2.8.1 GSE Aeroevaporators (Unit Coolers) series GSE have the task of optimising the heat exchange between air and
another uid H(C)FC-HFO in a refrigeration system. Inside a casing there is a heat exchanger consisting of
a nned pack interconnected to a tube coil. The ow of relatively warm ambient air, created by the axial fans,
passes through the exchanger where the evaporation of the liquid owing through the tubes takes place, resulting
in the absorption of the heat and the lowering of the outlet air temperature.

6.10 Particular conditions of installation or operation such as low or beamed rooms, overstorage, obstructed intake and
exhaust air circulation and improper ice build-up due to excessive entry of humidity in room may negatively a󰀨ect the
stated performance and may cause defects.
6.11 Standard models may not be suitable for operation in tunnels or blast chilling/rapid freezing cells.
6.12 The units are equipped with axial motorised fans, therefore they are not suitable for channelling or for supporting additional
static heads. Check with Modine for special requirements.
6.13 Verify that the operating conditions (temperatures and pressures) are in accordance to those of project.
6.14 Care must be exercised during the connecting phase in order to avoid possible distortion of the capillary tubes and
shifting of the distributor.
6.15 Fit the appropriate siphons on the condensate drain connections and assess their e󰀩ciency in all working temperatures.
6.16 This unit must be integrated in an industrial electromagnetic environment, which falls within the emission and immunity
limits of the standards currently in force.
6.17 Check that the power supply line is suitable for the electrical characteristics of the unit.
6.18 Check that all electrical connections are in accordance with applicable standards.
6.19 The unit installer and/or plant operator must ensure the presence of an e󰀩cient earthing connection to protect against
indirect electric contacts.
6.20 The units are predisposed for ground wiring connection (see Chapter 8).
6.21 When installing temperature or pressure probes, place them in the most appropriate area: the point cannot be dened in
advance as it varies according to the type of installation and the type of system.
6.22 Place the end of defrost temperature feeler in the coldest areas of the coil, i.e. the areas that tend to freeze more (at the
end of the cycle the unit should be completely ice-free). The position of this device cannot be dened in advance, because
it varies in accordance to the type of cold room and type of installation.

9. Wiring diagrams
Motor-fan connection diagram
Important. The motors are equipped with inner thermal protection with automatic reconnection. Before using motor
speed control systems verify the compatibility with the motors. Non compatible systems may damage motors or incre-
ase noise level; Modine will not be responsible for model performance with speed control systems. For fans equipped
with thermal contacts (TK), these must be connected to the control circuit. For models supplied with wiring in a jun-
ction box, remove the cover to make the connection
Heater connection diagram
Important. Application of adequate thermal control systems on feeder lines is mandatory. Performance of all electric
heaters must be periodically controlled to avoid damage due to ice build-up. Modine is not liable in any way for defects
caused by non detected malfunctions. For models supplied with wiring in a junction box, remove the cover to make the
connection. It is compulsory to use power cables with a minimum cross-section according to the technical standards
in force in the country of installation, depending also on the laying method, the length of the cables and their type. To
minimise the risk of indirect contact, it is advisable to earth the unit, using the earth pole (where present). For further
information please refer to the diagrams supplied with the model.
