5.9 (Optional) Antifreezing

Context
If the FusionCol8000-C will be idle for a long time, ensure that the circulation
water inside the system has a temperature no lower than 3°C, or has used
antifreeze liquid, otherwise, the heat exchanging pipes of the smart cooling
product may freeze up and crack. If the water temperature does not meet the
requirement, drain all water out of the FusionCol8000-C.
Procedure
Step 1 Remove the plugs from the drainage needle valve 1 and 2 of the heat exchanger,
to drain water naturally until no water flows out.
