Why can’t the the vacuum pump reach full vacuum?

Read intallation guide above before use the gauge kit. 90% cases are leaks or closed valves. Re-tighten all connections, fully open blue & red valves, and ensure yellow hose goes to pump. Spray soap water to find bubbles-–that’s the leak.

Vacuum pump turns off and does not work.

Please check the pump with 2 steps:1. Open the capacitor box to check the capacitor cable. If it is off, connect it and try to work. 2. If there is no problem with the capacitor box, disassemble the fan hood and turn the fan to see if it is stuck.

I only received the vacuum pump, missing all gauges and adapters. What happened and what should I do?

This set was packaged in a large carton, there are two inner boxes, includes pump and hvac gauge. The outer package is labeled "This is a set, Do not separate". If you received incomplete package, please tell us, we will send you missed part.

My pump appears to be leaking oil. What should I do?

First, check if the oil drain/fill screw is tight. If so, stains might be condensed oil mist from long-term use, not a leak.
