3.11 Filling Master Power Supply
Coolant
NOTE
Only the Master Power Supply requires coolant.
DO NOT install coolant in the Slave Power Sup-
ply or the second Master Power Supply if used.
The ambient temperature of the environment where the Power
Supply will be located determines the coolant to be used. The
Standard Torch Coolant supplied with the system can be used in
ambient temperatures down to 10° F (-12° C).
Optional Super Torch Coolant should be used in areas where
the ambient temperature drops down to -27° F (-33° C).
CAUTION
Use only Thermal Arc Torch Coolant. Use of any
other coolant can result in torch damage, insuffi-
cient thermal protection, and/or pilot arc interfer-
ence.
1. Locate the coolant deionizer bag and remove from
the plastic shipping bag.
2. Remove the coolant filler cap from the reservoir
at the top rear of the Power Supply.
3. Place the deionizer bag into the basket in the cool-
ant reservoir.
