4.0 Replacing the DI Cartridge
The ICE deionization (DI) cartridge is located on the blue coolant line.
This cartridge should be replaced every six months and each time the
flashlamp is replaced to maintain coolant integrity.
Deionizing the coolant helps maintain low coolant conductivity.
The conductivity of the coolant should be less than 1.0 μS.cm-1 (or
conversely have a resistivity
≥
1.0 M
Ω
.cm). This ensures the electrical
field generated by the trigger transformer ionizes the gas inside the
flashlamp and reliably establishes the simmer current. Coolant that is
not properly deionized may prevent the lamp from simmering and may
overheat and damage the trigger transformer.
CAUTION: Before proceeding, verify that the ICE450 Key
Switch is OFF. Unplug the AC Mains power cord.
1. Disconnect the blue coolant lines from the back of the ICE450
Power Supply and from the Laser Head.
2. Drain the coolant from the blue line into a suitable container.
3. Locate the DI filter cartridge and note the flow arrow direction
before removing.
4. Push the collet in against the face of the cartridge fitting. With the
collet held in this position, remove the tube stem.
CAUTION: Failure to follow this process causes the collet teeth
to damage the surface of the O-ring of the internal coolant line
fitting.
5. With the flow arrow for the new cartridge oriented correctly (away
from the ICE), push the tube stems into the fittings on the new
cartridge until they hit the internal stop.
6. Test the cartridge installation by attempting to pull the coolant
lines out of the cartridge. Ensure that the tube stem is fully
inserted before continuing to the next step.
7. Reconnect the coolant lines to the back of the ICE450 and to the
Laser Head, then refill any lost coolant.
