What to do if my Mantus Compressor is Having Trouble Starting

If the Mantus Compressor is having trouble starting or running, first check page 19 of the manual here for running requirements.

The most common causes for trouble starting include:

– Low power systems. The smallest electrical systems that can start the compressor are 3000W inverter power or a 2000W, 30amp generator. For these systems, try a lower pressure startup. Close your tank valve to seal it off from the compressor. Drain the pressure in the compressor, so the compressor starts against low pressure and draws less peak surge amps. Then once the compressor motor is already spinning, you should be able to open your tank valve.

– Other electrical system causes include use of 15 amp breakers (as listed, our highest running amps can reach 15 amps) or fast-blow Type B breakers that “notice” the startup surge too much. Type C breakers take longer to blow which accomodates the short startup surge of equipment.

– Low water flow. There is a water flow sensor that will cut off the unit or prevent it starting if water pump flow is determined to be low. Reasons for low flow are most commonly a pinched water line or blocked pump filter. The pump filter is visible through the water tank lid. If you have a low flat filter, we have updated to a high cylinder filter that is harder to block. The water flow sensor components can also get stuck with scale buildup. If you run a half cup of white vinegar for 1-2 hours and squeeze the rubber hoses to “surge” the water, this will almost always knock all the scale off.
