The Herschel IR Range consists of high-emission ceramic heating elements mounted in a directional heater unit. The heaters are designed to gently warm people indoors using infrared radiated heat. Infrared heat is emitted from the hot surface of the ceramic heaters and warms the body directly without heating the air in between. As soon as the heater is switched on the ceramic elements start to warm up and full operating temperature is achieved in 5 minutes. As the energy produced is all in the low medium to far infrared region (not visible), there is no light emitted from the heater, but elements can produce a very faint orange glow.
The Herschel IR range must be located in a position to allow proper and efficient use but one that ensures hot parts are not touched accidentally. The recommended installation height of the IR Range is 2.3m to 2.5m (90”-98”) and for IRP4 up to 3m (118″) from the floor and under no circumstances are they to be installed at less than 2.3m from the floor. In all cases units should be installed at a height where they cannot be touched in operation. Consideration should be given to any temporary or occasional additions such as stages or platforms, and the height should be adjusted accordingly. The Herschel IR units should be firmly and permanently attached to the ceiling (for IR360, IRP4 and Pulsar) or wall (Advantage IR and Aspect XL), using the brackets supplied, with the heaters angled down at 60 degrees from vertical.
The heating elements reach very high temperatures without visible signs of the unit being on. Because Advantage IR2 & IR3 are not fitted with a protective grill, the heaters are not for domestic or household use. Also, the heaters must not be used or installed in any commercial premises where they can be accidentally touched or where there is a risk of damage to the ceramic elements.
