Important  
When Installing  
Please Read Before Starting  
.............................................................................................  
…In a Room  
This air conditioning system meets strict safety and operating  
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.  
Properly insulate any tubing run inside a room to prevent  
“sweating” that can cause dripping and water damage to walls  
and floors.  
…In Moist or Uneven Locations  
For safe installation and trouble-free operation, you must :  
G Carefully read this instruction booklet before beginning.  
G Follow each installation or repair step exactly as shown.  
G Observe all local, state, and national electrical codes.  
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.  
G Pay close attention to all warning and caution notices  
given in this manual.  
…In a Snowy Area (for Heat Pump-type Sys-tems)  
Install the outdoor unit on a raised platform that is higher than  
drifting snow. Provide snow vents.  
This symbol refers to a hazard or  
unsafe practice which can result  
in severe personal injury or death.  
When Connecting Refrigerant Tubing  
.............................................................................................  
This symbol refers to a hazard or  
unsafe practice which can result  
in personal injury or product or  
property damage.  
G
Ventilate the room well, in the event that refrigerant gas  
leaks during the installation. Be careful not to allow contact  
of the refrigerant gas with a flame as this will cause the  
generation of poisonous gas.  
CAUTION  
G
Keep all tubing runs as short as possible.  
If Necessary, Get Help  
These instructions are all you need for most installation sites  
and maintenance conditions. If you require help for a special  
problem, contact our sales/service outlet or your certified  
dealer for additional instructions.  
G
Use the flare method for connecting tubing.  
G
Apply refrigerant lubricant to the matching surfaces of the  
flare and union tubes before connecting them, then tighten  
the nut with a torque wrench for a leak-free connection.  
In Case of Improper Installation  
G
Check carefully for leaks before starting the test run.  
The manufacturer shall in no way be responsible for improper  
installation or maintenance service, including failure to follow  
the instructions in this document.  
NOTE  
Depending on the system type, liquid and gas lines may be  
either narrow or wide. Therefore, to avoid confusion the  
refrigerant tubing for your particular model is specified as either  
“narrow” or “wide” rather than as “liquid” or “gas”.  
SPECIAL PRECAUTIONS  
When Wiring  
.............................................................................................  
ELECTRICAL SHOCK CAN CAUSE SEVERE  
PERSONAL INJURY OR DEATH. ONLY A  
QUALIFIED, EXPERIENCED ELECTRICIAN  
SHOULD ATTEMPT TO WIRE THIS SYSTEM.  
When Servicing  
..............................................................................................  
G
Turn the power OFF at the main power box (mains) before  
opening the unit to check or repair electrical parts and  
G
wiring.  
Do not supply power to the unit until all wiring and tubing are  
completed or reconnected and checked.  
G
Keep your fingers and clothing away from any moving parts.  
G
Highly dangerous electrical voltages are used in this system.  
G
Clean up the site when installation is finished. Check that no  
Carefully refer to the wiring diagram and these instructions  
when wiring. Improper connections and inadequate  
grounding can cause accidentaly injury or death.  
metal scraps or bits of wiring have been left inside the unit.  
G
Ground the unit following local electrical codes.  
CAUTION  
G
Connect all wiring tightly. Loose wiring may cause overheat-  
ing at connection points and a possible fire hazard.  
G
Ventilate any enclosed areas when installing or testing the  
refrigeration system. Contact of refrigerant gas with fire or  
heat can produce poisonous gas.  
When Transporting  
...............................................................................................  
G
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.  
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.

REMARKS: 1. Value obtained in the actual place where the unit is installed may be slightly higher than the values shown  
in this graph because of the conditions of operation, the structure of the building, the background noise and  
other factors.  
2. The test results were obtained from an nechoic room.  
NOTE  
To evaluate “Noise level” the maximum number of the measured OCTAVE BAND SOUND PRESSURE LEVEL is used.  
Read the number on each BAND CENTER FREQUENCIES (horizontal axis) ranging from 63 Hz to 8000 Hz and select the  
maximum value (vertical axis) among them.

1-9 Increasing the Fan Speed  
Electrical component box  
If external static pressure is too great (due to long extension  
of ducts, for example), the air flow volume may drop too low  
at each air outlet. This problem may be solved by increasing  
the fan speed using the following procedure:  
Jumper cable  
Fan  
motor  
Jumper cable  
Fan motor socket  
(At shipment)  
(1) Remove 4 screws on the electrical component box and  
remove the cover plate.  
(Jumper cable installed)

(2) Disconnect the fan motor sockets in the box.  
(3) Take out the jumper cable (sockets at both ends) clamped  
in the box.  
(4) Securely connect the jumper cable sockets  
between the disconnected fan motor sockets in step 2.  
(5) Place the cable neatly in the box and reinstall the cover  
plate.

How to read the diagram  
The vertical axis is the external static pressure (Pa) while the horizontal axis represents the AIR FLOW (CFM).  
The characteristic curves for HT, H, Mand Lfan speed control are shown.  
The nameplate values are shown based on the Hair flow. For the 26 type, the air flow is 636 CFM, while the  
external static pressure is 49 Pa at Hposition. If external static pressure is too great (due to long extension of  
duct, for example), the air flow volume may drop too low at each air outlet.  
This problem may be solved by increasing the fan speed as explained above.

Installing the Unit in Heavy Snow Areas  
In locations with strong wind, snow-proof ducting should  
be fitted and direct exposure to the wind should be  
avoided as much as possible.  
Countermeasures against snow and wind  
In regions with snow and strong wind, the following  
problems may occur when the outdoor unit is not  
provided with a platform and snow-proof ducting:  
Fig. 1-5  
a) The outdoor fan may not run and damage to the unit  
may occur.  
In regions with significant snowfall, the outdoor unit  
should be provided with a platform and snow-proof duct.  
b) There may be no air flow.  
c) The tubing may freeze and burst.  
d) The condenser pressure may drop because of strong  
wind, and the indoor unit may freeze.  
1
Precautions for Installation in Heavy Snow Areas  
1) The platform should be higher than the max. snow  
depth. (Fig. 1-6)  
2) The 2 anchoring feet of the outdoor unit should be  
used for the platform, and the platform should be  
installed beneath the air intake side of outdoor unit.  
3) The platform foundation must be firm and the unit  
must be secured with anchor bolts.  
Without snow-  
proof ducting  
(Low platform)  
With snow-  
proof ducting  
(High platform)  
4) In case of installation on a roof subject to strong  
wind, countermeasures must be taken to prevent the  
unit from being blown over.

General Precautions on Wiring  
1) Before wiring, confirm the rated voltage of the unit as  
shown on its nameplate, then carry out the wiring  
closely following the wiring diagram.  
7) To prevent possible hazards from insulation failure,  
the unit must be grounded.  
2) Provide a power outlet to be used exclusively for  
each unit, and a power supply disconnect and circuit  
breaker for overcurrent protection should be provided  
in the exclusive line.  
8) To prevent malfunction of the air conditioner caused  
by electrical noise, care must be taken when wiring  
as follows:  
The remote control wiring and the inter-unit  
control wiring should be wired apart from the inter-  
unit power wiring.  
3) To prevent possible hazards from insulation failure,  
the unit must be grounded.  
4) Each wiring connection must be done in accordance  
with the wiring system diagram.  
Use shielded wires for inter-unit control wiring  
between units and ground the shield on both  
sides.  
Wrong wiring may cause the unit to misoperate or  
become damaged.  
9) If the power supply cord of this appliance is dam-  
aged, it must be replaced by a repair shop appointed  
by the manufacturer, because specialpurpose tools  
are required.  
5) Do not allow wiring to touch the refrigerant tubing,  
compressor, or any moving parts of the fan.  
6) Unauthorized changes in the internal wiring can be  
very dangerous.The manufacturer will accept no  
responsibility for any damage or misoperation that  
occurs as a result of such unauthorized changes.  
10)All wiring used must be Class 1.

2-2 Cold Draft Prevention (Heating Cycle)  
The cold draft prevention function controls indoor fan speed so a strong draft of cold air will  
not blow out before the indoor heat exchange coils have warmed up.  
STANDBY shows on the remote controller when the indoor fan speed is LL (very low)  
or OFF. This condition occurs in the following 3 cases:  
During Thermo OFF (refer to 2-1 B. Room Temperature Control, Heating)  
During the defrosting operation (refer to 2-10 Defrosting Control, Heating)  
Until either the coil temperature E2 reaches 81°F or when a maximum of 6 minutes  
has past.  
The indoor fan motor operates in L instead of LL for 3 seconds as it starts to give the

Chart Summary and Explanations  
The main idea of this chart is to show that the indoor fan speed increases and gets closer to  
the set fan speed as the coil temperature E2 rises.  
The indoor unit fs coil temperature is taken from sensor E2 located in the middle of the indoor  
heat exchange coil.  
The dotted line shows that the indoor fan motor is OFF. When the temperature at sensor E2  
falls below 50 ˚F, the indoor fan motor stops running.

2. Processes and functions  
(2) If the outdoor heat exchanger temperature (C1) is  
75°F or higher continuously for 5 minutes, fan  
operation may stop (same conditions as when the  
thermostat is OFF). In this case, the fan will restart  
after 3 minutes.  
(3) This control is not performed during the 3 minutes  
after start, for 1 minute after defrost ends, and  
while defrost is in progress.  
2-4 Control Functions  
Electronic control valve control  
Opening of the electronic control valve is controlled so  
that the appropriate operating conditions are maintained,  
based on the signal from each sensor (discharge  
temperature [TD], intake temperature [TS], outdoor heat  
exchanger temperature [C1], and indoor heat exchanger  
temperature [E1, E2]).  
Coil heating control  
Discharge temperature release control  
(1) This control lowers the operating frequency of the  
compressor when electronic control valve control is  
unable to maintain the appropriate operating  
conditions because the discharge temperature fails  
to decline or because there is a sudden increase in  
the discharge temperature.  
(2) If the discharge temperature exceeds 232°F, the  
compressor is stopped and then restarted. (Error  
count = 1)  
(3) The error count is cleared when operation has  
continued for 10 minutes after the compressor was  
restarted.  
(4) If (2) repeats 4 times without the error count being  
cleared (error count = 4), alarm "P03" occurs.  
(1) This control applies current to the coil of the  
stopped compressor to heat the compressor in  
place of the crank case heater.  
(2) When the discharge temperature (TD) is less than  
77°F, the current application judgment is made  
based on the outdoor air temperature (TO).  
Current application starts when the outdoor air  
temperature drops to 59°F or below.  
Current application stops when the outdoor air  
temperature rises above 64°F.  
Control for prevention of short intermittent operation  
In order to protect the compressor, this control does not  
allow the compressor to be stopped for 10 minutes after  
operation starts, even if the thermostat OFF signal is  
received from the indoor unit.  
Control for prevention of high cooling loads  
This control reduces abnormal high-pressure increases  
during cooling operation.  
2
Current release control  
The compressor operating frequency is controlled so  
that the current that is input to the inverter compressor  
does not exceed the designated value (control value).  
(1) If MAX (C1, C2) (C1 & C2: outdoor heat exchanger  
temperature) is less than 124°F, the compressor  
performs normal operation.  
(2) If MAX (C1, C2) is 124°F or higher and less than  
142°F, the revolution of the compressor is  
controlled to prevent the high pressure being  
increased.  
(3) If MAX (C1, C2) is 142°F or higher, the compressor  
stops once. The compressor restarts three times,  
and if the temperature dose not decrease to less  
than 142°F, the alert "P20" is displayed.  
Outdoor unit fan control  
1. Cooling fan control  
(1) The outdoor unit fan minimum speed and maximum  
speed are determined according to the outdoor air  
temperature and the operating frequency.The  
speed is controlled in stages between the minimum  
speed and maximum speed, based on the outdoor  
heat exchanger temperature (C2) at that time.  
(2) For 60 seconds after start, the outdoor unit fan  
operates at maximum speed, as determined by the  
outdoor air temperature and operating frequency at  
that time. Subsequently, the fan operates at low  
speed until the outdoor heat exchanger temperature  
(C2) rises.  
142  
124  
(3) If the discharge temperature (TD) sensor is  
abnormal or has become disconnected, the fan will  
not operate and a protective device is activated.  
2. Heating fan control  
(1) The outdoor unit fan minimum speed and maximum  
speed are determined according to the outdoor air  
temperature and operating frequency.The speed is  
controlled in stages between the minimum speed  
and maximum speed, based on the outdoor heat  
exchanger temperature (C1) at that time.  
SM831148  
II-6  
2. Processes and functions  
Heating high-load control  
Overcurrent protection control  
The below control is performed during heating operation,  
based on the indoor heat exchanger temperature MAX  
(E1,E2).  
(1) If the overcurrent protection circuit detects  
abnormal current, the compressor is stopped. (Error  
count = 1.) The compressor then restarts after 3  
minutes.  
(2) If compressor start/stop is repeated 4 times (error  
count = 4), alarm "P26", "P29" or "H01" (count = 2  
in this case only) occurs. Operation stops and does  
not restart.  
(1) If the temperature is in the "M" area (operating  
frequency reduction and thermostat OFF area), the  
compressor operating frequency is reduced.  
The compressor operating frequency is reduced  
every 30 seconds as long as the temperature  
remains within this area.  
(2) If the temperature is continuously in the "M" area,  
the thermostat turns OFF.  
(3) If the temperature is in the "N" area, operating  
Current release value shift control  
(1) This control is intended to improve compressor  
reliability by preventing continuous high-frequency  
operation under overload conditions when the  
outdoor air temperature is high, and by preventing  
intermittent operation through "control for  
prevention of high cooling loads".  
(2) The control value for "current release control" is  
corrected according to the outdoor air temperature  
(TO).  
frequency increases are prohibited.  
(4) If the temperature is in the "L" area, the operating  
frequency is raised to the original frequency (the  
frequency prior to frequency reduction) by 6 Hz  
every 60 seconds.  
Depending on the temperature, the control value is  
lowered to 50 90% for cooling operation, and to  
60 98% for heating operation.  
(30, 36, 48 types)  
2
Freeze prevention (low-temperature release) control  
The below control is performed during cooling operation  
(including dehumidifying operation), using whichever of  
the indoor heat exchanger temperatures (E1 or E2) is  
lower. (See the figure below.)  
(1) If a temperature in the "J" area (operating  
frequency reduction and thermostat OFF area) is  
detected for 6 minutes, the compressor operating  
frequency is reduced.The compressor operating  
frequency is reduced every 30 seconds as long as  
the temperature remains within this area.  
(2) If the temperature is in the "K" area (operating  
frequency increase-prohibit area), the compressor  
operating frequency is maintained.  
(3) If the temperature is in the "H" area (operating  
frequency control area), and the outdoor air  
temperature is less than 90°F, the compressor  
maximum operating frequency is limited according  
to the indoor unit fan speed.  
(4) If the temperature is in the "I" area (normal  
operating area), the compressors operate normally.  
(5) If the temperature is continuously in the "J" area  
and the compressor operating frequency reaches 0,  
then temperature A (temperature for changing from  
"J" area to "H" area) is raised from 41°F to 46°F,  
and operation continues with the thermostat OFF  
until the temperature reaches the "H" area.  
* When the compressor turns ON and the E2  
temperature rises, the temperature at which the  
"M" area is first entered is 124°F (30, 36, 42  
types) or higher than 129°F (26 type).  
If the E1, E2 temperature subsequently falls to  
the "L" area, the temperature for entering the "M"  
area is raised to 126°F (30, 36, 42 types) or 133°F  
(26 type).  
However if the E1, E2 temperature falls to the "L"  
area and falls below 86°F, then the temperature for  
entering the "M" area is changed back to 124°F  
(30, 36, 42 types) or 129°F (26 type).

2-6 Outdoor Unit Control PCB (CR-CH4272R)  
(1) Explanation of Functions  
S001  
Push-button switch (black): Automatic address setting switch  
If the system address switch (S002: set to 0 at time of shipment) setting is other than  
"0" (central control), press this switch once to automatically set the addresses at all  
indoor units which are in the same system, and are connected to that outdoor unit.  
During automatic address setting, the 2 LEDs (red) on the outdoor unit control PCB  
blink alternately.  
(Pressing this switch again stops automatic address setting.)  
If automatic address setting is currently in progress at another system that is subject  
to central control, only LED 1 on the outdoor unit control PCB blinks to indicate that  
automatic address setting is in progress at another unit. If automatic address setting is  
in progress at another unit, automatic address setting cannot be started at this unit,  
even if S001 is pressed.  
Rotary switch (10 positions, black): System address setting switch  
This switch is set to 0 (1 system control) at the time of shipment. However the address  
for each system must be set when multiple systems are controlled or when central  
control is used. (Figure 1)  
S002  
If the system address is set to 0, automatic address setting is started when the power is  
turned ON. Therefore it is not necessary to use switch SW01 and perform automatic  
address setting in the case of single or simultaneous-operation multi control of a single  
system.  
When using central control for multiple systems, a maximum of 30 systems (maximum  
64 units) can be connected. In the case of group control or central control, set the sys-  
tem address to a setting other than 0 (1 or above).  
If the number of systems is greater than 9, this switch can be used in combination with  
DIP switch S003 to set up to 30 systems. The setting can be made as high as 39,  
however all settings above 30 are handled as 30 for control. (For details, refer to Table 1.)  
If system addresses are duplicated (the same address exists more than once), LED 1 on  
the outdoor unit control PCB lights up, and alarm "L04" is displayed on the remote con-  
troller.  
2
DIP switch (2P, blue): System address 10s-digit and 20s-digit place setting switch  
When setting 10 systems or more, set this switch in combination with S002.  
For 10 19 systems, set 1P (10s-digit place) to ON.  
For 20 29 systems, set 2P (20s-digit place) to ON, and set 1P (10s-digit place) to OFF.  
For 30 systems, set both 1P (10s-digit place) and 2P (20s-digit place) to ON. (For details,  
refer to Table 1.)  
S003  
S005  
Refrigerant recovery switch (red button switch)  
Press this switch to perform refrigerant recovery control using cooling operation. The  
indoor unit fan will operate at HIGH and 55 Hz for a maximum of 10 minutes. When  
refrigerant recovery is completed, close the valves and press this switch to stop the  
operation.

2. Processes and functions  
Terminal plug  
(CN015)  
3P plug (black): Terminal plug for the communications line  
At the time of shipment from the factory, the short-circuiting socket (2P, black) is  
installed between pins 1 and 2 on the terminal plug (terminal = yes).  
When central control is used for multiple systems, leave the short-circuiting socket in  
place only on the outdoor unit with a system address of 1. At all other outdoor units  
(other than unit No. 1), move the short-circuiting socket to between 2 and 3 (terminal =  
no). If multiple short-circuiting sockets remain in place during central control, a com-  
munications failure will occur.  
In the case of a single system only (system address = 0), do not remove the short-  
circuiting socket. (Alarm "E04" will occur.)  
Quiet mode  
(CN028)  
2P plug (white): Enables operation in quiet mode.  
The outdoor unit fan and compressor frequencies are subject to limits during operation.  
Low-noise operation is enabled when the relay is turned ON.

5. Outdoor unit maintenance remote control  
5-1. Overview  
What is the outdoor unit maintenance remote controller?  
Beginning with the DC-INV series of outdoor units, nonvolatile memory (EEPROM) is  
used in the outdoor unit PCB. In this way, the setting switches that were located on  
earlier PCBs have been converted to EEPROM data.This remote controller is an  
outdoor unit maintenance tool that is used to make and change the EEPROM set-  
tings.  
This remote controller can be used for checking the outdoor unit EEPROM settings  
and contents, and also can be used to monitor the outdoor unit alarm history and  
indoor/outdoor unit temperatures, and to check the status of the indoor unit connec-  
tions (No. of units, operating status, etc.).  
Note: Because this tool does not function as a remote controller, it is used only  
during test runs and servicing.

6-6. Precautions  
RCS-TM80BG  
Request that the customer be present when the test run is performed. At this time, explain the operation manual  
and have the customer perform the actual steps.  
Be sure to pass the manuals and warranty certificate to the customer.  
Check that the AC 230 / 208 V power is not connected to the inter-unit control wiring connector terminal.  
*
If AC 230 / 208 V is accidentally applied, the indoor or outdoor unit control PCB fuse (0.5A for both indoor  
and outdoor units) will blow in order to protect the PCB. Correct the wiring connections, then disconnect the  
2P connectors (indoor: blue, OC) (outdoor: blue, OC) that are connected to the PCB, and replace them with  
2P connectors (indoor: brown, EMG) (outdoor: brown, EMG). (Refer to the figure below.) If operation is still not  
possible after changing the brown connectors, try cutting the varistor (VA002) (both indoor and outdoor).  
(Be sure to turn the power OFF before performing this work.)
