CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R410A
Charge refrigerant from liquid phase of gas
cylinder.
If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.
Do not use refrigerant other than R410A.
If other refrigerant (R22, etc.) is used, chlorine in refrige-
rant can cause deterioration of refrigerant oil, etc.
Use a vacuum pump with a reverse flow check
valve.
Vacuum pump oil may flow back into refrigerant cycle and
that can cause deterioration of refrigerant oil, etc.
Use the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Handle tools with care.
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com-
pressor.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigera-
nt will change and the efficiency will be lowered.
Flare tool
Electronic refrigerant
charging scale
Vacuum pump adaptor
Size adjustment gauge
Gauge manifold
Torque wrench
Gas leak detector
Charge hose
Tools for R410A
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com-
pressor.
If large amount of mineral oil enters, that can cause deterio-
ration of refrigerant oil, etc.
Do not use the existing refrigerant piping.
The old refrigerant and lubricant in the existing piping
contains a large amount of chlorine which may cause the
lubricant deterioration of the new unit.
Use “low residual oil piping”
If there is a large amount of residual oil (hydraulic oil, etc.)
inside the piping and joints, deterioration of the lubricant
will result.
Store the piping indoors, and keep both ends of
the piping sealed until just before brazing.
(Leave elbow joints, etc. in their packaging.)
The refrigerant oil applied to flare and flange
connections must be ester oil, ether oil or
alkylbenzene oil in a small amount.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.
Use the specified refrigerant only.
SAFETY PRECAUTION

OCHT746A 3
[1] Cautions for service
(1) Perform service after recovering the refrigerant left in unit completely.
(2) Do not release refrigerant in the air.
(3) After completing service, charge the cycle with specified amount of refrigerant.
(4) When performing service, install a filter drier simultaneously.
Be sure to use a filter drier for new refrigerant.
[2] Additional refrigerant charge
When charging directly from cylinder
· Check that cylinder for R410A on the market is a syphon type.
· Charging should be performed with the cylinder of syphon standing vertically. (Refrigerant is charged from liquid phase.)
Electronic weighing scale
Unit
[3] Service tools
Use the below service tools as exclusive tools for R410A refrigerant.
No. Tool name Specifications
1Gauge manifold
· Only for R410A
· Use the existing fitting specifications. (UNF1/2)
· Use high-tension side pressure of 768.7 PSIG [5.3 MPa.G] or over.
2Charge hose · Only for R410A
· Use pressure performance of 738.2 PSIG [5.09 MPa.G] or over.
3Electronic weighing scale
4Gas leak detector · Use the detector for R134a, R407C or R410A.
5Adaptor for reverse flow check · Attach on vacuum pump.

44-WAY AIRFLOW SYSTEM
4-1. PLACEMENT OF THE AIR OUTLETS
• For this grille, the blowout direction comes in 11 patterns.
Also, by setting the remote controller to the appropriate settings, you can adjust the airflow and speed. Select the settings
from Table1 according to the location in which you want to install the unit.
1) Decide on the pattern of the airflow direction.
Blowout direction
pattern
4-direction<Table 1> 3-direction 2-direction
Note: For 3 and 2-direction settings, please use the air outlet shutter plate (option).
Pattern 1 Initial setting Pattern 4 One air outlet
fully closed
Pattern 6 2 air outlet
fully closed
2) According to the number of air outlets and height of the ceiling to install the unit, be sure to set up the switch (SW21) on
the indoor controller board to the appropriate setting.
• Correspondence of ceiling heights to numbers of air outlets

DUCT FAN (Booster fan)
• Whenever the indoor unit is operating, the duct fan also
operates.
(1) Connect the optional multiple remote controller adapter
(PAC-SA88HA-E) to the connector CN51 on the indoor
controller board.
(2) Drive the relay after connecting the 12 VDC relay
between the Yellow and Orange connector lines.

At the time of installation, use the duct holes (cut out) located at the positions shown in following diagram, as and when required.
• A fresh air intake hole for the optional multi function casement can also be made.
Note:
When installing the optional multi function casement, add 5-5/16” (135 mm) to the dimensions marked on the figure.
When installing the branch ducts, be sure to insulate adequately.
Otherwise, condensation and dripping may occur.
