How to vaccum and refill airdale crac unit , through indoor or outdoor bcoz solinaid valve and expansion valve or closed when Unit is off

[@rhvac]

Depending on the model, the Airedale Crac units usually have a DX condenser outside where the Compressor is located or some of them have the main components such as compressor, indoor and inside the Crac unit. You can connect the Manifold Gauge to the High and Low Pressure service ports of the compressor and use a Magnet to lift the Liquid Line solenoid valve open and recover the system refrigerant, vacuum , pressure test or charge the system 👍

How do I change the machine password and restore the old password?

[@rhvac]

You will need a high level user access password for that. Download the controller manual and you should be able to do that 👍
