11.3. AIR DISCHARGE MODIFICATION
11.4. FILTER ACCESS
The filter can be removed either from the side 1 or from the top 2 without having to dismantle the connection
duct.
The units can be delivered configured either for frontal air return, known as "In LINE" or for side air return. It
is also possible to modify the return air configuration onsite by proceeding as follows:
An outdoor air intake (new air) may be required for ventilation. The blown air temperature must be
controlled in order to avoid the temperature of the mixture of outdoor air and return air at the heat pump
inlet exceeding the appliance’s operating limits. It is also common practice to shut down ventilation during
periods of inoccupation (night time setting of the set temperature).
Each appliance’s ventilation system is generally a sub-system within the building, with its own distribution
duct network. The simple introduction of outdoor air into each return air plenum, quite close to the unit’s
return air intake is sufficient and recommended. New air should not be introduced directly into the appliance.
Provide for a sufficient distance to ensure effective mixing of the outdoor air with the return air. ( Refer to
the § OPERATING LIMITS , page 7).
