Fitting The Vacuum Gauge
A vacuum gauge measures the pressure inside your chamber. This helps you monitor the vacuum level. Follow these steps:
- Find a suitable spot on the lid for the gauge.
- Drill a hole that fits the gauge snugly.
- Insert the gauge into the hole.
- Seal around the gauge with silicone sealant.
Allow the sealant to dry completely. This ensures no air enters. Your gauge should be easy to read.
Sealing And Testing For Leaks
Testing for leaks is crucial. Air leaks can ruin your vacuum pump. Here’s how to seal and test:
- Check all connections and seals.
- Apply silicone sealant to any gaps.
- Fill the chamber with water.
- Watch for bubbles. Bubbles indicate leaks.
Fix any leaks you find. Wait for the sealant to dry before testing again. Your vacuum pump is now ready to use!
