5. Lifting method

Caution:
Be very careful when carrying the product.
- Do not have only one person to carry product if it is more than 20 kg.
- 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.

6. Installation of unit and service space

6.1. Installation

• Using the anchoring holes shown below, firmly bolt the unit to the base.
[Fig. 6.1.1] (P.2)
A 4-ø14 (Anchoring hole) B (Top view)
Bases
• Be sure to install unit in a place strong enough to withstand its weight. If the base
is unstable, reinforce with a concrete base.
• The unit must be anchored on a level surface. Use a level to check after installa-
tion.
• If the unit is installed near a room where noise is a problem, using an anti-vibration
stand on the base of the unit is recommended.
Warning:
• Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a personal
injury.
• Have installation work in order to protect against earthquake.
Any installation deficiency may cause unit to fall down, resulting in a per-

• Piping for systems using R410A may be different from that for systems using con-
ventional refrigerant because the design pressure in systems using R410A is
higher. Refer to Data Book for more information.
• Some of the tools and equipment used for installation with systems that use other
types of refrigerant cannot be used with the systems using R410A. Refer to Data
Book for more information.
• Do not use the existing piping, as it contains chlorine, which is found in conven-
tional refrigerating machine oil and refrigerant. This chlorine will deteriorate the
refrigerant machine oil in the new equipment. The existing piping must not be
used as the design pressure in systems using R410A is higher than that in the
systems using other types of refrigerant and the existing pipes may burst.
