Cleaning System using: � Chlorine bleach (surface and municipal water) � MAYTAG MC1 Cleaning Solution (ground water) 10.
This procedure is to be conducted after the internal prefilter has been removed from the System. Do not permit the Carbon Prefilter to come into contact with chlorine bleach or any other form of chlorine. During this procedure the water level in the System should be half way up the internal prefilter cavity. If necessary, add water by slightly opening the inlet ball valve while observing the water level. Always wear safety glasses and protective clothing when handling cleaning chemicals. Add 500mL of household chlorine bleach to System (5.25% as Cl2) OR 250 mL of 12% chlorine pool bleach OR add the MAYTAG MC1 Cleaning Solution following instructions in the package. Cleaning Chemical Used Chlorine Bleach (5.25% as Cl2) Chlorine Pool Bleach (12% as Cl2) MAYTAG MC1 Cleaning Solution
Model MWF4100AWS and MWF4300AWS, any nonwell water MWF4200AWS, well water only
Never intentionally or unintentionally mix chlorine bleach and MC-1 cleaner as poisonous and corrosive chlorine gas may be formed.
Chlorine bleach must be less than 3 months old. The active percentage reduces with time. After the System has soaked it must be flushed as the sanitizing solution in the water supply may irritate the skin or cause illness if ingested. Do not use hot water during maintenance of the System. It is possible that if a hot water tap is used, high levels of chlorine or MAYTAG MC1 Cleaning Solution will enter the hot water tank and cause personal injury, illness and/or death.
Soak 60 min. 11. Allow System to soak 60 minutes. Drain System for 5 minutes using the controller as described in step 4. At the end of 5 minutes the System Controller Manual indicator will turn off or the System Controller flashing light will go out. 12. Re-install Stainless Steel Prefilter or install a new Carbon Prefilter and replace System Cap. When installing a new replacement or a clean, used internal prefilter, the spigot end of the prefilter (refer to Photo 3a and 3b on page 15), is carefully fitted into the inlet on the bottom of the prefilter cavity.
Re-install Internal Prefilter.
