1. SAFETY CONSIDERATIONS
Read these "SAFETY CONSIDERATIONS for Installation"
carefully before installing the ERV unit. After completing the
installation, make sure that the unit operates properly during a
test run.
Instruct the customer on how to operate and maintain the unit.
Inform the customer that this Installation Manual should be
kept with the Operation Manual for future reference.
Always use a licensed installer or contractor to install this prod-
uct. Improper installation can result in water or refrigerant leak-
age, electrical shock, fire or explosion.
Meanings of DANGER, WARNING, CAUTION and NOTE Sym-
bols:
DANGER.................Indicates an imminently hazardous
WARNING ...............Indicates a potentially hazardous situ-
CAUTION ................Indicates a potentially hazardous situ-
NOTE ......................Indicates situations that may result in
DANGER
• Do not ground units to water pipes, gas pipes, tele-
phone wires or lightning rods as incomplete grounding
can cause a severe shock hazard resulting in severe
injury or death. Additionally, grounding to gas pipes
could cause a gas leak and potential explosion causing
severe injury or death.
• Do not install unit in an area where flammable materials
are present due to risk of explosions that can cause
serious injury or death.
• Safely dispose all packing and transportation materials
in accordance with federal/state/local laws or ordi-
nances. Packing materials such as nails, other metal or
wood parts, including plastic packing materials used for
transportation may cause injuries or death by suffoca-
tion.

WARNING
• Only qualified personnel must carry out the installation
work. Installation must be done in accordance with this
installation manual. Improper installation may result in
water leakage, electric shock or fire.
• Use only specified accessories and parts for installa-
tion work. Failure to use specified parts may result in
water leakage, electric shocks, fire or the unit falling.
• Install the unit 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.
• Take into account strong winds, typhoons or earth-
quakes when installing. Improper installation may result
in the unit falling and causing accidents.
• 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
capacity 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 installa-
tion may result in fire.
• When wiring, position the wires so that the control box
cover can be securely fastened. Improper positioning of
the control box cover may result in electric shocks, fire
or the terminals overheating.
• Before touching electrical parts, turn off the unit.
• Be sure to install a ground fault circuit interrupter if one
is not already available. This helps prevent electrical
shocks or fire.
• Do not change the setting of the protection devices. If the
pressure switch, thermal switch or other protection device
is shorted and operated forcibly, or parts other than those
specified by Daikin are used, fire or explosion may occur.
• Locate the outdoor air intake vent so that it does not
take in exhaust air which contains combustion air, etc.
Incorrect installation may cause a loss of oxygen in the
room, leading to serious accidents.
• Install the two outdoor ducts with down slope to prevent
rainwater from entering the unit.
If this is not done completely, water may enter the building,
may damage furniture, and cause electric shocks and fire.
• Insulate the duct and the wall electrically when a metal
duct is to be penetrated through the metal lattice and
wire lattice or metal lining of a wooden structure wall.
Improper duct work may cause electric shocks or fire.
• Make sure the temperature and humidity near the unit
and the air suction/discharge air grille is within limit dic-
tated by the usage conditions.
1. Refrigerated truck or other locations with low tem-
peratures.
2. Place such as bathroom or heated pools subjected to
moisture.
This may cause fires or electric leak or electric shocks.
• Make sure that a snow protection measure is taken. If no
protection snow may enter through the outdoor ducts, and
cause damaging furniture and electric shock and fire.
