INSTALLATION
Valve configuration inspection
The 630 Eurosit can have one inlet and one outlet plugged.
Inspect the control to determine which inlet and outlet are
plugged. The plugs use o-ring seals and are made of brass.
The replacement control must have the same inlet and outlet
plugged as the original control. Use a 5/16" (8 mm) Allen key
to remove and tigten the plug.
The replacement 630 Eurosit has an On/Off modulating
plug (fig. A) installed. To achieve similar performance as the
original control, remove the plug in the replacement control
using a Flathead Screwdriver and set aside. Remove the Min
Rate Screw (fig. B) from the original control and install it into the replacement control in the same
location.
