5. Install actuator. Using the T30 Torx driver, install the support plate T30 Torx screws (see below) until snug.
Ensure that the support plate bolts are suffi ciently loose to allow for some very slight movement between
the support plate and the actuator. This play will allow the actuator to fi nd the proper position when the
armature clamping nut is tightened down.
6. The actuator armature must be positioned in the un-powered rest position. Make sure "T" marking on
the valve stem is pointing towards mixed outlet. See picture below.
