The filters in the end caps keep small pieces of the desiccant
material from falling out of the cartridge. When the filters
become soiled, clean with dish soap and water, then allow to dry.
4.2 Hydrophobic Filter The hydrophobic filter prevents
water from entering the module.
Any amount of water will plug
the filter. If the filter becomes
plugged replace it.
To remove the filter, turn it coun-
terclockwise while making sure
the black fitting does not rotate.

4.3 Bubble Line
Maintenance
Periodically inspect the bubble line to make sure that it has not
become kinked or damaged in any way. If you find damage to the
bubble line, replace it. A leaking or obstructed line will cause
inaccurate level readings and lower battery life. (The pump must
run more frequently.) If you need to replace the bubble line,
install a new line the same way you installed the original. Gen-
erally, the new line should be the same length as the old.
If you replace the bubble line or if you change the outlet either by
cutting off the tip or by installing a bubble line extension, you
must recalibrate the level.
Inspect the outlet of the bubble line regularly for any signs of
clogging. Sediment or debris from the flow stream and algae can
all clog the line. If the line is blocked, you can either clean it out,
or simply cut off the tip.
If algae growth is a problem, consider using a copper bubble line
extension. The copper salts formed on a copper line will prevent
algae growth.
4.4 Repairing The Module The module has no user-serviceable parts. Its case is completely
sealed to protect the internal components. To repair the unit, the
case must be broken open and replaced. If you think your module
requires repair, contact Teledyne Isco’s Customer Service
Department for information on returning it to the factory.
4.5 Flash Memory and
Software Upgrades
The module has Flash memory to store its software. With Flash
technology, you can upgrade your module’s software without
sending it back to the factory or replacing a chip.
To update the module software, install the module in a 6712
sampler. Then connect the sampler power source and turn the
sampler on. Connect the sampler to a computer and follow the
instructions received with your Flash Update program.
