Heat Exchanger; Drainpipe For Condensate; Operation Anomalies - S&P CADB-N-D Instrucciones De Uso

10.2 HEAT EXCHANGER

Using a screwdriver, remove the four screws of the heat exchanger inspection panel bolts.
Rotate the four securing bolts until the panel is free and can be removed.
Using a star screwdriver, release the bolts securing the safety bar located in the angle of the heat exchanger.

10.3. DRAINPIPE FOR CONDENSATE

Regularly inspect the drainpipe for condensates to make sure it is not blocked, if this is the case, remove the obstruction.

11. OPERATION ANOMALIES

ANOMALY
Diffi cult to start.
Insuffi cient airfl ow.
Insuffi cient pressure.
Reduction in performance
after a period of acceptable
operation.
New air temperature too
cold.
Insuffi cient performance of
the exchanger.
Formation of frost on the
exchanger.
Air pulsation.
CAUSE
Reduced power supply voltage.
Insuffi cient static torque of motor.
Blocked pipes and/or inlet points closed.
Fan obstructed.
Filter overloaded.
Insuffi cient rotation speed.
Exchanger package blocked.
Leaks in the circuit before and/or after
the fan.
Damaged roller.
Outside air -5º C or less.
Models (CADB-DI): Thermal protectors
Support resistances open.
Fins dirty.
Outside air below -5º C.
Fan working in fl ow conditions almost 0.
Flow instability, obstruction or bad
connection.
Check motor specifi cation plate.
Close the air inlets to reach the maximum speed.
Change the motor is necessary.
Contact the S&P Post-Sales service.
Clean inlet tubes.
Clean fan.
Clean or replace fi lter.
Check power supply voltage.
Clean the exchanger.
Check the circuit and restore original conditions.
Check the impeller and if necessary, replace with an original spare part.
Contact the S&P post sales service.
Insertion of post-heating resistances.
Contact the S&P post sales service.
Reset by pushing the button RESET, all the thermal protectors of the
resistance.
Clean the exchanger.
