Cleaning and Disinfection Method Statement

Step 1 - Refer to the Risk Assessment.

• Refer to the Manufacturers instructions and safety advice

• Ensure the area is well ventilated.

• Ensure the system is OFF and isolated from external controls.

Step 2

-

Mix Disinfection Solution

• Mix disinfection solution following the manufacturers instructions. L8 recommends 50ppm Chlorine solution 

used for 1 hour. NB: For larger or particularly unclean systems this process may need to be repeated.

• Calculate the total water volume of the system using wet and dry weight values (refer to dimension tables at 

the end of this manual).

Note:

• Depending of the Risk Assessment, it may be necessary to clean the sump tray prior to disinfection.

• Solution loses strength over time and the process may need to be repeated.

Step 3 - Run the unit

• *Note the various control settings in case it is necessary to override them.

• Switch the panel switch to the drain (lower) position to drain water in sump tray.

• Switch the unit to the on (upper) position and allow the tank to refill.

• Place the unit into a RUN condition (*control settings may need to be overridden, refer to the programming 

section of this manual).

Step 4

-

Add disinfection solution- 

• Add the solution to the water sump tray and allow to mix

• Measure the strength of the disinfection solution and check it is the correct strength in accordance with 

manufacturers guidelines.

• Note the strengths of the disinfection solution at 15 minute intervals and record on a 

Record of Cleaning & 

Disinfection

sheet for further reference.

• Adjust solution strength as required.

Step 5 - Circulate disinfection solution

• Check all surfaces are wetted for a minimum of 1 hour at 50ppm.

Step 6 - Neutralise the disinfection solution. - 

• Mix neutralising agent as manufacturers instructions

• Allow the neutralising agent to disperse over the matrix and circulate in the sump tray.

• Measure the strength until the disinfection solution is weak (less than 5ppm)

Step 7 - Drain the unit into foul drain

• Turn Off any fill cycle.

• Drain unit until empty into appropriate drain (depending on Risk Assessment) and rinse the tank if necessary.

• * Where required, reset to original setting and put unit back into operation. Test for correct operation as per 

commissioning section of the manufacturers manual.

• Check for and complete maintenance requirements as per manufacturers instructions.

• Always leave work area clean, dry and tidy.

Step 8 - Recommission the system
