Reference
• The "O" mark for corrosion and scale means that there is
possibility of occurrence.
• When the water temperature is 40 °C (104 °F) or above or when
uncoated 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
filtered water, neutral water, soft water etc.
• 15 items in the table are general causes of corrosion and scale.

• Install at places where it can endure the weight and vibration/noise
of the outdoor unit .
• The outdoor unit supports at the bottom shall have width of at least

CAUTION
!
Be very careful while carrying the product.
• Do not have only one person carry product if it is more than 20
kg (44 lbs).
• PP bands are used to pack some products. Do not use them as a
mean for transportation because they are dangerous.
• Tear plastic packaging bag and scrap it so that children cannot
play with it. Otherwise plastic packaging bag may suffocate
children to death.
• When carrying in Outdoor Unit, be sure to support it at four
points. Carrying in and lifting with 3-point support may make
Outdoor Unit unstable, resulting in a fall.
• Use 2 belts of at least 8 m (26.2 ft) long.
• Place extra cloth or boards in the locations where the casing
comes in contact with the sling to prevent damage.
• Hoist the unit making sure it is being lifted at its center of gravity.
