Service Replacement Valve Assembly

NOTE: Reversing valve assemblies will come
complete with tubing, so excess heat will not be
applied to the valve body.
Tank
On 7k and 9k heat-pump models, a receiver tank
is included in the sealed system. This tank is
soldered to the outdoor coil return line tube.
Check Valve
This valve allows the flow of refrigerant one way
unimpeded, but in heat pump mode it closes and
forces the refrigerant to go through an additional
length of capillary tube. This helps balance the
refrigerant system.
NOTE: Care must be taken when soldering
in the new check valve. Thermal paste and a
damp rag must be used on the middle portion of
the assembly to prevent thermal damage to the
internal check ball assembly.
Drier
All Zonelines will now have a drier factory
installed. The drier must be replaced anytime
sealed system repairs are performed.
NOTE: Driers are vacuumed packed and should
only be opened when it is being installed. Driers
opened and left to the open air become saturated
and should be discarded if not used within 45
minutes.
Heat pump drier kit shown: Includes the check
valve, drier, capillary jumper and process stub
