Slimline Cabinet Range Description
The cabinets are manufactured as a one piece foamed shell with the condensing unit located on the base of the cabinet. All the cabinets conform to ISO Climate Class 5 (400c with 40% RH) with the temperature being controlled by a microprocessor with digital temperature display.
The refrigeration system is integral with an air-cooled condensing unit with the refrigerant being distributed into the evaporator controlled by capillary. This cooled air is circulated through the evaporator, via a fan in the storage area. To evaporate condensation, the plastic vaporiser tray has a hot gas line that is inserted into it.
The FSL400H & 800H have a temperature range of +10c to +40c with a timed off cycle defrost.
The FSL400L & 800L are different in that they have a temperature range of -180c to -210c with electric defrost set at 4 times per 24 hours.
The FSL400M & 800 are models designed for meat chilling and have a temperature range of -20c to +20c using
R134a refrigerant.
The coding ‘FSL’ means Foster Slimline with the 400/800 afterwards being the respective net capacity in litres.
If the model comes with an H or L this denotes High or Low temperature units as with a G meaning it has glass doors and M denoting meat.
Both glass and solid doors are fitted with pivot hinges and also both have magnetic door gaskets. Only the solid doors have recessed door handles whereas the glass is surface mounted.
On the glass door models the interior light, incorporating the on/off switch, is fitted to the top of the storage area at the front of the unit. All models fitted with lockable swivel castors to the front and swivel castors to the rear.

Start Sequence
For normal operation
• Press and hold the button for 3 seconds then release.
The current cabinet temperature will be displayed.
If pressed and held for 5 seconds then released this will start the ‘Test Sequence’ .
The test function is a defined sequence of events that will follow a prescribed pattern (dependent upon parameter values) that will operate all electrical elements of the system, simulating a short operating pattern. It should enable an engineer to carryout basic function operations checks of all system parts including refrigeration.
This sequence can take, and the display will count up to, a maximum of 935 seconds before showing ‘ ’. The length of time the test is run will be dependent on the model type and conditions the unit is placed in. After showing ‘ ’ the controller will wait for 1 min, then resume normal operation and show the current temperature of the unit.
To cancel the test sequence prior to completion, press and release

Standby
When pressing the button for 3 seconds, the unit will enter the standby mode and display (unless already in standby and then this will energise the controller to show the current unit temperature).
This ‘ ’ indication will be displayed while the unit is not operating but the mains power is applied to the unit.
This mode may be used for interval cleaning regimes and short periods when the unit is not required. For extend ed periods of inactivity the mains supply should be isolated.

Defrost
Automatic Defrost
Defrost starts automatically as soon as the time set with parameter DFT has elapsed.
> Time Defrost With DFM = TIM defrost takes place at regular intervals when the timer reaches the value DFT.
For example, with DFM = TIM and DFT = 06, a defrost will take place every 6 hours.
> Defrost time count backup At power restoration, if DFB = YES, the defrost timer resumes the time count from where it was prior to the power interruption. If DFB=NO, the time count re-starts from 0. In stand-by the accumulated time count is frozen.
Defrost Type – When defrost has started, compressor and defrost outputs are controlled according to the param eter DTY.
If FID = YES, the evaporator fans are active during defrost.
Resuming Thermostatic Cycle
When defrost is complete, if DRN is greater than 0, all outputs will remain off for the DRN minutes.
Manual Defrost
To initiate a manual defrost press and hold the defrost button for 2 seconds.

English
Fuzzy Logic
’ Fuzzy Logic ’ is an energy saving feature which enables the refrigeration system performance on specific models to be automatically adjusted during operation, for optimum energy performance whilst maintaining the correct internal storage temperature. When enabled it works by identifying periods of high and low usage and applying an appropriate temperature set point and defrost frequency. Additionally the evaporator fan(s) can be caused to cycle (providing ‘air stir’ only) in low usage periods.
‘ Fuzzy Logic ’ operation is controlled by parameter ‘ IISM ’. Setting the value ‘ HDD ’ for this parameter will cause the controller to automatically change between the ‘economy’ and ‘performance’ operating modes (the actual switching point sensitivity is controlled by parameter ‘ HDS ’). Setting ‘ IISM ’ to ‘ non ’ will disable the ‘ Fuzzy Logic ’ function.
When enabled, and upon the product being switched ‘On’, ‘Fuzzy Logic’ will automatically start using the
‘economy’ settings to control the operation of the temperature and defrost (‘ SP ’, ‘ HYS’ , and ‘ DFT ’). The controller will remain operating to the values of these settings unless; through monitoring of the air temperature, evapora tor temperature and door switch (where T2 probe and door switch are fitted), the controller determines that the usage frequency or temperature variation indicates more demanding operational conditions. In such circumstanc es the controller will switch to the ‘performance’ mode (utilising parameters ‘ IISP ’, ‘ IIHY ’ and ‘ IIDF ’). Upon usage or temperature variation reducing sufficiently the controller will revert back to the ‘economy mode’. The evapo rator fan operation works in conjunction with, but separate from ‘ Fuzzy Logic ’. Determined by parameter ‘ FCM ’, and normally set to ‘ TIM ’, the fans will run continuously when the compressor is on, subject to the door switch operation (where fitted). During the compressor off cycle the fans will operate in an ‘air stir’ mode (controlled by parameters ‘ FT1 ’, ‘ FT2 ’ and ‘ FT3 ’). Where ‘ FCM ’ is set to ‘non’ the fans will run continuously. The fan cycle mode during the ‘performance’ operation of ‘ Fuzzy Logic ’ is controlled by parameter ‘ IIFC ’.

Too many door openings
The refrigerator has been overcharged with the refrigerant gas
The refrigerant gas is leaking
The evaporator and/or condenser fans are not working
> Advise user to decrease if possible
> Excessive heat load placed in cabinet >
>
>
>
Advise user not to put in products that are too hot.
Check to see if condensation or ice crystals have formed on the suction line. If so, charge with the correct amount of gas.
Find the location of gas leak in order to seal and replace the defective component. Change the drier. Perform a good vacuum and recharge unit.
Check electrical connections and make sure that the fan blade isn’t stuck.
Replace the fan motor if it doesn’t work.
