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 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 to storm drains, foul drain, or surface water to soil.

EPro Cabinet and Counter Description

The EPro range comes in two formats, the Full Gastronorm and the Non-Gastronorm.

Both come with a choice of capacities and temperatures, the full format comes with 650x530 shelves whereas the

Non-Gastronorm unit has a smaller shelf measuring 530x550. The EPro range also features Bakery models fitted with racking to take 30

”x18” trays as standard but can be modified to take 60x40cm trays when ordered. (Specially built units will have the prefix „C‟).

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.

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. They have easily removable thermal breaks, giving easy access to the door frame heater while also having a wide magnetic gasket that gives a positive door seal.

Cabinets come with an easily removable plug box and lid, while counters have an easy access condensing unit fitted on the side to make servicing that much easier.

Keypad state lock

Press and hold the button for 3 seconds then release.

If pressed and held for 5 seconds then released 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) that will operate all electrical elements of the system, simulating a short operating pattern. This was designed to provide a quick simple evaluation tool either during manufacturing or service.

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)

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 re-starts 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 enab led, 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). Du ring 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 cycle mode during the „performance‟ operation of „Fuzzy Logic‟ is controlled by parameter „IIFC‟.

Troubleshooting

Problem

Compressor will not start

The temperature is too cold

The temperature is not cold enough

Possible Cause

No voltage in socket

Electrical conductor or wires may be cut

Defective electrical component: thermostat, relay, thermal protector etc

Solution

Use voltmeter to check

Use ohmmeter to check for continuity

Replace defective component

Compressor motor has a winding open or shorted

Measure ohmic resistance of main and auxiliary winding using ohmmeter. Compare with correct values

Change compressor Compressor stuck

Temperature control contacts are open

Incorrect wiring

Fuse blown or circuit breaker tripped.

Power cord unplugged

Controller set too high

Cabinet in defrost cycle

Controller is set at a very cold position

Controller does not disconnect the condensing unit

Control contacts are stuck closed

Defective or incorrect temperature control

Controller is set at a very warm position

Repair or replace the contacts

Check wiring diagram and correct

Replace fuse or reset circuit breaker

Plug in power cord.

Set controller to lower temperature.

Wait for defrost cycle to finish

Set to warmer position and check if the 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

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

Too many door openings

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.

Advise user to decrease if possible

20

Electrical Shocks

Noise

Extreme condensation inside the refrigerator

No illumination (Glass door models only)

Excessive heat load placed in cabinet

The refrigerator has been overcharged with the refrigerant gas

The refrigerant gas is leaking

The evaporator and/or condenser fans are not working

Blocking air flow

Fuse blown or circuit breaker tripped

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

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.

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

Replace fuse or reset circuit breaker.

Check for appropriate insulation on the connections of each component.

The refrigerator is not properly levelled

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

Check if the noise goes away after you level the refrigerator

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

Inspect all connections

Replace the damaged component.

21

Condensing unit runs for long periods of time

Excessive amount of warm product placed in cabinet

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

Dirty condenser coil

Evaporator coil iced over

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.
