4.5 How to Obtain Service

If the 2105 is in a humid location or submerged, a hydrophobic
filter prevents water from entering the desiccant cartridge. Any
amount of water will plug the filter and it must be rinsed with
clean water and allowed to dry, or replaced to prevent internal
damage to the module.
Remove the hydrophobic filter with a
screw in the replacement filter (Isco part #209-0093-93).
If the hydrophobic filter frequently requires replacement, con-
sider relocating the modules so that they are better protected.
The communication connectors on the 2105 contain O-rings that
need periodic treatment with silicone lubricant and replacement.
Whenever you replace the O-rings, or have removed them from
the connectors for some reason, you should lubricate the O-rings
by applying lubricant around the circumference of the ring.
Note
Do not use petroleum-based lubricants. Petroleum-based
lubricants will cause the O-ring to swell and eventually deterio-
rate. Aerosol silicone lubricant sprays often use petroleum
based propellants. If you are using an aerosol spray, allow a
few minutes for the propellant to evaporate before proceeding.
The internal components of the 2105 are not user-serviceable.
The 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 Isco's Technical
Service Department.
Corresponding with a Teledyne Isco Technical Service Represen-
tative can often resolve the problem without the need to return
the item. If the difficulty cannot be resolved you will be issued a
Return Authorization Number (RAN) and information on
returning it to the factory.
