Installation ‐ Refrigerant Filling
24
NOTICE
The chiller will require more coolant than the volumes listed above to fill the chiller internal
plumbing, plasma cutting system internal plumbing, and the connecting hoses.
After the pumps have been started for the first time, additional coolant will likely be required
as the internal system components are filled with coolant.
When the chiller’s controller is powered, the coolant reservoir level can be monitored via the
controller (refer to Section 8.5).
6.10 Refrigerant Filling
If the chiller is installed in a fluorinated gas import restricted country or the European Union, it is subject to the
F ‐ gas regulations. For these applications the DTS chiller part number 802092 is shipped with a nitrogen charge
and has no refrigerant. Prior to startup the chiller is required to be charged with refrigerant. DTS can support
charging the refrigeration through its certified contractor network. For DTS service information refer to Section
12.
