WARRANTY WILL NOT COVER EQUIPMENT DAMAGE OR FAILURE THAT IS CAUSED BY IMPROPER
INSTALLATION.
The unit is rated for connection to single-phase ac 120 V/ 60 Hz power supply source.
The unit is equipped with a power cable and a plug and can be connected to any standard grounded outlet. The power cable is
pre-wired to the terminal by default.
The unit must be connected to power supply via the external automatic circuit breaker with magnetic trip integrated into the
fi xed wiring system. The trip current of the automatic circuit breaker must be not below the rated current consumption (minimum
3 A).
Mounting place of the circuit breaker must ensure suffi
cient access for emergency shutdown of the unit.
The cutout fuse is used for overload protection in case of an overload or a short circuit. To replace the cutout fuse disconnect
the unit from power supply source, troubleshoot an overload or a short circuit and then replace the cutout fuse. Check the unit for
operation.

UNIT
CONTROL
Operation modes of the unit:
• Permanent operation or standby mode;
• High-speed ventilation mode.
The unit is controlled using a three-position switch. It enables operation of the unit in the Low Speed Mode, Medium Speed
Mode or Standby Mode, thus providing total air quality control.
The unit changes to HIGH speed mode on a signal from external connected control units.
The LED2 indicator glows during the unit standstill and active power supply.
The LED2 indicator goes down and the LED1 indicator goes on.
Enter the Speed Setup Mode to adjust supply and exhaust fan speed. Individual speed adjustment for each fan is possible over
