IMPORTANT! 
Please Read Before Starting
This air conditioning system meets strict safety and oper-
ating standards. As the installer or service person, it is an 
important part of your job to install or service the system so 
it operates safely and efficiently. 
For safe installation and trouble-free operation, you must:
Carefully read this instruction booklet before beginning.
Follow each installation or repair step exactly as shown.
Observe all local, state, and national electrical codes.
Pay close...

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-...

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...

iv
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...
