VERY IMPORTANT FOR SAFETY.
PLEASE READ THEM CAREFULLY
BEFORE INSTALLATION!

1. This air conditioner must be installed by a

certicated installer.

2. Please insure that there is an available ground in
the power supply system before installation.

3. To avoid electric shock or death, the socket
or terminal blocks for power supply to the air
conditioner(include 277V and 115V and 208-230V
series and the units that have LCDI power cord)
must have a Ground Fault Circuit Interrupter.

4. During installation, do not cross connect or reverse
L1 and neutral. Please be sure the ground wire is

rmly connected otherwise it is possible to result in

electrical shock or death.

UNIT FEATURES

This unit has many features which are different than
those found on conventional PTAC units. The servicer
must be familiar with these features in order to
property handle the unit.

• LCDI Cords - Underwriters Laboratories and the
National Electric Code (NEC) now require power
cords that sense current leakage and can open
the electrical circuit to the unit on units rated at
250 volts or less. In the event that unit does not
operate,check the reset button located on or near
the head of the power cord as part of the normal
troubleshooting procedure.

LCDI power Cord

• Automatic 3-minute compressor lockout - After
the compressor cycles off, it will not restart for three
minutes.

• Random restart delay - To help eliminate power
surges after a power outage, the unit Is equipped
with a two to four minute random restart delay
feature. Whenever the unit is plugged In with the
master switch turned on and the mode switch set in
the cool or heat mode, a random restart will occur.

• Indication LEDs - The control panel has LEDs that
correspond to fan operation and to Indicate unit

status. The LEDs next to the selections ON/OFF,

FAN, COOL, and HEAT indicate which operational
mode Is active.

• High Pressure Protection - The unit will shut off
automatically when the pressure in the system
is over 638 psi and within 10 minutes, after the
compressor turns off, the unit will restart when the
pressure turns back below 551 psi. This protection
can effectively avoid the burst and leakage of
pipes, lessen the system failures and prolong the
service life.

• Failure Tolerance - If the unit is in protection mode
less than 4 times in one hour, the accumulation
times will reset to avoid system failure. Only when
the unit enters protection mode more than 4 times in
one hour will, the system fail to restart automatically
and need manual restart.

• Standard Physical Dimensions - The series PTAC

uses standard dimensions, 42” wide x 16” high x

13-3/4” deep.

Replacement of older units is made easy.

• Weather - Protected Electrical Components

-Vital electrical components are protected from the
weather by locating them on the indoor side of the
weather barrier.

• Highly Featured Microprocessor Controls

- Microprocessor controls are programmed to

interface with the temperature sensors to maximize

comfort conditions for the room occupant.

Thermistors are used to sense small changes in

temperature to give excellent room control and

allow the microprocessor to monitor and react to
changing conditions.

• Automatic Emergency Heat on Heat Pump

Units-Automatically uses electric resistance heat if

the heat pump falls.

• High-Temperature Heat Pump Operation
Protection

-Automatically protects the compressor if heat pump
is operated with high indoor coil temperatures.
Power to the outdoor fan and the compressor
are turned off if the indoor coil gets too hot during
heat pump operation to prevent damage to the
compressor.

• Fan Motors Permanently Lubricated - All units
have two fan motors for quiet operation and

maximum operating efciency.

Motors are permanently lubricated to reduce

maintenance and totally enclosed to keep dirt and
water out of the motor windings.

• Indoor Fan Speed Selections LOW /HIGH - Unit
may be operated in low fan speed or high fan
speeds. Some speeds may not be present based
on unit capacities.

• Rotary Compressor - smoother operation for quiet,
dependable service and high efciency.

• Indoor Coil Frost Control - prevents indoor coil

from freezing. Frost can form on the Indoor coil
when the unit is operated in cooling when the
outdoor temperature is low. The unit automatically
shuts the compressor off until the indoor coil
temperature warms to the point where frosting will
no longer occur, then restarts the compressor.

ON position enables continuous fan for heating. The

default setting Is fan cycled for heating.

No. 8 -Fan CYC/CON for cooling ON position

enables fan cycle for cooling. The default setting is
fan continuous for cooling.

WARNING: Before service, you must disconnect

the power cord to avoid electric shock! Do not
reprogram DIP switches No. 1 to No. 4, when

powered this could cause damage or re. Power the

unit on again, the new function will be activated.

INJURY OR DEATH.

• LS Control (front-desk control) - The unit can
be turned ON/OFF by a front desk control switch.

The control wire, colored purple, locates in the wall
mounted thermostat interface (refer to Fig. 7 on
page 8).

The control logic as belows:

1. Turn ON unit: short circuit R and LS then release
one time within 5 seconds.

2. Turn OFF unit: short circuit R and LS then release
for twice within 5 seconds.

3. Force unit shut down for one time: connect LS to R

for over 5 seconds.
NOTE: After force shut down, you can turn the unit

ON again by hand-held remote controller or the
control panel.

• Special control functions for DIP switches - The
DIP switches are on main board. No. 5 auto

heating (for units with heat). When unit is connected
to the power supply, and room temperature Is

lower than 10°C/50°F for 3 minutes, unit will start

heating automatically no matter what the setting
mode is. Only when room temperature reaches

13°C/55°F will heating stop.

ON position enables this function.
No. 6 -Electric Power-off Memory. After power on,

the unit will run the same settings as last time.

ON position enables this function. No. 7-Fan

CON/CYC for heating.

UNIT ACCESSORIES

This unit is designed for through-the-wall installation

in new or existing buildings. To complete the

installation of this PTAC, an insulated wall sleeve and
an outdoor grille (either the stamped aluminum
grille, or the architectural grille) are required.
Consult with your distributor to acquire any optional
accessories.
The chassis and the cabinet front are shipped in one
carton.
