Before Installation - Daikin ERLQ036BAVJU Manual De Instalación

Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, overheat of the terminals,
electric shocks or a fire may be caused.
If refrigerant gas leaks during installation work, ventilate the
area immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.
Do not touch the refrigerant pipes during and immediately after
operation as the refrigerant pipes may be hot or cold, depending
on the condition of the refrigerant flowing through the refrigerant
piping, compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the refrigerant
pipes. To avoid injury, give the pipes time to return to normal
temperature or, if you must touch them, be sure to wear proper
gloves.
After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
When planning to relocate former installed units, you must first
recover the refrigerant after the pump down operation. Refer to
chapter "Pump down operation" on page 10.
Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
Be sure to install a ground fault circuit interrupter in accordance
with relevant local laws and regulations. Failure to do so may
cause electrical shock and fire.
Caution
Ground the unit.
Grounding resistance should be according to local laws and
regulations.
Do not connect the ground wire to gas or water pipes,
lightning conductor or telephone ground wire.
Incomplete grounding may cause electric shocks.
Gas pipe.
Ignition or explosion may occur if the gas leaks.
Water pipe.
Hard vinyl tubes are not effective grounds.
Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by a lightning
bolt.
Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and make the
furnitures get wet.
Install the indoor and outdoor units, power wire and connecting
wire at least 1 meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)
Do not rinse the outdoor unit. This may cause electric shocks or
fire.
Installation manual
2
Do not install the unit in places such as the following:
Where there is mist of mineral oil, oil spray or vapour for
example a kitchen.
Plastic parts may deteriorate, and cause them to fall out or
water to leak.
Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may cause the
refrigerant to leak.
Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system, and
cause malfunction of the equipment.
Where flammable gases may leak, where carbon fiber or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
Such gases may cause a fire.
Where the air contains high levels of salt such as that near
the ocean.
Where voltage fluctuates a lot, such as that in factories.
In vehicles or vessels.
Where acidic or alkaline vapour is present.
Do not allow a child to mount on the outdoor unit or avoid
placing any object on the unit. Falling or tumbling may result in
injury.
For use of units in applications with temperature alarm settings it
is advised to foresee a delay of 10 minutes for signalling the
alarm in case the alarm temperature is exceeded. The unit may
stop for several minutes during normal operation for "defrosting
the unit", or when in "thermosta-stop" operation.

EFORE INSTALLATION
Since maximum working pressure is 580 psi (4.0 MPa or
40 bar), pipes of larger wall thickness may be required.
Refer to paragraph "Selection of piping material" on
page 6.
Precautions for R410A
The refrigerant requires strict cautions for keeping the system
clean, dry and tight.
- Clean and dry
Foreign materials (including mineral oils or moisture) should
be prevented from getting mixed into the system.
- Tight
Read "Precautions on refrigerant piping" on page 6 carefully
and follow these procedures correctly.
Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant
is in state of gas, its composition changes and the system will
not work properly).
The connected indoor unit must be the EKHBH/X016 unit
designed exclusively for R410A.
