Connecting to the Chiller
When using the chiller, connect the cooling supply to the DSC 4000 as follows:
An appropriate fluid must be used with the chiller. The fluid should be

effective down to –20 °C. Any lower than that would impair the
conveyance power of the chiller's pump. Distilled water is recommended
for operation at temperatures between 15 °C and 90 °C. For operation at
–20 °C to 100 °C, 50% ethylene glycol in water is recommended.

1. Make sure that the chiller is switched off but that its power cord is plugged into a power
supply.
2. Screw one of the barbed hose couplings shipped with the chiller into the OUTLET
connection on the chiller unit, and tighten with a suitable wrench.
3. Couplings suitable for several different hose sizes are provided with the chiller.
4. Push a hose (compatible with the desired coolant) onto the OUTLET coupling and
secure with a hose clamp.
5. Slide the other end of the hose over the metal tube labeled COOLING LIQUID IN on the
thermal analyzer. Place a hose clamp around the hose and metal tube to secure the
hose in place.
6. Screw a barbed hose coupling into the INLET connection on the chiller unit, and tighten
with a suitable wrench.
7. Push a hose onto the INLET coupling and secure with a hose clamp.
8. Connect the other end of the hose to the COOLING LIQUID OUT connector on the
analyzer. Place a hose clamp around the hose and the metal tube to secure the hose in
place.
Setting Up The Chiller
1. Fill the reservoir with coolant.
Ensure that the cooling coils are completely covered. The maximum coolant level is
25 mm below the top of the reservoir.
