5 Transport and storage
The Topvex SoftCooler should be stored and transported in such a way that it is protected against physical damage that
can harm panels, handles etc. It should be covered so that dust, rain and snow cannot enter and damage the unit and
its components. The appliance is delivered in one piece containing all necessary components, wrapped in plastic on a
pallet for easy transportation.
When transporting the Topvex SoftCooler use a forklift, but once installed on the floor avoid transfer, the feet can damaged due to lateral loading.
Warning
• The unit is heavy. Be careful during transport and mounting. Risk of injury through pinching. Use
protective clothing.
• Be careful so the unit doesn't tip over.
6 Installation
6.1 Unpacking
Verify that all ordered equipment are delivered before starting the installation. Any discrepancies from the ordered
equipment must be reported to the supplier of Systemair products.
6.2 Where/how to install
Topvex SoftCooler are meant for indoor installation. Place the unit on a horizontal flat surface. It’s important that the
unit is completely levelled before it is put into operation.
The electronic components should not be exposed to lower temperature than 0° C and higher than +50° C.
The following max. temperatures applies for an interference-free operation of the Topvex SoftCooler:
• Outside air max. +33 °C
• Extract air max. +28 °C.
• Ambient temperature max. +28 °C.
When choosing the location it should be kept in mind that the unit requires maintenance regularly and that the inspection doors should be easily accessible. Leave free space for opening the doors and for taking out the main components
(figure 1). General maintenance includes among other things inspection and cleaning of the drip tray and flange coils.
A floor drain must be available in the room so that the condensation water can be drained off (chapter 6.6)
Avoid placing the appliance against a wall, as low frequency noise can cause vibrations in the wall even if the fan
noise-level is acceptable. If this is not possible it is recommended to carefully insulate the wall.

6.4.1 Assembley the Topvex SoftCooler SR
Fig. 6 Left hand unit (right hand units are mirrored)
Make sure that the sealing stripes and faces in-between the units halves are undamaged. Place the SoftCooler between
the two air handling units parts and carefully push them completely together. The SoftCooler is joined to the air handling parts by 4 M10 screws, one in each corner.
1. Remove the cover plate on top of Softcooler to access the inner upper mounting screw on the SoftCooler side that
faces the rotary heat exchanger.
2. Remove the exhaust air filter to access the inner upper mounting screw on the Softcooler side that faces the exhaust
air filter.
3. Remove the supply air fan to access the inner upper screw on the Softcooler side that faces the supply air fan.
4. When all 4 screws are in place remount the supply air fan, the exhaust air filter and the cover plate on top of the unit.

Installation |
6.5 Condensation and Heat Insulation
Outdoor air duct and discharge ducts must always be well insulated against condensation. Correct insulation installation
on ducts connected to the unit is especially important. All ducts installed in cold rooms/areas must be well insulated.
Use insulating covering (minimum 100 mm mineral wool) with plastic diffusion barrier. In areas with extremely low outdoor temperatures during the winter, additional insulation must be installed. Total insulation thickness must be at least
150 mm.
Caution
• If the unit is installed in a cold place make sure that all joints are covered with insulation, and tape well
• Duct connections/duct ends should be covered during storage and installation
• Do not connect tumble dryers to the ventilation system
6.6 Condensation drain
Warning
The unit is not to be taken into operation before the included condensation drain and water seal are
connected from the Topvex SoftCooler to the floor drain.
The drain is to be connected to the drain connection under the drip-tray. The drip-tray is located in the bottom of the
Topvex SoftCooler.

7.1 General
Control unit (UC) senses the temperature via the extract temperature sensor (ETS) and then keep the set extract temperature by sequence controlling the compressor (CPR), heat exchanger (HE) and hot water- /electrical heater (HWL/H,
ELH). The temperature sensor in the supply air (SS) is min. and max. limiting the supply air temperature.
7.2 Power control
The compressor (CPR) are step-less controlled between, in the frequency converter (FC), set minimum and maximum
frequency.
7.3 Power limitation
The programmable controller is continuously sensing the condensing pressure via the high pressure sensor (HPS) and
gradually slows down the speed of the compressor (CPR), if the pressure exceeds the set limitation value. This is done
to avoid a high pressure alarm.
Note:
This instruction contains functions for the Topvex SoftCooler SR, for a complete description of functions see
