3.19 Fill the Cooling System

To avoid freeze damage and coolant leakage during shipment, the Power Supply is
delivered with very little coolant. DO NOT OPERATE the System until it has been
filled with coolant.
Important: Never turn on the System when the coolant reservoir is empty or if
Important: When handling coolant, wear nitrile gloves and safety glasses.
Important: Only use approved coolant. Commercially available antifreeze
Remove primary power to the Power Supply.
Ensure all System components are installed and
that all System hose and cable connections have
been made.
Unscrew the coolant reservoir cap from the
top of the Power Supply.
Pour 4-5 gallons (15-18 liters) of approved
torch coolant through a funnel and into the
coolant reservoir. The full level is the
bottom of the reservoir neck. Wipe up any
spilled coolant.
Replace the reservoir cap.
Ensure the torch and consumables are
properly installed.
Apply primary power to the Power Supply.
Power on the Ethernet router/switch and HMI.
Clear the EStop, if installed.
Press the Coolant On button on the FineLine UI > Status Screen > Diagnostics
Screen. Coolant will begin circulating through the cooling system to fill hoses
and torch leads.
Check for leaks in hoses and fittings on the Power Supply, Torch, and ASC.
Allow the coolant to circulate until the flow value stabilizes between 1.2 and
1.5 GPM as displayed on the FineLine UI > Status Screen. If the System
displays a low coolant error, return to step 1 to add enough coolant so that it
is level with the bottom of the reservoir neck.
Press the Coolant Off button to stop coolant flow (FineLine UI > Status
Screen > Diagnostics).
Remove the reservoir cap. Add coolant until the level is at the bottom of the
reservoir neck. The amount necessary is dependent upon the length of the
coolant hoses and torch leads. Longer runs require more coolant, shorter
runs require less coolant. Wipe up any spilled coolant.
