The organisation is committed to working with suppliers and contractors where their activities have the potential
to impact upon the environment. To achieve the aims stated in the Environmental Policy we require that all
suppliers and contractors operate in compliance with the law and are committed to best practice in environmental
management.
Product Support and Installation contractors are required to:
1. Ensure that wherever possible waste is removed from the client’s site, where arrangements are in place all
waste should be returned to Foster Refrigerator’s premises. In certain circumstances waste may be disposed of
on the client’s site; if permission is given, if the client has arrangements in place for the type of waste.
2. If arranging for the disposal of your waste, handle, store and dispose of it in such a way as to prevent its escape
into the environment, harm to human health, and to ensure the compliance with the environmental law. Guidance
is available from the Environment Agency on how to comply with the waste management ‘duty of care’.
3. The following waste must be stored of separately from other wastes, as they are hazardous to the environment:
refrigerants, polyurethane foam, and oils.
4. When arranging for disposal of waste, ensure a waste transfer note or consignment note is completed as
appropriate. Ensure that all waste is correctly described on the waste note and include the appropriate six-digit
code from the European Waste Catalogue. Your waste contractor or Foster can provide further information if
necessary.
5. Ensure that all waste is removed by a registered waste carrier, a carrier in possession of a waste management
licence, or a carrier holding an appropriate exemption. Ensure the person receiving the waste at its ultimate
destination is in receipt of a waste management licence or valid exemption.
6. Handle and store refrigerants in such a way as to prevent their emission to atmosphere, and ensure they are
disposed of safely and in accordance with environmental law.
7. Make arrangements to ensure all staff who handle refrigerants do so at a level of competence consistent with the
City Guilds 2079 Handling Refrigerants qualication or equivalent qualication.
8. Ensure all liquid substances are securely stored to prevent leaks and spill, and are not disposed of into storm
drains, foul drain, or surface water to soil.
Disposal Requirements
If not disposed of properly all refrigerators have components that can be harmful to the environment.
All old refrigerators must be disposed of by appropriately registered and licensed waste contractors,
and in accordance with national laws and regulations.
General Electrical Safety
Foster Refrigerator recommends that the equipment is electrically connected via a Residual Current Device; such as
a Residual Current Circuit Breaker (RCCB) type socket, or through a Residual Current Circuit Breaker with Overload
Protection (RCBO) supplied circuit.

Cabinets & Counters with FD1-11 and FD1-14 Controller
Start-Up and Operation
Initial Set Up
After unpacking clean and allow the cabinet to stand for 2 hours before turning on.
Ensure the cabinet is situated where neither hot nor cold air sources will affect its performance. Make sure that
a minimum clearance of 310mm above and 50mm around the cabinet is available for ventilation and effective
operation.
Initial Start up
Connect the unit to a suitable mains power outlet and turn the supply on. Please do not plug or unplug the unit with
wet hands.
The cabinet will energise briey showing followed by the power switch slowly pulsing with a blank display. The
unit is now in standby.
(Some icons or switches are only visible during adjustment, when activated by parameters or through operation/
manual selection).

Standby
Pressing this switch for 3 seconds will turn the unit on (the switch backlight is static and the display shows the
operating temperature) or put into standby (the switch backlight pulses slowly on & off).
As the operating temperature has been pre-set no adjustments are required. Allow the cabinet to reach its normal/
set operating temperature before loading.
User Adjustment Mode
You are required to enter this mode to make any setup changes.
These include Set Point, Keypad Security and display of T1, 2 or 3 probe temperatures.
Press and immediately release after which the and switches will ash/pulse together.
Press to scroll through the following screens:
To exit this mode scroll back to the adjustment screen and press or wait for 30 seconds and the display will revert
to the normal display showing the operating temperature.
Set Point and Other Mode Adjustments
Access the adjustment mode as described above. Using the or switches to scroll to the mode that requires
adjustments i.e ‘Set Point’ this is the minimum temperature the cabinet is allowed to cool down to (the display shows
the temperature and ash/pulsing icon ).
To adjust this press and release the icon will show constantly. Adjust the setting with the or switch. Conrm
the change by pressing and releasing again, the next mode will automatically show. Scroll through the modes with
the or switch until you return to the adjustment screen and press and release to exit and save.
If at any point the display is left for 30 seconds it will revert to the normal display and no
changes will be saved.
Increased Sensitivity of Temperature Settings
If you require the cabinet to have a more accurate or increased sensitivity to temperature and the warnings this
controls, the controller is able to measure temperature in 1/10ths of a degree (0.1°) instead of whole degrees.
With parameter ‘SC’ set to ‘1C’ the display will show the temperature as 1/10ths of a degree on the scale between
-9.9°C to +9.9°C.
Also, with parameter ‘SC’ set to ‘1F’ the controller has the facility to show the temperature in Fahrenheit (between
-58°F to 99°F). However if this is selected all other temperature related parameter values will have to be set
accordingly to this change. (See ‘Conguration of Parameters’ for information on how to access this).
Keypad Security Settings
Access the ‘Keypad Security’ screen as described above.
The screen will show the current status, initially preset to ‘ ’, with ashing. Press and release and will
show constantly. (If you modify this setting with to show ‘ ’ the keypad will be locked, will show constantly
and the cabinet will not be able to be put into standby, carry out a manual defrost, adjust temperature set point,

To switch on the lights press and release so that the switch backlight is on continuously.
To switch off press and release and the switch backlight will ash/pulse.
Downloading Data
This option is only available when enabled via parameters and the cabinet has the additional FCOM1 device
available –this availability will be shown by the data switch being constantly illuminated.
To download the data the switch should be pressed and then released. The information will then begin
downloading to the appropriate printer or PC and the backlight of the switch will ash. On completion the switch will
return to constant state of illumination.
Defrost
All Foster G2 cabinets are tted with a fully automatic defrost system to ensure that the evaporator coil remains
free from ice during normal use. Melt-water is evaporated using either the heat from the refrigeration system or a
separate electric heater (dependent upon model and conguration).
To activate a manual defrost – while the cabinet is in ‘run’ mode press and hold for 5 seconds. After 3 seconds
the display will go blank then return after a further 2 seconds. At this point a defrost will be performed (subject to
underlying operating parameters), this will terminate automatically.
Reduced Energy Control Mode
The reduced energy control mode (‘e’ mode) detects when the unit has reached the selected temperature set-point
and the operating conditions (such as usage rate) have become less demanding.
When enabled, the controller will modify the compressor, evaporator fan and defrost operation in order to reduce the
energy consumed. During the reduced energy control mode is illuminated at the bottom right corner of the display.
Upon an increase in operating demand the controller reverts back to the standard operating settings with the
symbol extinguished. The ‘e’ mode is enabled by setting parameter ‘iiM’ to ‘Au’. Further parameter settings (‘iiS’,
‘iit’, ‘iiP’, ‘iiY’, ‘iiF’, ‘iid’, and ‘iiE’) control the temperature cycle during the reduced energy control mode. Setting
parameter ‘iiM’ to ‘no’ disables the ‘e’ mode.

Start-Up and Operation
After unpacking, clean and allow the cabinet to stand for 2 hours before turning on.
For units that have been delivered outside the UK, please remove the compressor strap as instructed on the
front of the unit, before connecting the unit to the mains supply.
Ensure the cabinet is situated away from both hot and cold air sources, as this will affect its performance. Make sure
that a minimum clearance of 150mm above the cabinet is available for ventilation and effective operation. Connect
the unit to a suitable mains power outlet and turn the supply on. Do not plug or unplug the unit with wet hands.
After connecting the unit to the mains the display will briey show a dash in the centre of the screen. This will then
show .

Cancel Test Sequence
The test function is a dened 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.
Standby
If already in standby and then this action will energise the controller to show the current unit temperature.

Internal Light Operation for Glass Door Models
Where tted the light can be turned on or off by pressing and releasing the button.
Defrost
Automatic - 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
parameter 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.
