Reference
• The "O" mark for corrosion and scale means that there is possi-
bility of occurrence.
• When the water temperature is 40°C or above or when un-
coated iron is exposed to the water, it can result in corrosion.
Therefore adding anti-corrosion agent or removing the air can be
very effective.
• In case of using the closed type cooling tower, the cooling water
and supplementing water must satisfy the water quality criteria
of closed type system in the table.
• Supplementing water and supplied water must be supplied with
tap water, industrial water and underground water excluding fil-
tered water, neutral water, soft water etc.
• 15 items in the table are general causes of corrosion and scale.
LIFTING METHOD
- When carrying the unit suspended, pass the ropes under the unit and
use the two suspension points each at the front and rear.
- Always lift the unit with ropes attached at fours points so that impact
is not applied to the unit.
- Attach the ropes to the unit at an angle of 40° or less

INSTALLATION
Foundation for Installation
• Fix the unit tightly with bolts as shown below so that unit will not fall
down due to earthquake or gust.
• Use the H-beam support as a base support
• Noise and vibration may occur from the floor or wall since vibration is
transferred through the installation part depending on installation sta-
tus. Thus, use anti-vibration materials (cushion pad) fully (The base
pad shall be more than 200mm).
At least
200mm
