Vacuum Shutdown Guide

We wish our valued customers, their families and their wash teams all the best during this challenging time.

How to prepare your Vacutech system for a business shutdown

  • Prior to shutting down your system, clean out your arch arms with the system running.
  • While the system is running, walk along your system to listen for any leaks. Address any leaks as necessary.
  • Next, turn your system off as you normally would.
  • Once unit has come to a complete stop, shut power off from the main circuit breaker.
  • Once vacuum system is turned off, pull and store hoses.
  • Empty filter separator debris bucket by accessing the lower door on the filter separator.
  • Check hoses for wear. If hoses are damaged or worn, check your supply to determine if you have new hoses on hand or will need to order new hoses prior to reopening.
  • Cover exhaust muffler to prevent precipitation or debris from entering the system while shut down. To cover your exhaust, use a waterproof tarp, canvas, plastic or similar material and secure it to prevent flapping in the event of wind.

How to care for your Vacutech system for a business shutdown

  • Turn your system on weekly. Begin by removing the exhaust cover. Next, restore main power source to vacuum system, then power up vacuum system.

  • Allow system to run 15-20 minutes, then shut down again. Hoses do not need to be installed during this time.

Routine Vacutech system maintenance to perform during a business shutdown

  • Clean your VFD if your system has one.
    • Make sure power has been disconnected to the VFD.
    • Once power has been disconnected, use light compressed air to blow out VFD and if applicable any VFD filters.
    • If applicable, replace damaged or dirty filter.
  • Check all electrical connections.
    • Re-tighten any loose connections.
    • Re-tape any damaged insulation.
    • Cut back or replace any corroded wire.
  • Clean or replace filter bags.
  • Assess your stock of filter bags. Order more if you are running low. You should always have at least one complete set of new filter bags on hand in case of damage or need to clean and dry used bags.
  • Replace gaskets on debris separator dump valves and separator doors, as necessary.
  • Replace inlet valves, as necessary.
  • Re-silicone connection points along your vacuum piping system.
  • Clean out main vacuum trunk lines, whether you have underground piping or overhead piping.
  • Descale your overhead vacuum piping.
  • Clean arch arms, using Vacutech Arch Arm Cleaning Kit.
  • Assess vacuum hoses and tools for wear or damage. Replace as needed.
  • Assess your stock of hoses, tools, gaskets and other small replacement parts for your vacuum system. Order more as needed to ensure you have adequate stock of needed items.

  • Re-install hoses, ensuring they are not worn or damaged.
  • Remove filter bags and clean separator out.
  • Clean filter bags or replace with new set.
