VENTILATION
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 "Operating limits").
