SYSAER R32 9. CONFIGURATION OF THE UNIT 9.1. GENERALITIES The unit is designed to be connected to a duct work. The duct network pressure loss must be related to available outdoor pressure of SYSAER R32. 4 discharges and 3 intakes air configurations are available. For each configuration, note the dimensions of the discharge air duct to be provided before the unit arrives on site.
18 SYSAER R32 9.5. ECONOMISER 9.5.1. ECONOMISER - 2 DAMPERS The economiser is an assembly with two dampers connected to servomotors. The quantity of air entering the building varies depending on the given setpoint and enables energy savings in both modes. The economiser is used to ensure modulation of fresh air and recycled air flows in the building.
SYSAER R32 9.5.2. ECONOMISER - 3 DAMPERS It comprises of a set of 3 dampers with an intake fan that enables on the one hand, to combat the pressure loss from the return ducts and on the other hand, to extract vitiated air from the building in order to avoid excessive pressure build ups.
20 SYSAER R32 10. OPTIONS 10.1. CO2 SENSOR RCO2-W RCO2-W room sensor with active/switching output, automatic calibration (can be switched off), for determining the CO2 content in the air (0...2000 ppm / 0...5000 ppm). The transmitter converts the measured values into a standard signal of 0 -10 V or 4...20 mA (switchable).
SYSAER R32 11. INSTALLATION Caution The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work or constructions. Any foreign weight or stress on the unit structure could lead to a malfunction or a collapse with dangerous consequences for personnel and property. In such an event, the warranty shall be null and void.

28 SYSAER R32 14. ELECTRICAL CONNECTIONS WARNING Before carrying out any work on the equipment, make sure that the electrical power supply is disconnected and that there is no possibility of the unit being started inadvertently. Non-compliance with the above instructions can lead to injury or death by electrocution.
Page 31
SYSAER R32 Caution Correction of the excessive centralized power factor (>0.95) may generate transient phenomena dangerous for the motors and contactors of the unit during the start and stop phases. Check instant voltages during these phases. The electric connection of range RT is done in a single point on the level of the principal circuit breaker.
30 SYSAER R32 14.1. GAS DETECTION MODULE The SYSAER R32 unit is equipped with a gas detection module to ensure the safety of the personnel and the machine in case of R32 leakage. Caution The detection system is dependent on the unit’s general power supply. When the unit is not powered, detection will therefore also stop.
