8. Mounting
The power supply rating on unit rating plate must comply with mains rating.
Always disconnect the power supply before opening the unit.
Seifert heat exchangers have an extremely compact design and construction, giving them the advantage of
occupying very little space. In addition, the SLIMLINE HEX models can be mounted externally or recessed, as
required.
To achieve a good seal between the control cabinet and the heat exchanger, the unit's mounting surface on the
control cabinet may need to be reinforced. The air intake and outlet must not be obstructed by equipment
inside the control cabinet, so that the air is mixed thoroughly and thermal stratification is avoided.
For the heat exchanger to work perfectly, the cabinet must be completely sealed from its surroundings. An
imperfectly sealed control cabinet will result in an increased level of condensation. The control cabinet should
have a minimum of IP54 protection, in accordance with IEC 60 529.
Cooling medium connection
There are two pipe connection points in the bottom or in the top of the unit to connect the coolant supply. The
pipe connectors have a G3/8” or G1/2" female thread depending on version. Before connecting the coolant
circuit, note the flow direction of the coolant medium. Next to the pipe connectors, there are labels to identify
the inlet and outlet of the coolant medium. A small indent is also present in the housing next to the inlet port.
To empty the unit connect the water inlet pipe to a compressed air supply and route the water outlet pipe to a
location where the water can be drained. If a solenoid valve is installed on the unit this will be open if the unit is
turned off. Slowly open the compressed air supply till all the water in the heat exchanger is flushed out. Ensure
that the pressure of the system is below the rated pressure of the unit and fitting.
