Hi,

First, here are the directions for vacuuming and recharging the system:

WARNING!
- Always use an Underwriter's Laboratory (UL) approved refrigerant recovery/recycling/recharging unit such as Kent-Moore ACR4, or equivalent when evacuating and recharging an R-134a A/C system.
- Any person who services a motor vehicle air conditioner MUST, by law, be properly trained and certified and use approved refrigerant recycling equipment Technicians must complete an EPA approved recycling course to be certified.
- State and local governments may have additional requirements regarding air conditioning servicing. Always comply with state and local laws.
- Always wear safety goggles when discharging, evacuating and recharging an A/C system.


CAUTION!

I attached a pic below that shows the system.

Here are two links you may find helpful. The first one explains how to install Freon. The second is a more detailed guide for vacuuming and recharging.

By the way, the pressures are somewhat determined by outside temperature. If you let me know the outside temperature when charging it, I can tell you where it should be.

I hope this helps. Let me know if you have other questions.

Take care,

Thanks for the reply. The current temperature in Seattle is 73F, but it will be up to 84F this afternoon when I have the chance to recharge the system.

I will start by filling with refrigerant, since that is the more immediate, easier thing to do. thanks for the links. If there are defective parts which need replacing, then I will look for a qualified service nearby.
