Installation

For installation of the indoor unit(s), refer to the indoor unit

installation manual.
 Illustrations show RZQG125L outdoor unit type. Other types
also follow this installation manual.
 This outdoor unit requires the pipe branching kit (optional) when
used as the outdoor unit for the simultaneous operation system.
Refer to catalogues for details.
Never operate the unit with a damaged or disconnected

discharge thermistor and suction thermistor, 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.
3.5. Model identification
RZQG units include special equipment (insulation, optional bottom
plate heater, ...) to ensure good operation in areas where low ambient
temperature can occur together with high humidity conditions. In such
conditions the RZQSG models may experience problems with severe
ice build up on the air-cooled coil. If such conditions are expected, a
RZQG unit must be installed instead. These models contain
countermeasures (insulation, optional bottom plate heater, ...) to
prevent freeze up.

NOTICE
This is a class A product. In a domestic environment this
product may cause radio interference in which case the
user may be required to take adequate measures.
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 in heating operation.
- 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.
