the hooks will drop out. Then install the panel as outlined above.
The ILO far infrared heating panels may be suspended from joist or rafters by steel cables or chains
in a manner compliant with local building codes. It is not advised to use nylon or polyethylene cord
to suspend the panels as these materials are flammable.
When mounting the panels on conventional ceilings local building codes may require additional steel
cables, or chains to secure the panels to the rafters or joists above. Wires, cables and/or chains may
be secured through the appropriate size holes at the ends of the panel’s mounting brackets.
Please contact your ILO North America representative for further advice on mounting panels,
thermostats and/or control systems.
CAUTION! To minimize the risk of fire and to prevent the undesired loss of performance (caused
by voltage-drop) do not use extension cords to power the heaters.
9. Typical Domestic Installations – Ceiling vs Wall
Infrared Heating System – Ceiling Mounted
Recommended Set-up
Figure 9a Figure 9b
• IR Panels mounted on ceilings for highest efficiency. The ideal panel installation
minimizes convection at the panel, and maximizes Infra-Red emission. Convection
depends on the flow of air close to the panel surface, and so the simplest way to minimize it
is to use the panel itself as a barrier to air movement – see Figure 9b.
• When installed as shown in Figure 9a (Horizontal, at ceiling height), the full benefits of
the ILO heating panels will be obtained. The layer of trapped air stays close to the panel,
and consumes little power.
• Wall mounted panels can lead to greater heat losses to outside walls.
• Independent tests have shown 20% lower heat losses/better efficiency with ceiling
mountings.

• WARNING – Do not cover the heating panels with clothing, towels, rugs, curtains or any such insulating
material. This prevents the heating panel from operating correctly and can lead to failure. Such failure is not
coveredby the limitedwarranty.
• With wall mounted installations convections losses are increased due to air currents formed in the room.
See
Figure 9f for an illustration of convection air currents formed on vertically mounted panels.

10. Correct Placement of the Control Thermostat
The mounting height restriction that is normally included with a standard room thermostat can be
ignored with ILO Heating Panels. In a room that is warmed by ILO’s far infrared heaters, the
thermostat may be located at any level between 1 foot (30cm) above the floor, to 1 foot (30cm) below
the ceiling because the typical floor to ceiling temperature difference is only 3.5 to 5.5°F (2 to 3°C).
Standard room thermostats are designed to measure a representative air temperature, which is
present at an average person’s eye level. The thermostat in a convection system has no idea what
the temperatures are near the floor (these may be much lower), nor does it know the temperatures
near the ceiling (these may be much higher).
ILO North America recommends a purpose
infrared designed thermostat (such as a
black ball or black bulb thermostat) is
installed for optimal control and the highest
efficiency - see Figure 10a. These
thermostats are tuned to sense infrared
radiation in a room and not the air
temperature. A standard thermostat is an
adequate substitute if a black bulb
thermostat is unavailable.
Figure 10a – Black Bulb Thermostat
Independent scientific tests have shown the thermostat can be set approximately 3.5°F (1.8°C)
lower when using an infrared heating system to achieve the same level of perceived heating comfort.
In place of the typical 70°F (21°C) setting, the thermostat can be set to 66.5°F (19.2°C). Itis this
lower temperature setting that is the primary energy saving when using IR heating.
With ILO’s far infrared heaters, the differences between floor and ceiling temperatures are so small
that the thermostat may be used at almost any convenient location. This freedom to choose makes
an ILO system an ideal candidate for using a plug-in utility power thermostat. Wherever the power
outlet is located, the thermostat may be used.
11. Using Your ILO Heating Panel
WARNING – Do not cover the heating panel with any materials such as clothing, rugs, curtains,
towels, etc. These products are flammable and covering the heater prevents it from operating
correctly and safely. Covering the heating panel is a violation of the limited warranty.
1. After the heater is mounted on a wall or ceiling, plug the cord into the outlet.
2. Locate the main switch and switch to the ‘On’ position. There are no visible power lights or
indicators on the heater. It is possible the heating panel will make sounds as it heats up. This
is normal and is no cause for concern. It is due to the expansion of the metal frame.
3. After a short while, the heater surface will rise in temperature and start radiating energy.
4. Eventually it will reach approximately 200°F or 90°C.
5. To switch off the heater it is necessary to move the main switch to the ‘Off’ position.
6. After approximately 30 minutes, the heater will be at ambient temperature.

12. Maintaining Your ILO Heating Panel
The ILO Heating Panels are maintenance free during normal operation. In dusty conditions, it is
possible the heaters will require cleaning. Refer to the cleaning instructions below for the correct
procedure.
12.1 Cleaning Your ILO Heating Panel
1. Switch off, unplug the heater from the outlet, and wait 30 minutes to allow the heater to
cool down to ambient temperature.
2. After ensuring the heater surface is cool, clean the heater surface using a damp cloth. Do
not use any strong detergents when cleaning the heater. Only use a cloth lightly moistened
with clean water.
3. Do not spray the heater with water or allow water to enter the heater. Keep all electrical
connections dry at all times.
4. Allow the heater surface to dry completely before plugging the cord into an outlet.
CAUTION!
RISK OF ELECTRIC SHOCK - DO NOT
OPEN - NO USER SERVICEABLE PARTS
INSIDE
As the ILO Heating Panels are maintenance free it is not required for a user to ever open the heater.
The heating panels are secured by rivets to prevent unauthorized opening. No user serviceable parts are
contained within. In the event of a failure, please return the heater to a service representative. See
the Return Procedure on page 21 for more information.
12.2 Storing Your ILO Heating Panel
In normal operation, the heater can be left permanently mounted ready for immediate use. If the
heater needs to be removed for storage during the summer period then follow the instructions
detailed below.
1. Switch off heater and unplug from outlet. If the heater was in use then wait at least 30
minutes to allow heater to cool. Refer to page 13 for instructions on how to remove the
heater from the mounting brackets.
2. Coil power cord no tighter than a diameter of 1 foot (30cm). Use a removable tie to keep
coil intact during storage. Do not kink or damage cord.
3. Store the heater in a dry, dust free location and protect it from mechanical damage.
4. Cover the heater with protective sheeting if the storage environment is inclement.

5. Before using the heater again, it is necessary to remove the protective covering and the
cord tie.
6. Inspect the heater and its cord for damage from mechanical abrasion or rodent attack.
7. Reinstall the heater on its mounting brackets. Plug in the heater, switch it on, and check it
for normal operation.
13. Troubleshooting Your ILO Heating Panel
If you suspect that your heating panel is defective, before returning it to the ILO North America service
center, read the operating instructions carefully, and then please follow these instructions.
a. Unplug the panel, remove it from the mounting brackets and plug it into a known working
alternative outlet. Plug it in directly, without any auxiliary thermostat or outlet
multipliers/power strips. Ensure the main switch is in the ON position. If the heater panel
becomes warm after a short while, the problem is not with your panel, but with the original
power outlet.
b. If there is a doubt about the correct operation of the outlet this can be tested with a lamp
or other known good operating device. If the outlet is dead and no other devices work,
please check your fuses, or circuit breakers or call an electrician to correct the problem. Circuit
breakers may trip if too many appliances are connected to the same circuit; this is not
considered an ILO product defect.
c. If the outlet is OK and you have used an optional room thermostat, please check the
settings (make sure it is not switched off). If the fault is determined to be with the
thermostat, please contact your thermostat vendor for repair or replacement.
13.1 Free Technical Support
If you experience difficulty during the installation or subsequent use of an ILO North America
product, you may contact ILO North America's Technical Support department by phone during CST
business hours: [phone]. ILO’s website information is available in the page footer.
13.2 Disposal of Unwanted Electrical Goods
Eventually all electrical goods need to be replaced and the unwanted items must be disposed of
responsibly. E-waste must be disposed of in accordance with EPA guidelines for the USA. The
Government of Canada recommends contacting your local municipality for advice on how to
dispose of or to recycle e-waste.
ILO North America supports the initiative to:
• Reduce your generation of e-waste through smart procurement and good maintenance.
• Reuse still functioning electrical equipment by donating or selling it to someone who can
still use it.
• Recycle those products that cannot be repaired. Computer monitors, televisions and other
electronic equipment should NOT be disposed of with regular garbage, as this is illegal in
California, New York, and other states.

14. Saving Energy with ILO’s Far Infrared Technology
The sun, which is the world’s oldest source of infrared heating, emits a wide radiant spectrum. It
ranges from the safe far infrared warmth, to dangerous and damaging ultraviolet wavelengths. The
sun’s rays travel a great distance through space without requiring a medium to transmit its energy.
ILO’s far infrared (FIR) radiant heating technology operates in the healthy and therapeutic “long
wavelength” part of the sun’s emission spectrum (7,000 to 10,000nm, or 7 to10µ).
Far infrared can be found just outside of the visible light spectrum on the RHS of the picture below.
IR is safe non-ionizing radiation. The rays to the LHS of visible light rainbow banding – UV, X rays,
Gamma rays and Cosmic rays are dangerous ionizing radiation.

This far infrared at 7,000 to 10,000nm wavelengths travels mostly around the air molecules in a
room. As with a standard flashlight, the far infrared light simply passes through the air as the gases
have very little mass. Hence, the air is not heated.
When the far infrared light collides with surfaces (including people and objects in the room) a portion of
the invisible light’s energy is absorbed (causing the surface to heat up slowly) and some is reflected.
The reflected light will eventually collide with another surface/object and heat this up as well, until
all of the bouncing heat energy has been absorbed. This process will continue until the thermostat
reaches its pre-programmed setting and switches the heater off.
As with a wall that has been exposed to the sun, the surfaces within the room will start radiating
heat energy. After the sun has set, the wall will still be radiating the energy that was absorbed and
stored. This is a good example of how far infrared works.
As far infrared does not heat the air, there are significant energy savings over traditional heating
systems.
15. The Advantages of Using ILO Heating Panels
• People perceive radiant heating as being more comfortable than convection heating systems.
According to DIN EN ISO 7730, most people (>90%) react more favorably to Far IR heating
than convection heating.
• The panels are moderately priced in comparison to a conventional water-based central
heating system. The classic water-based convection heating system is very expensive to
install due to the plumbing requirements and the boiler cost.
• Radiant heating is healthier than convection heating as there is no unnecessary air
movement. Mold growth is controlled by low humidity levels and high surface temperature as
a result of radiant heating.
• Far infrared heating stimulates the blood flow, which in turns allows the human body to absorb
oxygen. This, in conjunction with minimal hot air movements reduces drowsiness and
improves productivity.
• Room temperature is more stable as a result of the wall & floor surfaces absorbing IR heat.
Consequently, the thermostat can be set at 66.5°F (19.2°C) rather than the usual 70°F (21°C). If
a door is opened momentarily this has minimal effect on the room temperature.
• Up to 50% proven energy savings over convection systems (universities’ studies). These
studies compared electric IR heating systems with heat pumps – both ground source (GSHP)
and air source (ASHP).
• The ideal heating solution for room additions as no air ducting or structural modifications are
required. Installing extra panels can be cost effectively done by a licensed electrician.
