The choice of the location of the unit is very important in order to guarantee the unit to work properly. Air flow obstructions, air
circulation difficulties, leaves or other foreign materials that can clog the coils, winds that blow against or excessively favour the
air flow, air stratification or ricirculation effects, nearby heat sources, are all causes of anomalous operating or shut downs of the
unit caused by :
• in cooling mode : condensing pressure increase with performances loss and possible high pressure alarms;
• in heating mode : evaporation pressure decrease with increased number of defrosting cycles and consequent performances loss
and possible low pressure alarms.
For this reason, placement under the ground level or near very high walls must be evaluated very carefully. If the heat pump ope-
rates at temperatures below freezing for extended periods of time, it is important to facilitate the discharge of the water produced
by the defrosting operations to prevent the buildup of ice near the bottom of the machine. During winter operation the heat pump
generates a considerable amount of condensate; make sure that this does not cause any problems to people or property.
On the upper side there must not be any obstruction to the air discharge.
On the inlet and outlet sides guarantee enough space for ducts maintenance.
Respect the free area around the unit as shown in the figure in order to guarantee a good accessibility and facilitate maintenance
and control operations.
