7.2.1 Power control
The compressor (CPR) are step-less controlled between, in the frequence converter (FC), set minimum and maximum
frequency.
7.2.2 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.
8 Service and maintenance
8.1 Cooling-technical maintenance
Danger
• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• All electrical connections and maintenance work must be carried out by an authorized installer and in
accordance with local rules and regulations.
Caution
• Operation in the refrigerant cycle and handling refrigerants must be performed by certified personnel.
Care for the Environment!
• The refrigerant must under no circumstances be released into the environment.
An annual inspection, service and check of the cooling technology is required. This needs to be carried out more often
in relation to any special conditions to which the unit is exposed or any local laws and regulations. This is a requirement
for the warranty conditions to be valid.
Suggestions for checks may include:
• Drain trap and draining from tray.
• Any abnormal noises from the compressor(s).
• Loose clamps for fastening pipes and components.
• Oil leaks from pipes or compressor(s).
• General cleaning, vacuuming and if necessary washing using detergent.
• Any corrosion on soldering or pipes.
• Checking for leaks in the cooling circuit.
• Connection of manometer for reading pressure.
• Any refilling with refrigerant R410A.
• Visual checks in sight glass.
• Any replacement of dry filters.
A manometer can be connected from the control panel during operation to achieve normal operating conditions. De-
tailed written reports must be made and handed to the person responsible for keeping a log.
8.2 Electronic expansion valve
The expansion valve is one of the most important components of the cooling system. This is adjusted at the factory and
superheating is 5K.
Warning
If there are any leaks in the refrigerant circuit, Systemair must be contacted for further handling.
