Product Support and Installation Contractors.
Foster Refrigerator recognises that its activities, products and services can have an adverse impact
upon the environment.
The organisation is committed to implementing systems and controls to manage, reduce and
eliminate its adverse environmental impacts wherever possible, and has formulated an
Environmental Policy outlining our core aims. A copy of the Environmental Policy is available to all
contractors and suppliers upon request.
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 2078 Handling Refrigerants qualification or equivalent qualification.
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.
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.
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.

The EcoPro G2 range comes as a Full Gastronorm format in a variety of capacities and
temperatures. A standard unit comes with 2/1 shelves (3 with a single model, 6 with a double
model).
The fish model comes fitted with fixed racking to take 7 fish boxes (198kgs) as standard whereas
the wine version comes with a racking assembly that holds either 140x75cl bottles (for a single
model) or 280 x 75cl (for a double model).
The units are manufactured as a one piece shell with easy clean stainless steel exterior. Each
conforms to the current legislation and exceeds the Montreal protocol by using zero ODP (ozone
depleting substances) refrigerants and insulation. There is also the added option of having
Hydrocarbon refrigerant with certain model variations.
Each unit’s temperature is controlled by a microprocessor with digital temperature display. There are
several temperature options available exceeding the Climate Class 5 operations by giving an
ambient temperature to 43°C.
Each temperature display is also easy to read with a wipe clean finish.
The standard form of refrigeration system in this unit is integrated with an air-cooled condensing
unit that allows cooled air to circulate through the evaporator, via the fan into storage areas. It does
this by distributing the refrigerant into the evaporator controlled by a capillary.
Remote systems are also available as an option, the difference being, the evaporator is controlled by
an expansion valve instead of capillary.
Other points to be made on these units are that they have coated coils to prevent corrosion and to
help prolong the refrigerator’s life.
Cabinets come with an easily removable plug box and lid.

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 briefly showing -- followed by the power switch slowly pulsing with a
blank display. The unit is now in 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.
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.

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 1/10 ths 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 ‘Configuration of Parameters’ for information on how to access this).

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 flash. On completion the switch will
return to constant state of illumination.
All Foster G2 cabinets are fitted 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 configuration).
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.
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.

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.

> Wires or electrical components
are in direct contact with metallic
parts.
> Check for appropriate
insulation on the connections
of each component.
Noise
> The refrigerator is not properly
levelled
> Check if the noise goes away
after you level the refrigerator
> The condenser is not fastened
correctly. Copper tubing is in
contact with metal
> While the compressor is
working, check to see if metal
parts are in contact with one
another and/or if the screws
that fasten the condenser are
tightened.
> Check if the fans are securely
fastened. Also, check if the fan
blades are loose, broken or
crooked. If so, change the
faulty blade.
> If the noise persists after all
other measures have been
taken, it may be originating
from the compressor.
