5-4. Use of the cooling system
Fig. 1
Fig. 2
Open the water inlet of the cooling system of the
equipment. Put cooling water in the cooling sys-
tem (take care not to allow water to overflow).
5-4-1. Using the cooling system
1) Check to make sure that the drain pipe and water supplying pipe are securely connected to the
equipment.
2) At least 2.5-L water should be put in the cooling system. If the water in the cooling system runs
short, an alarm will sound from the cooling system. (Be sure to use pure water or distilled water.
Avoid the use of tap water or mineral water.)
3) After starting the cooling system for the first time after the purchase, immediately check the tubes
for leakage of water.
4) Plug in the power cord and turn ON the power switch. (Starting the cooling system without supplying
water is strictly prohibited.)
5-4-2. How to feed water to the cooling system, and water changing cycle
1) How to feed water : See Fig. 1. Be sure to wait until the water temperature becomes equal to the
room temperature before putting it in the cooling system.
2) Water changing cycle : It is recommended to change the water once every three months. When you
want to change the water in the cooling system, turn the power OFF, turn the
drain outlet (Fig. 2) to open it to allow the water to be discharged from inside
of the system for cleaning. Then, tighten the drain output and put new water
according to the instructions.
