PTC Air heater with fan series product instructions:3. The heater can be used in extremely humid air environment. It doesn't matter if a small amount of water droplets are splashed on the surface of the heater but they can't be immersed inliquid.4. The heater's black bracket insulation is high temperature resistant but the metal part is conductive. Please pay attention to safety when using.5. The heater's fan life span is 3~5 years 20000 ~30000 hours.6. The heater is equipped with a chip of 230. When the fan blows the surface temperature of the heater is about 100.When the fan breaks down and stops rotating please stop using theheater to avoid potential safety hazards.7. When the heater is used for the first time there may be a little smoke or odor which is due to the oil stain and heat conductive adhesive volatilization left by stamping aluminiumcorrugation. It is a normaland will disappear in a short time.8. The power of the product is related to the use mode heat dissipation conditions environmental temperature and other factors. The rated power given by us refers to the power measured atthe ambient temperature of 24. Under these conditions the air temperature at 5cm from the outlet is about 50 Celsius. (when the ambient temperature drops the power of the heater willrise.)9. If used in a small enclosed space after working for a period of time when the ambienttemperature near the heater rises the energy consumption of the heater will gradually decrease which is the energy-saving characteristic of PTC products themselves.10. Safety stability energy saving environmental protection and long service life are the most significant advantages of PTC products. The normal use of 5000 to 10000 hours powerattenuation is about 15%.
