▪ Sound sensitive areas (e.g. near a bedroom), so that the
operation noise will cause no trouble.
Note: If the sound is measured under actual installation
conditions, the measured value might be higher than the sound
pressure level mentioned in Sound spectrum in the data book due
to environmental noise and sound reflections.
INFORMATION
The sound pressure level is less than 70 dBA.
▪ In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
It is NOT recommended to install the unit in the following places
because it may shorten the life of the unit:
▪ Where the voltage fluctuates a lot
▪ In vehicles or vessels
▪ Where acidic or alkaline vapour is present
Seaside installation. Make sure the outdoor unit is NOT directly
exposed to sea winds. This is to prevent corrosion caused by high
levels of salt in the air, which might shorten the life of the unit.
Install the outdoor unit away from direct sea winds.
Example: Behind the building.

If the outdoor unit is exposed to direct sea winds, install a
windbreaker.
▪ Height of windbreaker≥1.5×height of outdoor unit
▪ Mind the service space requirements when installing the
windbreaker.

Strong winds (≥18 km/h) blowing against the outdoor unit’s air outlet
causes short circuit (suction of discharge air). This may result in:
▪ deterioration of the operational capacity;
▪ frequent frost acceleration in heating operation;
▪ disruption of operation due to decrease of low pressure or
increase of high pressure;
▪ a broken fan (if a strong wind blows continuously on the fan, it
may start rotating very fast, until it breaks).
It is recommended to install a baffle plate when the air outlet is
exposed to wind.
It is recommended to install the outdoor unit with the air inlet facing
the wall and NOT directly exposed to the wind.

The outdoor unit is designed for outdoor installation only, and for
ambient temperatures ranging:
Model Cooling Heating
RZQG –15~50°C –20~15.5°C
RZQSG –15~46°C –15~15.5°C
5.2.2 Additional installation site requirements
of the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.
