MULTI-ZONE OPERATION
The Multi-Zone mini-split will operate each zone in either cooling or heating mode but not both. The
unit will not operate as one zone cool and another heat. If this occurs, an E7 error will be displayed. To
clear this error, make sure all indoor units are in the same mode either heat or cool. Each zone will
control the room temperature at set-point and allow all normal fan, swing, turbo, timer, and sleep
functions.
Notes:
1. Indoor fan does not turn off in the cooling mode when temperature set point has been satisfied. It
will continue to run to keep the room temperature consistent.
2. Indoor fan will turn off in heating mode when temperature set point has been satisfied.
3. Unit may require several minutes to confirm the condition of temperature set point and system
functions.

REMOTE CONTROL FUNCTIONS
Note: Be sure there are no obstructions between the remote control and the receiver. Remote control
units are interchangeable, and are not assigned to a particular indoor unit. Indoor controller will beep
each time it receives a command from the remote control. Keep the remote control away from moisture
and excessive heat.TIP: Each remote will control any or all the indoor units.
ON/OFF -Turns the unit on or off. There is a 3 minute compressor delay when the unit is turned on.
MODE –Pressing the MODE button will select between AUTO, COOL, DRY, FAN, or HEAT (for Heat
Pump units only).
AUTO mode - Set point temperature will not be shown on the remote control display and
cannot be changed. Temperature is automatically set to 68 °F to 77 °F and will switch between
COOL, HEAT or FAN mode to maintain the temperature. If the temperature goes below 68 °F
the unit will switch to HEAT mode. If the temperature goes above 77 °F unit switches to COOL
mode. If temperature is in between the temperatures it runs in the FAN mode.
On rare occasions while running in the AUTO mode with other zones activated there may be
an “E7” error code. “E7” error code occurs when 2 or more units are set to run in different
modes, such as HEAT and COOL. In the AUTO mode the unit automatically switches between
HEAT, COOL or FAN. If other zones are set to HEAT or COOL while the AUTO is running in
an opposite mode an “E7” will occur. To rectify this condition you must set all the indoor units
to the same mode, either HEAT or COOL, or leave the unit alone and when the temperature
returns to the point where the unit switches back to the correct mode (as the other indoor units)
and all zones are in the HEAT or COOL mode, it will clear itself and begin to run again.
COOL mode –Unit cools room to set point temperature. Set point temperature can be set from
61 °F to 86 °F. Outdoor unit will operate in outside temperatures of +4 to +118 ºF in the cooling
mode. Indoor fan does not turn off in the cooling mode when temperature set point has been
satisfied. It will continue to run to keep the room temperature consistent.
HEAT mode (for Heat Pump units only) - Unit heats room to set point temperature. Set point
temperature can be set from 61 °F to 86 °F. Outdoor unit will operate in outside temperatures
of -5 ºF to +75 ºF in the heating mode. Indoor fan will turn off in heating mode when
temperature set point has been satisfied.
DRY mode –Set point temperature can be set from 61°F to 86°F. Unit cools at 90% capacity
while the FAN runs in LOW speed only (FAN speed cannot be changed).
FAN mode –Selects fan only operation. Set point temperature can be set from 61 °F to 86 °F.
Fan speed can be set to AUTO, HIGH, MEDIUM or LOW.
SLEEP –In the COOL mode adjust the set-point temperature to a comfortable setting, and then
press the SLEEP button. After 1 hour, the set-point will increase by 1.8 ºF (1 ºC). After 2 hours have
passed temperature is increased by 3.6 ºF (2 ºC). Temperature will never increase more than 3.6 ºF (2
ºC) from set-point or beyond 86 ºF (30 ºC). The temperature will stay at this setting until the unit is
turned off or the SLEEP function is disabled.
In the HEAT mode adjust the set-point temperature to a comfortable setting, and then press the
SLEEP button. After 1 hour the set-point will decrease by 1.8 ºF (1 ºC). After 2 hours have passed
temperature is decreased by 3.6 ºF (2 ºC). Temperature will never decrease more than 3.6 ºF (2 ºC)
from set point or below 61 ºF (16 ºC). The temperature will stay at this setting until the unit is turned off
or the SLEEP function is disabled.
The SLEEP mode does not work in the FAN or AUTO modes and is deactivated when the unit is
turned off or power is lost. On power up, the SLEEP mode must be turned on again if needed. Press
the SLEEP mode button to toggle SLEEP mode off and return to normal operation.
FAN –Press this button to change fan speeds, AUTO, HIGH, MEDIUM or LOW, while in the
HEAT, COOL, FAN modes. When in the AUTO setting, the fan will run faster the further away from the
set point it gets. On the other hand the closer it gets to the set point the slower it will run.
CLOCK –Press the CLOCK button, the clock ICON will start to blink. It will only blink for 5
seconds. While blinking press and hold down the + or - keys to adjust the 24H time of day clock to the

950-0207revB - 10 - March 2, 2016

CONNECTION PIPING
Flaring the pipe end
Cut the pipe end with a pipe cutter.
1. Remove burrs with the cut surface facing downward so that the chips do not enter the pipe.
2. Fit the flare nut on the pipe.
3. Flare the pipe.
4. Check flaring is properly done.
CAUTION!
●Don not use mineral oil on flare part. Prevent mineral oil from getting into the system as this would
reduce the lifetime of the unit.
●Never use piping which had been used for previous installations.
●Never install a drier to this R410A unit in order to guarantee the lifetime.
●Poor flaring may cause refrigerant gas leakage.

5. The bending angle of the pipe cannot be too small; otherwise it will crack. And please use a pipe
tube bender to bend the pipe.
6. Wrap the exposed refrigerant pipe and the joints by sponge and then tighten them with the plastic
tape.
CAUTION:
1. During the connection of the indoor unit and the refrigerant pipe, never pull any joints of the indoor
unit by force; otherwise the capillary pipe or other pipe may crack, which then would result in
leakage.
2. The refrigerant pipe should be supported by brackets, that is, don’t let the unit withstand the
weight of it.
If the specification of the outdoor unit pipe joint does not conform to that of the indoor unit, then
the joint specification of the outlet pipe of the indoor unit takes precedence. A reducing nipple
(adapter) shall be installed at the joint of the outdoor unit so as to make the joint of the outdoor
unit compatible with that of the indoor unit.
INSULATION FOR THE REFRIGERANT PIPE
1. The refrigerant pipe should be insulated by the insulating material and plastic tape in order to
prevent condensation and water leakage.
2. The joints of the indoor unit should be wrapped with the insulating material and no gap is allowed
on the joint of the indoor unit. See Fig. 18 below.
No gap
CAUTION:
After the pipe is protected will enough, never bend it to form a small angle; otherwise it would
crack or break.
3. Wrap the pipe with tape.
a. Bundle the refrigerant pipe and electric wire together with tape, and separate them from the
drain pipe to prevent the condensate water overflowing.
b. Wrap the pipe from the bottom of the outdoor unit to the top of the pipe where it enters the wall.
During the wrapping, the later circle should cover half of the former one.
c. Fix the wrapped pipe on the wall with clamps.
CAUTION:
●Do not wrap the pipe too tightly; otherwise the insulation effect would be weakened. Additionally,
make sure the drain hose is separated from the pipe.
●After that, fill the hole on the wall with sealing material to prevent wind and rain coming into the room.
●If the specification of the outdoor unit pipe joint does not conform to that of the indoor unit, then the
joint specification of the outlet pipe of the indoor unit takes precedence. An adapter shall be installed at
the joint of the outdoor unit so as to make the joint of the outdoor unit compatible with that of the indoor
unit. For detail information, please refer to the installation manual to be placed in the outdoor unit
carton.
