WARNING
CAUTION
Thermo Scientific
The reservoir has a fluid bag filter designed to prevent the introduction of
particulates into the system.
Note The fluid bag filter can be removed with the chiller operating.
Before using any fluid or performing maintenance where contact
with the fluid is likely refer to the manufacturer's SDS for handling
precautions.

For high-temperature chillers, ensure the fluid is at a safe temperature
(below 40°C) before handling.

Figure 6-1 Fluid Filter Bag
Before replacing the reservoir housing ensure the reservoir sight tube
ball stopper is securely in place, see next page.
On ThermoFlex900-5000s, when you remove the bag you will notice a
wire mesh fluid diffuser inside the reservoir supply line, see Figure 6-2. The
diffuser is used to help streamline the flow into the reservoir. After several
bag replacements turn the chiller off and remove the diffuser to inspect it
for debris/damage.
The fluid velocity into the reservoir will rapidly increase with the
diffuser removed and cause splashing. Turn the chiller off before
removing the diffuser. This is especially critical when using ethylene
or propylene glycol.

Note To prevent particulates from entering the reservoir, ensure the fluid
bag filter is in place before removing the diffuser.
Do not operate the chiller unless the diffuser is installed.

When it is time to replace the bag,
gently pull up on the plastic funnel
housing to remove it and simply
pull the bag out of the chiller.
Replacement bags are available from
Thermo Fisher Scientific.
