• 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

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.

7. Water pipe installation

• Before a long period of non use, purge the water out of the pipes and thoroughly
let them dry.
• Use a closed water circuit.
• When the unit is in cooling mode, add brine to the circulating water to prevent it
from freezing.
• To use brine in the system, DipSW 1-10 must be set to ON.
• When installed in a low-ambient temperature environment, keep the water circu-
lating at all times. If that is not possible, purge the water out of the pipes com-
pletely or fill the water pipes with brine.
• Do not use the water used for this unit for drinking or food manufacturing.

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.

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-
sonal injury.

6.2. Service space

• Please allow for the following service spaces after installation.
(All servicing can be performed from the front of the unit)
