On Model 258 how can I connect the interceptor if I'm working with water too?
Why does my unit cycle on/off continually?
It sounds like you could have a problem with the daughterboard in your power unit. If you want to give us a call we could try a few things to help you troubleshoot your problem over the phone. Also I have attached a link to our troubleshooting guide.
Can you connect hoses for great length?
Yes you can connect the hoses to achieve the desired length. But as for a side note the longer the hose the more chance you will have of losing suction. Suction is lost with longer hoses due to the rigged hoses.
If there is low vacuum suction, what should I check first?
The very first thing to check would be the flapper assembly right under the drain. If the flapper gets a buildup it will not seal properly and you will lose suction out the drain. Also make sure the cones up inside the power unit are clean. If it is a 2 motor system make sure both exhaust ports are blowing. You can also undo the piping that goes into the power unit and check the suction at the power unit and if it is normal there then something could be wrong in the pipes or a port is open. Let me know if any of those help.
Why does it take so long for the red lights to indicate that the carpet is clean?
Are you using the cen tec power head? The dirt sensor will read any debris the the vacuum is picking up. As long as the vacuum is picking up debris the light will remain red on the power head. I would check and make sure that the power head is clean and not clogged. Please let us know if you are having any issues. We want our customers to get the best out of their equipment and satisfaction.
