3. Preparing the Secondary Cooling Water
CAUTION
Use deionized water or purified water as secondary cooling water. Tap water,
industrial water, ground water, or ultra pure water (16 MΩ•cm minimum resistivity)
may cause corrosion or clogging, resulting in fault of the equipment.
Item required
Secondary cooling water (18 liters) and water feed pump
Operating Procedure
(1) Open the front door and remove the lid of the cooling water tank.
(2) Take out the floating panel in the tank.
⇒
Take care not to attach dirt onto the floating panel.
(3) Feed cooling water up to the line under the water level label "HIGH" by using the
attached water feed pump.
⇒
Use the water feed pump only for secondary cooling water and do not use other
uses including kerosene.
(4) Float the floating panel on the water and install the lid of the cooling water tank
as before.
⇒
The floating panel can be repeatedly used. When it is stained, wash it lightly in
tap water with a soft sponge and lastly rinse it in deionized water or purified water
for use.
⇒ When the cooler is operated for the first time after water feeding, the water level
may a little lower. In this case, replenish cooling water again. Before feeding
cooling water, be sure to take out the floating panel.
