Water Filter Maintenance
During plate survey and fluid transfer, the coupling fluid is exposed to dust and particles from the air or from the bottom of the
source microplates. The inline water filter on the chiller tubing filters out dust and particles before the coupling fluid returns to the
transducer.
To ensure that the coupling fluid is filtered effectively, Labcyte will replace the water filter at the annual Preventative Maintenance.
If the water filter traps excessive material, it may become clogged or shed trapped particles before the annual Preventative
Maintenance is due. In that case, the water filter element should be cleaned immediately.

The water filter disassembled is made up of three parts: clear bowl, black housing, and stainless steel water filter element.

Tools and materials needed:
l Lint-free swab (P/N 001-11152, ITW-Texwipe TX708A or STX708A), if needed.
l Gloves
l Type 1 Ultrapure Water
Follow the steps below to maintain the water filter:
1. Purge the fluidics.
1. Select Reverse for the Coupler Pump Direction from the Diagnostics window.
2. Once there is a steady stream of bubbles from the intake tube inside the coupling fluid bottle, turn the Coupler
Pump to Off from the Diagnostics window.
2. Put the gloves on.
