Frequently Asked Questions - VLS 096A RF SDD VESTFROST

How to start the device after installation?

After connecting the solar panels (MC4 cables), clean the device, then turn it on using the ON/OFF switch. Wait approximately 6 days at 43°C for the ice ballast to form. When the display shows approximately +4°C in the morning, the device is ready for vaccines.

What temperature should the vaccine compartment show?

The temperature must be between +2°C and +8°C. Record it each morning and evening using the thermometer. If it falls outside this range, contact a technical supervisor.

How to defrost the freezer?

Defrost when the frost layer exceeds 4-5 mm. Turn off the power using the ON/OFF switch, remove the water containers, open the lid, unscrew the drain plug, place a tray under the drain. Use a basin of hot water (not boiling) in the freezer, close the lid, wait 30 minutes, then remove the frost with a plastic scraper. Never use sharp objects or electrical devices.

What to do if the compressor does not start?

Wait a few minutes, as the compressor may require several attempts. Check that the solar cables are properly connected and undamaged. Check the fuse condition and replace if necessary. If nothing works, call a technical supervisor.

How to clean the device?

Disconnect the power using the ON/OFF switch. Use warm water with a mild unscented detergent and a soft cloth. Rinse with clean water and dry thoroughly. Avoid water entering the control panel. Clean the seal regularly with clean water.

Can I use multiple sockets at the back?

No, it is prohibited to place multiple portable sockets or portable power sources at the back of the device. The device must be plugged directly into a suitable socket.

What is the procedure in case of power outage?

The device operates on solar energy, so grid power outages do not affect its operation. In case of lack of sunlight, the compressor may stop. The frozen water containers help maintain the temperature. Monitor the temperature and avoid opening the lid unnecessarily.

How to maintain the solar panels?

Clean the panels from dust once a week with water. Check monthly that no shading (trees, buildings) reduces production. Annually, check electrical connections and mounting hardware, and tighten bolts after 2 weeks and then each year.

What to do in case of water leakage in the vaccine compartment?

The automatic drain may be blocked. Regularly clean the drainage filter (fig. 17) with warm water and a mild detergent. Make sure the drain plug is tightly screwed. If water persists, contact after-sales service.

How to dispose of the device at end of life?

Do not dispose of the device with household waste. The insulation contains a flammable blowing agent. Take it to a collection point for waste electrical and electronic equipment (in accordance with directives 2012/19/EU and 2006/66/EC). Contact your town hall or municipal waste disposal service.

Introduction

The philosophy behind the VLS 096A RF SDD system is:

• Simplicity
• Safety
• Robustness
• Reliability

The VLS 096A RF SDD system is composed of:

• Vaccine refrigerator and Waterpack freezer - Solar panels • Installation equipment for the solar panels - Wires from the solar panels to the VLS 096A RF SDD.

The VLS 096A RF SDD is a vaccine refrigerator and a waterpack freezer. It has one compartment for vaccine storage (+2°C to +8°C) equipped with 1 basket and one compartment for storing and freezing waterpacks.

With correct installation and by following a few maintenance routines, the system will work trouble-free for many years.

Operational guidelines

The compressor requires that the solar panels are able to deliver a power above a certain threshold in order to start. When started, the compressor is able to operate at lower power consumption than the starting threshold. The compressor may need a couple of starting attempts to get running. So be patient!

During days with changing weather conditions, the compressor may start and stop several times.

The noise coming from the appliance is low, and primarily comes from a fan cooling the compressor.

The compressor is almost noiseless. The fan starts a moment before the compressor and stops a moment after the compressor.

The controller is factory set and should be adjusted only by authorized personnel.

Basket is included when the appliance is supplied and is proposed to be used for arranging vaccine storage.

Maintenance and cleaning

Maintenance of the appliance

Daily maintenance:

The temperature in the vaccine compartment must always be monitored on the thermometer every morning and evening. Please note that the vaccine in the appliance may not freeze. The temperature is factory set, and should not be adjusted by unauthorized personnel.

Check that the lid is properly closed and fits tightly to the cabinet of the appliance.

Monthly maintenance:

Clean the grille on the back side of the refrigerator once each month.

Yearly maintenance:

Electric connections and components are to be checked and cleaned once a year or more if necessary.

Maintenance of the solar panels Weekly maintenance:

The solar panels are to be cleaned for dust once each week – or as required. Cleaning must be carried out with water using a soft cloth or wash rag.

Monthly maintenance:

Avoid shading

It should be regularly monitored that shades do not come up such as new towering trees, as this will decrease the amount of energy produced by the system.

Yearly maintenance:

Electric connections and components are to be checked and cleaned at least once a year or more often if required. Because of risk of fire, it is necessary to remove dust and dirt. Check that PV panels are clean, free of fractures, scratches, corrosion, moisture penetration and browning.

Cabling should be checked to ensure it is secure.

Check the mounting hardware to ensure it is in good condition and ensure the earth connection is continuous.

Check junction boxes to ensure there is no water accumulation and that the integrity of lid seals, connections and clamping devices is intact.

All bolts and nuts are to be re-tightened 2 weeks after installation, and then once a year.

Cleaning

Disconnect the power supply before cleaning by using the on/off switch placed at the junction box at the rear of the appliance. The best way to clean the appliance is by using lukewarm water with a small amount of unscented detergent. Never use cleaning agents that scour. Use a soft cloth. Rinse with clean water and dry thoroughly. It is important to prevent water from running into the control panel.

The sealing strip around the lid must be cleaned regularly to prevent discolouration and prolong service life. Use clean water. After cleaning the sealing strip, check that it continues to provide a tight seal.

If the appliance is not being used for any period of time, switch the appliance off, disconnect the power supply, empty the appliance, clean the inside, and leave the lid open to allow air circulation and prevent smells.

Defrosting

The water-packs stored and the humidity of the air gradually causes frost and ice to form in the freezer compartment. A thin layer of frost or ice does not affect freezer performance, but a thick layer could cause the freezer not to cool water-packs satisfactorily. Small amounts of loose frost can be removed using a plastic scraper.

Never use electrical apparatus or sharp implements as these may damage the inside of the appliance.

When the layer of frost and ice exceeds 4-5 mm, the freezer should be completely defrosted.

Defrosting should be performed in the morning between 7am to 9am, just before the solar radiation again is powerful enough to start the compressor and run the refrigeration system.

Proceed as follows:

1. Disconnect the power supply by switching off the ON/OFF button. Important! ONLY switch off the power supply of the freezer compartment.
2. Remove all water-packs from the freezer compartment. Place them in an empty coldbox or wrap them up to keep them as cold as possible.
3. Keep the freezer lid open.
4. Unscrew the drain plug placed on the front right-hand side underneath the appliance.
5. Place a tray under the defrost water drain.
6. Place a bowl of hot (but not boiling) water in the freezer, close the lid and wait approx. 30 minutes before removing loose frost with the plastic scraper.
7. To prevent water from damaging the floor during defrosting, it is advisable to check the defrost water tray from time to time and to cover the floor around the defrost water drain to protect against ice and splashes. When all the frost and ice have melted, clean the inside cabinet, as well as the lid, lid gasket, and outside of the cabinet using water with a mild, perfume-free detergent. Dry the freezer with a soft cloth, and make sure no moisture is remaining after cleaning.
8. Reinsert the internal and external drainage plugs, and check that the lid gasket is not faulty.
9. Important! Screw back in position the drain plug, and turn on again the power supply with the ON/OFF button.
10. Check waterpacks are not leaking before returning them to the freezer compartment. Place waterpacks according instructions, approx. 5 minutes after having switched it on. Close the lid.

fig. 15

Drain

The appliance is equipped with an auto-drainage function, with a drain hole at the bottom of the vaccine compartment.

The drain is collecting the water droplets generated by the unavoidable condensation that at some point will be created on the inner linings of the vaccine compartment, due to the fact of warm air hitting the cold surface of the wall.

This condensation eventually will run down the sides to the bottom, and water then flows down the drain tube into a drip tray located on top of the compressor which evaporates the liquid as it warms.

If the appliance drain becomes blocked by any objects, the water can't drain away as it should from the vaccine compartment, which will result in water accumulating, which further could result in creating issues with the stored vaccine vials, stickers, cardboard boxes, etc.

This is why it is an important SOP procedure, to regularly ensure that the drain filter is clean and free from dirt and waste.

To do the cleaning, use lukewarm water with a mild cleaning agent on a soft cloth, and wipe off the filter along with the surrounding bottom.

Finish off with a dry dishtowel or similar, to ensure all objects are removed and the bottom is dry.

This is why it is an important SOP procedure, to regularly ensure that the drain filter fig.17 is clean and free from dirt and waste.
