Operation of the Solar therm Units

• During sunlight hours, energy from the sun is converted into electrical energy, which is used to cool the product. Any excess energy is stored in a ballast load ( Phase Change Material ) and is used during low light & low energy conditions.

• The cooling system has no battery storage and comprises of the refrigerator and 2 x 90 watt Photovoltaic panels

MC72-Medical Unit

• This equipment is designed for hospitals, clinics, and ambulances. This Chest Type unit comprises of two compartments:

-Vaccine storage-Freezer compartment.

• A mechanical damper regulates the amount of cooling and keeps it between 2°C and 8°C.

• The dampers and controller are preset to achieve optimum vaccine temperatures in all ambient temperature conditions.

• Ample insulation also allows for vaccines and medicines to be safely stored for extended periods of time in low light conditions.

LC86-Commercial Merchandiser

• This is a commercial merchandiser comprising of controller and BD35k compressor. Beverages are stored in a basket suspended from the top of the cabinet.

• The unit has a ballast load. The remainder of the space is filled with product. The controller is pre-set to achieve optimum beverage temperatures in all ambient temperature conditions.

LS150-Domestic• This unit is designed for the

storage of fresh food, and is aimed primarily at rural homesteads and areas with intermittent power supply from the national grid.

• It is a single door design with separate fridge and freezer compartments that are able to maintain temperatures from 2°C to –9°C.

• Ample insulation also allows for food to be safely stored for extended periods of time in low light conditions.

• The controller is preset to achieve optimum fresh food temperatures in all ambient temperature conditions.

Data Collection• Performance data ( temperature & power

consumption ) is logged electronically.

• Alarms ( door open etc ) also logged.

• Data is transmitted daily via the telephone network to a website.

• The website collates the data from all the various loggers worldwide and presents it in a readable pictorial format.

• Anyone can ascess the website and review the test data.

Troubleshooting GuideFAULT

Compressor is notrunning, and the icepacks are not cold

Compressor is running,and the temperature istoo high

Temperature in solar-therm is too low

No temperature isdisplayed

The ventilation grill is blocked.

The lid is not closed properly.

The fan in the compressorcompartment is blocked or defective.

The temperature in the room in whichthe appliance is installed is too high.

The internal lid is not placed properly.

The display battery is flat.

POSSIBLE CAUSE

Be patient, it is most likely that thecompressor will start within a fewminutes

REMEDY

if this is not the case, check thefollowing:-check that power is connected andthat the wire from the solar panel tothe appliance is intact.-if the above is OK, call technicalsupervisor.

Ensure unhindered air circulation.

Ensure that the lid is closed properly.

Check that the fan is running, if notit should be replaced.

shield the appliance against directsun light and ensure more ventilationto the room.

Ensure that the internal lid is placedcorrectly.

Change the battery. See section:service
