Replace The Water Filter - Labcyte Echo 520 User Manual

6.2.5 Replace the water filter

During plate survey and fluid transfer, the coupler 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 as
the coupling fluid returns to the chiller.
To ensure that the coupler fluid is filtered effectively, Labcyte will replace
the water filter every six months. If the water filter appears discolored or
cracked before the six month maintenance is due, replace it immediately.
