Precautions for using electric roller blinds in winter

The use of electric roller blinds in winter, the following precautions need to pay more attention to ensure its safe and efficient operation and prolong the service life.

• Temperature 

Anti-freezing protection: in extremely cold temperatures, the internal mechanical parts and electronic components of the electric roller shadesr are susceptible to freezing damage. If the roller shades is installed in the outdoor garage without heating facilities, terrace and other places, when the temperature is lower than the product specified low-temperature threshold (usually in -5 ℃ to -10 ℃, the brand varies), you can consider adding auxiliary heating equipment, such as a small heater, pre-heating the installation space, to enhance the temperature around the roller shades, to avoid the lubricant coagulation, the plastic parts become brittle, to protect the smooth operation.

Temperature adaptation time operation: just experienced a significant drop in temperature, do not rush to frequently start the rolling shades. For example, the lowest outdoor temperature in the early morning, the rolling shades material contraction, mechanical bite close, this time forcing high-frequency opening and closing, motor load, chain easy to jam. Should wait for the sun a little warmer, the environment warmed up after the operation, to the rolling shutter ‘warm-up’, reduce the risk of damage caused by the sudden change in temperature components.

• Cleaning and maintenance

Dusting in addition to snow: winter sand, snowfall, rolling shades surface accumulation of dust and snow affects the beauty and aggravate the burden of operation. With a soft brush, duster regularly sweep the surface of the floating dust, in case of heavy snow to clean up the snow in a timely manner, pay attention to do not use sharp tools to scrape the curtain to prevent scratching. Like the northern blizzard, if the curtain half open by the thick snow pressure, clean up from the top of the snow pile gently pushed to slide down, and then completely open shake off the remaining snow.

Track cleaning: electric roller shutter track is easy to accumulate dust, stuck in small ice ballast, hindering the movement of the slider. Use a hoover with a fine mouth suction head to clean the track groove, and then wipe with a dry cloth, if icy, you can apply a small amount of medical alcohol to melt the ice, dehumidification, to ensure that the track is smooth, the motor drives the curtain up and down without obstruction.

• Operation

 Avoid overloading: winter clothing thick, clutter, often people want to conveniently hang under the roller blinds put too many items. But the electric roller shutter has a rated load, overloading will burn the motor, pulling the curtain rope. Clarify the product specification label load capacity (common household models 20 - 50 kg), not overloaded use.

Even speed operation: when operating the remote control or switch, press to smooth, even speed, do not frequently and quickly press the start, stop button, to prevent the motor instantaneous current impact is too large, damage to the internal circuit and gear components, each time the opening and closing as far as possible to complete the action, simulate the effect of manual smooth pushing and pulling. 

• Power supply and battery (if any)

Power supply stability: low temperature makes the circuit resistance increase, battery performance decline. Connected to the utility shutter, check whether the socket is loose, whether the wire is broken aging, to ensure that the power supply is stable; battery-powered, such as wireless remote control shutter, regular charging and discharging, charging at low temperatures in the indoor warm place, to avoid low-temperature precipitation of lithium, the capacity of the battery plummeted to ensure that the power reserve is sufficient to ensure that the key moments of normal operation.

•  Material maintenance

Curtain moisture and mildew: winter indoor and outdoor temperature difference, high humidity, rolling fabric is easy to moisture and mildew. Sunny days to open the curtain ventilation to dry, in order to dilute the water vapour; if found mildew, with a soft cloth dampened with light salt water and wipe, and then dry, can not be exposed to sunlight caused by the material fading and aging, waterproof coating of the curtain, but also need to pay attention to the coating with or without flaking, and timely reapplication of maintenance agents to maintain. waterproofness.

Metal parts rust: roller shades metal rails, brackets and other parts, long-term contact with humid air rust. After wiping clean, apply anti-rust oil, petroleum jelly, focusing on the application of screws, articulation, the formation of a protective film, isolation of water vapour and oxygen, and regular inspection, rust stains in time to sanding, to prevent the spread of rust, solid roller shades structure.
