Introduction

The included spacer stack and piston(s) are key components in redirecting water within the valve. Although faults are rare, the following faults are indications that the spacer stack may need replacing:

• Water is continuously leaking from the backwash drain line
• Unfiltered water is coming from the outlet
• Error codes 1002 or 1003
• Not using any salt
• The brine tank is overflowing
• Salt water being delivered during service

Kit Inclusions
Unpack the kit. Ensure all parts are present and have not been damaged in transport. You should have:

• (A) Spacer Stack Assembly

Spacer Stack & Piston

1. Isolate the water supply and release the pressure by opening an outlet after the system.

NOTE: If you have the optional bypass assembly, turn the handles so that they point toward each other.

2. Remove the weather cover.On a cabinet-style system,reach around the back of the unit and pull the 2 sides of the cover away from the pipe connection and lift.

3. For the almond cover, squeeze both sides and lift to release.

4. Remove the display front cover by pulling the tabs located on either side by pulling them away from the valve body.

5. Disconnect the power supply, and the flow meter or DP switch cables if present. The motor connection on the bottom left can remain connected.

6. Remove the Drive bracket by lifting the 2 tabs at the top of the bracket.

7. Remove the drive cap assembly. To remove the drive cap assembly, if you have the Puretec WTV5180 spanner and multi-tool, use the
   tool to turn the slotted drive cap assembly anti-clockwise.

Alternatively, if you don’t have the spanner, use a flat-headed screwdriver by inserting it through the slots around the top of the
drive cap assembly and into the notches moulded into the drive back plate. The notches are visible through the holes. Lever
the screwdriver so the drive cap assembly turns counterclockwise.

8. Remove Piston(s) Once the drive cap is removed, you can see the orange piston. The black brine piston is found on the softeners
   only.
   To remove the black brine piston, slide sideways to unsnap it from its latch taking care that it is pressed in the direction of the latch
   opening.

To remove the main piston(s), turn the white gear anti-clockwise so that the orange piston is fully extended. This will allow the piston
to be removed from the spindle and replaced. Unsnap the main piston from its latch by pressing on the side of the piston with the number.

9. Next, remove the grey spacer stack assembly and replace it. The spacer stack has external and internal O- rings for redirecting the water during regeneration or backwash. The internal O-rings are the most common point of damage. The internal O-rings have a custom profile so are not individually replaceable. To remove the spacer stack, simply pull it out with a thumb and forefinger.
10. To reassemble, insert the new spacer stack. If required, use the supplied silicone grease to lubricate the O- rings and piston.
11. Insert the drive cap and piston(s) into the spacer stack and valve body then tighten, taking care to screw it all the way in without over tightening. If you have a softener, make sure the black brine piston is secure before inserting it into the spacer stack.
12. Insert the drive bracket into the bottom locators, and click back into position. If it doesn’t snap in easily, check that the wiring is out of the way.
13.  Re-attach the cables and front display cover.

Flow Control Servicing

1. Isolate the water supply and release the pressure by opening an outlet after the system. If you have the optional bypass assembly, turn the handles so that they point toward each other.

2. On top of the control valve, remove the red clip closest to the front of the unit and remove the fitting. This is the drain line flow controller. Inspect the rubber ring and ensure it is free of any obstructions.

3. [Softener only] On top of the control valve, remove the red clip closest to the back of the unit and remove the fitting. This is the brine line flow controller. Inspect the rubber ring and ensure it is free of any obstructions.

4. Reassemble ensuring the fitting is fully inserted and locked in with the red clip(s)

Replace the Backup Battery

1. The battery (CR2032 coin) keeps the time in case of a power outage. The battery should be replaced annually or after extended periods without power.
2. Reset the time if needed by following the instructions in the user guide for your model.
3. If your system is backwashing only (no salt), then replace the weather cover to complete the service

Brine System Servicing [Softener Only]

1. Isolate the water supply and release the pressure by opening an outlet after the system.
   Note: If you have the optional bypass assembly, turn the handles so that they point toward each other.

2. Remove the injector cap. To remove the injector cap located on top of the valve, first remove the brine clip and the elbow fitting. Next use the Puretec WTV5180 spanner and multitool to remove the injector cap by turning anti-clockwise. If you don’t have the tool, a large set of multi grips or a strap wrench can be used with care.

3. Flip the cap over and remove the injector screen located in the centre of the cap. Clean the screen and replace it back in the cap.

4. Flush the injector feed port. With the injector cap still off, slowly open the inlet water so water is coming out of the injector feed port
   as shown in the image. After a short flush, close the inlet water.

5. Remove the brine injector (labelled DN). To remove the brine injector, use the injector cap to lever the injector out as shown in the
   image.

6. Check the injector is clean and free of debris and blockages.

7. Re-insert the injector and push firmly to make sure it is all the way in.
