It is a start device, but there is nothing soft about it. Because of their simplicity, hard starters work best when all operating conditions are normal. If or when something does go wrong, they can fail AND damage the compressor winding, as well. Like pulling a vacuum with a micron gauge or proper recovery, it was a wink and nod proposition rather than a real practice. Since there is a lot of room for inaccuracy in extreme climates (especially those with high latent loads), many HVAC systems are oversized and underperform. Before starting work, make sure that the component you are working on is completely void of compressed air, and that no adjacent equipment is still charged. VLT soft starters; VLT legacy soft starters ; Follow our global channels Keep me updated.

Their recommendations varied from buying a larger generator to installing a hard start kit but we didn't want to spend big money on a larger generator and the hard start kit would only reduce the starting amps a little so it might not work. Game Changing Soft Starters 1. A soft start valveprevents air cylinders from slamming back to their home position after the main air supply is exhausted from the machine. In one part they say "Reduces inrush start-current by 70%", but in the specs it says "Start current reduction - 60%70% of LRA", then next says "Startup torque reduction - 30-40%". Threshold is the trigger threshold. This start-up power is known as Locked Rotor Amps (LRA): it lasts fractions of a second, drawing enough power to ramp the compressor from idle to full torque before switching to normal operation. Mount the soft starter box inside the air conditioner box with sticky-sided tape or screws. *Prices are pre-tax.
