Set the Clock
!
CAUTION
Before you start operating the air conditioner, set the clock of the
remote control as outlined below. The clock panel on the remote
controller will display the time regardless of whether the air
conditioner is in use or not.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage.
Initial Setting of the Clock:
Handle the control with care and avoid getting the control
wet.
After batteries are inserted in the remote control, the clock panel
will display ”12:00” and begin to flash.
1. TEMP Button
IMPORTANT: The remote control can operate the unit from a
distance of up to 25 ft. (7.6 m) as long as there are no obstructions.
This is one way communication only (from remote control to fan
coil).
S

S
Press these buttons to set the time:
Y Forward
B Backward
When the timer function is used, the remote control should be kept
in the vicinity of the fan coil (within 25 ft / 7.6 m)
Each time you press the button, the time moves forward
or backward by one minute depending on which button
you press.
The remote control can perform the following basic functions:
S

Adjust airflow direction
2. CLOCK Button
When the right time is achieved, press the CLOCK button
or release Y or the B button and wait for 3 seconds, the
clock time stops flashing and the clock starts operating.
Refer to the Remote Control Function section for detailed
description of all the capabilities of the remote control.
3. Readjusting the Clock
Battery Installation
Two AAA 1.5 v alkaline batteries (included) are required for
operation of the remote control.
Press the CLOCK button on the remote control for about
3 seconds, the time of the clock display will start to flash.
To set the new time, follow 1 and 2 of ”Initial Setting of
the Clock”.
To install or replace batteries:
NOTE: Note: The time of the CLOCK must be set before the
AUTO--TIMER function will operate.
1. Slide the back cover off the control to open the battery com-
partment.
2. Insert batteries. Follow the polarity markings inside the
battery compartment.
Clock accuracy is within 15 seconds per day.
!
3. Replace battery compartment cover.
CAUTION
NOTE:
UNIT OPERATION HAZARD
1. When replacing batteries, do not use old batteries or a different
type battery. This may cause the remote control to malfunction.
2. If the remote is not going to be used for several weeks, remove
the batteries. Otherwise battery leakage may damage the remote
control.
3. The average battery life under normal use is about 6 months.
4. Replace the batteries when there is no audible beep from the
indoor unit or if the Transmission Indicator fails to light.
Failure to follow this caution may result in equipment
damage or improper operation.
Static electricity or other factors (voltage fluctuations) can
cause the remote control clock to reset. If your remote
control is reset (the time of ”12:00” flashing), set the clock
before starting the unit.

CLEANING, MAINTENANCE AND TROUBLESHOOTING
!
!
CAUTION
CAUTION
EQUIPMENT DAMAGE HAZARD
ELECTRICAL SHOCK HAZARD
Failure to follow this caution may result in equipment
damage.
When cleaning the front panel, do not use water hotter than
105_F (40.56_C) and do not pour water onto the fan coil.
Do not use abrasive or petroleum based cleaners as they
may damage the front panel.
Failure to follow this caution may result in personal injury
or death.
Always turn off power to the system before performing any
cleaning or maintenance to the system. Turn off the outdoor
disconnect switch located near outdoor unit. Be sure to
disconnect indoor unit if on a separate switch
Indoor Unit Front Panel
To clean the front panel on the indoor unit, wipe the outside with
a soft, dry cloth. If necessary, a mild liquid detergent can be applied
and wiped off with a dry cloth.
!
CAUTION
EQUIPMENT DAMAGE/OPERATION HAZARD
Failure to follow this caution may result in equipment
damage or improper unit operation.
Operating the system with dirty air filters may damage the
indoor unit and could cause reduced cooling performance,
intermittent system operation, frost build--up on indoor coil
or blown fuses.
Preparing for Extended Shutdown Period
Clean the filters and reposition them in the unit. Operate the unit
in Fan only mode for 12 hours to dry all internal parts.
Turn main power supply off and remove batteries from the remote
control.
System Operation Recommendations
The items outlined in the following list will help to assure proper
system operation:
Periodic Maintenance
Periodic maintenance is recommended to ensure proper operation
of the unit. Recommended maintenance intervals may vary
depending on the installation environment, e.g., dusty zones, etc.
Refer to Table 1.
S
Replace both remote control batteries at the same time.
S
Point the remote control toward the unit display panel when
transmitting a command.
S
S
Keep doors and windows closed while unit is operating.
!
CAUTION
Contact an authorized service representative if a problem arises
that cannot be easily resolved.
CUT HAZARD
S
S
S
Do not perform cleaning or maintenance activities while unit
is on.
Failure to follow this caution may result in personal injury.
The coil fins are very sharp. Use caution when cleaning.
Always wear safety protection.
Keep display panel on unit away from direct sunlight and heat
as this may interfere with remote control transmissions.
Cleaning the Coil
Clean the coil at the beginning of each cooling season, or when
necessary. Use a vacuum cleaner or a long--bristle brush to avoid
damage to the coil fins.
Do not block air intakes and outlets on the indoor or outdoor
units.
Energy Saving Recommendations
The following recommendations will add greater efficiency to the
ductfree system:
Air Filters
Remove and clean the air filters once a month.
NOTE: If air filters show signs of excessive wear or are torn, they
must be replaced. Contact your local dealer for replacement filters.
S
S
S
Select a comfortable thermostat setting and leave it at chosen
setting. Avoid continually raising and lowering the setting.
Keep unit filter clean. Frequent cleaning may be necessary de-
pending on indoor air quality.
1. Open front panel on unit.
Use drapes, curtains or shades to keep direct sunlight from
heating room on very hot days.
Do not obstruct air intake on front panel.
2. Pull filters down to remove.
3. Vacuum filters.
S
