It is important to note that all work should be carried out by a competent person.

Solo plus is a range of self contained refrigeration units for small and large coldrooms comprising hot gas defrost with crankcase protection, capillary control and hot gas vaporisation.

The systems are pre-charged with refrigerant and pre-wired ready for installation into a coldroom with only electrical connections to be made.

Under certain conditions a drain pipe may be required to drain any excess defrost water to an external source

Routine Maintenance

In order to keep the unit operating reliably and efficiently periodical cleaning of the condenser is necessary. (The frequency being determined by site conditions)

This operation is to be carried out with the unit turned OFF. We advise the use of an air jet blowing from inside to the outside. If an air jet is not available then use a soft long haired brush on the outside of the condenser taking care not to damage the fins.

Warning: Condenser fins have sharp edges so care must be taken to avoid injury

Environmental Management Policy.

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 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 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, 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 Reset for Ceiling Mounted Solo Units with the Serial Number Ending in ’H’.

Error in data collection is indicated by the controller displaying ‘EA’, ‘EB’ or ‘EE’.

To restore the controller to the correct operation it is necessary to reset the controller default parameters using the following procedure:

Disconnect the unit from the mains supply.

With the power disconnected press and hold the and switch the power back ON and the letter ‘-C-‘will appear on the display.

After a few seconds the controller will be in reset mode, release and proceed to set the parameters to there correct settings as all of the values would have been set to the default values.

If after completing the reset ‘EE’ persists press and hold

Ceiling Mounted Solo Units with the Serial Number Ending in ’H’ Controller Emergency

Repair.

In case of fault or malfunction of the PCB, an ‘EMERGENCY SYSTEM’ can be used as a short term measure to keep the unit running until a replacement panel can be fitted.

The ‘EMERGENCY SYSTEM’ consists of a terminal board sited on the PCB, fitted as shown on fig1.

Proceed as follows to fit the Emergency System.

1. Switch the PCB off by pressing

Important Note: The PCB should remain in this condition whilst the emergency system is in place.

2. Disconnect the power supply to the unit

3. Connect a thermostat (6 inductive amps) to the terminals E1 and E2, see fig 2.

4. Place a bridge between terminals E2 and E3 as well as terminals E3 and E4, see fig

2.

5. Secure the bulb of the thermostat into the room.

6. Adjust the thermostat to the required temperature and turn the power ON to the unit.

Fig 1

7. When the set temperature is reached the compressor, evaporator and condenser fans will stop.

8. With this system in operation the defrost cycle is not functioning so it is important to limit the amount of door openings to a minimum.

9. When installing the replacement PCB it is important to remove all of the link wires from terminals E2, E3, E4 and the thermostat from E2 and E1 before switching the unit ON. See fig 2.

Controller Operation for Ceiling Mounted Solo Units with the Serial Number Ending in ‘I’

Description of electronic panel

1. Control LED (Green):

LIT: Compressor running, Unit is refrigerating

FLASHING: Compressor is in start delay mode (waiting for signal to start)

OFF: Compressor is OFF. Room is down to temperature.

2. Control LED (Green):

ON: evaporator fan is running.

Flashing: evaporator fan is in start mode.

OFF: evaporator is off. Defrost in operation

3. Control LED (Yellow):

LIT: Unit in defrost mode (auto or manual)

Flashing: Manual defrost mode in operation.

4. Alarm LED (Red):

LIT: Alarm is active – see separate ALARMS section.

OFF: Unit is functioning normally

5. Display: When connected to the mains the display will read OFF indicating the condition of the unit. By pressing the ON/OFF key for 5 seconds the unit will turn ON and display the room temperature. During programming mode the various parameters will be displayed and during alarm mode an alarm code will be displayed.

6. SET/ESC key: Pressed for 3 seconds, the led is lit and setting of required room temperature is enabled. During programming it is used to pass from a sub menu to an upper one.

7. DOWN/ ROOM LIGHT Key: During programming mode or setting of room temperature it serves to reduce the displayed value. At other times it serves to control the room light

8. DEFROST/ UP Key: By pressing for more than 4 seconds it activates a manual defrost.

During programming mode or setting of room temperature it serves to increase the displayed value

9. ON/OFF Key: To turn the unit ON or OFF press and hold for more than 3 seconds.

10. ENTER Key: Permits access to the programming menu and passage to the sub menu.

Access to this programming mode should be by qualified persons only.

Note:

Prior to switching on the unit the following checks should be made.

Connect the mains supply.

All electrical connections are terminated correctly.

All fixing screws are fully tightened.

Having made the pre start checks switch on the unit:

The display will illuminate and OFF appears on the display.

Room temperature settings.

Set the required room temperature.

Turn the unit ON using the ON/OFF key.

Programming room temperature.

To set the required room temperatures press the SET key for more than 3 seconds.

The Green LED will light and the previous set temperature will be displayed.

To increase the set value press the UP key until the desired temperature is achieved.

To lower the set value press the DOWN

On completion press the SET key until the desired temperature is achieved. key or wait 5 seconds for the changes to be saved.
