6. Maintenance
6.1. Changing the batteries on the combined meter
When the battery symbol (
) appears, the batteries need replacing. Undo
the 4 screws in the red cover, lift off the cover and replace the three 1.5 V
AAA (LR03) batteries with new ones. Make sure the cover seal is seated
properly. Refit the cover and secure with the screws. Check the device is
working correctly.
For detailed information about the combined meter, see the
PUROTAP® LFM-20 product page on our website.
6.2. Changing the batteries on the fill water quality indicator
The battery life is about 2-3 years. After this period, the batteries have to
be replaced. The battery compartment is located at the side of the indicator
head and can be opened using a coin. Rotate the battery compartment cover
anti-clockwise by about 1/8 of a turn. Then pull out the two button cells
(CR2450) and replace them with new ones. Refit the battery compartment
cover.
• Observe the polarity
• Prior to fitting the battery compartment cover, ensure the
seal is properly seated in the meter.
