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, 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 clien t‟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 to storm drains, foul drain, or surface water to soil.

Slimline Cabinet Range Description

The cabinets are manufactured as a one piece foamed shell with the condensing unit located on the base of the cabinet. All the cabinets conform to ISO Climate Class 5 (40

0 c with 40% RH) with the temperature being controlled by a microprocessor with digital temperature display.

The refrigeration system is integral with an air-cooled condensing unit with the refrigerant being distributed into the evaporator controlled by capillary. This cooled air is circulated through the evaporator, via a fan in the storage area.

To evaporate condensation, the plastic vaporiser tray has a hot gas line that is inserted into it.

The FSL400H & 800H have a temperature range of +1

0 c to +4

0 c with a timed off cycle defrost.

The FSL400L & 800L are different in that they have a temperature range of -18

0 c to -21

0 c with electric defrost set at 4 times per 24 hours.

The FSL400M & 800 are models designed for meat chilling and have a temperature range of -2

0 c to +2

0 c using

R134a refrigerant.

The coding

„FSL‟ means Foster Slimline with the 400/800 afterwards being the respective net capacity in litres. If the model comes with an H or L this denotes High or Low temperature units as with a G meaning it has glass doors and M denoting meat.

Both glass and solid doors are fitted with pivot hinges and also both have magnetic door gaskets. Only the solid doors have recessed door handles whereas the glass is surface mounted.

On the glass door models the interior light, incorporating the on/off switch, is fitted to the top of the storage area at the front of the unit. All models fitted with lockable swivel castors to the front and swivel castors to the rear.

Keypad state lock

Press and hold the button for 3 seconds then release.

If pressed and held for 5 seconds then re leased this will start the „Test Sequence‟.

The test function is a defined sequence of events that will follow a prescribed pattern (dependent upon parameter values). In turn it will operate all electrical elements of the system, simulating a short operating pattern. This was designed to provide a quick and simple evaluation tool to use either during manufacturing or when servicing.

To cancel the Test Sequence

Press and release the button during the test sequence.

If not pressed the test will continue and when complete the controller will wait for 1 min, then resume normal operation.

(The controller will count to 530 then show „end‟. It will then show the current unit temperature)

Access to the menu and information displayed

Press and immediately release button

With button or select the data to be displayed

Press button to display the value

To exit from the menu, press button or wait for 10 seconds.

Set point: Display and modification

Press button for at least half a second to display the set point.

By keeping button pressed, use button or to set the desired value (adjustment is within the minimum SPL and the maximum SPH limit)

When button is released, the new value is stored.

While keeping button pressed, use button .

Standby

When pressing the button for 3 seconds, will allow the controller to be put on a standby or output control to be resumed (with SB = YES only). When on Standby

Selection of second parameter group

will be displayed.

It is possible to select control parameters between two different pre-programmed groups, in order for the fundamental control parameters to be adapted to changing needs. Changeover from Group I to Group II (and visa versa) may take place Manually by pressing for 2 seconds (with IISM = MAN), or Automatically when heavy duty conditions are detected (with IISM = HDD), or when IISM =D12 and the Auxiliary Input D12 is activated (the activation of D12 selects Group II). If IISM = NON, switchover to Group II is inhibited. The activation of Group II is signalled by the lighting up of relevant LED on the controller display.

Defrost

Automatic Defrost.

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 the power

–up, if DFB = YES, the defrost timer resumes the time count from where it was left off before the power interruption. Visa versa with DFB=NO, the time count restarts from 0. In stand-by the accumulated time count is frozen.

Defrost type

Once defrost has started, compressor and defrost outputs are controlled according to parameter DTY. If FID

=YES, the evaporator fans are active during defrost.

Resuming Thermostatic Cycle

When defrost is over, if DRN is greater then 0, all outputs will remain off the DRN minutes, in order for the ice to melt completely and the resulting water to drain.

Manual Defrost

To initiate a manual defrost press and hold the defrost button for 2 seconds.

Fuzzy Logic

‟Fuzzy Logic’ is an energy saving feature which enables the refrigeration system performance on specific models to be automatically adjusted during operation, for optimum energy performance whilst maintaining the correct internal storage temperature. When enabled it works by identifying periods of high and low usage and applying an appropriate temperature set point and defrost frequency. Additionally the evaporator fan(s) can be caused to cycle (providing „air stir‟ only) in low usage periods.

„Fuzzy Logic‟ operation is controlled by parameter „IISM‟. Setting the value „HDD‟ for this parameter will cause the controller to automatically change between the „economy‟ and „performance‟ operating modes (the actual switching point sensitivity is controlled by parameter „HDS‟). Setting „IISM‟ to „non‟ will disable the „Fuzzy Logic‟ function.

When enabled, and upon the product being switched „On‟, „Fuzzy Logic‟ will automatically start using the

„economy‟ settings to control the operation of the temperature and defrost („SP‟, „HYS‟, and „DFT‟). The controller will remain operating to the values of these settings unless; through monitoring of the air temperature, evaporator temperature and door switch (where T2 probe and door switch are fitted), the controller determines that the usage frequency or temperature variation indicates more demanding operational conditions. In such circumstances the controller will switch to the „performance‟ mode (utilising parameters „IISP‟, „IIHY‟ and „IIDF‟).

Upon usage or temperature variation reducing sufficiently the controller will revert back to the „economy mode‟.

The evaporator fan operation works in conjunction with, but separate from „Fuzzy Logic‟. Determined by parameter „FCM‟, and normally set to „TIM‟, the fans will run continuously when the compressor is on, subject to the door switch operation (where fitted). During the compressor off cycle the fans will operate in an „air stir‟ mode (controlled by parameters „FT1‟, „FT2‟ and „FT3‟). Where „FCM‟ is set to „non‟ the fans will run continuously. The fan cycl e mode during the „performance‟ operation of „Fuzzy Logic‟ is controlled by parameter

„IIFC‟.

Troubleshooting

Problem

Compressor will not start

Possible Cause

No voltage in socket

Electrical conductor or wires may be cut

Defective electrical component: thermostat, relay, thermal protector etc

Compressor motor has a winding open or shorted

Solution

Use voltmeter to check

Use ohmmeter to check for continuity

Replace defective component

Measure ohmic resistance of main and auxiliary winding using ohmmeter.

Compare with correct values

Compressor stuck Change compressor

The temperature is too cold

The temperature is not cold enough

Temperature control contacts are open Repair or replace the contacts

Incorrect wiring Check wiring diagram and correct

Fuse blown or circuit breaker tripped. Replace fuse or reset circuit breaker

Power cord unplugged Plug in power cord.

Controller set too high

Cabinet in defrost cycle

Set controller to lower temperature.

Wait for defrost cycle to finish

Set to warmer position and check if the

Controller is set at a very cold position

Controller does not disconnect the condensing unit

Control contacts are stuck closed compressor stops according to controllers operating range.

Check the insulation of the thermostat.

If problem persists, change the thermostat

Change the control. Check amperage load

Defective or incorrect temperature control

Controller is set at a very warm position

Determine correct control and replace.

Adjust to colder setting

Condenser is dirty

The refrigerator has been placed at an inadequate location

Compressor is inefficient or there is a high pressure due to the air in the system

Iced up evaporator coil

Restriction in system

The refrigerator has been used improperly

Clean condenser

The unit must not be near stoves, walls that are exposed to the sun, or places that lack sufficient air flow.

If there is air in the system, purge and recharge

Check temperature control, refrigerant charge, and defrost mechanism.

Remove all ice manually and start over.

Locate exact point of restriction and correct

The shelves must never be covered with any type of plastic or other material that will block the circulation of cold air within the refrigerator.

Too many door openings

Excessive heat load placed in cabinet

The refrigerator has been overcharged with the refrigerant gas

Advise user to decrease if possible

Advise user not to put in 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.

18

Electrical Shocks

Noise

Extreme condensation inside the refrigerator

No illumination (Glass door models only)

Condensing unit runs for long periods of time

The refrigerant gas is leaking

The evaporator and/or condenser fans are not working

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.

Check electrical connections and make sure that the fan blade isn‟t stuck. Replace the fan motor if it doesn‟t work.

Re-arrange product to allow for proper

Blocking air flow air flow. Make sure there is at least four inches of clearance from evaporator.

Fuse blown or circuit breaker tripped Replace fuse or reset circuit breaker.

Wires or electrical components are in direct contact with metallic parts.

Check for appropriate insulation on the connections of each component.

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

The evaporator and/or condenser fans are loose

Compressor has an internal noise

Loose part(s)

Controller is set at a very cold position

The outside environment‟s relative humidity is very high (over 75%)

The refrigerator door wont shut completely

The refrigerator had been placed at an inadequate location

The light switch is “off” position

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.

Locate and tighten loose part(s)

Set the controller to a warmer position

& check to see if compressor stops as should.

This type of occurrence is caused by local climatic conditions and not by the refrigeration unit.

Check the door and/or the magnetic gasket. Adjust the door hinges if needed; replace the gasket if broken.

The unit must not be near sources that produce too much heat.

Press the light switch to

“on” position

False contact on the light switch, the fluorescent tube, or the ballast

Light switch, ballast and/or fluorescent tube are damaged

Excessive amount of warm product placed in cabinet

Inspect all connections

Replace the damaged component.

Prolonged door opening or door ajar

Door gasket(s) not sealing properly

Advise user to leave adequate time for products to cool down

Advise user to ensure doors are closed when not in use and to avoid opening doors for long periods of time.

Ensure gaskets are snapped in completely. Remove gasket and wash with soap and water. Check condition of gasket & replace if necessary

19

Dirty condenser coil

Evaporator coil iced over

Notes

Clean condenser coil

Unplug unit and allow coil to defrost.

Make sure thermostat is not set too cold. Ensure that door gasket(s) are sealing properly. Select manual defrost and ensure system works.
