6. Information on servicing:
1) Checks to the area:
Prior to beginning work on systems containing flammable refrigerants,
safety checks are necessary to ensure that the risk of ignition is minimized.
For repair to the refrigerating system, the following precautions shall be
complied with prior to conducting work on the system.
2) Work procedure:
Work shall be undertaken under a controlled procedure so as to minimize
the risk of a flammable gas or vapor being present while the work is being
performed.
3) General work area:
All maintenance staff and others working in the local area shall be
instructed on the nature of work being carried out. Work in confined spaces
shall be avoided. The area around the workspace shall be sectioned off.
Ensure that the conditions within the area have been made safe by control
of flammable material.
4) Checking for presence of refrigerant:
The area shall be checked with an appropriate refrigerant detector prior to
and during work, to ensure the technician is aware of potentially flammable
atmospheres. Ensure that the leak detection equipment being used is
suitable for use with flammable refrigerants, i.e. non-sparking, adequately
sealed or intrinsically safe.
5) Presence of fire extinguisher:
If any hot work is to be conducted on the refrigeration equipment or
any associated parts, appropriate fire extinguishing equipment shall be
available to hand. Have a dry powder or CO2 fire extinguisher adjacent to
the charging area.
6) No ignition sources:
No person carrying out work in relation to a refrigeration system which
involves exposing any pipe work that contains or has contained flammable
refrigerant shall use any sources of ignition in such a manner that it may
lead to the risk of fire or explosion. All possible ignition sources, including
cigarette smoking, should be kept sufficiently far away from the site of
installation, repairing, removing and disposal, during which flammable
refrigerant can possibly be released to the surrounding space. Prior
to work taking place, the area around the equipment is to be surveyed
to make sure that there are no flammable hazards or ignition risks. No
Smoking signs shall be displayed.
7) Ventilated area:
Ensure that the area is in the open or that it is adequately ventilated
before breaking into the system or conducting any hot work. A degree
of ventilation shall continue during the period that the work is carried
out. The ventilation should safely disperse any released refrigerant and
preferably expel it externally into the atmosphere.
8) Checks to the refrigeration equipment:
Where electrical components are being changed, they shall be fit for the
purpose and to the correct specification. At all times the manufacturer’s
maintenance and service guidelines shall be followed. If in doubt consult
the manufacturer’s technical department for assistance. The following
checks shall be applied to installations using flammable refrigerants:
a. The charge size is in accordance with the room size within which the
refrigerant containing parts are installed;
b. The ventilation machinery and outlets are operating adequately and are
not obstructed;
c. If an indirect refrigerating circuit is being used, the secondary circuit
shall be checked for the presence of refrigerant; Marking to the equipment
continues to be visible and legible. Markings and signs that are illegible
shall be corrected;
d. Refrigeration pipe or components are installed in a position where they
are unlikely to be exposed to any substance which may corrode refrigerant
containing components, unless the components are constructed of
materials which are inherently resistant to being corroded or are suitably
protected against being so corroded.
9) Checks to electrical devices:
Repair and maintenance to electrical components shall include initial
safety checks and component inspection procedures. If a fault exists that
could compromise safety, then no electrical supply shall be connected to
the circuit until it is satisfactorily dealt with. If the fault cannot be corrected
immediately but it is necessary to continue operation, an adequate
temporary solution shall be used. This shall be reported to the owner of
the equipment so all parties are advised. Initial safety checks shall include:
a. That capacitors are discharged: this shall be done in a safe manner to
avoid possibility of sparking;
b. That there no live electrical components and wiring are exposed while
charging, recovering or purging the system;
c. That there is continuity of earth bonding.
6
7. Repair to intrinsically safe components:
Do not apply any permanent inductive or capacitance loads to the circuit
without ensuring that this will not exceed the permissible voltage and
current permitted for the equipment in use. Intrinsically safe components
are the only types that can be worked on while live in the presence of a
flammable atmosphere. The test apparatus shall be at the correct rating.
Replace components only with parts specified by the manufacturer. Other
parts may result in the ignition of refrigerant in the atmosphere from a
leak.
8. Cabling:
Check that cabling will not be subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse environmental
effects. The check shall also take into account the effects of aging or
continual vibration from sources such as compressors or fans.
9. Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the
searching for or detection of refrigerant leaks. A halide torch (or any other
detector using a naked flame) shall not be used.
10. Leak detection methods:
The following leak detection methods are deemed acceptable for systems
containing flammable refrigerants. Electronic leak detectors shall be used
to detect flammable refrigerants, but the sensitivity may not be adequate,
or may need re-calibration. (Detection equipment shall be calibrated in a
refrigerant-free area.) Ensure that the detector is not a potential source of
ignition and is suitable for the refrigerant used. Leak detection equipment
shall be set at a percentage of the LFL of the refrigerant and shall be
calibrated to the refrigerant employed and the appropriate percentage of
gas (25 % maximum) is confirmed. Leak detection fluids are suitable for
use with most refrigerants but the use of detergents containing chlorine
shall be avoided as the chlorine may react with the refrigerant and corrode
the copper pipe-work. If a leak is suspected, all naked flames shall be
removed/extinguished. If a leakage of refrigerant is found which requires
brazing, all of the refrigerant shall be recovered from the system, or
isolated (by means of shut off valves) in a part of the system remote from
the leak. Oxygen free nitrogen (OFN) shall then be purged through the
system both before and during the brazing process.
11. Removal and evacuation
When breaking into the refrigerant circuit to make repairs or for any other
purpose conventional procedures shall be used. However, it is important
that best practice is followed since flammability is a consideration. The
following procedure shall be adhered to: Remove refrigerant; Purge the
circuit with inert gas; Evacuate; Purge again with inert gas; Open the
circuit by cutting or brazing. The refrigerant charge shall be recovered into
the correct recovery cylinders. The system shall be flushed with OFN to
render the unit safe. This process may need to be repeated several times.
Compressed air or oxygen shall not be used for this task. Flushing shall be
achieved by breaking the vacuum in the system with OFN and continuing
to fill until the working pressure is achieved, then venting to atmosphere,
and finally pulling down to a vacuum. This process shall be repeated until
no refrigerant is within the system. When the final OFN charge is used, the
system shall be vented down to atmospheric pressure to enable work to
take place. This operation is absolutely vital if brazing operations on the
pipe-work are to take place. Ensure that the outlet for the vacuum pump is
not close to any ignition sources and there is ventilation available.
12. Charging procedures:
In addition to conventional charging procedures, the following
requirements shall be followed. Ensure that contamination of different
refrigerants does not occur when using charging equipment. Hoses or
lines shall be as short as possible to minimize the amount of refrigerant
contained in them. Cylinders shall be kept upright. Ensure that the
refrigeration system is earthed prior to charging the system with
refrigerant. Label the system when charging is complete (if not already).
Extreme care shall be taken not to overfill the refrigeration system. Prior
to recharging the system it shall be pressure tested with OFN. The system
shall be leak tested on completion of charging but prior to commissioning.
A follow up leak test shall be carried out prior to leaving the site.
13. Decommissioning:
Before carrying out this procedure, it is essential that the technician
is completely familiar with the equipment and all its detail. It is
recommended good practice that all refrigerants are recovered safely.
Prior to the task being carried out, an oil and refrigerant sample shall be
taken in case analysis is required prior to re-use of reclaimed refrigerant.
It is essential that electrical power is available before the task is
commenced.
a. Become familiar with the equipment and its operation.
b. Isolate system electrically.
c. Before attempting the procedure ensure that: Mechanical handling
equipment is available, if required, for handling refrigerant cylinders;
All personal protective equipment is available and being used correctly;
The recovery process is supervised at all times by a competent person;
Recovery equipment and cylinders conform to the appropriate standards.
d. Pump down refrigerant system, if possible.
e. If a vacuum is not possible, make a manifold so that refrigerant can be
removed from various parts of the system.
f. Make sure that cylinder is situated on the scales before recovery takes
place.
g. Start the recovery machine and operate in accordance with
manufacturer’s instructions.
h. Do not overfill cylinders. (No more than 80 % volume liquid charge).
i. Do not exceed the maximum working pressure of the cylinder, even
temporarily.
j. When the cylinders have been filled correctly and the process completed,
make sure that the cylinders and the equipment are removed from site
promptly and all isolation valves on the equipment are closed off.
k. Recovered refrigerant shall not be charged into another refrigeration
system unless it has been cleaned and checked.
14. Labeling:
Equipment shall be labeled stating that it has been de-commissioned
and emptied of refrigerant. The label shall be dated and signed. Ensure
that there are labels on the equipment stating the equipment contains
flammable refrigerant.
15. Recovery:
When removing refrigerant from a system, either for servicing or
decommissioning, it is recommended good practice that all refrigerants
are removed safely. When transferring refrigerant into cylinders, ensure
that only appropriate refrigerant recovery cylinders are employed. Ensure
that the correct number of cylinders for holding the total system charge
is available. All cylinders to be used are designated for the recovered
refrigerant and labeled for that refrigerant (i.e. special cylinders for the
recovery of refrigerant).
Cylinders shall be complete with pressure relief valve and associated shut-
off valves in good working order. Empty recovery cylinders are evacuated
and, if possible, cooled before recovery occurs. The recovery equipment
shall be in good working order with a set of instructions concerning
the equipment that is at hand and shall be suitable for the recovery of
flammable refrigerants. In addition, a set of calibrated weighing scales
shall be available and in good working order. Hoses shall be complete
with leak-free disconnect couplings and in good condition. Before using
the recovery machine, check that it is in satisfactory working order, has
been properly maintained and that any associated electrical components
are sealed to prevent ignition in the event of a refrigerant release. Consult
manufacturer if in doubt. The recovered refrigerant shall be returned to
the refrigerant supplier in the correct recovery cylinder, and the relevant
Waste Transfer Note arranged. Do not mix refrigerants in recovery units
and especially not in cylinders. If compressors or compressor oils are to
be removed, ensure that they have been evacuated to an acceptable level
to make certain that flammable refrigerant does not remain within the
lubricant. The evacuation process shall be carried out prior to returning
the compressor to the suppliers. Only electric heating to the compressor
body shall be employed to accelerate this process. When oil is drained
from a system, it shall be carried out safely.
NOTE: Check the appliance regularly and refer to TROUBLESHOOTING or
contact our customer support if it shows any of the following signs:
- Power cord or plug is damaged.
- Loud noise, unusual smell or excessive heat.

A.6 Unit Features
This Premium unit has many exciting features which are different than those found on standard PTAC models. The owner must be
familiar with these features in order to fully understand the operation and capability of the unit.
Intelligence–Your Premium unit has an on board computer that utilizes real time diagnostics to prolong the life of your unit. There is
an LED indicator on the control board, behind the front panel, that will flash an error code if the unit has detected some kind of fault condition.
In many cases, the unit will automatically clear the fault condition and continue operating with no interruption. In some cases, the condition
cannot be cleared and the unit will require service. In those cases, an“Fx” failure mode will be displayed on the digital display. For a detailed
list of all error codes and “Fx” conditions, see section M.2, 6-Status LED Indicator Definitions for further details.
Memory–Your Premium unit also has memory. If power is lost, all of the control settings (set point, mode, fan speed, on/off and
configuration) are remembered. So when power is restored, the unit will start back up in the mode (and configuration) it was in, when power
was lost.
Premium Sound-The unit has 2 fan motors. The outdoor fan motor will run at minimum speed for 10 seconds before the compressor
start to reduce any compressor starting noise.
Random Compressor Restart-To help prevent power surges after a power outage (from many of your PTACS starting at the same
time), the compressor is equipped with a 2:45 to 3:15 random restart delay feature. Whenever the unit is plugged in, or power has been
restarted, a random compressor restart will occur.
Compressor Protection-To prevent short cycling of the compressor and maximize it’s life, there is a random start-up delay of 3
minutes on the compressor and a minimum compressor run time of 3 minutes.

A. IMPORTANT SAFETY AND GENERAL INFORMATION
Automatic Room Freeze Protection–automatically keeps the temperature in the room from getting too cold, where water pipes might
freeze. If the unit is configured for the freeze protection feature to be active (which is the default condition), then whenever power is supplied to
the unit, and the unit senses the temperature is below 40°F, the fan motor and electric heater are turned on, and will warm the room to 50°F.If
Freeze protection is not required, change the configuration switch to turn the feature off (see section J.3 Dip switches on unit configuration).
Automatic defrost protection –When the outdoor temperature gets too cold (approx. 28°F) and the unit can no longer effectively
heat with the compressor, the unit will automatically switch to electric heating. The unit will then heat with electric heat until the outside
temperature rises enough (approx.40°F), so the compressor can be used again.
Automatic Quick Warmup (for heat pump models only)-If the room temperature falls to 5°F below the set point temperature, the
reverse cycle heat is shut off and the electric strip heat is turned on for one cycle, until heating is satisfied.
LED Indicator’s and Buttons The touch pad has buttons for POWER, UP, DOWN, COOL, HEAT, CONSTANT FAN, HIGH, LOW and AUTO.
It also has LEDs that correspond to the mode, fan speed and set point operation, to indicate the unit’s status. The LEDs above the CONSTANT
FAN, COOL, and HEAT mode buttons indicate what operating mode is active. The LEDs above the LOW, AUTO, and HIGH buttons indicate the fan
speed that is selected. The LED above the power button is the unit On/Off status LED. If the unit is in ON mode, the LED will be blue. If the unit is
OFF, the LED will go out.
Configure Fan to Optimize Selected Application Unit can be optimized to selected application by configuring the fan to run in
continuous mode or cycle on and off with the compressor and electric heater. In cycle mode, fan will continue to run for a while after
compressor or electric heater stops in order blow off any residual heat or cool left on coil.
Unit Configuration There are many different configuration possibilities, through both dip switches and the digital keypad, that allow
you to configure the unit for your exact application. See section J.3 on unit configuration for more details. Following are the configuration
selections that have not previously been mentioned:
Temperature Display The unit can display in either °For °C
Indoor Temperature Sensor Biasing Optimize the room temperature sensor reading to your exact application (one for cooling and an
other for heating).
Emergency Heat (for Heat Pump Only) Disable the compressor during heating mode operation (heat only with Electric Heat).
Display Set point or Room Temperature The unit can be configured to display the room temperature or set point only, during heating
and cooling modes. See section J.3 on unit configuration for more details.
Limit the Set point Range The unit can be configured to limit the controlling set point range. The display will always show the
complete set point range, but the controlling set point will be limited to the configured minimum and maximum set point selected. See section
J.3 on unit configuration for more details.
Energy Management (Sometimes known as Front Desk Control) an input is provided so that the unit can be manually disabled from a
different location. If the unit detects 24vac on this input, it will automatically turn itself off. If no voltage is detected on the input, the unit will run
normally.
Wall Thermostat Control A wired wall thermostat can be connected to the unit. If it is, the unit must be configured to disable the
keypad. See section J.3 on wired inputs and unit configuration for more details.

E.3 Electrical Wiring
E.3.1 Power Cord Installation
All 265V PTAC units come with a factory installed non-LCDI power
cord for use in a sub-base. If the unit is to be hard-wired refer to the
instructions below.
NOTE: It is recommended that the PXSB sub-base assembly, the
PXCJA conduit kit (or equivalent) be installed on all hardwired units.
If installing a flush-floor mounted unit, make sure the chassis can be
removed from the sleeve for service and maintenance.
POWER CONNECTION OPTIONS
Appropriate power cord accessory kit is determined by the voltage,
and amperage of the branch circuit. If the unit is to be hard wired, an
accessory hard wire kit must be ordered.
IMPORTANT: For 265V units, if power cord accessory option is
selected, the cord is only 18” long and must plug into the accessory
electrical 265V sub-base. Be sure that your outlet matches the
appropriate blade configuration of the plug and that it is within reach
of the service cord. All wiring, including installation of the receptacle,
must be in accordance with the NEC and local codes, ordinances and
regulations. National codes require the use of an arc fault or leakage
current detection device on all 208/230V power cords. Be sure to
select the correct cord for your installation.
Wire Size
Install a single branch circuit. All wiring must comply with local
and national codes. All units are designed to operate off ONE single
branch circuits only.
NOTE: Use copper conductors only. Prepare the 265V (or 230V)
power cord for connection to the chassis’ power cord connector by
cutting the cord to the appropriate length.
Grounding
For safety and protection, the unit is grounded through the service cord plug
or through separate ground wire provided on hard wired units. Be sure that
the branch circuit or general purpose outlet is grounded.
VOLTAGE SUPPLY
Check voltage supply at outlet. For satisfactory results, the voltage range
must always be within the ranges found on the data information plate.
Cord-connected Units
The 250V- field supplied outlet must match the plug for the standard
208/230V- units and be within reach of the service cord. The standard cord-
connected 265V- units require an accessory electrical sub-base for operation.
Refer to Table E.1.1 for proper receptacle and fuse type.
Power Cord Protection
The power cord for 230/208V units provide power cord fire protection. Unit
power automatically disconnects when unsafe conditions are detected. Power
to the unit can be restored by pressing the reset button on plug head.
Upon completion of unit installation for 230/208V models, an operational
check should be performed using the TEST/RESET buttons on the plug head.
NOTE: The 265V models do not incorporate this feature as they require use of
the electrical sub-base accessory or are hard wired. To install the line voltage
power leads and conduit to chassis, follow the instructions on the next page
and refer to figure E.3.2.
WARNING
Electrical Shock Hazard
Make sure your electrical receptacle has the
same configuration as your air conditioner’s
plug. If different, consult a Licensed Electrician.
Do not use plug adapters.
Do not use an extension cord.
Do not remove ground prong.
Always plug into a grounded 3 prong outlet.
Failure to follow these instructions can result in

M. TROUBLESHOOTING
M.1. Troubleshooting Tips
SYMPTOM POSSIBLE CAUSES SOLUTIONS
UNIT DOES NOT START • Unit may have become unplugged
• Fuse may have blown
• Circuit breaker may have been tripped
• Unit may be off or in wall thermostat mode.
• Check section on dip switch settings to verify dip
switches are set properly.
• Unit may be in a protection or diagnostic failure mode.
See section on Intelligent Self- checking Control.
• Check that plug is plugged securely in wall receptacle.
• Note : Plug has a test/reset button on it. Make sure that
the plug has not tripped.
• Replace the fuse. See Note 1.
• Reset circuit breaker. See Note 1.
• Turn unit on (bottom right button on keypad).
• Note: If the unit turns on, the LED will be green. If the
unit is off, the LED will be red. If there is no LED on,
there is a problem with power or damage to the control.
UNIT NOT COOLING/
HEATING ROOM
• Unit air discharge section is blocked
• Temperature setting is not high or low enough Note:
Set-point limits may not allow the unit to heat or cool
the room to the temperature desired.
• Check section on dip switch settings.
• Unit air filters are dirty.
• Room is excessively hot or cold when unit is started.
• Vent door left open
• Unit may be in a protection or diagnostic failure mode.
Check section on Intelligent Self---checking Control.
• Compressor is in time delay. There is a protective time
delay (approx. 3 minutes) on starting the compressor
after a power outage (or restarting after it has been
turned off), to prevent tripping of the compressor
overload.
• Make sure that curtains, blinds or furniture are not
restricting or blocking unit airflow.
• Reset to a lower or higher temperature setting.
• 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.
• Close vent door.
• Check dip switch settings for desired comfort.
• Wait approximately 3 minutes for compressor to start
DISPLAY HAS STRANGE
NUMBERS/CHARACTERS
ON IT
• The unit may be in a diagnostic condition.
• The unit may be set for C (instead of F).
• Check Intelligent Self - checking Control section to
determine if unit has had a failure.
• See the keypad configuration section.
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 drain 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.
ICE OR FROST FORMS ON
INDOOR COIL
• Low outdoor temperature
• Dirty filters
• 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.
COMPRESSOR
PROTECTION
• Power may have cycled, so compressor is in a restart
protection.
• Random Compressor restart - Whenever the unit is
plugged in, or power has been restarted, a random
compressor restart will occur. After a power outage, the
compressor will restart after approximately 3 minutes.
• Compress or 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.
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

R . INFORMATION FOR THE OWNER
R.2 Routine Maintenance
Preventative maintenance is essential to proper unit operation,
efficiency and longevity. To ensure equipment operates properly,it
must be properly maintained. Equipment operation should be checked
and verified several times during each year. During regular unit
inspection and maintenance, follow the guidelines below:
Clean basepan and outdoor vent filter.
Clean or install new indoor-air inlet filter(s).
Clean wall sleeve and outdoor grille.
Inspect cord and receptacle.
Clean outdoor orifice and fan.
Clean indoor coil.(Never use high pressure spray on coils.)
Clean indoor fan,wire screen and front panel.
Secure electrical connections.
Ensure front panel is properly mounted and not damaged.
Ensure wall sleeve is installed properly.
Ensure heat and cool cycles operate properly.
Front panel and case
Turn unit off and disconnect power supply.
To clean, use water and a mild detergent. Do not use bleach or
abrasives. 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 or soot, coil should be
professionally cleaned.
Note: never use a high-pressure spray on coil.
Clean inside and outside of outdoor coils regularly.
R.3 Qualification Of Workers
Qualification of the working personnel for maintenance, service
and repair operations should according to UL 60335-2-40、CAN/
CSA-C22.2 No. 60335-2 -40-19 Annex HH.. Every working procedure
that affects safety means shall only be carried out by competent
persons according to Annex HH. Special training additional to
usual refrigerating equipment repair procedures is required when
equipment with FLAMMABLE REFRIGERANTS is affected.
Coils
Grill
Figure R.2.1 (Outdoor Coil)
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 filters 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.
The most important thing you can do to maintain unit efficiency is to clean
the filters at least every 30 days (or sooner depending on application).
Clogged filters reduce cooling, heating and airflow.
Keeping filters clean will:
Decrease cost of operation.
Save energy. Prevent clogged indoor coil.
Reduce risk of premature component failure.
To Clean Air Filters:
Vacuum off heavy soil.
Run water through filters.
Dry thoroughly before replacing.
Dirty Filter - Needs Cleaning Clogged Filter - Greatly Reduces
