AIR CONDITIONER FEATURES

Memory

The unit has memory. If power is lost, all of the control

settings (mode, fan speed, on / o󰀨 and conguration) are

remembered. When power is restored, the unit will start

back up in the mode (and conguration) it was in when

power was lost.

Automatic Evaporator Freeze Protection

The compressor is turned o󰀨 automatically to keep the

evaporator from freezing and the indoor fan is turned on
when the evaporator temperature is too low. If the evapora-

tor temperature is not too low, this function is turned o󰀨.

Automatic Quick Warm-up
(For Heat Pump Models Only)

If the room temperature falls 4.5°C / 8°F below the set point

temperature, the reverse cycle heat is shut o󰀨, and the

electric strip heat is turned on for one cycle until heating is

satised.

LED Indicators and Buttons

INSTALLATION

How to Install the Unit:

CAUTION

There are sharp edges that can cause serious cuts. When
lifting the air conditioner, it is HEAVY. Use two people to lift.

CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment dam­age or improper operation. Improper wiring may damage unit
electronics. Common busing is not permitted. Damage or
erratic operation my result.

Use terminal 4-way for heat pump connection only. Sug­gested set compressor protection time is more than 3
minutes in the wall thermostat. If set less than 3 minutes,
the compressor will restart delay 3 minutes still.

Wall Thermostat must be heating changeover 4-way valve.
For thermostats that have only one fan speed output (on
or auto), the fan speed is determined by how the terminal
connector is wired. If Low fan is desired, wire the G output
from the thermostat to (LOW-FAN) on the units terminal
block. If High fan is desired, wire the G output from the
thermostat to (HI-FAN) on the units terminal block.

The range of set temperature of wall thermostat must be
in consonance with the range of DIP switch setting. Wall
Thermostat must be set the type properly in consonance
with the unit type: heat pump or no heat pump.

• For existing sleeve, you should measure the wall
sleeve dimensions.

• Install the new air conditioner according to these in­stallation instructions to achieve the best performance.
All wall sleeves used to mount the new air conditioner
must be in good structural condition and have a rear

grille that securely attaches to the sleeve or the ange

of the sleeve to secure the new air conditioner.

• To avoid vibration and noise, make sure the unit is

installed securely and rmly.

• When installing the sleeve,make certain there is noth­ing within 20 of the back that would interfere with heat

radiation and exhaust air ow. (See Figure 6)

If the Wall Thermostat has only one electrical heater output,
connect the two terminals of HEAT 1 and HEAT 2, the unit
can operate two electrical heaters (only for the unit has two
electrical heaters). Otherwise operate one electrical heater.

the air inside the room is circulated and filtered.
When set at OPEN, some outdoor air will be drawn
into room. This will reduce heating or cooling
efficiency.

Lift unit level and slide unit into wall sleeve until rmly

against front of wall sleeve and secure with 4 screws and
washers (supplied in the SLEEVE ASSEMBLY) through the

unit ange holes. (See Figure 11 and Figure 12)

CARE AND CLEANING

Front Panel and Case

Turn unit o󰀨 and disconnect power supply. To clean, use

water and a mild detergent. DO NOT use bleach and abra­sivers. Some commercial cleaners may damage the plastic
parts.

Outdoor Coil

Coil on outdoor side of unit should be checked regularly.
Unit will need to be removed to inspect dirt build-up that will
occur on the inside of the coil. If clogged with dirt and soot,
coil should be professionally cleaned. Clean inside and
outside of outdoor coils regularly.

NOTE: Never use a high-pressure spray on coil.

CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment dam­age or improper operation. Airflow restriction may cause
damage to the unit.

Air Filters
IMPORTANT: Turn unit off before cleaning.

CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment dam­age or improper operation. Do not operate unit without fil­ters in place. If a filter becomes torn or damaged, it should
be replaced immediately. Operating without filters in place
or with damaged filter will allow dirt and dust to reach in­door coil and reduce cooling, heating, airflow and efficiency
of unit. Airflow restriction may cause damage to unit.

Vent Door Filter
IMPORTANT: TURN UNIT OFF BEFORE CLEANING.

• If the vent door is open, access requires the removal of

the unit from the wall sleeve. Clean the vent lter twice

a year or as required.

• Make sure to remove the shipping screw from the vent
door (See Figure 9).

• Rotate the vent control lever to open the vent door
(See Figure 16).

• Remove four screws from the vent door lter (See
Figure 16).

• First pull out the vent door steel wire from the hole of

the vent door, then take o󰀨 the vent door and lter (See

Figure 16).

• Clean the lter. Dry thoroughly before replacing.

• Replace the vent door and lter,reinstall the four
screws.

• Reinsert the vent door steel wire into the hole of the
vent door.

The most important thing you can do to maintain unit

e󰀩ciency is to clean the lters once every two weeks as re­quired. Clogged lters reduce cooling, heating, and airow.

Keeping lters clean will:

• Decrease cost of operation.

• Save energy.

• Prevent clogged indoor coil.

• Reduce risk of premature component failure.

To Clean Air Filters:

• Vacuum o󰀨 heavy soil.

• Run water through lter.

• Dry thoroughly before replacing.

UNIT NOT IN COOLING / HEATING ROOM

· Make sure that curtains, blinds, or furniture are not restricting or blocking
unit air flow.

· Unit air discharge section is blocked

· Reset to a lower or higher temperature setting.

· Temperature setting is not high or low enough

· Remove and clean filters.

· Allow sufficient amount of time for unit to heat or cool the room. Start

heating or cooling early before outdoor temperature, cooking heat or

gatherings of people make room uncomfortable.

· Unit air filters are dirty.

· Close vent door.

· Check dip switch and wall thermostat settings for desired comfort.

· Vent door left open.

· Wait approximately 3 minutes for compressor to start.

· Unit may be in protection mode.

· Compressor is in time delay.

· The unit may be in a protection mode.

· The unit may be set for °C (instead of °F).

UNIT MAKING NOISES

· Clicking, gurgling, and whooshing noises are normal during operation of

unit.

WATER DRIPPING OUTSIDE

· If a drain kit has not been installed, condensation runoff during very hot

and humid weather is normal. See note 2. If a dran kit has been installed
and is connected to a drain system, check gaskets and fittings around drain
for leaks and plugs.

WATER DRIPPING INSIDE

· Wall sleeve is not installed level

· Wall sleeve must be installed level for proper drainage of condensation.

Check that installation is level and make any necessary adjustments.

DISPLAY HAS STRANGE NUMBERS / CHARACTERS
ON IT

POSSIBLE CAUSES

· Room is excessively hot or cold when unit is
started.

NOTE: Setpoint limits may not allow the unit to heat

or cool the room to the temperature desired. Check

section on dip switch settings

· Unit may have become unplugged

TROUBLESHOOTING

SOLUTIONS

· When outdoor temperature is approximately 55°F or below, frost may form on

the indoor coil when unit is in Cooling Mode. Switch unit to FAN operation until ice

or frost melts.

· Remove and clean filters

· Random Compressor restart - Whenever the unit is plugged in, or power has been

restarted, a random restart will occur. After a power outage, the compressor will

restart after approximately 3 minutes.

· Compressor Protection - To prevent short cycling of the compressor, there is a

random startup delay of 3 minutes and a minimum compressor run time of 3
minutes.

· Clean the evaporator once every three months by professional people.

NOTES:

1. If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician,

2. If unit is installed where condensation drainage could drip in an undesirable location, an accessory drain kit should be

installed and connected to drain system.

· Dirty filters

· Low outdoor temperature

ICE OR FROST FORMS ON INDOOR COIL

· Power may have cycled, so compressor is in a restart

protection.
