The auto refill provides makeup fluid to replace any fluid lost to evaporation,
etc. It requires a pressurized fluid source connection to the ¼" Female Pipe
Thread fitting on the rear of the chiller. (If Teflon
tape does not cover the connection's starting-end thread .)
Note ThermoFlex7500s and 10000s with a P3, P5 or T5 pump have a ¼" Male
brass plug installed in the connection, remove the plug before connecting the
makeup fluid.

The auto refill fluid must also meet water quality standards or the valve may
fail to operate as designed, see Section 3.
The auto refill valve input pressure must be < 80 PSI to ensure the valve
functions properly.
Note Adding fluid that has a temperature differential with the fluid already in
the reservoir will temporarily affect temperature stability performance.
The auto refill operates when all of the following conditions are met:
• Fluid is available
• The chiller is turned on
• The fluid reaches a low level condition.
The auto refill shuts off when:
• The fluid reaches the correct operating level.
• The delay timer exceeds user fill time entered in the Quick Start or
SETTINGS menu.
• The chiller shuts down for any reason.
