Before Installation; Important Information Regarding The Refrigerant Used - Daikin EWAQ-ACV3 Installation Manual

Caution
Earth the unit.
Earthing resistance should be according to national regulations
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete earthing may cause electric shocks.
Gas pipe.
Ignition or explosion may occur if the gas leaks.
Water pipe.
Hard vinyl tubes are not effective earths.
Lightning conductor or telephone earth wire.
Electric potential may rise abnormally if struck by a lightning
bolt.
Be sure to install an earth leakage circuit breaker.
Failure to install an earth leakage circuit breaker may cause
electric shocks and fire.
Install the power 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 unit. This may cause electric shocks or fire.
Do not install the unit in places such as the following:
Where there is mist of mineral oil, oil spray or vapour.
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.

EFORE INSTALLATION
Installation
Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.
When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.
In case ambient temperatures below 0°C are expected,
countermeasures need to be taken to prevent the water in the
unit from freezing. In such cases, we recommend to install the
heater tape option OP10 or we advise to put glycol in the
system. See "Protecting the water circuit against freezing" on
page 10. It is also allowed to drain the water from the system
when longer periods of standstill are expected.
Model
EWAQ and EWYQ units include optional special equipment
(insulation, heater tape,...) to ensure good operation in areas where
low ambient temperature can occur together with high humidity
conditions. In such conditions the units may experience problems
with severe ice build up on the aircooled coil. In case such conditions
are expected, the heater tape option OP10 must be installed instead.
Possible options
Model OP10

EWA/YQ_AC*H-H- Factory mounted
(a) Heater tape option OP10
(b) High ESP pump
Handling
Due to relatively large dimensions
and high weight, the handling of the
unit is only to be done by means of
lifting tools with slings. These slings
can be fitted into specially for this
purpose foreseen sleeves at the
base frame.
To avoid injury, do not
touch the air inlet or
aluminium fins of the
unit.
Do not use the grips
in the fan grills to
avoid damage.
