RELATIVE HUMIDITY
: Max. 90%
ATTENTION!
The temperature limits should be adhered to, to avoid damage to the pump.
C2. ELECTRICAL POWER SUPPLY
1. During installation and maintenance, make sure that the electric supply lines are not live.
2. Always turn off the switch before supplying electrical power.
3. Check the correct rotation direction of the DC pump. If it is inverted, check the polarity of the connection
cable.
a) RED cable: positive pole (+)
b) BLACK cable: negative pole (-)
ATTENTION!
Power from lines with values outside the indicated limits can damage the electrical components.
C3. WORKING CYCLE
1. Extreme operating conditions with working cycles longer than 30 minutes can cause the motor temperature
to rise, thus damaging the motor.
2. Each 30-minute working cycle should always be followed by a 30-minute power-off cooling phase.
3. MAXIMUM BY-PASS TIME: 3 MINUTES.
