CUSTOMER AND TECHNICIAN MUST READ
CUSTOMER AND TECHNICIAN MUST READ
Dear Customer(s)/End User(s)/Unit Purchaser(s)/Installer(s)/Contractor(s)
Thanks for choosing YMGI products.
Reading and following the YMGI Group recommendations, suggestions, and requirements, written in the
following pages and other documents, is the first step in our hope and effort to help ensure a smooth installation
& proper operation of your products for many years.
WHY DOES YMGI GROUP REQUIRE INSTALLATION AND SERVICE TO BE
PERFORMED BY LICENSED OR CERTIFIED HVAC TECHNICIAN/
CONTRACTOR?
1) They have the training and experience to accurately and safely install and service your equipment.
The equipment runs with high-pressure refrigerant and oil and line-voltage. The copper lines must be installed
properly to prevent leakage and foreign substances from contaminating the refrigerant system.
2) You will save money in the long run.
If any problems occur on the unit that is fully installed by the licensed or certified contractor, they have the
training and experience to correct the problem more efficiently. A technician(s) may be unwilling to repair an
issue on a unit that they did not install. If you do find a technician willing to perform the service, there is an
increased possibility of higher service fees than normal, increased service visits, or delayed service from that
technician.
3) It's the law!
The federal, state and/or local government and authorities have various governing laws or regulations,
guidelines, ordinances, etc., requiring only licensed or certified professionals can install and service high
pressure HVAC equipment.
SUGGESTIONS, TO AID YOU IN HIRING AN HVAC CONTRACTOR:
The cost of not having your unit installed properly can be more expensive than spending the little extra money
that hiring the right contractor will cost. Protect your investment and warranty eligibility by doing it right the first
time.
THE FOLLOWING LISTS THE JOBS AND RESPONSIBILITIES OF THE
TECHNICIAN/ CONTRACTOR:
* Performing a load calculation for the room(s) you would like to air condition. Cooling requirements will be
different from the heating requirements. They will consider cooling hours, heating hours and your special needs
or requirements. Supplemental heating such as baseboard heater or portable heater may help you save money
by not over-sizing or under-sizing the heating equipment.
* Selecting the right type, size or model of cooling and/or heating equipment.
* Determining the best location to install the unit. (Positioning indoor unit, outdoor unit and running the interconnecting pipes/wires.)
* Selecting the correct electrical components (HVAC circuit breaker or fuse and disconnect switch for the electric
power to the outdoor unit, types and sizes of the connecting wires between circuit breaker/disconnect switch
and outdoor unit, and the wires between outdoor unit and indoor unit).
* Keeping the indoor unit away from the ceiling and the outdoor unit away from the wall, bushes and other
obstacles at a proper and safe distance to allow for the proper airflow through the unit's.
* Placing the units on a secured level structure.
* Taping and sealing both ends of the inter-connecting pipes, before running them through structures, to prevent
dust or other debris from getting into the pipes otherwise they will contaminate and damage the refrigeration
system. Failure to follow this practice will make your factory warranty void.
* Connecting the inter-connecting pipes between the outdoor and indoor units. Checking for leaks through
pressurization with nitrogen. After releasing nitrogen, evacuate the piping and indoor unit, for removal of system
contaminants. Finally refrigerant introduction and adjustment, if necessary, from the outdoor unit.
* Back-seating the stopping valves at outdoor condensing unit to release pre-charged refrigerant from outdoor
unit to indoor unit.
* Measuring and recording the electrical voltages at different terminals and the refrigerant pressures at stopping
valves of outdoor condensing unit.
* Verifying and ensuring the unit is connected to the proper electrical power supply.
* Adjusting refrigerant levels (if necessary) following the installation instructions or chart on the unit.
* Checking for any unusual noises and other abnormalities that might be present.
* Operating the unit and check all functions, one by one, and explain to the owner how to operate and maintain
the unit.
* Completing all fields in detail on the installer checklist, signing and dating the Warranty Registration Card/Form.
1) Hire a currently, practicing, licensed/ certified HVAC technician/ contractor. Technicians, who are no longer
practicing (retired, etc.) in this field, may not have the updated knowledge or may lack experience on the
equipment you have purchased.
2) Hire a technician/ contractor who services customers in your local area and you are familiar with. Local
contractors have a faster response time and will be easier for you to determine if they are reputable.
3) Use only reputable licensed/ certified HVAC installation contractors/ technicians to prevent any unexpected
charges as a result from unethical business practices.
4) Check their references, to verify they are a good service provider to the general customers. N.A.T.E or A.C.C.A
certified technicians are strongly recommended.
5) Some contractors/ technicians may not feel comfortable about installing the equipment that you purchase for
them to install, and they prefer to purchase and install the equipment. You can contact YMGI directly to check
and see if there have been any contractors in your area who have installed our products or similar.
6) Ask for a detailed quote for the whole installation project. A flat rate quote is the safest contract for both you
and the contractor
7) Your local HVAC technicians may charge you on a project basis or on an hourly basis. To our general
knowledge and experience, a full single head installation may normally cost anywhere from $800 to
$1500. These costs are estimates and your actual costs may differ due to job nature and location.
8) Number of hours can vary depending upon each individual situation, some factors are, but not limited to:
9) How difficult or complex the indoor unit is to be securely installed.
10) Hoe difficult or how long the inter-connecting pipes and wires are to be installed.
11) If all the suggestions have been taken and all the necessary steps are followed.
If the installation is successfully and fully done by a qualified licensed/ certified HVAC technician/contractor, the
registration card/form is filled completely and correctly, and filed along with a valid installation invoice from the
contractor company within 7 days of the original installation, the following standard Limited Product Warranty is
qualified:
5-year on compressor and 1-year other PARTS ONLY. There is no labor coverage.

The YMGI equipment you purchased is either a split-type or a self-contained cooling/heating system which
requires an installer's license, certification, knowledge, experience, carefulness and details for a successful and
good installation. This equipment is different from those window or portable air conditioners you can normally
purchase from local retail stores such as Home Depot, Lowe's, Sears, etc. which the manufacturer may not
require licensed personnel to install.
12) If the contractor(s)/technician(s) are experienced with the systems/brands you purchase.
You might spend less. But remember, many times you get what you pay for.
13) Sign a contract with them. The contract should list all the detailed work they will conduct and the standards
they will follow. Some contractors are willing to include a 1-year installation/service warranty at no extra
charge. Check with them to see if that is available. If available, include that in the contract.
14) Verify and confirm the installation is done completely and all the unit functions have been checked and are
working properly, all the items in the checklist have been checked and marked well in the warranty registration
card/form, prior to paying the contractor in full.

Following these requirements will aid in ensuring the units will be installed to the general HVAC practicing
standards and are necessary factory requirements, to find problems early, prevent possible damage to the unit
and help ensure the unit will work properly for its life time.
QUESTIONS ABOUT SELF-INSTALLATION VS HIRING LICENSED HVAC
TECHNICIANS
Does YMGI allow to do-it-yourself installations (DIY) partially or fully? NO.
Unfortunately no brand or manufacturer can take the responsibility of the equipment if it is not professionally
installed by a currently licensed HVAC technician/ contractor.
If unit is installed by non-licensed people, in part or fully, will the factory warranty be void? YES.
Some DIY installations have been successful, but these are exceptions. Most have resulted in equipment failure,
due to lack of knowledge and experience. A few of the problems result from DIY's lack of knowledge in the
following areas:
* Sizing and selecting correct type, size and model of cooling and/or heating equipment.
* Sizing and installing correct electric circuit breakers and wires.
* Wiring the units correctly and properly.
* Taping the ends, connecting to indoor and outdoor units correctly and properly.
* Vacuuming the inter-connecting refrigerant lines.
* Checking and/or fixing the refrigerant leaks.
* Checking and/or fixing the condensate drain leaks.
* Releasing the refrigerant from outdoor unit to indoor unit.
* Running the unit to check all the unit functions.
* Conducting the installation or trouble-shooting with correct tools, experience or professional knowledge to
correct the problem.

DEFECTIVE UNITS / PARTS / ACCESSORIES-REPAIR OR REPLACEMENT
Out of thousands of units sold every year, there may be an occasional instance your product does not operate
properly. Reasons of but are not limited to: manufacturing, installation, operation, maintenance and
knowledge of operator.
Equipment failure does not automatically denote a product defect from the factory assembly line. The defects can
be caused, during production, transportation, installation, operation, maintenance, or service. Defects may NOT
be the responsibility of the manufacturer. Nobody willfully or intentionally produces a defective product. No
determination shall be made until the technical issue(s) or the causes of the defect(s) are identified.
The defects might be found before/ during installation or in the operation of the unit. Defects can be in the form
of blown fuse(s), defective control board(s), damaged remote control, loose or missing screws, etc. These
defective parts can be replaced easily.
Some functions of our units are different from what are typical in traditional split type air conditioning and heat
pump systems and similar systems made by other manufacturers. These are not defects. Take some time to
learn the functions of your unit. We will be happy to assist you with any questions you may have concerning the
functions of your new unit.
If a defect is found, whether at the original installation, or during normal operation, we will gladly help you in the
following steps in sequence from 1 to 3:
1. Part repair or replacement after trouble-shooting: This is the most common and generally the easiest and
most economical way for all parties, since the problem and all part needs can be accurately and completely
identified.
* Your technician calls our technical support line, from your job site, after checking your units and getting all the information
ready.
* Our technical support will go through several steps, over the phone or through email, with your technician, in order to help
identify and resolve the problems. Normally wiring correction, piping correction, part repair/ replacement will resolve the
problems.

P9 OF 36
* Your technician will then need to verify and confirm the problem(s) before YMGI can ship out the replacement part(s).
Inaccurate or incomplete troubleshooting or part replacement will delay the repair. YMGI technical support will only speak
with a licensed/certified technician in regards to the repair of your unit. In our experience this saves time and money for
all parties involved.
Your technician is the only person to perform any physical checking, trouble-shooting and replacing of any
defective part(s) for your units. Our factory technical support is just a help. YMGI provided no labor warranty
on the products.
2. Unit/part repair at our workshop(s): Due to the limitations of our technical support not being at your job site,
or your technician's experience with our product, the problem may not be resolved as quickly as would be
desired. If the problem is still not resolved after attempts between your technician and our technical support,
you can elect to have the unit repaired at our facility. If this step is chosen:
1) YMGI will send to you the Customer Request to Ship Products to YMGI Service Center for Inspection and Repair,
and Authorization to Charge form.
2) You will review the form and fill all fields appropriately, sign and send back to the YMGI Group.
3) Once the form has been completed and sent back to YMGI, remove the units and ship back to YMGI.
Please make a note describing the problem and communication history, if possible. Our technicians will check the
units and find the problem(s), repair the issue(s), and ship the unit back to you following the conditions set forth in
the signed repair agreement. All unit removal and re-installation is done at your cost and must be done by a
currently valid licensed HVAC technician.
3. Unit replacement: Only applies to those defects reported within 30 days of original purchase date and if all
necessary warranty paperwork had been received and approved. This option applies only if the above steps
cannot resolve the problem(s). Either indoor or outdoor unit replacement is available, based on the actual need,
at YMGI's determination. This option shall be the last resort, due to refrigerant and wiring considerations. All
unit removal, re-installation and shipping cost are the responsibility of the customer. YMGI maintains the final
authority as to unit replacement. Replacement will be made with the same model only. Alternate units will be
treated as a new order.
Returning Replaced Defective Units/Parts/Accessories After Unit Repair: (Only applies to steps 1&3 above)
1) Repack the replaced unit/ part /accessory in the box which contained the replacement part.
2) Parts can be boxed for UPS, FedEx or equivalent ground service. Units shall be secured onto the skid on which the
replacement was shipped after placing into the package from the replacement product.
3) Ship all replaced products, to YMGI-designated location. You will be charged if YMGI does not receive the replaced parts.
Standard factory warranty does not cover the cost of materials and labor that are incurred at your site.
There will be no cost for the replacement unit, if YMGI determines the defect is manufacturer related.
Replacement will be made with the same model, only. Alternate units will be treated as a new order.

UNIT FEATURES
UNIT SPECIFICATIONS
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.

* 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 spell will start back up in
the mode (and configuration) it was in, when power was lost.
* Premium Sound - Not only does The unit have 2 fan motors and a tangential blower wheel for optimum sound,
the indoor fan will always run a minimum of 10 seconds before the compressor, to help reduce any compressor
starting noise.
* Random Compressor restart - To help prevent power surges after a power outage (from many of your PTAC
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.
* Automatic room freeze protection - automatically will keep 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, if the unit senses temperature below 40OF,
the fan motor and electric heater are turned on and will warm the room to 50OF. If Freeze protection is not
required, change the configuration switch to turn the feature off (see section on unit configuration).
* Automatic defrost protection (for heat pump models only) - When the outdoor temperature gets too cold
(approx. 35OF) 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. 40OF), so the compressor can be used again.
* Automatic Quick Warm-up (for heat pump models only) - If the room temperature falls to 5OF 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 MODE, FANSPEED, ON/OFF, SETPOINT UP
and SETPOINT DOWN. It also has LEDs that correspond to the mode, fan speed and setpoint operation, to
indicate the unit's status. The LEDs below the mode button, FAN, COOL, and HEAT, indicate what operating
mode is active. The LEDs below the Fan button, Low, Med and Hi, indicate the fan speed that is selected. The
LED located in the lower right corner is the unit On/Off status LED. If the unit is in ON mode, the LED will be
green. If the unit is OFF, the LED will be red.
* 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 (can
be different for both heating and cooling modes). In cycle mode, fan will continue to run after compressor or
electric heater stops in order blow off any residual heat or cool left on coil.

BRIEF UNIT INFO
BRIEF UNIT INFO
* 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 Table 6 - Status LED Indicator Definitions for further details.

UNIT FEATURES CONTINUED
ELECTRICAL DATA
* Unit Configuration - There are many different configuration possibilities, through both dips witches and the
digital keypad, that allow you to configure the unit for your exact application. See section on unit configuration
for more details. Following are the configuration selections that have-not previously been mentioned:
VOLTAGE SUPPLY
* OF or OC - The unit can display in either OF or OC. Spell out (Fahrenheit) or (Celsius).
Cord-connected Units
* Indoor Temperature Sensor Biasing - Optimize the room temperature sensor reading to your exact
application (one for cooling and another for heating)..
The 250-v field supplied outlet must match the plug for the standard 208/230--v units and be within reach of the
service cord. The standard cord-connected 265-v units require an accessory electrical subbase for operation.
Refer to Table 2 for proper receptacle and fuse type.
* 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 on unit configuration for more details.
BRIEF UNIT INFO
* 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 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 on wired inputs and unit configuration for more details.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death and/or property damage DO NOT alter cord
or plug or use an extension cord.
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 subbase accessory.

Appropriate power cord accessory kit is determined by the voltage, and amperage of the branch circuit.
The unit does not come with a power cord (or hard wire kit). An accessory power cord kit must be ordered to
connect the unit to the outlet. 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 subbase.
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.
ALL UNITS
Wire Size
Use recommended wire size given in Table 1 and 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.

Proper installation is the responsibility of the installer.
Product failure due to improper installation is not covered under the Warranty.
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended that a YMGI
or Carrier sleeve be used.
These units can retrofit General Electric, Amana, Trane, and Friedrich sleeves/grilles (be sure outdoor
grille is installed on the sleeve). See Table 3 for details.
For any sleeve retrofit applications, be sure that the foam seals (factory--installed on the tube sheets) provide a
good seal between the grille and outdoor coil tube sheets. These foam seals provide a barrier to separate
outdoor coil leaving air from mixing with the outdoor incoming air (known as air reticulation).

prevent fresh air vent door from opening and may
result in damage to vent door cable.
GE Sleeves Only
GE Meta l Wall Sleeve - GE metal sleeve is interchangeable with YMGI wall sleeve.
GE Plastic Sleeve - Remove bottom seal from plastic sleeve.
INSTALLATION OF A YMGI OR CARRIER WALL SLEEVE USING A NON-YMGI GRILLE
This application has become more common due to pre - manufactured windows with built--in grilles or
renovations where a YMGI or Carrier sleeve is used with an existing non - YMGI grille.
Use of a YMGI or Carrier wall sleeve with a non - YMGI grille requires installation of an Accessory Baffle Kit,
which ensures a good seal between the unit and exterior grille to prevent air reticulation. Air reticulation
is a large contributor to performance loss and premature damage to major components.
Notes: YMGI stamped grille is interchangeable with CARRIER'S.

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.
* Reduce risk of premature component failure.
TIMER
To Clean Air Filters:
* Vacuum off heavy soil.
Removing Air Filter
* Run water through filters.
* Dry thoroughly before replacing.
ON/OFF
Dirty filterNeeds cleaning
Clogged filter Greatly reduces cooling,
heating and airflow.
Identifying Clogged Filter
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.
Coils
BASE PAN
Grille
In some installations, dirt or other debris may be
blown into unit from outside and settle in base pan
(bottom of unit).
In some areas of the United States, a "jell-like"
substance may be seen in the base pan. Check base
pan periodically and clean, if necessary.
IMPORTANT: TURN UNIT OFF BEFORE CLEANING
