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.

Initial Set Up
After unpacking, clean and allow the cabinet to stand for 2 hours before turning on
(cleaning directions supplied within this manual). 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 10cm around the cabinet is available for ventilation and effective operation.
Install the drip tray underneath the cabinet after placing the unit in position.
Connect the unit to a suitable mains power outlet and turn the supply on. Do not plug or unplug the
unit with wet hands.
Standby
When left for several minutes the cabinet will automatically switch to standby, this helps reduce
energy consumption.
When in standby mode the cabinet will show the middle LED on the main display flashing green
slowly.
During this time the controller is still connected to the mains and standby does not cut off the main
power supply. As a consequence only the compressor and condenser are switched off during this
time.
If the cabinet is going to be unused for a prolonged amount of time than the units power supply
should be switched off and or disconnected from the mains supply.
To exit standby press any button on the keypad and the controller will revert to displaying the
current temperature.

Button Description
Button 1 –Decrease/ Information - This button is used as a decrease button and when pressed
will show the current controller information i.e. time remaining when using a cycle and the current
temperature.
Button 2 –Choice of Cycle & Increase - From here you can select either ‘Soft Chill’ or ‘Defrost’
cycles. By selecting this button the LED for the relevant cycle will illuminate. From this point you can
use button 3 to confirm and launch the selected cycle.
This is also used as an increase button when amending parameter values.
Button 3 –Start/Launch Cycle - This will start a cycle and then the LED’s around this button
(LED 3) will illuminate in a circular chase pattern confirming the action. If pressed and held this
button will also stop a cycle.
Before starting a cycle we advise that you bring the cabinet down to temperature for
optimum performance. Select a Soft Chill Cycle (as described below) but only run this for
15 minutes. To stop after this time press and hold the Start/Launch button until the cycle
stops. Warning ‘rEG’ will show on the display to acknowledge that the cycle didn’t
complete as determined by the parameters, this will clear after selecting your preferred
cycle.
Selecting a Soft Chill
Activate a cycle by pressing the ‘Select Cycle’ button until the ‘Soft Chill’ LED is illuminated. Press
the ‘Start/ Launch Cycle’ button to start the cycle. The cabinet will decide if this cycle should be run
by a probe or timer mode at the start of the cycle (as described below).
Cycle Run Type
After pressing the ‘Start/Launch Cycle’ button and the unit will automatically detect if the cabinet
should run in a ‘Probe’ or ‘Time’ cycle. A ‘Probe’ cycle is determined by the temperature read from
the food probe already inserted in the product at the start of the cycle. The ‘Time’ cycle is
determined if the food probe is not inserted in the product at the start of the cycle. Please Note: If
this button is pressed without selecting either a Soft Chill or Defrost cycle the unit will
continually run on a probe detection cycle until 90 minutes is up and there is no
temperature control with this type of cycle.
Defrost & the Drip Tray
Check no foreign bodies obstruct the waste in the base of the cabinet. The drip tray is situated
underneath the cabinet and should be emptied regularly as water will collect here.
There are two methods of defrost:
> Natural Defrost
Turn the cabinet off at the mains and or stop any cycles. Leave the cabinet door ajar and the
frost will melt and collect in the drip tray.
> Forced Defrost
Press the ‘Select Cycle’ button followed by ‘Defrost Cycle’.
Press the ‘Start/Launch Cycle’ and a defrost will take place showing LED 2 illuminated.
Modifying the End of Cycle Time or Temperature
While the current cycle is running press button 3. You will then be able to use buttons 1 and 2 to
increase or decrease the values.
Stopping a Cycle or Function
It is possible to stop or interrupt a cycle at any time by pressing the ‘Start/Launch’ button and
holding for several seconds. After doing this ‘rEG’ will show on the display to acknowledge that the
cycle didn’t complete as determined by the parameters.
End of Cycle Alarm
At the end of each cycle the audible alarm will sound to notify the user. This can be silenced by
pressing any button on the keyboard.

Important: Before cleaning or the removal of any parts, the unit should be put into
standby and then the power supply should be turned off at the mains.
Please do not plug or unplug the unit with wet hands. Only when cleaning has been
completed and the unit is dry should the cabinet be turned back on at the mains. Using
high pressure water jets or lances is prohibited; the warranty policy will not cover
problems that result from failure to heed the above warning.
Removing the Unitcover
You should only be required to remove the unitcover for access to the condenser, compressor and or
controller electrics.
Remove both the fixing screws situated at the bottom on the unitcover. Tilt the cover forward and
pull towards you. Refitting is the same action but in reverse ensuring the fixing screws are refit.

Cleaning the Condenser
XR10 & XR20 models will clearly see the condenser after removal of the unitcover.
XR35 model will have to also remove the Condenser Fan Plate and motor.
To do this unscrew the two fixing screws positioned on
The top of the condenser fan plate.
Tilt the plate forward on the rubber pivots and
then remove from the unit. You will now be
able to access the condenser for cleaning.
Once the unitcover is removed please do not leave the unit unattended.
Cleaning the condenser should be scheduled every 3 to 6 months and carried out by a service
engineer. Use a soft brush or vacuum cleaner to remove dirt/dust.
If there are any stubborn grease deposits left on or through the condenser call your supplier to carry
out a full service (this is normally chargeable). Failure to maintain the condenser may invalidate the
warranty of the condensing unit and cause premature failure of the motor/compressor. DO NOT use
a wire brush to clean the condenser. Re-fit any panels removed after cleaning.
Access to the Evaporator
After opening the door you will be able to see the evaporator assembly situated at the rear of the
cabinet.
>Firstly, remove all shelves or pans and ladderacking before trying to proceed with the
following instructions.
>To remove the fan and or guard unscrew the guard fixings and pull it towards you.
>To access the reducer valve, evaporator coil and air probe, remove one or more of the
locking screws and then pivot the fan motor baffle on its rubber mounts. This baffle can be
totally removed if required.

now remove the door from the upper hinge bracket.
To refit reverse these instructions and make sure to refit the
spacer washer.
(The unitcover is only visible on this image for illustrative
purposes)
Door Gaskets
Door gaskets should be inspected on a regular basis and replaced if damaged. To clean, wipe with a
warm damp soapy cloth followed by a clean damp cloth. Finally thoroughly dry before closing the
door.
Regular Cabinet Cleaning
As and when required remove all product and shelving (beware of cold and or sharp components)
from the unit. Clean exterior and interior surfaces with mild liquid detergent, following the directions
on the pack at all times. Rinse surfaces with a damp cloth containing clean water. Never use wire
wool, scouring pads/powders or high alkaline cleaning agents i.e. bleaches, acids and chlorines as
these may cause damage. Dry the unit thoroughly before re-using.
Shelves, Pans and Supports
Shelves, Pans and their supports should be removed to clean. The shelves and pans are dishwasher
safe; however the supports should be cleaned with warm soapy water then rinsed and dried.

Corrosion Issues –Listed below are the most common reasons of corrosion on Stainless
Steel. Before reporting any issues of corrosion please ensure the following has been adhered too.
>Floor Cleaner –Splashes of floor cleaner can cause signs of corrosion on the cabinet
base and side panels. This is due to floor chemicals being a lot higher in acidity then
standard stainless cleaner. Also the vapour from these chemicals can hang in the air and
prolong the damage.
>Incorrect Use Of Cleaning Products –Bleaches, acids and soda have a high acidic
content and should be avoided on the cabinet’s internal and external parts. Only stainless
specific products should be used or warm soapy water. Even when using these methods a
clean warm water wipe down should be used to ensure all chemicals have been removed
from the panels. Drying the unit thoroughly can also help.
>Area Where Water/ Chemicals Can Gather –As build-up of product could gather
on/in the cabinet likewise this can also gather in nearby gulley’s, drains etc. Please
ensure these are also run clean of any chemicals.
>High Temperatures - Cleaning solutions can become more aggressive when used with
and in high temperatures. Ensure temperatures do not exceed 60°C thus avoiding
blackening of stainless steel surfaces.
>Salt and Brine - If salt or foods containing a brine is used within the area of the blast
chiller pitting in the stainless could be visible if not cleaned regularly. Any spillage of salt
or brine should be cleaned off the surface first by a soft cloth and then rinsing with warm
soapy & clean water.
>Chlorination –at times water chlorine levels can be high and this can have a corrosive
effect on stainless. Although rare this is a factor that should be made aware of.
