2. After the complete system has been installed, check that the coolant has been pumped through the system
as follows (see NOTE):
NOTE
The system will most likely require more coolant after turning the system ON for the first time.
a. Place the ON/OFF Switch to ON. The power supply will start to circulate coolant throughout the system.
b. After about 4 minutes the system may shut down if the leads are not full of coolant.
c. Place the ON/OFF switch to OFF. Refill Coolant Tank as needed.
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 using the system.
3. Re-fill the reservoir and re-install the filler cap.
NOTE
Circuitry in the power supply will generate a ‘Low coolant’ message if the coolant level is too low.
