6
To remove the motor:
1. Refer to Frame 3.8.
2. Remove the condensate trap/siphon. Refer to
Frame 3.17.
3. Disconnect the inline connector block.
4. Place a flat bladed screwdriver in the actuator
slot provided and ease out the actuator.
5. Before replacing the diverter valve actuator
proceed as follows:
a. Re-connect the inline connector
block.
b. Ensure that the switched live to the boiler
is off and that all DHW taps are shut and
that pre-heat is switched off.
c. Hold the mode knob in the reset position
for more than 10 secs.
d. The display will alternate between “d” and
“U” and the actuator will move into the
mid-position.
e. The divertor valve will initially drive all the
way out, this may cause the spindle to
become detached from the body. If this
occurs simply screw back into the body
so the cycle can continue driving fully in
before going to mid-position.
f. Replace the actuator into the boiler.
6. Fit the new motor ensuring the arm is correctly
engaged in the metal fork and re-assemble in
reverse order ensuring the condensate trap/
siphon is refilled with water.
7. Check the operation of the boiler.
Note.
All spares will be delivered in mid-position
therefore ignore point 5 and proceed to point
6 after re-connecting the inline connector.
