Expansion Valve: Service and Repair



Removing And Installing The Expansion Valve

Removal
1. Remove the cover above the heating/air-conditioning system.
2. Remove the refrigerant by suction using the service unit.
3. Detach the air-conditioning lines at the ex- pansion valve. Immediately close connections and lines with plugs so that they are air-tight.
4. Undo the expansion valve and remove it. Immediately close the lines to the evaporator with plugs so that they are air-tight.







Installation
1. Do not remove plugs until shortly before installation. Replace O-rings and wet the new rings with refrigerant oil.
2. Refrigerant oil removed from a previously run air-conditioning system may no longer be used (special-category waste).
