3.0 Description of appliance

The models F(D)v 3613/4613 are dynamically cooled freezers with glass doors and LED lighting. In some versions, the appliances are fitted with castors as a series standard.

A fan draws air from the interior through the evaporator and blows cold air back into the interior.

Temperature control is electronic.

Defrosting is via hot gas.

4.0 Main components and their functions

4.1 Electrical components and functions

Electronics
Type:	Electronic microprocessor control unit from CAREL with digital display
Components:	Electronics housing
Setting range:	-10°C to -25°C
Display range:	-50°C to 150°C
Functions
Temperature alarm:	When: As soon as the value fails to reach or exceeds the target value by 5°C (41°F)
	Audible: Intermittent beep (suppressed during start-up)
	Visual: The alarm symbol is illuminated and the display shows either code HI (too warm) or LO (too cold).
	To avoid unnecessary warnings (e.g. door opening), the threshold value must fail to be reached or be exceeded for at least 15 minutes.
Door alarm:	When: Door open for longer than 10 minutes
	Audible: Intermittent beep
	Visual: The alarm symbol is illuminated and the display shows code "dor".
	If the door is open, the alarm symbol flashes immediately and the temperature display also flashes – the actual alarm is not activated until the above mentioned time has elapsed.
Defrosting:
	Activation: - Automatic, 25 minutes after every new start-up
	- Automatic, every 6 hours.
	- Manual, when the defrost/down button is pressed for 5 seconds.
	Function: Hot gas defrosting (see chap. 4.2.2.2.).
	The defrost water is collected in the electrically heated collection pan and fed into the defrost water evaporation channel through a hose. During the next cooling phase this channel is heated by hot gas and the water evaporates.
	Termination: The defrosting phase is generally terminated thermally14°C(57.2°F).
	If no thermal termination occurs, the defrosting phase is ended after 25 minutes (see chap. 7.5).
	After 2 minutes of drip-off time plus another 4 minutes (due to minimum compressor off time c2 = 6), the compressor will start up again.
	The evaporator fan will start up again 5 minutes after the compressor start.
	Display: The defrost symbol is illuminated during the defrost phase.
	During the defrost phase, the value last displayed prior to the start of defrosting is recorded. The display is reactivated as soon as the target value is once more achieved after the end of the defrost phase, but in all cases within the alarm delay time.
	(The temperature alarm is deactivated for one hour after the end of the phase).
	Special feature: In the event of mains power failure, all times are reset to 0! i.e. the appliance functions normally once the power supply has been restored and will initiate the next defrost phase according to the programmed interval.

Sensors
Air sensor:	Position:	On the left next to the fan, clipped into the fan holder panel.
	Function:	- Generates the display value. The “Update Display” parameter has been set to the highest ...value -> reaction is therefore very muted!
		- Switches the compressor on/off. Hysteresis amounts to -2°C. (E.g.: at a target value of -18°C(0°F) the compressor will switch on at -16°C(3.6°F) and off at-18°C (0°F).
		In the event of an error (interruption or short circuit) the error symbol will be illuminated and the display will show the code E0. -> The appliance will function in emergency mode: 12 minutes on / 15 minutes off
Evaporator sensor:	Position:	On the below of the evaporator, clip on collection pan.
	Function:	- Terminates the defrosting phase at 14°C(57.2°F) In the event of an error (interruption or short circuit) the error symbol is illuminated and the display shows the code E1. -> The appliance will continue to work in normal mode – defrosting will be ended after the time limit has expired
Switches
Door switch:	Position:	In the appliance plinth.
	Type:	Reed Switch
	Contact type:	Make contact with magnet mounted on door
	Function:	The door operates with a reed switch in the plinth panel. This operates make contact reed switch and the magnet on door.
		Switching signal when:
		Door closed:	Door alarm	OFF
			Evaporator fan	ON
		Door open:	Door alarm	ON
			Evaporator fan	OFF
Light button:	Position:	On the control unit.
	Function:	Switches the display and interior light continuously on or off (must be pressed for about 1 second).
Consumers / loads
Door heater:	Position:	In the door frame and on the glass panel
	Function:	Continuously on – prevents condensate formation.
Display lighting(FDv 4613):	Position:	In the display
	Function:	Back-lights the lettering.
LED lighting:	Position:	On the left and right side walls
	Function:	Lights the interior and the goods.
Evaporator fan:	Position:	In front of the evaporator, on the ceiling of the inner liner.
	Function:	Draws out the air and blows it back into the interior through the compressor.
	Special feature:	Compressor run ,fan run. Compressor off, fan off.Exception: When door is open or during defrosting phase!- If the door stays open long enough for the alarm to sound, the fan will start up again.- After termination of the defrost phase, the fan will restart after a time delay.
Condenser fan:	Position:	In front of the condenser
	Function:	Cools the condenser and runs parallel to the compressor
Solenoid valve:	Position:	Behind the compressor
	Function:	Opens a bypass for defrosting, feeding the hot gas directly into the evaporator
	Type:	2/1 valve
Compressor:	Function:	On: Air sensor switch-on value.Off: Air sensor switch-off value.Special feature: The compressor has a restart delay of 6 minutes.Should the compressor be actuated during this time, the compressor symbol in the display will flash (compressor start request). As soon as the compressor is running, the LED will be illuminated.Type:	Standard
Heater for the defrostCollection pan:	Position:	Glued to the underside of the collection pan.
	Function:	Heats the pan during the defrost phase, in order to allow the defrost water to run off.

4.2.2 Function principle

4.2.2.1 Refrigeration

The solenoid valve is closed. The refrigerant runs through the customary circuit.

4.2.2.2 Hot gas defrosting

Defrosting of the evaporator is by hot gas. Before the defrosting phase, the compressor must be running. If there is a defrost request during the compressor idle time, the appliance will cool normally for a minute before the solenoid valve is actuated. This is to ensure that hot gas is available.

When the defrost phase starts, the solenoid valve opens and hot gas flows through the bypass into the compressor. The refrigerant is then cooled down briefly by the ice-encrusted evaporator and is thus liquefied, then subsequently evaporated in the evaporator by the heat of the latter. The gaseous refrigerant which is heated by the dissipated heat from the compressor is then pumped through the circuit.

Fig. 4.2.2.2 / 1

4.2.3 Defrost water evaporation channel and solenoid valve

• The defrost water is collected in the collection pan and fed via a hose to the evaporation channel in the appliance plinth. Here the water is evaporated during normal refrigeration by the dissipated heat of a hot gas line.
• In the defrost phase, the solenoid valve feeds the hot gas directly into the evaporator via a bypass.

5.10.1 Changing over the door hinges

The models are available ex-factory with door hinges on the left (special version).

However, the door is constructed to allow a retrofit change-over of the door hinges (right to left / left to right). This task must be carried out by professional technicians.

The process is largely identical to that of changing the door. However, on the dismounted door, the torsion rod must be changed over and the heater cable worked on.
