2. Fill or top off the reservoir using D.I. water or steam-distilled water.
Use the supplied hand op-erated pump for this purpose. Make sure the
water level is maintained between the Min/Max marks on the water
level indicator. The initial fill will drop as the ion exchange cartridge
and particulate filter are filled with water. It is prudent to fill to the
upper level mark.
3. Top off the reservoir as necessary.
CAUTION: Do not use the supplied hand pump to pump
anything other than deionized water or steam-distilled water.
Using it with other liquids will contaminate it for future use.

Optical Fiber Connection

Connection of the Interlock
Signal Cable. If an interlock signal cable
is used on the focusing head or laser room
door, connect the interlock signal cable to
the LW250 Laser as shown in Figure 5-4.

Before Connecting The Fibers.

Verify that the optical fiber's end surfaces
are perfectly clean. To check for fiber end
surface cleanliness use a fiber end face
checker.
After verification, replace the rubber end
cap on the fiber connector. If surfaces are
dirty, clean with optical quality compressed
air blower, or lens tissue. Refer to Chapter
8 for instructions on cleaning optics.
Connecting Fiber to Input Focusing Unit. To connect the fiber to the input
focusing unit:
1. Remove the safety interlocked top cover from the laser housing.
