3.09 Filling Power Supply Coolant
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 -34° F
(-36° 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 rear of the Power Supply.
3. Carefully pour enough of the supplied Thermal
Arc Torch Coolant into the reservoir to fill it.
4. Reinstall the reservoir coolant filler cap.
5. After the complete system has been installed do
the following procedure to make sure the coolant
has been pumped through the system (see NOTE):
NOTE
Depending on the length of the torch leads ordered
with the system more coolant may need to be added
after turning ON the system for the first time.
a. Place the ON/OFF Switch to ON.
b. After about 10 seconds the system will shut
down (see NOTE).
NOTE
DO NOT allow the pump to operate for more than
10 seconds the first time the system is turned ON.
c. Place the ON/OFF switch to OFF.
d. After 10 seconds place the ON/OFF switch to
ON again.
e. Repeat steps ‘b’ through ‘d’ until the system
no longer shuts down. Depending on the
length of the torch leads this sequence may
need to be done three to five times.
f. After the system stays operational allow the
pump to operate for ten minutes to properly
purge any air from the coolant lines before us-
ing the system.
6. Remove the filler cap, re-fill the reservoir, place
the deionizer bag into the basket in the coolant res-
ervoir and re-install the filler cap.
