SAFETY INSTRUCTIONS
Read these “SAFETY INSTRUCTIONS for Installation” care-
fully before installing an air conditioner or heat pump. After
completing the installation, make sure that the unit operates
properly during the start-up operation.
Instruct the customer on how to operate and maintain the
unit. Inform customers that they should store this Installation
Manual with the Operation Manual for future reference.
Always use a licensed installer or contractor to install this
product. Improper installation can result in water or refriger-
ant leakage, electrical shock, fire, or explosion.
•
Refrigerant gas is heavier than air and replaces oxygen.
A massive leak can lead to oxygen depletion, especially
in basements, and an asphyxiation hazard could occur
leading to serious injury or death. For a refrigerant leak,
contact your licensed professional contractor.
•
Do not ground units to water pipes, gas pipes, telephone
wires or lightning rods since incomplete grounding can
cause a severe shock hazard, resulting in severe injury
or death. Additionally, grounding to gas pipes could
cause a gas leak resulting in a potential explosion caus-
ing severe injury or death.
•
If refrigerant gas leaks during installation, ventilate the
area immediately. Refrigerant gas may produce toxic gas
if it comes in contact with fire. Exposure to this gas could
cause severe injury or death.
•
After completing the installation work, ensure the re-
frigerant gas does not leak anywhere in the system.
•
Due to the risk of explosions that can cause serious
injury or death, do not install the unit in an area where
flammable materials are present.
•
Safely dispose of all packing and transportation materi-
als in accordance with federal/state/local laws or ordi-
nances. Plastic packing materials used for transporta-
tion may cause injuries or death by suffocation.
Nails and other metal or wood parts used for packing
may cause wounds or other injuries.
•
All phases of the field-installation, including, but not lim-
ited to, electrical, piping, safety, etc., must be in accor-
dance with manufacturer’s instructions and must com-
ply with national, state, provincial and local codes.
•
Only a licensed professional contractor should install
this equipment and must be done in accordance with
this installation manual. Improper installation could lead
to leaks and electric shock or fire.
•
When installing the unit in a small room, ensure the re-
frigerant concentration does not exceed allowable safety
limits. Excessive accidental refrigerant leaks in a closed
ambient space can lead to oxygen deficiency.
•
Do not use any device that is not design-certified by
Daikin for use with this unit. Serious property damage,
personal injury, reduced unit performance and/or haz-
ardous conditions may result from the use of such non-
approved devices.
•
Install the air conditioner or heat pump on a foundation
strong enough that it can withstand the weight of the
unit. A foundation of insufficient strength may result in
the unit falling and causing injuries.
•
When installing, take into account strong winds, ty-
phoons or earthquakes. Improper installation may re-
sult in the unit falling and injuries.
•
Make sure that a separate power supply circuit is pro-
vided for this unit and that all electrical work is carried
out by qualified personnel according to local, state, and
national regulations. An insufficient power supply ca-
pacity or improper electrical construction may lead to
electric shocks or fire.
•
Make sure that all wiring is secured, that specified wires
are used and that no external forces act on the terminal
connections or wires. Improper connections or instal-
lation may result in fire.
•
When wiring, position the wires so that the control panel
and cover can be securely fastened. Improper position-
ing of the control panel and cover may result in electric
shocks, fire or the terminals overheating.
If the control panel cover is not installed properly, dust
or water may enter the control panel causing fire or elec-
tric shock.
•
Before touching electrical parts, turn off the unit.
