Installation Of The Unit; Selecting Installation Location - Rotex RRRQ011AAV1 Manuel D'installation

Caution
■
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
of the indoor unit" or when in "thermostat-stop" operation.
■
Live parts can be easily touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.
■
Earth the unit.
Earth 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 grounding 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 "General information"
on page 1.
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.
■
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.
■
Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.

NSTALLATION OF THE UNIT

4.1. Selecting installation location

■
Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.
■
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
1 Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
- Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.
- Places where there is no possibility of flammable gas or
product leak.
- The equipment is not intended for use in a potentially
explosive atmosphere.
- Places where servicing space can be well ensured.
- Places where the indoor and outdoor units' piping and wiring
lengths come within the allowable ranges.
- Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).
- Places where the rain can be avoided as much as possible.
2 When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:
- Deterioration of the operational capacity.
- Frequent frost acceleration.
- Disruption of operation due to rise of high pressure.
- When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.
■
Install a baffle plate on the air suction side of the outdoor unit
and set the outlet side at a right angle to the direction of the
wind:
