We hope you will be happy with your purchase and we believe it will simultaneously enhance your living environment while minimizing your energy bills. Si Series heating products are designed to provide thermal comfort through the use of our manufacturer's proprietary Infra-Red emission technology.
WARNING – The Si Series 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.

21. Single heating panel installations may use a plug-in utility power (120VAC) thermostat, which can be purchased from your local hardware/DIY store, or ILO North America representative. 22. Please consult your electrician or an ILO North America representative if you have any safety concerns or questions.

These heating panels are designed for indoor use in non-wetted areas. Protection Class - The Si Series 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.

Max. Ambient Temperature - This is the safe maximum temperature of the local environment the heating panel is mounted in. Max. Ambient Humidity - This is the maximum relative humidity in the local environment for the heating panel. These panels are not designed for use in wet or damp environments. Their protection class rating is IP30, which means no exposure to water is permitted.
5. Operating Voltage The Si Series Panel is designed for use on 120V and 240V 60Hz and uses a standard Type B (NEMA 5 - 15P) plug (120V) for the North American market. See Figure 5a. It features Line (Hot), Neutral and Earth Figure 5a (Ground) pins.
6. Installing in a Dropped Ceiling Figure 6a – Close-up of T-Bar Support buildings with suspended dropped ceiling grid, panels (Si-2424 and Si-4824) may be placed in the ceiling’s grid. They sized into standard suspended ceiling apertures. These ceiling grids are available in a 24” square format for small rooms or in 48”...
Mounting Bracket Dimensions “A” Si-2424 The Si Series model Si-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.

Mounting Bracket Dimensions “B” Si-2448 The Si Series model 2448 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.

Mounting Bracket Dimensions “C” Si-4141 The Si Series model 4141 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.
8. Si Series Panel Mounting System Please review the following procedure to install properly an Si Series 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).
Then install the panel as outlined above. The Si Series 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.

The mounting height restriction that is normally included with a standard room thermostat can be ignored with Si Series Heating Panels. In a room that is warmed by Si'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...
OPEN - NO USER SERVICEABLE PARTS INSIDE As the Si Series 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.
Reinstall the heater on its mounting brackets. Plug in the heater, switch it on, and check it for normal operation. 13. Troubleshooting Your Si Series Heating Panel If you suspect that your heating panel is defective, before returning it to the Spectrum Infrared service center, read the operating instructions carefully, and then please follow these instructions.
14. Saving Energy with Spectrum Infrared’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.
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.
