ELECTION OF 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.
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
If not, the unit may fall over and cause damage or
injury.
The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available. (Refer to
figure 1 and choose one of the possibilities).
A B C D
Sides along the installation site with obstacles
Suction side
In case of an installation site where sides A+B+C+D have
obstacles, the wall heights of sides A+C have no impact on
service space dimensions. Refer to figure 1 for impact of wall
heights of sides B+D on service space dimensions.
In case of an installation site where only the sides A+B have
obstacles, the wall heights have no influence on any
indicated service space dimensions.
NOTE
The service space dimensions in figure 1 are
based on cooling operation at 35°C.
Make sure that there is no danger of fire due to leakage of
inflammable gas.
Ensure that water can not cause any damage to the location in
case it drips out the unit (e.g. in case of a blocked drain pipe).
The piping length between the outdoor unit and the indoor unit
may not exceed the allowable piping length. (Refer to
"6.6. Example of connection" on page 7)
Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturbs
anyone.
Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction. Frontal wind will
disturb the operation of the unit. If necessary, use a windscreen
to block the wind.
Do not install or operate the unit on locations where air contains
high levels of salt, like e.g. in the vicinity of oceans. (Refer for
further information to the engineering databook).
During installation, avoid the possibility that anybody can climb
on the unit or place objects on the unit.
Falls may result in injury.
to keep the refrigerant concentration from exceeding allowable
safety limits in the event of a refrigerant leak.
Excessive refrigerant concentrations in a closed room
can lead to oxygen deficiency.
