Machine-specific engineering and preparation
»
Ensure suitable structure-borne vibration separation
between the outdoor unit and the installation points
on the roof.
8.1.7 Drainage
Material damage
If drainage for the condensate is inadequate, the
structures underneath may be damaged.
»
Ensure drainage for condensation is sufficient
even at low temperatures.
If it is not possible to provide sufficient drainage outside the
appliance due to lack of space, additional precautions must
be taken to prevent ice from forming under the outdoor unit:
»
Ensure that the mounting feet of the outdoor unit are
at least 100 mm clear of the surrounding terrain so
that the drainage pipe can be installed on the outdoor
unit.
Material damage
If the clearance between the outdoor unit and the
surrounding terrain is > 150 mm, water may pene-
trate from below or may drip down from the outdoor
unit.
»
If necessary install a waterproof plate un-
der the outdoor unit, ensuring a clearance
of 150 mm.
8.2 Refrigerant lines
When laying the refrigerant lines, observe the following
guidelines:
► No bends with centre line radii smaller than 2.5 x the
diameter of the pipe.
► The refrigerant lines must be protected from damage
in normal operation as well as during maintenance,
service work and repair.
► The refrigerant lines must not be routed through
rooms which do not comply with the requirements for
the minimum area of clear floor space in the instal -
lation room. (See page 27, Minimum area of clear
floor space in the installation room)
