3. Installation and Preparation
This chapter explains where to install the thermo chiller and cooling water.
Installation Place
Follow the attached operation manual for the thermo chiller.
Mounting the DI Filter Replacement Cartridge
Since the DI cartridge deteriorates on contact with the air, it is packed separately.
Mount it before use.
1) Mount the a replacement cartridge with the seal part up. (See figure below.)

2) Mount the lower half of the DI filter with the reverse procedure to removing it.
3) Close the clamp.
4) Mount the drain plug.
5) Close the ventilation plug.
6) Start the thermo chiller with the valve of the DI filter closed.
7) Open the valve on the thermo chiller’s RETURN side only.
8) Open the ventilation plug to remove air, and close it again.
9) Open the valve on the thermo chiller’s OUTLET side.
⇒Check for leaks.
⇒When the cartridge is replaced, the water level of the cooling water tank will
drop. In that case, supply the cooling water.
Cooling Water
Use the cooling water meeting water quality standard established by Japan
Refrigeration and Air Conditioning Industry Association (JRA GL-02-1994 / cooling
water system - cyclic water - makeup water). (Cooling water supplied with the Laser
or distilled water is recommended.)
Tap water, water for industrial use, or ground water may cause corrosion or
clogging, resulting in fault of the equipment.
Connections and Preparations of Each Section
1) Connecting the power supply
When using the attached power cable (PZ1169303), use the terminal suitable for
the terminal block on the customer side.
For wiring, follow the attached operation manual for the thermo chiller.

2) Connecting the tube
Note 1 Tube, TPH0806W-20
Cut the tube into any length in the range of 20 m on each side of IN/OUT.
(Since the required flow can not be secured with a tube over 20 m long, the flow
rate error will occur.)
Install the fiber connector 2.5 m or less from the floor.
Secure the minimum bending radius 100 mm.

When cooling plural optical fibers:
･Up to two optical fibers can be cooled.
･Connect optical fibers in parallel as shown below.
･The maximum length of cooling tube should be 40 m in total. (+++++=
40 m max.)
Note 2 Coupling, SKUSDK8-6
Be sure to insert the insert material (SKITK8 or SKITK6) before connection.
Insert material (SKITK8 or SKITK6)
[Connection method]
a. Without removing the nut, insert the tube into
the coupling and push the end of the tube all
the way in.
b. Tighten the nut with a hand until it stops
moving. Put a mark in this position.
c. Rotate the nut 450 degrees clockwise with a
spanner, keeping the coupling body with
another spanner from moving.

[Reconnection method]
a. Before loosening the nut, check its
position. (This position is used as a
reference in the Step d.)
b. Remove the nut.
Check again that the front ferrule is
mounted at the proper position.
Check that no foreign matter is attached
to the body.
c. Insert the front ferrule until it attaches
firmly to the body and tighten the nut
with a hand.
Take care not to scratch the body with
the end of the tube.
d. Tighten the nut with a spanner until it
goes slightly over the position before
loosened (15 to 30 degrees).
Note 3 Tube, TPS0604W
It is recommended that the length be 100 mm or shorter on each side of IN/OUT.
When the length is longer than 100 mm, the pressure loss becomes greater and
a flow rate error may occur.
Note 4 Fiber connector
･Confirm that the optical unit is connected before fitting pipe.
･Confirm that the Laser is turned off.
･Be careful about IN and OUT.

Wiring
･For the AC power cable connection, follow the attached operation manual for the
thermo chiller.
･Connect the alarm detecting cable (attached AS1172750 (20 m) or optional
AS1172751 (5 m)) to the Laser. Connect the EEXT. I/O (AS1172786)
disconnected from the Laser to the jack side of the alarm detecting cable.

Water Supply
Refer to the operation manual for the thermo chiller.
⇒When the thermo chiller is started for the first time after water supply, the water
level will drop. When it is below the lower level, supply the cooling water again.
CAUTION
Be sure to confirm that the feed-water inlet filter (HRS-PF007) is installed before
supply the water.
Otherwise, the pump may fail due to contamination of foreign substances.
Operation
･For the operation of thermo chiller and flow switch, refer to the attached operation
manual.
･The factory settings are as follows.
Water temperature setting 27°C
Flow switch setting 1.5 liters/min
Electrical resistivity setting 0.2 MΩ･cm
Pressure switch setting 0.1 MPa
When the setting is changed, the thermo chiller may not work properly.
If you need to change the setting, contact us.
Also, the contact input of the thermo chiller has been set before shipment as shown
in the table below. Note that the flow rate cannot be monitored if the setting is
changed.

* The thermo chiller is set to raise alarm with 0.2 MΩ･cm. Do not change the setting. For
details of alarm, refer to the attached operation manual.
Preparing the Cooling Water
CAUTION
Use the cooling water meeting water quality standard established by Japan
Refrigeration and Air Conditioning Industry Association (JRA GL-02-1994 /
cooling water system - cyclic water - makeup water). (Cooling water supplied
with the Laser or distilled water is recommended.)
Tap water, water for industrial use, or ground water may cause corrosion or
clogging, resulting in fault of the equipment.
Draining Water
CAUTION
When draining water for moving the equipment, disconnect tubes to the optical
fiber (both IN and OUT).
Flowing more than 0.1 MPa of air into the optical fiber may break the fiber.

5. Alarm Code
For alarm codes not described below, refer to the operation manual attached to the
thermo chiller.
Alarm code Contents of alarm Measures
AL31
Flowrate trouble:
< 1.5 liters/min (over 30 sec.)
> 2.5 liters/min (over 30 sec.)
･Confirm that the pipe is not broken or
not clogged.
･Confirm that the valve is not closed too
tightly.
AL32 Pressure trouble:
> 0.1 MPa (over 30 sec.)
･Confirm that the pipe is not broken or
not clogged.
･Adjust the valve.
･The union-type small line filter may be
clogged. Clean or replace it.
AL35 Electrical resistivity low:
< 0.2 MΩ･cm
･To keep quality, the DI cartridge is
separately packed at shipment.
Confirm that it is installed.
･Refer to “3. Installation and
Preparation” to check that the DI
cartridge is installed in the right
direction.
･At startup after the equipment has
been stopped for a while, an alarm
may be output until the water in the
pipe is ion-exchanged. Reset the
alarm after a few minutes. Cutting
extra pipe makes the alarm less likely
to be output.
