3. Rub Slayer lubricant on the inside face of the actuator hub, the nylon
ramp inside of the actuator hub, and all corresponding contact points on
the x-frame.

hub. If the hubs do not fit snugly, remove the shoulder bolt and actuator
hub and add more shims.

When the expansion valve seal wears, leaking may occur. This will lead to
temperature loss and premature failure of the water filtration system. To diagnose a
worn expansion valve, look for leaking water in the expansion valve drain tube.
Parts and tools:
•
Replacement expansion valve (part #42000-10020)
•
Replacement copper gasket (part #46000-50150)

2. Use a wrench to remove the expansion valve from the pre-heat tank and
discard.
3. Apply teflon tape to the threads of the new expansion valve and slide a
new copper gasket in place.
4. Install a new expansion valve, tightening with a wrench.
