Most of the BaseVac Systems are 220 volt 1 phase. Most should be wired to an external breaker or fuse panel. Check the breaker or fuse panel to ensure they are active.

Second, check the breaker in the BaseVac control panel and reset it if necessary.

The BaseVac panel has a fuse check and replace with the spare taped inside if necessary

Check to ensure the high-level float switch in the air-water separator is wired correctly to the BaseVac control panel. View the switch and ensure it is free to move up and down.

Check if the remote switch is installed correctly, if not a jumper wire should be installed between terminals 10 and 11 to allow manual start.

The BaseVac System requires between 215V and 240V to run at full speed. Check the incoming voltage on the control panel and add a buck/boost transformer if necessary.

The noise is a low RPM noise normally associated with low-voltage. Check the exhaust air blow-off valve, located at the back of the system at the aluminum fitting. BaseVac systems are shipped with a grey schedule 80 plastic pipe adapter., which must be used. It allows internal space for the blow-off valve to fully open, allowing air to exit the pump. If not operating as it should, the pump will not start due to excessive back pressure.

BaseVac vacuum systems provide industry-leading suction, which can expose mechanical room issues initially. When first installed, the vacuum often has enough power to clean years of debris from the lines. This debris can clog piping bends and amalgam separators. Before anything else, clean and flush the lines completely and restart the system.

Check all fittings and connections for leaks. Stronger suction can open cracks that would otherwise not be a problem.

Check the vacuum regulator valve to make sure it is adjusted properly. For more vacuum, twist the valve clockwise (follow instructions on valve).

This normally is a sign that the exhaust blow-off valve is not functioning properly and not letting the air out of the pump.

Check to make sure the exhaust valve is working properly.

Check to ensure the original BaseVac plastic pipe adaptor was used.

If the BaseVac system is connected with an incoming voltage of less than 215V, the motor will fail eventually. Check the voltage and amperage to determine if the motor is failing.

This normally indicates a piping system blockage, as debris can move around, blocking the flow of air intermittently.

The volatility may also be associated with the draining of the air-water separator. When full, the system powers down for 3½ minutes while the tank drains. Depending on the piping system there may be minimal suction during this time.

Check the Air-Water Separator for clogs around the drain, as well
