10.3 Electrical faults
If compressor start relay have been triggered in the unit cabinet, but the compressor(s) do not start, check the cabling.
The control for the cooling equipment is located in the cooling box; check that operation/alarm relay is activated. This
should be activated when voltage is switched on. If this is not activated, the fault is located in the following:
• High-pressure pressostat.
• Low-pressure pressostat.
• Fault output on converter.
High-pressure pressostats has manual reset and low-pressure pressostats have an automatic reset. Also check whether
there are any fault alerts in the converter display; see the manual supplied for this. If the relay has been activated, but
there is still no operation, check the start relay for the compressor. This relay is activated according to cooling need, and
follow the relays in the main controller cabinet. Check the relay and cabling to it in the event of faults. If relay is acti-
vated and the compressor do not operate see chapter 10.4.
10.4 Faults in cooling technology
Important
Before carrying out any work on the cooling technology within the warranty period, Systemair must be
contacted first, if necessary with any requests for covering costs.
Only authorised cooling companies may carry out work on the cooling circuit. A manometer should be connected and
the pressure checked. The temperatures of the different processes are also checked. Typical faults may be:
Compressor cuts out at low-pressure pressostat:
• Not enough refrigerant
• Insufficient air volume
• Electronic expansion valve defect
• Pressostat defect
Cuts out at high-pressure pressostat:
• Too much refrigerant
• High exhaust air temperature
• Pressostat defect
Freezing of evaporator:
• Electronic expansion valve defect
• Not enough air to the battery
A leak search is to be carried out when leaks are suspected, and during the annual inspection.
11 Description of Geniox Softcooler
11.1 Geniox Softcooler Cooling section
The Geniox Softcooler cooling section is a complete unit for a comfort cooling in air handling systems. In other words,
all electrical and pipe work is completed at the factory, tested and ready for installation. Unit is made from 60 mm Roc-
wool in a sandwich construction consisting of two aluzinc 185 steel plates. (Corrosion class C4).
On the front of Geniox Softcooler there is a large door for easy access to the components. There is also an integrated
control display of frequency converter and control panel door for easy access and inspection during operation. The sec-
tions come in seven different sizes and 12 power variants, all Geniox compatible.
11.1.1 Batteries
The batteries are already fitted in the box with all pipe connections complete. Evaporator and condenser batteries are
mounted on the same side in the box, so that the piping between the batteries is tidy and service-friendly in terms of
access during a service. The batteries fit the unit’s cross-section and use all available area in the air flow. This ensures
low speed and low decrease in pressure. Carry-over of condensation is thus eliminated.
The DX battery is placed in a drip tray to drain condensation. The tray has an external connection for a drain trap.
