The Thermal Regulator is nonserviceable; it must be
replaced if it is defective.
To replace the Thermal Regulator:
1. Turn off the filter pump and all electrical power to
the heater.
2. If the heater is below the water level of the pool,
close isolation valves to avoid draining the pool.
3. Open the Drain Cock under the Manifold Adapter
or remove the Drain Plug under the Manifold to
drain the heater.
4. Unscrew the Thermal Regulator Plug.

When installing a new Thermal Regulator,
attach it to the spring with C-clip (supplied) to help
with installation and removal. Make sure that the
Thermal Regulator seats in the Baffle Plate port. If the
port has a flat side, the frame on the Regulator must be
turned to clear the flat (See illustration above).
