Water Coil Maintenance; Checking The Dampers; Control Board Maintenance - Salda AMBERAIR COMPACT S-CX H Operation, Installation & Maintenance Instructions

• In case manual protection is activated, check for a fault before pressing the RESET button. If the fault is identified after it has been rectified,
press the RESET button using a screwdriver or a similar object.
• Electrical heater does not require additional servicing. The filters must be replaced as described above.
• Heaters are equipped with 2 thermal protection devices: an automatic self-resetting protection device that is activated at +50 °C, and a manually
restored protection device that is activated at +100 °C.
• After activation of the manually restored protection device, make sure that the unit is disconnected from the power supply. Wait until all heating
elements cool down and the fans stop completely. After the failure is detected and rectified, press the RESET button before starting the unit.
The failure can be identified by a qualified technician only.

6.7. WATER COIL MAINTENANCE

It is recommended to check the condition of the coil periodically and clean it. Check that the coil plates are not folded and that the seal is tight.
Clean with a vacuum cleaner on the air inlet side or compressed air on the air outlet side. If heavily soiled, cleaning can be done by spraying warm
water with a detergent that does not corrode aluminium. Check that the coil is well drained and that the return water temperature sensor is well
secured.

6.8. CHECKING THE DAMPERS

The incomplete opening of the outdoor air damper creates additional resistance in the system causing excessive energy consumption. If a valve
that does not close completely the water air coil may freeze when the unit is turned off, and cold air will enter the premises undesirably. The mount-
ing and operation of the valve actuator should be checked and adjusted.

6.9. CONTROL BOARD MAINTENANCE

• Open the unit's door.
• Remove the control box cover.
• Disconnect all necessary cables, wires, hoses and connectors in order to remove the control board and unscrew the control board mounting
bolts.
• Remove the control board.
• To reassemble, follow all maintenance steps in reverse order. When re-connecting cables, wires, hoses and connectors, make sure to match
each wire, hose and connector to the corresponding connection terminal and connector.
