The kit contains:
• four recharge cartridges with pre-mounted membrane and electrolyte. The type of membrane
mounted in the cartridge will be specific to the kit ordered
• anode cleaning tools
• a set of replacement O-rings
• a set of replacement Dacron
The black anode cleaning tool is used to clean the anode of any deposits or residue that may have
formed. It is doubled-ended so it can be used for two membrane replacement processes, each end
being used once.

The Dacron
mesh patches provide protection to the membrane.
