9.3 Preparing the installation location
!
WARNING Injury
The discharged cold air can cause condensation to be
formed in the vicinity of the air outlet.
 Ensure that no risk of slipping due to wet conditions
or ice formation occurs on adjacent footpaths and
driveways at low temperatures.
 Observe chapter "Sound emissions".
 Ensure that the appliance is accessible from all sides.
 Ensure that the substrate is level, even, solid and permanent.
 Provide a recess (space) in the base to enable supply lines to
be routed into the appliance from below.
9.4 Installing the supply lines
The supply lines are all electric cables plus the flow and return
lines.
- To facilitate connection to the appliance, we recommend
using flexible supply lines in the case of outdoor installation.
 Also protect all supply lines against humidity, damage and
UV radiation by means of a conduit.
 Use only weatherproof cables, e.g. NYY.
 Protect the flow and return lines against frost with sufficient
thermal insulation. The thermal insulation must be at least
twice as thick as the diameter of the pipe. Provide thermal
insulation in accordance with applicable regulations.
 Protect all pipe fixings and external wall ducts with anti-vi-
bration insulation.
Note
When routing the condensate hose, observe chapter "In-
stallation/ Condensate drain".
9.5 Siting
 When siting the appliance, observe the air discharge
direction.
 Position the appliance on the prepared substrate or on a
suitable support.
9.5.1 Siting on foundations or an MK 1 mounting bracket
(HPA-O7SPremium| HPA-O7CSPremium only)
Note
Allow the conduits for the supply lines to protrude slightly
above the foundations. Ensure that no water can enter
the conduits.
