INTRODUCTION
THANK YOU FOR CHOOSING GREE CANADA!
GREE systems are among the most environmentally friendly and energy e󰀩cient in the market today.
You can feel condent in your selection because the same pride in craftsmanship and engineering
knowledge that goes into millions of other GREE installed products worldwide has gone into your unit.
COMFORT AND WELLNESS, IT’S WHAT WE DO
In 1991, GREE set out to make the world a cooler place. To this end, we’ve become a global leader in
air conditioners, developing some of the most advanced commercial and residential air conditioners in
the world. Based in Zhuhai, China, we’re now the world’s largest specialized air conditioner company
integrating R&D, manufacturing, sales and service. It’s our mission to innovate and create new ways to
help people live well and stay comfortable no matter where they live, work or play.
INNOVATION IS IN OUR DNA
Part of our responsibility is being mindful of the world we live in, which means we’re committed to using
innovation to design more eco-friendly air conditioners. Every year we commit 3% of our budget to
R&D. And, as a pioneer in the air conditioning industry, our R410A Refrigerant is eco-friendly.
LEADING THE WAY
From our humble beginning in 1991, GREE has grown over 80,000 strong across the world. With 3
research institutes, 9 product development centers, over 300+ labs and 5000+ engineers, we’ve abso-
lutely committed to nding newer and more e󰀩cient ways to keep our customers comfortable, healthy
and productive.
A GLOBAL CITIZEN OF THE WORLD
Today, we’ve developed some of the world’s most energy-e󰀩cient and technically advanced air con-
ditioners. From the 2008 Beijing Olympic Games Media Village to the main stadium of the 2010 Africa
World Cup, GREE is trusted to help people stay comfortable in the most extreme environments. Res-
identially, we’ve created wonders of technology that are just as contemporary, beautiful and e󰀩cient.

ENERGY SAVING TIPS
1. CLEAN OR REPLACE INDOOR RETURN AIR FILTER
A clean return air lter will allow for proper airow and will ensure that your system is running at its
optimum performance and e󰀩ciency. Check your air lter every 30 days during cooling and heating
seasons, and clean or replace it if its dirty.
2. INSTALL A PROGRAMMABLE, WI-FI, SMART THERMOSTAT
A programmable Wi-Fi smart thermostat will allow you to monitor and control your homes cooling and
heating temperature settings from a smart phone, tablet, or computer whenever you are away. They are
designed to provide comfort and energy savings by using algorithms and operating history to adjust the
operating settings throughout the day.
3. ADJUST THERMOSTAT SETTINGS
Programming an occupied & unoccupied schedule throughout the week will not only save energy, it will
also reduce the wear and prolong the lifespan of your equipment by preventing the system from oper-
ating when it is not necessary.
4. ROOMS EXPOSED TO DIRECT SUNLIGHT
In the cooling season it is recommended to block the radiant heat e󰀨ect from the sun by closing all
window coverings during the daytime.
In the heating season it is recommended to open all window covers to allow for the radiant heat from
the sun to help warm the spaces being conditioned.
5. ROUTINE MAINTENANCE & SERVICE
Keeping the area around the outdoor unit clear from any debris or leaves will allow for your system to
run at its optimum performance and e󰀩ciency in both cooling and heating seasons.
In heating mode, be sure to clear the underside of the unit of any snow or ice that may accumulate fol-
lowing defrost cycles. It is critical to the proper operation of the heat pump that the outdoor unit is never
buried, even partially, by ice or snow.
A heat pump shelter protecting the outdoor unit from excessive snow accumulation is sometimes re-
quired in certain situations where the weather is more frequent and regular. Consult your GREE Cana-
da-certied installer for more information on shelters that can be installed.
Scheduling a pre-season routine maintenance to be performed by a licensed HVAC contractor can
improve the systems

PROBLEM POSSIBLE CAUSES POSSIBLE SOLUTIONS
The unit does
not appear to be
operating.
The unit is disconnected from
the power supply.
Verify that the unit is connected to
the power supply.
There may have been a power
outage.
If there is a power outage and the
electricity is not yet restored, wait
for the power to be restored. When
it is, the unit may need to be re-
started.
The voltage is too low. Verify that the circuit voltage is
within the rated value.
A circuit breaker may have
been tripped or a fuse may
have blown.
Replace the fuse or reset the cir-
cuit breaker. Make sure that there
are no other appliances on the
same circuit.
The e󰀩ciency of the
cooling or heating is
very poor.
The air inlets or outlets of the
indoor or outdoor unit may be
obstructed.
Clear away any objects or furniture
that could be blocking the air inlet
or outlet of either units.
The set temperature may not be
suitable for the current outdoor
conditions.
Set the temperature to be higher or
lower, depending in the conditions.
Doors or windows may have
been left open in the room.
Close doors and windows to pre-
vent cooled or heated air from
escaping the room.
Direct sunlight may be warming
the room.
Draw the curtain or close the blind
to minimize the e󰀨ect of the sun.
There may be heat sources
present when attempting to cool
the room.
Turn o󰀨 or remove any heat
sources that could be counteract-
ing the cooling e󰀩ciency of the
unit.
