4.1 Location
Transportation and Handling
Handles
<Figure 4.1.1>
The heat pump unit is delivered on a wooden pallet base with
cardboard protection.
Care should be taken when transporting the heat pump unit that
the casing is not damaged by impact. Do not remove the protec-
tive packaging until heat pump unit has reached its final location.
This will help protect the structure and control panel.
• The heat pump unit can be transported ONLY vertically. The max-
imum allowable inclination is 45°.
Module MUST be separated if it can only be transported/
carried horizontally.*
<see How to remove the module>. (during installation)
• The heat pump unit should ALWAYS be moved by a minimum
of 2 people.
• When carrying the heat pump unit use the handles provided.
• Before using the handles, make sure they are securely at-
tached.
• Please remove fixing legs, wooden base and any other
packaging once the unit is in installation location.
* Module removal, carrying and reassembling are installer's re-
sponsibility.
Suitable Location
Before installation the heat pump unit should be stored in a
frost-free weatherproof location. Units must NOT be stacked.

Legs
• The heat pump unit should be installed indoors in a frost free
weather proof location.
• The heat pump unit should be positioned on a level surface
capable of supporting 'it's FILLED weight. (Adjustable feet (ac-
cessory parts) can be used to ensure unit I level)
• When using the adjustable feet, ensure that the floor is strong
enough.
• Care should be taken that minimum distances around and
in front of the unit for service access are observed <Figure
4.1.2>.
• Secure the heat pump unit to prevent it being knocked over.
• Install the heat pump unit where it is not exposed to water/
excessive moisture.
