1. This appliance has a built-in time delay circuit to ensure reliable operation. If the operation button is pressed, the compressor will start running after a few minutes.
In the event of power failure, the unit will stop. When the power is applied, the unit will re-start automatically after 3 minutes.
2. To prevent the appliance from malfunctioning, do not set the selector knob between the two indicated positions. Make sure that it clicks into position.
This "Dual-Zone" split system cannot operate with the indoor units in different modes at the same time In other words, if one zone is in the heating mode, the other zone can also be operated in the heating mode but not in the cooling mode.
To cancel the Night Setback mode, move the selector to MANUAL.
To cancel the Night Setback mode, move the selector to MANUAL.
By selecting this mode then pressing the OPERATION ON/OFF button, the heat pump will perform cooling operation until the temperature in the room reaches the set value, then the thermostat will cause the unit to pause. After about 30 minutes, the heat pump will automatically raise the set temperature 2 °F as shown in the diagram below. This enables you to save energy without sacrificing comfort. This function is convenient for when the room is vacant or soft cooling is needed in the daytime.
By selecting this mode then pressing the OPERATION ON/OFF button, the heat pump will perform cooling operation until the temperature in the room reaches the set value, then the thermostat will cause the unit to pause.
After about 30 minutes, the heat pump will automatically raise the set temperature 2 °F. When the room temperature reaches the newly set value, the thermostat will cause the unit to pause. After about 30 minutes the temperature is again raised by 2 °F as shown below. This enables you to save energy. This function is convenient for when leaving the heat pump on all night or soft cooling is needed.
Simply set the "I" FAN SPEED selector to the "AUTO" position.
A microcomputer in the heat pump automatically controls the fan speed when the AUTO mode is selected. When the heat pump starts operating, the difference between the room temperature and the set temperature is detected by the microcomputer which then automatically switches the fan speed to the most suitable level.

This appliance has a built-in time delay circuit to ensure reliable operation. If the operation button is pressed, the compressor will start running after a few minutes. In the event of power failure, the unit will stop
In the event of power failure, the unit will stop. When the power is applied, the unit will re-start automatically after 3 minutes.
Because this heat pump heats a room by drawing in the heat of the outside air (heat pump system), the heating efficiency will fall off when the outdoor temperature is very low. If sufficient heat cannot be obtained with this heat pump, use another heating appliance in conjunction with it.
• When the outdoor temperature is low, frost or ice may form on the heat exchanger coil, reducing the heating performance. When this happens, a microcomputer defrosting system operates. At the same time, the fan on the indoor unit stops and the STANDBY LAMP remains lit until defrosting is completed. Heating operation restarts after several minutes. (This interval will vary slightly depending upon the outdoor temperature and the way in which frost forms).
This "Dual-Zone" split system cannot operate with the indoor units in different modes at the same time. In other words, if one zone is in the heating mode, the other zone can also be operated in the heating mode but not in the cooling mode.
To cancel the Energy Saver mode, move the selector to MANUAL.
To cancel the Night Setback mode, move the selector to MANUAL.
■ What does the Energy Saver mode mean ? By selecting this mode then pressing the OPERATION ON/OFF button, the heat pump will perform heating operation until the temperature in the room reaches the set value, then the thermostat will cause the unit to pause. After about half an hour, the heat pump will automatically lower the set temperature 4 °F as shown in the diagram below. This enables you to save energy without sacrificing comfort. This function is convenient for when the room is vacant or mild heating is needed in the daytime.
What does the Night Setback mode mean ? By selecting this mode then pressing the OPERATION ON/OFF button, the heat pump will perform heating operation until the temperature in the room reaches the set value, then the thermostat will cause the unit to pause.
After about 30 minutes, the heat pump will automatically lower the set temperature 4 °F. When the room temperature reaches the newly set value, the thermostat will cause the unit to pause. After about 30 minutes, the temperature is again lowered by 4 °F as shown below. This enables you to save energy. This function is convenient for when leaving the heat pump on all night or mild heating is needed.
The horizontal air flow can be adjusted by moving the vertical vane to the left or right.
Hold both ends of the flap and move the flap up and down to adjust the vertical air flow.
Recommended flap positions:
• Be sure to set the flap within zone "A".
• If the flap is set within zone "B", condensation may form near the air outlet grille and drip onto the floor.
• Set the flap within zone "B" for effective heating.
For safety's sake, be sure to turn the heat pump off and also disconnect it from the power mains before cleaning it.
Clean the casing and grille of the indoor unit with a vacuum cleaner brush, or wipe them with a clean soft cloth.
If these parts are stained, use a clean cloth moistened with a mild liquid detergent.
When cleaning the grille, be careful so as not to force the vanes out of place.
The Service TEST RUN switch is located at the rear bottom of the remote control unit. It is used for servicing the heat pump. Do not touch it, therefore. During normal operation,this switch must be set in the RUN position. If the heat pump is used with the switch in the TEST RUN position, it will not operate normally.
The air filter behind the air intake grille should be checked and cleaned at least once every two weeks.
Use a vacuum cleaner to remove light dust. If there is sticky dust on the filter, wash the filter in lukewarm, soapy water, rinse it in clean water, and dry it.
When replacing the filter, check that the FRONT mark is facing you.

The compressor start to run at Thermo ON and heating operation start, then if the room temperature is down below 3.6°F from the setting temperature, the electric heater will be ON. (When the operation button is set to ON to start heating operation, the electric heater will be ON following the compressor operation.)
• The electric heater is OFF when the operation is Thermo OFF and the compressor stop.
Fig. 2
If the indoor coil temperature falls below 30°F when the compressor has been turning for 10 minutes or more, the controller signals to stop turning to the compressor and outdoor fan. The compressor and outdoor fan motor will start to turn after 6 minutes.
Fig. 7
When the indoor coil temperature rises above 129°F, if the set speed of the indoor fan is LOW, the fan speed changes to MED. When the temperature reaches to 133°F, the outdoor fan stop to turn. When the temperature falls below 118°F, the outdoor fan turn to ON. When the temperature falls below 111°F, the indoor fan speed return to LOW from MED.
Thus the system is protected from the overload.
* When the coil temperature of either one of indoor units rises above 133°F, the outdoor fan stop to turn.
When the standby lamp lights up, the indoor fan stop, and blowout of cool air is prevented. Refer to page 18, 23 and 30.
When the capacity of unit has been decreased due to frost sticking to the outdoor heat exchanger during heating, the temperature drop gradient is detected by the microcomputer controlled temperature sensing system, and defrosting operation is started. At this time, the indoor and outdoor fan motors will stop, only the compressor is operated, and the system is automatically changed to cooling operation mode.

All wiring between indoor and outdoor units, grounding lines and disconnect switches should be provided by the installer.
Air does not function as a refrigerant because it cannot be liquefied in the condenser. Air and moisture remaining in the refrigerant system have undesirable effects as indicated at right. Therefore, they must be purged completely.
Inadequate refrigerant charge may cause freeze-up problem of the evaporator. Follow the correct air purging procedures and be sure not to overbleed refrigerant.
Quick air purge system represents purging the air stayed in the indoor unit and connection tubes by the aid of refrigerant gas charged in the outdoor unit. By this system, air purging has become much simpler and installation time has become shorter than conventional methods.
* Interval required for air purging is only 15 SECOND.
NOTE Outdoor unit is pre-charged at the factory. Don't open valves until piping is hooked up and you are ready to proceed with purging procedure.
Check that all piping and wiring have been completed correctly. Check again that wide and narrow pipe service valves are fully opened. Turn on power and run the unit.
• Valve Position -a-
The valve spindles of both wide and narrow pipes are turned all the way in. The unit is shipped from the factory in this position. (Fig. 15a)
• Valve Position -b-
The valve spindles of both wide and narrow pipes are turned all the way out ("BACK SEAT" position). This is the normal operating position. (Fig. 15-b)
• Valve Position -c-
With the narrow pipe valve kept at BACK SEAT, only the wide pipe valve spindle is turned halfwaydown position. This position is used for pressure measurement and gas charging. (Fig. 15-c)
Valve Position -d-
Like position -a-, but with the flare nut of wide pipe slack. This position is used for air purging. (Fig. 15-d)
Be sure to use the valve tool or ratchet wrench when opening or closing the shut-off valve spindle. Open Close Valve tool
Fig. 16
Pump down means collecting all refrigerant in the system back into the outdoor unit without losing refrigerant gas. Pump down is used when unit is moved or for servicing the refrigerant circuit.
6) When piping is disconnected provide dust covers for both valves and pipes until unit is reconnected.

Method to Replace Fuse on the P.C.B. Ass'y
Be sure to replace the varistor adjacent to the fuse when the fuse is blown.
Take out the fan motor connector from P.C.B. Ass'y and be sure that there is no danger of short circuit in other parts before supplying electricity to the unit. After that, supply electricity to the unit and set the selector to "MANUAL". Then, turn on the operation switch.
Now measure the voltage between these pins by the multimeter. The P.C.B. Ass'y is in good working condition if the voltage output becomes same as those shown in the below tables
