1 Warnings
The following admonitions will be presented in the different sections of the document.
Danger
• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
• Operation in the refrigerant circuit and handling refrigerants must be performed by certified personnel.
Warning
• Beware of sharp edges during mounting and maintenance. Use protective clothing.
• Skin contact with the refrigerant must be avoided. Use protective equipment such as protective goggles,
gloves and suitable clothing’s. Good ventilation must be arranged.
• If freezing injury a doctor must be seen.
• If skin contact the exposed part of the body must be carefully washed.
• If eye contact use eye wash or lukewarmed water and wash for 20 minutes, visit a doctor.
• The units electrical connection to the mains supply must be preceded by an all pole circuit breaker with a
minimum 3 mm gap.
• This product is not intended to be used by children or people with reduced physical or mental ability or
lack of experience and knowledge, if no instruction concerning the use has been given by the person
responsible for their safety or that this person is supervising the operation. Children should be supervised
so that they can not play with the product.

4 Refrigerant Control/Reporting
Topvex SoftCooler TR comes pre-filled with refrigerants and belongs to the group "Piece units containing more than
3kg refrigerants per circuit". Before commissioning shall always a control report in respect of the installation be estab-
lished by a cooling certified person. Leakage control with record keeping shall be done once per year. The installation of
the Topvex SoftCooler TR is only duty to report if the property/enterprise where the installation occurs, all together
after installation, has a total amount of refrigerants of 10 kg or more ("small Piece units" with refrigerants less than 3
kg, e.g. normal refrigerators/freezers does not includes). Reporting shall in occurring cases be done to major inspection
authority (normally the municipal environmental office).
Different regulations can be valid in different countries. Check with your local government.

5.1 General
Control unit (UC) senses the temperature via the extract temperature sensor (ETS) and then keep the set extract tem-
perature 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.
5.2 Cool recovering
Exchanger (HE) will automatically start to recover the cold in the extract air when the extract air is colder then the out-
door air.
5.3 Power control
The compressor (CPR) are step-less controlled between, in the frequency converter (FC), set minimum and maximum
frequency.
5.4 Power limitation
The frequency converter (FC) 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.
5.5 By-pass function (option)
To reduce the energy use for the extract fan when there is no cooling demand the exhaust by-pass damper (accessory)
is opened and thereby the exhaust air does not pass the condenser (CO). At stopped unit all dampers are closed.
