AIR CONDITIONER EXPANSION VALVE REPLACEMENT - CONTINUED
Tag all lines and wires prior to removal to aid in installation.
Remove nine screws (1) and cover (2).
Use care to prevent refrigerant from touching your skin or eyes. Liquid refrigerant, when exposed to air,
quickly evaporates and will freeze skin or eye tissue. Serious injury or blindness may result if you come in
contact with liquid refrigerant.
Remove insulation tape and strip caulk around expansion valve (3).
Water and dirt can damage refrigerant system. Five minutes of not being capped is the limit for any hose or
component. DO NOT blow shop air through refrigerant hoses. Shop air is wet (humid).
DO NOT disconnect refrigerant fittings using only one wrench. Hold one fitting in place using a wrench and
turn other fitting with a second wrench.
Tag and disconnect refrigerant lines (4) and evaporator coil inlet and outlet lines (5) from expansion valve (3). Install
plugs in refrigerant lines, evaporator coil inlet and outlet lines, and expansion valve. Discard preformed packings.
