 Connect all wiring tightly. Loose wiring may cause over-
heating at connection points and a possible fire hazard.
 To prevent possible hazards from insulation failure, 
the unit must be grounded.
When Transporting
Be careful when picking up and moving the indoor and 
outdoor units. Get a partner to help, and bend your knees 
when lifting to reduce strain on your back. Sharp edges or 
thin aluminum fins on the air conditioner can cut your 
fingers. 
When Installing…
…In a Room
Properly insulate any tubing run inside a room to prevent  Select an installation location which is rigid and strong
enough to support or hold the unit, and select a location
for easy maintenance.
“sweating” that can cause dripping and water damage to 
walls and floors.
Keep the fire alarm and the air outlet at least
5 feet away from the unit.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide 
a solid, level foundation for the outdoor unit. This prevents 
water damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a 
metal frame. Provide a suitable air baffle.
…In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher 
than drifting snow. Provide snow vents.

							Check of Density Limit
The room in which the air conditioner is to be
installed requires a design that in the event of refrig-
erant gas leaking out, its density will not exceed a set
limit.
The refrigerant (R410A), which is used in the air condition-
er, is safe, without the toxicity or combustibility of ammonia,
and is not restricted by laws imposed to protect the ozone
layer. However, since it contains more than air, it poses the
risk of suffocation if its density should rise excessively. Suf-
focation from leakage of refrigerant is almost non-existent.
With the recent increase in the number of high density
buildings, however, the installation of multi air conditioner
systems is on the increase because of the need for effec-
tive use of floor space, individual control, energy conserva-
tion by curtailing heat and carrying power, etc.
Most importantly, the multi air conditioner system is able
to replenish a large amount of refrigerant compared to
conventional individual air conditioners. If a single unit ofthe multi air conditioner system is to be installed in a
small room, select a suitable model and installation pro-
cedure so that if the refrigerant accidentally leaks out, its
density does not reach the limit (and in the event of an
emergency, measures can be made before injury can
occur).
ASHRAE and the International Mechanical Code of the
ICC as well as CSA provide guidance and define safe-
guards related to the use of refrigerants, all of which define
a Refrigerant Concentration Level (RCL) of 25 pounds
per 1,000 cubic feet for R410A refrigerant.
For additional guidance and precautions related to
refrigerant safety, please refer to the following documents:
International Mechanical Code 2009 (IMC-2009)
(or more recently revised)
ASHRAE 15
ASHRAE 34 
When Servicing
 Turn the power OFF at the main power box (mains) 
before opening the unit to check or repair electrical 
parts and wiring.

Keep your fingers and clothing away from any moving
parts. 
Clean up the site after you finish, remembering to check
that no metal scraps or bits of wiring have been left
inside the unit being serviced. 
 
Do not touch the air inlet or the 
sharp aluminum fins of the 
outdoor unit. You may get injured.
 Ventilate any enclosed areas when 
installing or testing the refrigeration 
system. Escaped refrigerant gas, on 
contact with fire or heat, can produce 
dangerously toxic gas. 
Confirm after installation that no 
refrigerant gas is leaking. If the gas 
comes in contact with a burning stove, 
gas water heater, electric room heater 
or other heat source, it can cause the 
generation of poisonous gas.
WA R N I N G Do not clean inside the indoor and 
outdoor units by users. Engage 
authorized dealer or specialist for 
cleaning.
 In case of malfunction of this 
appliance, do not repair by yourself. 
Contact to the sales dealer or service 
dealer for a repair.
CAUTION
CAUTION
Others

							Precautions for Installation Using New Refrigerant
1. Care regarding tubing
1-1. Process tubing
 
Material: Use C1220 phosphorous deoxidized copper specified in JIS H3300 “Copper and Copper Alloy Seamless 
Pipes and Tubes.”
 
 Tubing size: Be sure to use the sizes indicated in the table below.
Use a tube cutter when cutting the tubing, and be sure to remove any flash. This also applies to distribution joints 
(optional).
When bending tubing ø5/8 or smaller, use a bending radius that is 4 times the outer diameter of the tubing or larger.
CAUTION
Use sufficient care in handling the tubing. Seal the tubing ends with 
caps or tape to prevent dirt, moisture, or other foreign substances 
from entering. These substances can result in system malfunction.
O Material
Copper tubeOuter diameter 1/4 3/8 1/2 5/8
Wall thickness t0.032 t0.032 t0.032 t0.04Unit: inch
1-2. Prevent impurities including water, dust and oxide from entering the tubing. Impurities can cause R410A  
refrigerant deterioration and compressor defects. Due to the features of the refrigerant and refrigerating machine 
oil, the prevention of water and other impurities becomes more important than ever.
2. Be sure to recharge the refrigerant only in liquid form.
2-1.
defects of the unit.
2-2.Since R410A is a non-azeotrope, recharging the refrigerant in gas form can lower performance and cause 
Since refrigerant composition changes and performance decreases when gas leaks, collect the remaining 
refrigerant and recharge the required total amount of new refrigerant after fixing the leak.
3. Different tools required
3-1. Tool specifications have been changed due to the characteristics of R410A.
Some tools for R22- and R407C-type refrigerant systems cannot be used.

compatible 
with R410A?Remarks
Manifold gauge Yes

Yes NoTypes of refrigerant, refrigerating machine oil, and 
pressure gauge are different.
Charge hose To resist higher pressure, material must be changed.
Vacuum pump Use a conventional vacuum pump if it is equipped
with a check valve. If it has no check valve,
purchase and attach a vacuum pump adapter.
Leak detector Leak detectors for CFC and HCFC that
react to chlorine do not function because
R410A contains no chlorine. Leak detector
for HFC134a can be used for R410A. 
Flaring oil For systems that use R22, apply mineral oil (Suniso oil)
to the flare nuts on the tubing to prevent refrigerant 
leakage. For machines that use R407C or R410A, apply 
synthetic oil (ether oil) to the flare nuts. 
* Using tools for R22 and R407C and new tools for R410A together can cause defects.

3-2.  Use R410A exclusive cylinder only.
 
When charging with a refrigerant cylinder, use an 
electronic scale for charging refrigerant. In this case,
if the volume of refrigerant in the cylinder becomes 
less than 20% of the fully-charged amount, the
composition of the refrigerant starts to change. Thus, 
do not use the refrigerant if the amount in the charging 
cylinder is less than 20%. Also, charge the minimum 
necessary amount to the charging cylinder before
using it to charge the air conditioning unit.Configuration and characteristics of cylinders
Single valve
Charge liquid refrigerant with
cylinder in up-side-down position.
Single valve (with siphon tube)
Charge with cylinder in normal position.
