 3. Drain Connection

Connect the clear Drain/Overflow hose to the connection D at the rear of the softener using the 
herbie clip provided to secure it.

Run the drain hose to either an upstand or an outside drain. A minimum 20mm air gap should 
exist at the and of the drain line to prevent the risk of back siphonage.

If necessary it is possible to extend the drain hose by connecting to a 15mm copper tube. 
The maximum run for this is 4 meters with a minimum daytime pressure of 40psi (2.8 Bar). 
If a run of over 4 meters is required then 22mm pipe should be used.

Ensure the drain hose is adequately fixed to the copper pipe.

The drain hose must not be kinked or be likely to kink over time as this will cause overflow from 
the machine.

If necessary the

 waste pipe only and not the overflow can rise by up to 1 meter if the daytime 

pressure exceeds 2.8 Bar.

The waste from a water softener is suitable for treatment via a septic tank where necessary.

Under no circumstances should the softener waste and overflow share the same pipe.

4. Overflow Connection – Important

The hose for the overflow should be cut from the clear braided hose supplied.
The overflow connection is the ½” spigot at the rear of the cabinet (C in Fig 2) no fixing clip is 
required however the hose should be pushed securely on to the spigot.
The overflow must be run downhill and terminate immediately through an outside wall without 
kinks or restriction.

5. Flush pipework and Test for Leaks

With the water softener inlet and outlet valves in the closed position and the by-pass valve open 
slowly open the mains stop valve to flush the pipework. Check For leaks. 

6. Electrical connection

With the power off, connect the transformer to a suitable 13amp power supply. 
IMPORTANT: make sure the power supply is continuously live.
Connect the fly lead to the plug at the rear of the water softener.

7. Check Your Water Hardness

Using the test kit supplied 
Run the hard water for one minute.
Take a 10ml sample.
Add drops of the green solution to the sample. This will turn red.
Count the drops while gently mixing the drops with the sample.
The sample will turn from red to green.
The 

number of drops required to change the sample green is the water hardness setting you 

will need for setting the controller.
