WARNING
FOLLOW THE INSTALLATION STEPS IN SEQUENCE TO ELIMINATE ANY
POSSIBLE DAMAGE TO THE SYSTEM.
Equipment Needed:
•Adjustable Wrench or 9/16 Socket Wrench
•2.5 Liters of DistilledWater
1. Laser System Unpacking:
1.1. Using the wrench, remove the front of the crate. Keep the front nearby to use
as a ramp to roll the laser system from the crate.
1.2. Remove the accessories located on each side of the laser system from the
crate.
1.3. Place one end of the front of the crate on the floor. Butt the other end against
the floor of the crate. Grasp each handle and gently roll the laser out of the
crate.
WARNING:Rear wheels must be
locked when removing laser from
crate. Failure to have rear wheels
locked could result in the laser
coming off the ramp.
1.4 Move the laser to the room that has been prepared for its use. Make sure the
required space and electrical requirements are met. To prevent the laser
system from moving inadvertently, lock each front wheel.

2. Coolant system filling:
2.1.Remove the black cap on the reservoir, located on the rear of the laser.
2.2.Add distilled water up to within½ to 1 inch of top of reservoir.
NOTE: Always use distilled water when filling the reservoir. Using water that is
not distilled will result in poor flash lampperformance, and may result in
permanent flash lampdamage.
2.3.Replace the black cap on the reservoir.
2.4.Plug the male end of the power cord into the approved outlet.
2.5.The fluid lines within the laser must now be filled with water. To do this, turn the
system on for 2 minutes then shut it off. Then repeat steps 2.1-2.5until the water
level inside the reservoir remains at within ½ to 1 inch of top of reservoir.
3. Initial Cryogen Canister Installation:
3.1.Remove the DCD cryogen canister from the packaging box. Be sure to read all
labels on the canister before installing into the system.
3.2.Insert canister threaded side down into the opening on the top left side of the
laser system. Turn canister clockwise until hand tight. A small amount of
cryogen might vent out. The sound of the escaping gas may be quite loud. Only
after the canister is fully seated will the gas stop venting out.
3.3.Place the cylindrical canister cap over the cryogen canister.

4. Delivery System Installation:
4.1. Remove theDelivery System from its box.
4.2.With the system turned off, place the distal end of the handpiece assembly into
the calport.
4.3.Connect the handpiece control (round, electrical plug) connector to the
handpiece valve control receptacle on the front of the laser system.
4.4.Connect the cryogen output connector to the cryogen line receptacle on the front
of the laser system: Using both hands, push the knurled connector on the front
of the laser system away from you while gently pushing the mating connector
into the knurled connector until it stops. Release the knurled connector.
4.5.Remove the protective cap on the fiber receptacle located on the front of the
system.
4.6.Remove the cap from the distal end of the fiber. Slide the distal end of the fiber
into the HP Slider until it clicks firmly into place.
4.7.Insert the proximal fiber connector into the proximal fiber receptacle, located on
the front of the system, until it clicks into place and stops.

5. Distance Gauge Installation:
5.1. Refer to figure 1above for distance gauge location.
Note: The distance gauge must be removed before performing the calibration
procedure.
5.2. Insert the distance gauge into the distal end of the handpiece delivery
system.
6. Footswitch Installation:
6.1. Remove the footswitch from its package.
6.2. Attach the tubing end to the bulkhead connector on the rear panel of the

8. Relocation:
8.1. Care should always be taken when moving the GentleYAG.The system was
designed to be moved, but special care should be taken when thresholds,
elevator doors, ramps, and other uneven or sloping floor surfaces are
encountered. A severe physical shock could cause the alignment of the
laser head or the optical fiber to be disturbed. Furthermore, if the system is
allowed to get out of control when being moved, personal injury or physical
damage could result.
8.2. If it becomes necessary to relocate the GentleYAG, call Candela or the
distributor for details. Failure to do so may result in damage to the system,
and may void any warranty.
