Periodical Maintenance - Fral FACSW22.0000 Bedienungsanleitung

1. Connect the internal unit to the outdoor one. There are 4 connectors. Two for water-glycol
(connect the same pipe N°1 with N°1, N°2 with N°2) (C); one for drained condensed water (D)
which is sent to outdoor unit, one which is the electric power supply for outdoor motor-fan (A) and
one for the protection heart connection, (B).
Always connect the outdoor unit with the ground wire!!
2. Insert the socket in an earthed plug.
3. Select desired fan speed
4. Select desired room temperature
5. Move the main switch from OFF position to Cool or Fan position.
The machine should start. If it's set in Cool function and the room temperature is higher than the set
temperature, the compressor after approx. 3,5 minutes starts to work. Led RUN is blinking while compressor is
waiting, it's on when compressor is running.
If the room temperature is lower than the set, machine remains in ventilation but it does not make cool (the
compressor remains off and only the fan is on). Led RUN is off. If room temperature is lower than 18°C,
automatic defrost system can star working; periodically the defrost is performed and only the internal unit fan
works. Thus, Ambient air passes through the evaporator, and the ice falls down as water. Display shows
"dEFr".
After every defrost cycle, machine works regardless environment temperature for 90 seconds in order to move
the air in the room. At the end of these 90 seconds, PCB check thermostat state.
Two maintenance operations are very important:
Cleaning of inside unit air filter, at least monthly, and cleaning of outside unit heat exchanger.
The filter should be cleaned periodically (normally every month), but in dusty rooms it should be cleaned
more often. Remember that when the filter is dirty, the air circulation and, consequently, the machine
performance is reduced.
The inside unit's filter can be cleaned under water flow from a faucet; to remove the filter from the machine, it
needs to take away the lower front grille pushing it upwards and pulling it far from the machine.
For outside unit heat exchanger, cleaning must be done every time that some dust may be seen among the
fins. This operation should be done by an air compressor, pushing the air from outside to the inside of the unit.
