NEVER use flammable or corrosive fluids with this chiller. Do not
use automotive antifreeze. Commercial antifreeze contains silicates
that can damage the pump seals. Use of any fluid not listed below
will void the manufacturer's warranty.
Approved fluids are:
Filtered/single Distilled water

0 - 75% Laboratory Grade Ethylene Glycol/Water

0 - 75% Laboratory Grade Propylene Glycol/Water

Deionized water (1 - 3 MΩ-cm, compensated)

Laboratory Grade Ethylene glycol (EG) is poisonous and
flammable. Before using EG or performing maintenance where
contact with the fluid is likely refer to the manufacturer's most
current MSDS for handling precautions.
EG is also hygroscopic, it will absorb water from its environment.
This can affect the freezing point and boiling point of the fluid over
time and may result in system failure.
When using a process fluid mixture of ethylene glycol and water or
propylene glycol and water, check the fluid concentration and pH
on a regular basis. Changes in concentration and pH can impact
system performance.
When using EG/water or PG/water, top-off with plain water. After
top-off check the fluid concentration.
Do not use a Deionization (DI) filter cartridge with Inhibited EG
or Inhibited PG. A DI filter will remove inhibitors from the solution
rendering the fluid ineffective against corrosion protection. Also,
inhibitors increase fluid conductivity.
