The cooler is connected to the air duct with a flange connection, fig. 5.
Outdoor installation of the cooler is allowed only if the refrigerant is an antifreeze (ethylene glycol
solution). During mounting consider the operating characteristics of the mixing unit actuator.
While mounting the cooler provide quick and easy dismantling of the heat exchanger, drain pan and
the drain pipe.
The cooler is designed for horizontal installation only to enable condensate drainage.
While mounting the cooler provide enough access for servicing and repair operations.
The duct cooler may be installed upstream and downstream of the ventilation unit. If the cooler
is installed downstream of the fan, provide at least 1-1.5 m air duct between the cooler and the fan for air
flow stabilization.
Prior to starting mounting check the tube, plates and tubular manifold condition. Flanges of the system
components are mounted with galvanized bolts and M8 nuts.
Prior to starting operation and after a long downtime fill the U-trap with water. The supply / air handling
unit may be equipped with a U-trap and a ball valve, especially for the units with negative pressure. This
U-trap must not be filled with water.
