Environmental Management Policy for Service Manuals and Duets.

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, redu ce 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
clients 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, oils.

4. When arranging for disposal of waste, ensure a waste transfer note or consi gnment 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 ensu re 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 to storm

drains, foul drain, 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.

Controller Description

The controller is mains voltage 230-50/60-1

00 - 555941

Set-Temperature Chilling LED

Timed Chilling LED

Degree Celsius LED

Storage LED

Alarm LED

The device has the following operational states:

• ‘ON’ the controller is switched on and an operating cycle is running.

• ‘stand-by’ the controller is switched on but no operating cycle is running.

• ‘off’ the controller is switched off

If there is a power failure during a timed blast chilling operation, when the power is restored, chilling will continue from
the point at which the interruption occurred.
If there is a power failure during a set temperature blast chilling operation, when power is restored, chilling will start
from the beginning.
If there is a power failure during the storage operation, when power is restored the storage operation will be continue.

Controller operation

Prior to starting a chill operation ensure the controller is in the ‘stand-by’ mode.

Timed chill operation

To place the controller in ‘stand–by’ press for 2 seconds, whilst in stand-by the cabinet internal air
temperature will be displayed intermittently.

Press ‘PoS’ will be displayed and the Timed Chilling LED will be flashing.
Press to display the chilling time, set to 90 minutes as standard, if no change to the time is required press

to start the programme.
If changes to the chill time are required press ‘PoS’ will be displayed and the Timed Chilling LED
will be flashing, press to display the chilling time followed by to decrease the time or to

increase.
During chilling the display will show the time remaining with the Timed Chilling LED on.
Once the chilling time is completed the controller switches to the storage mode with the display showing ‘End’ press
any button to mute the alarm, press to cancel the message.
Whilst the cabinet is in the storage mode the internal cabinet temperature will be displayed and the Timed Chilling LED
and Storage LED will be illuminated.
To stop the programme press for 2 se conds

NOTE:
If changes are made to the time settings on completion of the programme the time will revert back to the default setting
of 90 minutes.

Temperature chill operation

Place the controller in ‘stand–by’ pressing for 2 seconds.
Ensure that the food probe is inserted into the product prior to commencing the temperature chill programme.
Press ‘PoS’ will be displayed and the Timed Chilling LED may be flashing, if it is Press
again to display Set-Temperature Chilling LED flashing.
Press the display will show the product end temperature, +3ºC as standard, if no change to the temperature
is required press to start the programme.
If changes to the chill termination temperature are required press ‘PoS’ will be displayed and the Set­Temperature Chilling LED will be flashing, press to display the chilling temperature followed by
to decrease the temperature or to increase.
Once the product temperature has been achieved the controller switches to storage mode with the display showing
‘End’ press any button to mute the alarm, press to cancel the message.
Whilst the cabinet is in the storage mode the internal cabinet temperature will be displayed and the Set­Temperature Chilling LED and Storage LED will be illuminated.
To stop the programme press for 2 se conds

NOTE:

If changes are made to the temperature settings on completion of the programme the temperature will revert back to
the default setting of +3ºC.
