Synchronising valve body and timer head
To insure the proper operation of the control valve, valve body and timer head should be synchronised in the
service position. Proceed as follows:
Step 1: Timer head
1. Make sure that the control valve is in the service mode; if the control valve is in regeneration, press the scroll
button, thus manually advancing it through the regeneration cycles, until the display shows the time of day:
2.
The flat side on the drive shaft should be pointing down (mark on
the drive shaft pointing up (1)); if this is not the case: refer to Parts
Replacement “Drive motor”.
Step 2: Valve body
1.
Remove the drain hose from the drain elbow.
2. Remove the 6 bolts holding the valve body and cover together.
3. Lift the valve cover away from the valve body.
4. Make sure the arrow on the worm gear is pointing directly towards
the second tooth on the worm drive shaft (facing the front of the
control valve) (2); the 2 holes in the rotor assembly should now be
exactly aligned with the corresponding holes in the seal disk.
5. Make sure the valve cover O-ring is clean and securely installed around the raised rib on the valve cover.
6. Lower the valve cover straight down onto the valve body and press it down firmly and evenly to seat the valve
cover.
7. Install the 6 bolts and tighten them in a cross pattern.
8. Install the drain hose to the drain line fitting.
