4.0 Filling the Rack ICE450
CAUTION:
Do not operate the system until it has been filled.
Running the pump without coolant may damage the pump.
Running the pump without the Laser Head connected may result
in pump failure due to overpressure.
Complete all preliminary steps prior to laser operation, including
visual inspection for damage, filling coolant, properly connecting
all cables, and performing all laser safety precautions.
Always drain the system before shipping or storage. See
Draining a Rack ICE450 on page 70
Use only distilled water with 1M

1. Connect the fill/drain tube and vent tube to the fill/drain bottle.
Press firmly until you hear the fitting snap into place.
2. Connect the fill/drain tube to the ICE front panel Fill/Drain
fitting. Connect the vent tube to the ICE Vent fitting.
3. Remove the cap and fill the bottle with the approved coolant.
4. Raise the bottle higher than the ICE reservoir. Keep the fill
bottle cap loose.
5. Allow coolant to flow into the ICE reservoir until it rises into the
vent tube.
6. Turn the Key Switch ON (“I”) to power the system.
The pump turns ON automatically when the system is powered
ON. Coolant from the ICE reservoir flows into the coolant lines.
When the coolant falls below the minimum level, the pump
automatically turns OFF and the reservoir-level window lights
blink.
7. Using the Remote Box System menu, set the pump to Fill
mode. See
8. Refill the bottle. Continue adding coolant until the level is well
above the reservoir-level window minimum line. When the fluid
level is sufficient, the pump automatically turns ON and again
fills the lines with coolant.
Note:
If it takes more than three pump cycles to fill the lines, turn the
power OFF. Wait five seconds, then turn the system ON again.
The reservoir-level lights remain ON whenever the coolant is above
the required minimum.
9. Filling is complete when the coolant level is stable and the pump
remains ON.
10. Replace the fill/drain bottle reservoir cap and disconnect the fill/drain
bottle from the ICE front panel.
11. Purge air bubbles from the Laser Head by tilting it vertically with the
coolant circulating for 10 seconds.
Note:
Any time the Laser Head has been disconnected and reconnected, follow this
procedure to purge all of the air from the Laser Head and coolant lines before
operating the laser.
12. Remove the protective sticker from the Laser Head before operating the
system.
