Before Installation; Precautions For R410A; Accessories - Rotex RRHQ011AAV3 Manuel D'installation

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 drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation. See combination table in "Possible options" on
page 3.
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.
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.

EFORE INSTALLATION
Since maximum working pressure is 4.0 MPa or 40 bar,
pipes of larger wall thickness may be required. Refer to
paragraph "Selection of piping material" on page 5.

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 5 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 RKHBH/X016 unit
designed exclusively for R410A.
Installation
For installation of the indoor unit, refer to the indoor unit
installation manual.
Never operate the unit without the thermistor (R3T, R4T),
burning of the compressor may result.
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.
Model
RRHQ_W18 + RRHQ_V38 units include special equipment
(insulation, heater sheet,...) to ensure good operation in areas where
low ambient temperature can occur together with high humidity
conditions. In such conditions the RRHQ_V3 model may experience
problems with severe ice build up on the aircooled coil. In case such
conditions are expected, the RRHQ_V38 must be installed instead.
These models contain countermeasures (insulation, heater sheet,...)
to prevent freeze up.
