6 Preparation
NOTICE
This unit is designed for operation on 2 temperature zones:
▪ underfloor heating
temperature 35°C), this is the zone with the lowest
water temperature,
▪ radiators in the additional zone (water temperature
45°C), this is the zone with the highest water
temperature.
6.2.1 Installation site requirements of the
outdoor unit
INFORMATION
Also read the following requirements:
▪ General installation
"General safety precautions" chapter.
▪ Service space requirements. See the "Technical data"
chapter.
▪ Refrigerant piping
difference). See further in this "Preparation" chapter.
See "14.2 Dimensions and service space" on page 71
detailed information about spacing guidelines.
▪ Select a place where rain can be avoided as much as possible.
▪ Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.
Do NOT install the unit in the following places:
▪ Sound sensitive areas (e.g. near a bedroom and the like), 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.
▪ 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:
▪ in coastal areas or other places where the air contains high levels
of salt. Corrosion may occur,
▪ where the voltage fluctuates a lot,
▪ in vehicles or vessels,
▪ where acidic or alkaline vapour is present.
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.
