Hi Cliff, I'm pleased to assist you. It's not recommended to remove the covers or disconnect the supply lines without first properly evacuating the refrigerant which is harmful to the environment and can also be dangerous to your health. It's important to have the work done by a qualified technician who has the equipment and knowledge to properly evacuate and recharge the system. This will ensure that the A/C system is working properly and will also help to prevent any damage to the environment.

This condenser may come with a thin layer of oil applied to the fins for protection during shipping and storage. This oil is not meant to be used as a lubricant for the A/C system and should be wiped off before installation. if interested in this condenser, click the link below to continue ordering at a discounted offer today, while supplies last.
