INTRODUCTION

CABINET DESCRIPTION

The cabinets are manufactured as a one piece foamed shell.

The condensing unit is located on the base of the cabinet.

The cabinets conform to ISO Climate Class 4. (320c with 40% RH)

Temperature is controlled by a LAE microprocessor control with digital temperature display.

The HR 120, LR 120, HRB 120, LRB 120, HR 200, LR 200, HR 240, LR 240, HR 360 and LR 360 refrigeration system is
integral with an air-cooled condensing unit with the refrigerant distribution into the evaporator controlled by capillary.

The HR 140, LR140, HR 150, LR 150, HR 410 and LR 410 refrigeration system is integral with an air-cooled
compressor and static condenser with the refrigerant distribution into the evaporator controlled by capillary.

The HR 120, LR 120, HRB 120, LRB 120, HR 200, LR 200, HR 240, LR 240, HR 360 and LR 360 are forced air cooling.
The air is circulated through the evaporator, via the fan/s into the storage area.

The HR 140, HR 150 and HR 410 are forced air cooling. The air is drawn over the evaporator and through the fan/s
blowing into the storage area.
The LR 140, LR 150 and LR 410 have static freezer shelves with circulation in the storage compartment by natural
convection.
The HR 120, LR 120, HRB 120, LRB 120, HR 200, LR 200, HR 240, LR 240, HR 360 and LR 360 have a plastic
vaporiser tray with the hot gas line inserted into it to attain vaporisation.

The HR 140, HR 150, HR 200, LR 200 and HR 410 condensate vaporisation is provided by a self contained condensate
vaporiser tray attached to the top of the compressor.

The HR 120, HRB 120, HR 140, HR 150, HR 200, HR 240 and HR 360 are timed off cycle defrost.

The LR 120, LRB 120, LR 200, LR 240 and LR 360 have electric defrost set at 4 times per 24 hours.

The LR 140, LR 150 and LR 410 refrigeration is provided by static freezer shelves requiring manual defrost.

The doors are fitted with pivot hinges, stainless steel door handle and magnetic door gasket.

All models are fitted with roller castors to the rear and M8 adjustable levelling bolts to front.

On glass door models the interior light is fitted to the top of the storage area at the front. The on/off switch is
incorporated in the light.

Nomenclature based on –

H = High Temperature.
L = Low Temperature.

R = Refrigerator.

120/ 140/ 150/ 200/ 240/ 360/ 410 = Net Capacity (litres).
F = Forced Air.
S = Static Shelf.

2. Controller and Operation.

BIT 20B11E and BIT 20B22E used upto 00-00-2005

The BIT 20B11E is fitted to the HR150, LR150, HR200, HR360, HR410 and LR410 (Foster part No. 00-554860).
The BIT 20B22E is fitted to the LR200 and LR360 (Foster part No. 00-554166).
The LAE BIT 12 RU front display fitted to both controllers (Foster part No. 00-554167).

They are a two piece controller, the Control Unit is fitted at the rear of the cabinet with the Display Unit fitted into
the front top right hand side of the cabinet, interconnected by a ribbon cable.
Defrost type for HR models is a timed off cycle.
Defrost on the LR120, LRB120, LR 200, LR240 and LR360 is electric.
To defrost the LR150 and LR410 switch the machine off and allow the ice to melt, once it is clear of ice dry the
cabinet thoroughly before switching the machine back on.
A manual defrost, for the HR models and the LR120, LRB120, LR 200, LR240 and LR360, can be initiated by
pressing the red button on the control unit or by pressing the upward and downward arrows on the display
simultaneously. During defrost the air temperature is displayed.
One probe is fitted measuring air temperature and is used to control cabinet temperature.
In the event of probe failure “E1” will be displayed.
In the event of air probe failure on HR models the refrigeration system will be controlled by a timed sequence. The
controller parameter setting cF is set at 00 which allows for the compressor to be on for 3 minute and off for 4
minutes.
In the event of air probe failure on LR models the compressor will run continuously, the controller parameter setting
cF is set at 1.
On the LR120, LRB120, LR 200, LR240 and LR 360 an evaporator probe is fitted, in the event of probe failure “E2”
will be displayed. If the evaporator probe fails defrost will be controlled on a timed basis.
