NOTICE
Observe the cooling water preparation!
The cooling water additive for recirculating chillers (order no. 418-13-410-540) must
be added to the cooling water. This is the only way to effectively avoid damages to the
device due to corrosion or biological contamination.
Warranty claims are excluded if damages to the PlasmaQuant PQ 9000 are due to the
fact that the cooling water additive was not used in accordance with these instructions!
The cooling water must be replaced every year.
