7. Installation of unit

7.1. Installation

[Fig. 7.1.1] (P.2)

A

M10 anchor bolt procured at the site.

B

Corner is not seated.

Fix unit tightly with bolts so that unit will not fall down due to earthquake or gust
of wind.

Use concrete or angle bracket for foundation of unit.

Vibration may be transmitted to the installation section and noise and vibration
may be generated from the floor and walls, depending on the installation con-
ditions. Therefore, provide ample vibrationproofing (cushion pads, cushion
frame, etc.).

Be sure that the corners are firmly seated. If the corners are not firmly seated,
the installation feet may be bent.

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 a strong wind and earth-
quake.
Any installation deficiency may cause unit to fall down, resulting in a
personal injury.

When building the foundation, give full attention to the floor strength, drain water
disposal <during operation, drain water flows out of the unit>, and piping and wir-
ing routes.

Down piping and down wiring precautions

When down piping and down wiring are performed, be sure that foundation and
base work does not block the base through holes. When down piping is performed,
make the foundation at least 100 mm high so that the piping can pass under the
bottom of the unit.

8. Refrigerant piping installation

City Multi R2 Series is constituted by an end branching system in which the refrig-
erant piping from outdoor unit is branched at BC controller and connected to each
indoor unit.
The connection method adapted is brazing connection for high pressure pipe and
low pressure pipe between outdoor unit and BC controller, and flare connection
between BC controller and indoor unit. Brazing connection is employed for joint
pipe set and branch pipe set.

 Warning:

Always use extreme care to prevent the refrigerant gas from leaking while
using fire or flame. If the refrigerant gas comes into contact with a flame
from any source, such as a gas stove, it breaks down and generates a poi-
sonous gas which can cause gas poisoning. Never weld in an unventilated
room. Always conduct an inspection for gas leakage after installation of the
refrigerant piping has been completed.

8.1. Caution

This unit uses refrigerant R410A. Follow the local regulations on materials and
pipe thickness when selecting pipes.

1

Use the following materials for refrigeration piping.

Material: Use refrigerant piping made of phosphorus deoxidized copper.
In addition, be sure that the inner and outer surfaces of the pipes are clean
and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils,
moisture, or any other contaminant.

2

Commercially available piping often contains dust and other materials.  Always
blow it clean with a dry inert gas.

3

Use care to prevent dust, water or other contaminants from entering the piping
during installation.

4

Reduce the number of bending portions as much as possible, and make bend-
ing radius as big as possible.

5

Always observe the restrictions on the refrigerant piping (such as rated length,
the difference between high/low pressures, and piping diameter).  Failure to do
so can result in equipment failure or a decline in heating/cooling performance.

6

Either a lack or an excess of refrigerant causes the unit to make an emergency
stop. Charge the system with an appropriate amount of refrigerant. At such a
time, always properly charge the unit.  When servicing, always check the notes
concerning pipe length and amount of additional refrigerant at both locations,
the refrigerant volume calculation table on the back of the service panel and
the additional refrigerant section on the labels for the combined number of
indoor units.

7

Use liquid refrigerant to fill the system.

8

Never use refrigerant to perform an air purge.  Always evacuate using a vacuum
pump.

9

Always insulate the piping properly.  Insufficient insulation will result in a de-
cline in heating/cooling performance, water drops from condensation and other
such problems.

0

When connecting the refrigerant piping, make sure the ball valve of the out-
door unit is completely closed (the factory setting) and do not operate it until
the refrigerant piping for the outdoor and indoor units has been connected, a
refrigerant leakage test has been performed and the evacuation process has
been completed.

A

Residues in commercially available antioxidants may have adverse effects on
the equipment. Braze only with non-oxide brazing material. The use of other
brazing material may result in compressor damage.
(Refer to item 9.2. for detailed information on pipe connections and valve op-
erations.)

B

Never perform outdoor unit piping connection work when it is raining.

 Warning

When installing and moving the unit, do not charge it with refrigerant other
than the refrigerant specified on the unit.

- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to mal-

function and result in severe damage.

 Caution:

Use a vacuum pump with a reverse flow check valve.

- If the vacuum pump does not have a reverse flow check valve, the vacuum

pump oil may flow back into the refrigerant cycle and cause deterioration of
the refrigerator oil and other trouble.

Do not use the tools shown below used with conventional refrigerant.
(Gauge manifold, charge hose, gas leak detector, check valve, refrigerant
charge base, vacuum gauge, refrigerant recovery equipment)

- Mixing of conventional refrigerant and refrigerator oil may cause the refrig-

erator oil to deteriorate.

- Mixing of water will cause the refrigerator oil to deteriorate.
- R410A refrigerant does not contain any chlorine. Therefore, gas leak detec-

tors for conventional refrigerants will not react to it.

Manage the tools more carefully than normal.

- If dust, dirt, or water gets in the refrigerant cycle, the refrigerator oil will dete-

riorate.

Never use existing refrigerant piping.

- The large amount of chlorine in conventional refrigerant and refrigerator oil

in the existing piping will cause the new refrigerant to deteriorate.

Store the piping to be used during installation indoors and keep both
ends of the piping sealed until just before brazing.

- If dust, dirt, or water gets into the refrigerant cycle, the oil will deteriorate and

the compressor may fail.

Do not use a charging cylinder.

- Using a charging cylinder may cause the refrigerant to deteriorate.

Do not use special detergents for washing piping.
