5. 1 GENERAL 1 1 Range of Application The COMPACT Unit and COMPACT Top are complete air handling units with built in control equipment The air handling units are designed for comfort ventilation and can be utilised in smaller buildings such as offices schools day nurseries public buildings shops and residential build ings The COMPACT Unit air handling units have duct connec tion spigots on their end panels whereas the COMPACT Top units have them at the top The type of unit can therefore be selected on the basis of the amount of space available for installing it and for arranging the ducts The COMPACT Unit and COMPACT Top are one piece air handling units If supplementary function sections such as dampers and air coolers are required they must be in stalled in the ductwork In order to fully obtain all the benefits the COMPACT system has to offer it is important keep in mind the air handling unit s special characteristics in conjunction with designing the project installing the unit adjusting it and operating the system The unit must be installed indoors Important Always read the safety precautions in Section 2 that explain the risks involved in running the unit and designate who shall be permitted to operate and service the unit and carefully follow the installation instructions provided in each paragraph The product identification plate is situated on the top of the air handling unit Refer to the particu

8. Economy Cooling BOOST Economy first uses a higher airflow to cool the premises before a start signal is transmitted to the cooling machines The function can also operate without the cooling func tion being activated On a cooling load the flows are slowly increased up to preset maximum flow When the flows are up to max and if a cooing load is still present the output contacts for cooling are activated The cooling boost function requires an outdoor air tem perature of at least 2 C lower than the extract air tempe rature for it to be activated Normal cooling operation is activated if the temperature difference is too small Sequence The cooling BOOST Sequence is used if a cooling machine is sized for a higher than normal cooling flow If there is a cooling load the flow is increased up to the preset max flow before the cooling function is activated The cooling function is delayed 1 minute after the airflow is increased The cooling boost sequence is blocked if no cooling func tion has been selected Comfort Economy Cooling BOOST Comfort Economy is a combination of the two variants for increasing the airflow If the conditions for Cooling BOOST Economy are met the unit will begin increasing the airflow before the cooling unit starts up If the conditions for outdoor air are not met the flow in crease will begin when the supply air temperature reaches the preset Min permissible temperature Economy
