The receiver collects the liquid droplets and directs them in a continuous stream to the expansion valve. Moisture which has entered the refrigerant circuit during assembly is collected by the dryer bag in the receiver.

t  Do not remove sealing plugs until just before installation.
t  The dryer bag in an unsealed receiver will become saturated with moisture within a short time and is then unusable.
t  When installing, observe arrow indicating direction of flow, if applicable.
